Review of career excavators. Other types of chassis

█ The world's best mini excavators. Buy and choose. (Top 10 Overview)

A mini-excavator is a small and pretty lightweight machine that allows you to quickly reach the construction site. However, despite compactness, the technique becomes a real assistant in organizing earthworks. To date, the development of hydraulic systems, improved specifications Allow mini excavators to get closer as much as possible, and in some cases surpass their senior fellow.

In certain situations, and on a number of specific construction sites, we can play on hand not only a small weight of a small excavator, but also its compactness that directly affects its maneuverability and accuracy in work. For example, on narrow urban streets, in low-rise (cottage) buildings, with the foundation of the foundation on aesthetic garden lawn. Mini excavators with the so-called "zero crash" (Zero Tail Swing) will allow you to work in a limited space without clinging for obstacles. In addition, the low mass of the machine will save your lawn and other elements of landscape aesthetics. Unfortunately, in the case of imported mini excavators, including a problem with the cost of customs clearance, a utilization fee, which in turn does the price of the transcendental price. Business on a mini excavator is an interesting thing, and if you go with the mind, you can work well. So what mini excavator is better?

Mini-excavator: what to pay attention to when choosing?

Despite the fact that among earthmoving equipment, the mini-scabers are the most compact, their mass is quite significant. This class of technology includes cars up to 10 tons. Despite the external similarity with heavier models, their functions can sometimes seriously differ from the "giants". We turn to the parameters of this type of technology, which first of all it is characterized.

-Configuration arrows and cabins

The excavator arrow is attached directly to the housing of the excavator or its cabin and keeps the shoulder with the bucket and mounted equipment. There are different configurations of the fastening of the boom. For example, if the boom is fixed, it is attached directly to the excavator housing, and moves only when the machine turns. If the arrow is moving in a horizontal projection - it gives greater mobility and maneuverance when digging.

In addition, there are three options for departure of the tail of the cab of a mini excavator: zero (zero crawling cabins), minimal departure and full departure. The technique with a complete departure is hard to use in a limited space. On the contrary, the system with zero crash of the tail of the cab is ideal for a limited space. Although cabins with minimal departure give a good result when maneuvering in a closed space.

- Engine power and cab design

The mini-excavators are mainly installed diesel engines, the power and the definition of which in turn determine challenges, as well as strength and hydraulics. In addition to the power of the engine in L.S. (kW), matter the number of cylinders and torque. Mini excavators' cabins are open and closed. Of course, the closed cabin is more popular, as it protects the operator from bad weather, dust and dirt on a construction site, however, the cost of such models is in most cases higher.

- chassis and caterpillars

It should be noted that the overwhelming majority of mini excavators have caterpillars as a propulsion (with the exception of a narrowly specialized segment of non-intelligent towed trailed mini-excavators, which we have written earlier.

Caterpillars are installed rubber and steel. Both species of caterpillars have its advantages and disadvantages. For example, steel caterpillars provide greater patency and have greater strength. However, rubber (due to its relative softness) causes less harm to the lawns, sidewalks, a blocking with landscaped work. The chassis is under the excavator body, leading to the traffic of the caterpillar and the car.

The chassis in small excavators is two types: fixed and movable. The first is significantly wider than the excavator housing, which gives additional stability. Nevertheless, in some cases, this parameter will limit maneuverability and mobility in closed spaces. The movable chassis makes it possible to change the wheelbase with the help of hydraulics, narrowing it to the width of the machine housing.

- Hinged equipment

In addition to the wide range of buckets different size Both forms, the operator can use attachments operating from the excavator hydraulic system, such as a yamrub or drilling rig with various augers, a hydraulic hammer for crushing stone, asphalt or beto, and another hitch. Special cargo plugs are also used to move logs, stones, construction trash. In addition, sometimes the mini excavator is used as a mini-crane.

If your choice fell on a mini excavator, and you want to buy or take it for rent, leasing, credit, this technique will pleasantly surprise you with your capabilities. As mentioned above, such a car will show itself well on narrow streets and will retain a lawn by performing a wide range of earthworks.

And if you are limited in the budget and can not afford a new technique, then our review will help you how to choose a mini excavator bu.

Mini Excavator Bobcat E32I T4

This model is a traditional mini-excavator with tail reversal. It is available in three configurations: standard, with an elongated arrow and with a sliding arrow.

This unit has a mass of 3260 kg in the configuration with the base boom. Base version dimensions make up: 4.66 meters - length; 1.52 meters - width and 2.43 meters - extended excavators installed diesel engine With a capacity of 24.8 hp At maximum turns of 2200 per minute. More loaded versions with an elongated and sliding arrow are equipped with turbocharged power units due to the increased mass of the machine.

The speed of the described model of the mini-excavator is 4.5 km / h. The angle of rotation of the boom is 75 degrees left and 55 degrees to the right, which is associated with the design of the rotary hinge. The depth of digging varies from 3.1 meters to 3.9 meters depending on the arrow design in the version you selected.

All three versions in the standard layout are offered to buyers with rubber tracks, but the option of installing steel tracks is available for wanting. As previously mentioned, the unconditional advantage of rubber caterpillars is their "anti-vandality" on lawns, a fragile blocking and on some other surfaces. However, steel caterpillars give better permeability and by themselves significantly exceed rubber threatening and durability.

The mini-excavator Bobcat is offered in versions with an open cabin with a roof or with a fully closed cab. The cabin has air conditioning with a stove, radio, comfortable seat. The dashboard informs the operator about the engine speed, the coolant temperature, there is a fuel level indicator, a meter meter and so on. As an option, it is possible to install a more technological dashboard with a color display, invincible launch and a throttle position indicator.

The perfectly developed hydraulic system of the E32I machine provides a calm and smooth management of the technique, allows you to safely switch between different functions in accordance with the mounted mounted on arrow (for example, a hydrobur, hydraulic hammer and so on). The hydraulics control mode is determined by the operator of the mini-scale, based on the installed equipment and allows the machine to respond differently to the movement of the pilot joystick.

Bobcat offers various types of hits. It is a boring, buckets of various types and sizes, a bump, a special grasp for logs and construction waste, bulldozer dump, hydraulic scissors and others. Quick disconnect hydraulic connections and the X-Change Bobcat system will allow you to comfortably and quickly replace the necessary attachments.

The E32I model with an elongated arrow certainly gives additional opportunities to the mini-scale, however, the standard tail departure of these models limits the maneuverability of the car, in contrast to the models of competitors with a minimum or zero tail departure.

Mini Excavator Caterpillar 301.5

The described model is mini-excavators of the so-called starting (initial) level. This mini-excavator weighs 1672 kg. It is easy and compact, can work on easy-damaged surfaces (lawn, paving), as well as under the tilt up to 30 degrees, which certainly gives additional features. The gearbox has two speeds reaching 2.25 km / h and 4.34 km / h, respectively. Obviously, the first speed is essentially a worker, and to move on the workplace from the object to the object it is more convenient to switch to the second, unless of course "accelerate" will allow the landscape. In addition, the presence of two speeds allows you to use a variable of craving depending on the type of surface and the properties of the soil.

The machine has a 17,4-strong diesel atmospheric power unit Caterpillar 3003 with water-cooled, having 4 cylinders reaching 2,200 revolutions per minute.

The arrow has such an angle of rotation at which the operator is perfectly visible to the digging process. Cat 301.5 has a standard tail departure of a cab hanging over caterpillars. With the length of the caterpillar of 1.4 meters, a significant crash departure can interfere with working in a limited space.

The buyer proposes two options for the operator space of the operator - this is an open canopy and a closed full-fledged cabin. In Oyah, options are provided with robic hanger, glove box, working sensors and indicators on dashboard. The seat is available in two versions - vinyl and fabric. Obviously, the vinyl seat is more resistant to nature whims and is suitable for a vest with a canopy. On the contrary, a more comfortable fabric seat is an option for a closed all-weather cockpit. Of course, a more expensive version of the mini-excavator with the cab has additional optionsIn particular: the stove, defrostor, internal lighting and wiper. There are no some options available for competitors, for example, no air conditioner, radio, invincible start, color screen. However, whether such "grazers" are needed in a shredder - a big question.

For the model, the use of additional hinged equipment. These include of various types Buckets, borants, hydraulic bumps. Additional hydraulic equipment is the original, called Quick Coupler Caterpillar. However, this "Origality" will not compromise you without refinement to connect freely optional equipment Funny from the brand Cat.

Model 301.5 is not among competitors the easiest or most powerful, but its strength is enough to close to the performance of full-size machines, and its relative ease will allow you without fears to drive the excavator to your well-kept country site with landscape design. Its substantial disadvantage, as mentioned above, is a significant cabins. However, this constructive feature It is also characteristic for many other fellow travelers of neighboring brands.

Mini excavator Hitachi ZX10U-2

The model is a small excavator with a zero craft tail (Zero Tail Swing), the Yanmar motor and the width of the caterpillar database. This is a rather lightweight excavator weighing a little more than 1,100 kilograms, which has the following dimensions: 2.96 meters - length and 1.46 meters - width.

This little excavator carries a powerful turbocharged Yanmar brand engine. The diesel power unit has three cylinders, reinforced turbine. Engine volume - 845 cm3, Power - 12.7 hp, Maximum revs - 2100 per minute. Such parameters of the power plant allow you to reach a speed of 4 km / h, while the speed of movement is 2 kilometers per hour. The fuel supply in the tank is 19 liters, the hydraulic system has a volume of 25 liters.

Hitachi ZX10U-2 has a radius of an electric cabin of a cab of 0.8 meters, which makes it possible to attribute it to the technique with zero departure of the cab tail, because with such parameters, the cab does not go beyond the gabarite of the tracked propeller. As it was said in joining our review, such a configuration is ideal for working between walls, trees, that is, in any limited space. In addition, this convenience is complemented by an adjustable width of the tracked base, which allows changing the actual width of the machine from the maximum one - 1 meter, to the minimum - 90 centimeters. Of course, a wider base gives greater stability, but in some cases, for example, if necessary, drive into a narrow doorway, this function is simply indispensable.

This mini-scab is quite limited by the amenities of the operator. The car does not even have a canopy, not to mention a full-fledged closed cabin. In stock Only the rear folding safety arc. With such features, keep in mind that protection against bad weather and building dust is essentially absent, which is quite essential for Russian latitudes.

From the facilities of the pilot there is a safety belt, a 12 volt socket, backlight. There is no stove and air conditioning, no radio, no hangers for working clothes. There is not even a cup holder. In fact, in addition to levers (joysticks), pedals and triggers, there is only an analog dashboard in the operator space. Dumping the excavator is adjusted mechanically and does not have a hydraulic line. The machine has the driving part of the tractor type on the rubber-tracked propulsion, which is convenient when working on an easily damaged surface - a lawn, pavement, paving. The chassis has three supporting rollers.

With a significant lightness of this excavator, the Hitachi model does not have a lack of power, and the zero wave of the tail of the cockpit allows you to work in a closed space. In addition, the variable latitude of the base allows you to pass especially narrow areas on a construction site. The excavator rental is most likely to be cheaper, since the car is easily transported in a simple passenger car. In fact, the only substantial disadvantage of this Japanese excavator is essentially the lack of any amenities of the operator of this mini-excavator, however, the price of a mini-excavator greatly wins in the fellow.

Mini Excavator John Deere 50G

This mini brand excavator John Deere. It has a mass of 4790 kg, which is not so little for the excavator of this class. However, this feature is more than compensated by a spacious and comfortable cabin of the operator, large and efficient working tools, as well as the powerful railway engine of the world leader Yanmar.

Reverse our gaze on power installationInhaling life into it is pretty heavy among the constructions. So, that's diesel engine Janmar volume of 1.6 liters having 4 cylinders corresponding to all world environmental and technical standards and related to the class of heavy engines. This unit provides 36 "horses" forces at 125 Newton / meters of torque and revolutions up to 2400 per minute.

From the power of the engine, other features flow, in particular, despite the fairly large mass of the excavator, it has a rather greater speed, which "classmates" of our hero are unlikely to boast. On this compact excavator, you can ride with the breeze, disperse up to 6.77 km / h. At the same time, its minimum speed is 4.18 km / h, which exceeds the maximum speed of any nearest analogue.

We pay special attention to the tail departure of mini excavators, which, in our case, is zero (or minimal, depending on the configuration), which, you see, for such an impressive car is an extremely important indicator. This reduces the risk of damage to the tail of the cockpit at the construction site, and also allows our mini-special scavenger to maneuver in a limited space.

Rubber caterpillars are installed on John Dir 50G, but unlike analogues, they carry steel cores, which significantly increases their service life. At the same time, the rubber propulsion retains all its advantages on a gentle lawn or a historical fragile blocking. This is especially true, given the mass of our hero - almost 5 tons! In addition, it is possible to install pure steel tracts, but it is better to do not go to the lawn with them without anything needed. There is also a variant of steel caterpillars with rubber softeners.

Comfortable cabin is just our case, because 50G carries all the amenities necessary to the operator. "Steering cutting" is spacious, has a comfortable entrance, anti-skid wrapping. There is a cupboard, a 12-volt "cigarette lighter", climate control (!) And display, showing motorcycles, as well as sensors indicators of the engine and hydraulic oil. In the cockpit, both mechanical and hydraulic control of the machine is present.

The compact excavator has control levers with a short convenient move, the arrow of the pendulum type and folding pedals, a reduced transmission lever and other amenities within reach. For the installation of mounted equipment, the mini excavator has an original BRS system, which unfortunately allows you to work only with brand hits John Dir.

In conclusion, I would like to say that the mini excavator John Deere 50G is a powerful multi-functional apparatus, which in its functionality and capabilities closely close to the class of large excavators, in fact, rather to the middle of the size class of midi excavators (Mini Excavator Strong & Heavy ). Its absolute versatility attracts attention. For this, there is a powerful engine, and the zero taking of the tail of the cabin, rubber or steel tracks. However, its size, mass and cost is still great for a compact excavator. But if you still solved this mini excavator to buy, and not take, for example, for rent, you will not regret it. it excellent machine!

Mini Excavator Kobelco SK35SR-5

The Kobelco SK35SR-5 mini excavator is a small excavator with a zero tail departure, equipped with the Yanmar engine. This apparatus has a complete set with a canopy and a full-fledged cab.

Its mass is 3580 kg in version with a canopy and 3720 kg from the cab. Machine dimensions: length - 4.72 meters, height 2.56 meters. The volume of fuel tank 45.5 liters tank, the volume of the hydraulic system is also 45.5 liters. If you compare this excavator with most of the other ministers, it is rather heavy and very powerful for its category, belonging to the so-called category. Mini Strong & Heavy excavators.

This machine is aggregated by a three-cylinder four-stroke diesel engine with direct injection and water-cooled. This power unit issues 28.4 hp. With a revolving maximum 2400 / minute. The achieved power allows you to move on this heavy machine at a construction site at a speed of up to 4.5 km / h. In the usual mode of movement, the technician maneuver at speeds up to 2.6 km / h.

Thanks zero departure The tail, the cabin of this mini excavator does not go beyond the housing, which allows it to be freely rotated in narrow places, without fear of damage to the cabin and walls or trees. Arrow excavators slightly shifted from the center, which allows it to dig in parallel caterpillars without changes in the width of the caterpillar base. In such a layout, it is easier to cuddle to the wall and dig a trench with minimal maneuvering. The running part of SK35SR-5 is not regulated (fixed base in the width of the caterpillars), which may in some cases make it difficult to pass into narrow places.

You can buy a mini excavator with soft rubber tracks, as well as with steel trackers having special rubber inserts. The second option is essentially a compromise solution between softness and durability.

The excavator cabin has all the necessary amenities, such as a comfortable seat, seat belt, backlight, robic hanger and an additional armrest. However, it certainly lacks stoves, air conditioning and radio.

As shown by the practice of using this machine, the technique is reliable, unpretentious, copes with a wide range of tasks in cramped conditions. In fact, its only disadvantage is stability problems that are compensated by the presence of counterweights. The price of a mini excavator makes think about the feasibility of acquiring it. Look at how much mini excavator costs, and perhaps you will arrange an alternative option - Rent a mini excavator. Or try to find such a device with mileage, but taking into account customs clearance, utilization collection, the valve can also bite. However, this dilemma is relevant for the majority of small excavators presented in our article.

Ultra-compact microexcavator kubota k008-3

Model K008-3 Ultra-Compact Weighs 997 kg. Its length is only 2.74 meters, height - 2.23 meters, width - 86 cm, which is generally a bit even for our compact family. This microxcavator is easy, agoned, but is quite powerful for small construction sites.

The width of the caterpillar base is regulated in the range from 72 to 86 cm. As already mentioned relative to other models of mini excavators of this class, the variable database of the propulsion is beneficial on maneuverability in doorways, between trees, in narrow corridors. You can also narrow off the excavator, making it in width less than the width of the caterpillar base, which will also add maneuverability to you.

A simple lever control system will allow you to easily switch from changing the width of the blade to the change of the width of the tracked base. The excavator is equipped with rubber tracks without the possibility of installing steel, which, on the one hand, together with its low mass makes it indispensable on the refined area, but on the other hand reduces the durability of the chassis (wear of rubber caterpillars).

Our mini-excavator is equipped with a three-cylinder diesel engine of 10 hp Of course, at first glance, such a minor power may seem insufficient to us, however, with such a small mass of the car, it is enough. The excavator has the ability to quickly access the radiator, the battery, fuel filter, coolant and air cleaner.

The K008-3 model has a two-speed transmission with traffic speeds: 2 and 4 km / h, respectively, each speed has a separate pedal. Technique comes without a cabin or canopy. There is a feeling that the Japanese on their excavators consider these options unnecessary, which we can observe both other excavators from the rising sun. As a security measure, there is a folding arc that does not have a roof. The dashboard itself has only a cooling fluid temperature indicator in the form of a warning lamp. Technique is certainly interesting, but will anyone want to buy a mini-excavator of too small and without special amenities for the operator when there are more powerful and productive competitors?

New Holland E18B CD

The small E18B New Holland excavator is a minimal cabin with a minimum crash. Comes in budget configuration with a canopy and in the top with the cab. The mass is about 1.8 tons, and what the model name is hinted transparently. Such a lot is unlikely to allow the delivery of a mini excavator to the object on the usual passenger trailer. Drive the excavator to the trailer on the dimensions you will be able, but if you will go so. Here you will obviously need a platform for the transport of a mini excavator or a passenger trailer auto transport. Dimensions from the cab: 235 cm - height and 365 cm - length.

Three-cylinder, four-stroke, diesel power unit Mitsubishi with direct injection issues 15 horse power At 2100 revolutions per minute. This distinguishes it from most fellow, preferring Yanmar engines. The hydraulic system accommodates 15 liters of oil and works under three pumps. The hydraulic motor installed on the reverse rotary device (crown) of the excavator allows 9 rpm. The angles of force turns relative to the cabin make up 80 degrees left and 45 degrees to the right.

A mini-excavator has a tracked propulsion (in the basic configuration it is an excavator on rubber caterpillars). As repeatedly mentioned above, rubber caterpillars have anti-vandal properties that preserve the lawn or a blocking. In mathematical expression, the pressure of the excavator to the surface is one kilogram per square centimeter. However, the strength of the rubber tracked propulsion in comparison with the steel, leaves much to be desired. Replacing the caterpillars - not such a big problem. The main difficulty is their high cost. However, you can always find chinese analogs via siper. The base velocity is 3.54 kilometers per hour, but there is a reduced transmission - 1.8 kilometers per hour.

Unfortunately, it is necessary to recognize that the New Holland E18B is a rather slow excavator (both at the speed and speed of the tower). In addition, the presence of an departure of the cabin, albeit the minimum, shyles it in movements. However, the compactness and relative ease of the model will allow you to perform a wide range of earthmoving tasks. Of the advantages, it is possible to note the variable tracked database along the width (which is not unique for this segment of mini-equipment) - the transverse envelope will vary from 133 cm to 99 cm, however, when you reduce this parameter, you lose stability.

Of course, the version with a canopy differs in comfort from the "Cabin Modification", but the version with the cab does not have an air conditioner, racks for robes, work light, radio and seat belt. However, the window is not such a problem, but the stove, which is certainly installed in the cabin, will play an important role in Russian expanses. In addition, instead of the E18B dashboard, it has external hydraulic and fuel manometers. Hinged additional equipment on rapid drives (BRS) is provided by the manufacturer.

Cheap Buy such a mini excavator will not work. The price of the mini-exercavator on the official website must say, bite. The market for this technique will rather small. Maintenance will be not cheap, however, as well as all the models listed in the article. However, this is compensated by the high reliability of our kids.

The excavator loader became perhaps the most popular earthy machine. Most often there are domestic machines based on universal tractors. IN last years Tractor builders (about the Minsk Plant can be said with confidence) began the release of modifications with an adapted cabin with a flat floor and a swivel chair.

Imported loader excavators have ceased to be rare, the segment of imported cars is growing very quickly, and the market has the feature that they choose either the most affordable Russian or Belarusian car, or a functionally saturated, comfortable and aesthetic foreign car with fully drive, Two-three steering modes, a two-dimensional loading bucket, telescopic handle. Additional amenities of the operator, the term "driver" or "mechanic" with a foreign car somehow does not fit out. If we spend money, then have a maximum from them. But practical considerations are not discarded. The working equipment controls are chosen, as a rule, lever with mechanical bond, and hydraulic pumps - gears: with them it is easier, faster and cheaper in repair.

Among the suppliers of imported technology determined the leaders. This is a British private JCB company, for a long time associated exclusively with loader excavators, quickly gaining the revolutions of New Holland, Caterpillar, which still cannot break out, Komatsu and Volvo, focused on the bulldozers, and the second on the articulated dump trucks. In addition to them, Terex, Case, Hydromec, Dressta are represented in Russia, but their sales affects do not provide.

JCB.Since 2004, radically updates and expand its most popular product line. The main models 1cx, 2cx, 3cx and 4cx in 2004 were added Mini CX. In 2005, the new generation of 3cx and 4cx engine with the engine of own production JCB 444 was displayed. A month before Bauma 2007, the pre-Bauma's "home" event was presented to a conceptually new MIDI CX loader.

Today the lineup has six basic models, The number of modifications will translate in two dozen. Thus, the coating model 3cx is supplied in six modifications that differ in the engine capacity, working equipment (single or two-shimmer loading bucket, with a telescopic handle of an excavator or without it), the wheel size on the front axle and steering control. With the same wheels on both axes and three-mode steering, 3CX Super modifications are supplied. Modifications of the 2cx family, very popular in their homeland, more diverse. There are options where instead of excavator equipment installed a compressor or a three-point jamming mechanism and VOM.

The main feature of the excavators-loaders 3cx and 4cx new generation, the supply of which to Russia began in the same 2005, is, of course, the JCB 444 engine (4 cylinders, the volume is 4.4 liters), which received the DIESELMAX resistant brand. The basis of the current line is the engines with the Bosch fuel system. COMMON RAIL.. Until the end of 2007, the issue continued last model With mechanical injection, which also meets the requirements of Stage 3A / Tier 3.

DIESELMAX engines develop the maximum torque at 1300 min -1, and the speed of rotation is limited to 2200 min -1. Large torque at low speed was one of the key criteria and reasons to host JCB for significant investments in the development and production. The torque gives the machine the power required to perform heavy operations on small revolutions, allows you to quickly respond to changing the load, reduces the duty cycle and reduces noise. Engine massive and hard. Cast iron cylinder block with boring cylinders in it is conjugate with a monolithic cast-iron support crankshaft. Block head is also monolithic and made of cast iron. The engine is aggregated with a new hydrotransformer with a red lock, designed for greater torque. In the hydraulic system, the pressure was raised by 10%, which not only increased the carrying capacity and the bulk force, but also reduced the dimensions and a mass of the hydraulic system.

The appearance also changed, and not only decorative. The composite hood is replaced by a solid, rising to the cabin. In the cockpit, externally the same as the model range of 2002, some internal improvements were made. So, the steering column has already become coincided in width with a hood. The front wheels and the arrow are clearly visible. The insides of the cabin, as always, JCB is distinguished by catchy design made in gray-black tones with inserts under aluminum. The choice of two options for working equipment management systems - lever and multifunction joysticks. Joysticks are mounted in armrests and turn along with the chair - you can work by turning the chair side.

The 2cx family, which includes six main modifications, differs from the "older" models with dimensional dimensions, lifting capacity and a sample cabin of 1997. Machines 2cx are compact and maneuverable - all wheels managed. All modifications 2cx are supplied with wheels of the same size on both axes. The smallest 1CX model has a common feature with a loader with an onboard rotation Robot - onboard rotation and hydraulic transmission, but 1CX engine in front, workplace It is raised and fairly spacious to install the swivel chair. The concept of onboard rotation gives significant advantages in maneuverability - turn on the spot. JCB has mounted excavator equipment for Robot loaders, but 1cx is designed precisely as a full excavator loader. Model 1cx is supplied with both open cabin and glazed.

New 2007 - MIDI CX Excavator Loader, as planning the developers, which occupied a technological niche between 1CX and 2CX. Exactly the same externally as 2cx and 3cx, the novelty includes many original technical solutions. First of all, it is a quick-consuming excavator hitch. Arrow, a frame with supports and control levers is made in the form of a single node, which operator may per lonerly remove and install other equipment in a few minutes, including an agricultural - the machine is equipped with the rear shaft of the power take-off and hydraulic connectors, the order will be installed on request.

The main loading bucket is also removable. MIDI CX is compatible with a wide range of hits manufactured for 2cx, mini-excavator model 803 and Robot loaders. The hydrostatic transmission with a full drive provides a stepless velocity set of up to 26 km / h. She also allowed to realize a tight layout of the compact machine. The MIDI CX is equipped with a 4-cylinder diesel engine with a capacity of 38 kW. A new excavator loader will be released in two versions - with ROPS / FOPS canopy and glazed cabin. For the first option, an excavator jacket with lever control is provided for the second - with joystick.

The first Eccavator-loader Mini CX Public saw on Bauma 2004. On Bauma 2007, Mini CX 4x4 Series II presented without unnecessary pump. The MINI movement leads a 3-cylinder diesel engine, a hydraulic transmission, in the model 2004, the drive to the rear wheels, the 2004 model, all-wheel drive, controlled wheels front. The JCB 8015 excavator is installed on MINI, so it has a whole range of equipment for mini-excavators. MINI CX is actually a toy and interest for russian market not yet.

What does JCB prepare? Two years at the "home" exhibitions show a conceptual model of an excavator "telescope" 4cx TM, and not the fact that in 2008 the concept will be embodied in serial model. The machine carries a two-section telescopic arrow, which is located along the axis of the machine over the hood. To compose the car in such a way, the engine was shone down, increased the wheelbase and applied the elongated arrow head board. Loader loader - 2.5 tons, lifting height - 5.2 m. Rear from the machine - "ordinary" excavator equipment.

Persecution of the product basket, arranged by CNH (Case-New Holland), gives results. Efforts are not blurred in four partially competing with each other brands, and concentrated on one - NEW HOLLAND. As in the case of mini-loaders, where New Holland broke out on the second after the Bobcat position among importers and heads a group of catching up, in the segment of imported forklifts, it captured second place after JCB.

Although NEW HOLLAND is a US brand, but CNH is belonging to the Italian spruit Fiat Group, the loader excavators produces the plant in the Italian town of Imola, the development is also Italian, especially since today's line is directly from the Fiat-kobelco line. That is, the Americans took only a signboard to maintain the sales of Italian technology in North America.

The current line of the New Holland LB90.B, LB95.B, LB110.B and LB115. B is actually repainted FIAT-Kobelco. The first three models are made on one platform and differ in the engine capacity 71 and 82 kW, size and characteristics of excavator equipment. Dimensions and capabilities of the "senior" model LB115.B are impressive. She has the same size wheel on both axes of the wheel and trust steering.

New Holland Excavator Loader can be found from afar on the characteristic form of an excavator boom and a straight loader. Hexagon, glassy on the perimeter with flat tinted windows cabin looks modern and stylish, and in general the look of the excavator-loader is harmonious and pleases the eye. However, the composite hood is clearly outdated. The interior of the cabin is a good, but this functionality only wins - nothing distracts, the eye does not cling to bright trifles. Cabin finished with gray solid plastic, quality of manufacture and assembly of decoration details on high level. Managing work equipment lever. The joysticks of control excavator with a servo are equipped by order. Joysticks are installed on high columns and are not connected to the chair.

In the basic configuration, three "younger" models are equipped with synchronized mechanical box Transmissions (KP) PowerShuttle 4x4 (four transmissions forward and four back). The clutch function performs a button on the gear lever. For the "senior" LB115. B - standard semi-automatic CP PowerShift 4x2 (four forward and two backwards) with a submit switch. The same KP is offered as an option for "younger" models.

On Bauma 2007, New Holland introduced upgraded models B110 and B115, performed on the same platforms. Their main differences are the engine CNH 445TA / EGH Stage 3A / Tier 3 with a capacity of 82 kW at 2200 min -1 with a battery injection system, turbocharging and intermediate charge air cooling. Several processed form of anterior counterweight in order to improve air access to the engine compartment. Composite hood design has been preserved. NEW HOLLAND sign on the windshield is designed, it is likely to improve the review. The design of the instrumental panels was refreshing, it became more catchy. Since the Common Rail engine controls the electronics, logical to replacing the speed adjustment lever with a rotating regulator.

Backhoe loader Caterpillar. Easy to learn from the rear by characteristic curved arrow of the excavator. Until 2006, the Caterpillar loader rayer was not called complete - there were no powerful models with the wheels of the same size on both axes. The D series was performed on the same platform, and the models differed from each other with a complete set. Reviews about her were very good. In particular, they said that in the frosty winter, the Winter, the CAT loader, as opposed to competitors, was started.

In January 2006, Caterpillar brought to the market a new series E. In the lineup was six basic models against four, added "senior" models 434e and 444e, which received the rear axle with controlled wheels and wheels of the same size on both axes. "The younger" models 422e, 428e, 432e and 442e supply with wheels of different sizes, in standard equipment Control wheels front. Inheritance from Series D, the Caterpillar 3054c engine with turbocharging (for 422E - atmospheric, turbochards option). Compared to the series D, the hydraulic guide and geometry of the lever mechanisms of the loader, due to which increased the discontinuous force by 10%. Radically changed the design of the telescopic handle of the excavator included in the extended complete set. If machines D series, the telescopable section was inside the handle housing, then the series E is on the contrary - external case is put forward.

Models 422e and 428E in the basic configuration equipped with the mechanical KP PowerShuttle 4x4 and the lever controls of the excavator, model 432e and 442e - KP PowerShuttle and joysticks, commissioned by the semi-automatic CP AUTO-SHIFT 5x3. Joysticks and CP AUTO-SHIFT are included in basic complete set "Senior" models 434e and 444e. The joysticks are installed on the speakers separately from the chair - the solution becomes standard.

If you remember that the D Points of the D Points of the D Points are focused on the left side and are available through the hip folding half, and for more detailed access to the engine compartment, they must be armed with a wrench, then this situation has been somewhat somewhere. The hood cover rises entirely from the cab. The design of the cab is refreshed both outside and from the inside. The geometry of the cabin changed, the flat glasses were replaced bent, rear glass It became whole. Several modified the design of the steering column and the toolbar on the right side.

Line of excavators-loaders Komatsu. Includes five models - three models with front controlled wheels WB91R-5, WB93R-5, WB97R-5 and two (WB93S-5 and WB97S-5) with all controlled wheels. The Russian office is trying to emphasize the attention of buyers on the three most functional saturated models - WB93R-5, WB93S-5 and WB97S-5. They belong to the fifth generation, the release of which has begun in 2006 at the Komatsu Utility Europe factory in the town of Este (Italy).

The characteristic feature of this generation is the Komatsu engine on which the Iveco label can be found. Engines are not taken from another hemisphere, they are assembled here in Italy. Another interesting feature is useful for the cold climate - the preheater feeding from external source 220 V.

The appearance of the fifth generation has changed much, acquired modern streamlined forms, the cabin was equipped with large bent glasses that do not obstruct the review. The shape of the boom of the excavator is changed: it has become curved, and the bracket of fastening of the hydraulic cylinders moved to the middle.

Three models of interest to the characteristics are pretty close. The "younger" model WB93R-5 is equipped with wheels of different sizes on the front and rear axles, a 4-speed mechanical CP PowerShuttle. WB93S-5 has all four wheel 24-inch wheels, installed PowerShuttle KP, on WB97S-5 - 28-inch wheels and semi-automatic CP PowerShift. Front-wheel drive turns on both manually and automatically. When the speed set, the drive turns off automatically, when braking it turns on again. On the WB93S-5 and WB97S-5 trink steering with all the wheels, on the "younger" model WB93R-5 - only in front. To switch the steering modes, you need to press two buttons at the same time on the control panel - this is protection against accidental switching.

Package of cabins differs mainly by the controls of the excavator. WB93R-5 and WB93S-5 are equipped with lever mechanisms, WB97S-5 - joysticks. The joysticks are installed on the speakers separately from the chair. Loader control lever is replaced with a multifunctional, aesthetically more winning joystick. The design of the instrumental panels and the location of some devices and switches so that access to them becomes easier.

Closes the top five leaders Volvo se. The company has long been engaged in the construction of tractor excavators on the basis of tractors and front loaders with an articulated frame, and since 1965, from the gate of the plant in Eskilstuna, not one generation of such cars was published. By the Third Millennium, Volvo began to prepare a new generation of loader excavators, going along the path that was laid JCB and Fermec. That is, an excavator-loader must have its own, intended only for it, the base machine, and not putting tractor or converted front loader. The development started in fact from scratch took about four years, and in the spring of 2002 the company presented the first models of the modern line LB70 and LB71. Production deployed at Volvo factory in Wroclaw, Poland. In 2004, the line was expanded by LB60 and LB61 models, and in 2007 there were modifications of LB71 Plus and LB61 Plus. The LB60 and LB70 models differ from the remaining excavator equipment with an unlocked digging axis and folding supports.

The total 4-cylinder 4-liter Diesel Volvo D4D is aggregated with a synchronized mechanical CP PowerShuttle 4x4. The engine power varies from the model to the model of increasing. For LB61 Plus, LB71 and LB71 Plus offer advanced configurations with semi-automatic CP PowerShift 4x4, excavator control joysticks and a two-dimensional loading bucket. For machines equipped with the mechanisms of rapid shift of excavator and loading equipment, a hitch is available similar to the sizes of excavators and loaders.

The appearance of the excavator-loader is made in the spirit of modern trends, the cabin is spacious and comfortable, but the interior looks old-fashioned today, especially the wide front panel.

For users of Volvo equipment: Oils under the Volvo brand produces ExxonMobil. Own mobil oils Have a volvo tolerance.

The extraction of coal, manganese, ores containing metals, other minerals is associated with the movement of large volumes of rocks, drill and explosive work, and is produced all year round. For this heavy, in all senses, an appropriate technique is necessary. An opening of deposits and subsequent recess of minerals with subsequent loading on a special car or railway transport is engaged in a specialized type of excavators - career.

As it is clear from the name, career excavators are used, extracting minerals in open developments, performing overnight work. These machines are designed taking into account operation in a wide variety, including hard, climatic conditions, with different types Soils are intended for intensive use. Without such excavators, do not do on mining developments in the coal industry, on the extraction of building rocks, in color and ferrous metallurgy.

Power, adaptability to long-term, including round-the-clock, work, high efficiency, the possibility of using electricity for the functioning of such equipment is a distinctive feature of these earthmoving mechanisms.

Device

The modern career excavator consists of a number of functionally complete structural nodes, allowing to efficiently maintain and repair them. The following functional parts can be given:

• Rama with caterpillars.
• Two-legged stand.
• Lower frame.
• Rotary platform.
• Body.
• Arrow with handle.
• Ladle.

Much attention is paid to the working place of the operator. Cabins are installed good overview, vibro- and soundproofed, with heating and air conditioning systems, ergonomic controls, control systems for the efficiency of the excavator.

Classification

Career excavators can be classified with such signs:

• Type of chassis: Crawler, walking.
• Principle of operation: cyclic action (single-loving) and continuous operation (rotary).
• The type of engine used: diesel, electrical, single-engine or multi-motor.
• Drive type: hydraulic, hydromechanical, mechanical, electric, etc.

Adopted when choosing to be guided by the principle that optimally - download dumper For 4-6 working cycles of the excavator used.

Crawler

This type of excavators are divided into several types by the number of caterpillars installed on the platform: two-, four- and eight-dimensional. As working devices, reverse or straight buckets with a capacity of up to 50 m3 and more are used.

Rotor

These excavators may be tracked or walking. At the end of the boom is a rotary rotary wheel on which the buckets are fixed. The volume of each of them can reach 6 m3. The arrow itself can be both retractable and non-sensitive. Rotary and dump arrows can rise and descend. Range of action when developing breeds up to 50 m and up to 25 m in depth.

Rotary career excavator

In motion, such an excavator is driven by an electric motor.

Hydraulic

This is one of the most common types of excavation techniques used in the extraction of ores, minerals in careers. These machines are used for loading breeds in transport.

Excavators of this type are equipped with rushes of direct and reverse types. Diesel engines or electric motors are installed.

Hydraulic career excavator

Walking

This type of excavators can often be found in overnight work, in most cases they are equipped with draglin. His name - walking - received from the method of movement. In the working position, the excavator comes into contact with the soil with the help of a support frame. When there is a need for a location change, the support "skis" are put forward, the excavator is raised on the hydraulic rods, moves to a certain distance (makes "step") and again falls on the frame.

Walking career excavator

Given the high weight of such mechanisms to hundreds and thousands of tons, this design allows you to achieve a low pressure pressure on the ground, which would be impracticable when using a tracked propeller. The length of the boom can reach 100 m, and the volume of the bucket - exceed 100 m3.

Popular models

Release of career equipment is engaged in several well-known foreign manufacturers. Russia also produces similar cars. Among the leaders in the manufacture of equipment for work in open fields are Hitachi and Caterpillar. Here brief characteristics Modern popular models of these brands.

Hitachi

The company Hitachi in terms of sales of career excavators is the leader in the global market. IN model row - Two-tech hydraulic machines with bucket volumes from 1.15 to 43 m3. Some model characteristics are shown in the table.

Table continuation

On the model EX3600-6, EX5500-6 and EX8000-6, in addition to diesel, electric motors Hitachi TFOA-KK can be installed.

Traditionally, the technique of this brand is characterized by the use of economical and reliable engines, an effective hydraulic system. Much attention is paid to the reliability and durability of the rotary assembly. Help persists in the widest range of external temperatures - and at +40? C, and at -50? P.

Caterpillar.

For career works, Caterpillar offers hydraulic excavators different power, as well as cable cars, in which an electric motor is applied.

Hydraulic

We give the characteristics of some models.

Electrical motors can be installed on the 60xx models instead of diesel.

Cable electrical

Despite the hydraulic excavators are increasingly used when working in careers, cable models continue to be released, allowing them to be effectively used on overcurrent work and mining ore.

Cable Electric Career Excavator Cat 7295

Due to the electrical drive and lathes of large capacity, they allow you to move significant amounts of soils, rocks with low cost.

The table lists the main characteristics of some models:

Effective deposit development directly depends on the quality and effectiveness of the technique used.

A large selection of career excavators allows you to choose the desired model, considering the type of rocks with which you will have to work using vehicles, operating conditions and other factors.

On the video career dump truck Hitachi:

Small dimensions, increased patency And manevrost make a mini excavator of a literally universal machine, whose services are needed in all spheres of activity - construction, agricultural, communal, etc. In general, this is a reduced analogue of tracked dimensional loaders, only in this case the weight of the car will vary within 0.5- 1.5 tons

Features of technology

All models of small excavators on the caterpillars or wheelbase are designed to ensure that the operation of large loaders can be performed in cramped conditions. In addition, this technique is convenient to use in combination with full-sized machines. Crawler excavator Perfect for the tasks of different areas of activity:

• building housing quarters;
• creating road strips;
• laying a new or dismantling of an old water supply system;
• arrangement of garden plot, creating landscape design in park areas;
• locking and transplanting shrubs, small trees.

This technique is successfully applied at production areas, in closed shops, hangars, industrial divisions. All listed functions of the special equipment can only be performed due to the preservation of the technical characteristics of the standard excavator on wheels or a caterpillar, but with reduced dimensions.

Komatsu PC35MR-3

Mini Special Equipment Komatsu has an integral control system for simplified management of all mechanical components.

Komatsu PC35MR-3

Specifications:

The increase in the number of owners of land plots caused demand for various mechanisms that can work on a relatively small space. Use ordinary, overall machines is quite difficult, and in some cases it is inappropriate. This is caused not only high cost Services (or lease of equipment), but also a number of other reasons - the impossibility of entry to the place of work without additional training of the track, restriction in maneuverability, risk of damage to plantations and the like.

The industry has established the release of many images of the "mini" category, mainly intended for the private sector, although they are no less attractive for urban services, small farms or specialized small business structures. But if such aggregates, like a cultivator, a snow blower of small sizes is already not new for anyone, then about mini excavators domestic production Heard few. But if you deal with their functionality and multiplicity in use, they will cause genuine interest among most "private traders".

Application (basic options)

Mini-excavators - versatile cars, but readers, as a rule, are more concerned about the issues of domestic use of technology. On this and make an emphasis.

Excavation. The types of work with which you have to face the owner of the hectare, most different - preparation of a pit or trench for the foundation (for septic, well, gaskets of engineering communications), holes under the poles (supports) and so on.

Drilling. For example, when arranged with a fence of a fluid from a well.

Alignment of the site. If you got a waste, then this will probably have to do. Difficult relief, and therefore, the perspective to shut down the step landscape attracts little. And for lovers, such exotic mini-excavator will also be a good helper.

Moving cargo. For example, the delivery of a solution from concrete mixer to formwork, export from the site of construction waste or the carved soil - the situation in everyday life when manual labor is inffective, there are quite often.

Dismantling (full or partial) small buildings. This necessity often occurs if the construction is intended for demolition or prepares its reconstruction (alteration) when buying already an obligrant land of land, when new owners do not suit the former layout.

A brief overview of Russian mini excavators

Consider all models presented on the market does not make sense. Causes two.

Firstly , domestic producersUnfortunately, not so much (the consequence of the post-transfers and the collapse of the industry). As for the class "mini", it is even more difficult here. Therefore, almost everything that is on sale - imports, units from the neighbor (Belarus) and far abroad (Germany, China and a number of other countries).

Secondly, even one particular model is always available in various configurations, which somewhat changes the functionality of the base sample and expands the possibilities for its use.

Therefore, as an example, consider the mass producer of this technique in Russia. This is not an advertisement, and according to the author, today it is the only optimal version of a small-sized excavator, which can be effectively used in the private sector, especially since its price is quite accessible, which cannot be said about foreign models. If you, dear reader, these models will seriously interest, then on the manufacturer's website, find more detailed and expanded information will not be difficult.

"Geogid"

Manufacturer - Machine-building Holding "Partner" (Chelyabinsk).

Model "15G"

In fact, this is not a self-devaluing machine, but a trailer. This option is especially attractive for the owners of small sites (country house, cottage and so on).

The engine (gasoline) on 15 "horses" allows you to dig a trench (pitched) to a depth of 1.5 and lift cargo by 1.8 (m). Linear parameters of the machine - 284 x 125.5 x 238 (cm), weight - 0.75 tons. The booster turns to the left-right to 450.

Basic price - from 275,000 rubles.

Model "20G"

Available in 3-grades (basic, premium, standard). A significant difference lies in the level of control and options for additional snap. Gasoline engine; As can be seen from the designation, on 20 "horses". Machine weight - from 2.2 to 2, 35 tons. Consequently, the impact on the soil is no more than from the usual "car".

The dimensions also comply with the definition of "mini" - 345 x 155 x 353 cm (rounded values). The volume of the bucket is from 0.4 to 0.5 m3, width - 30 cm. Such an excavator can be equipped with a depth of 3 m and lift the cargo by 2.5 - 3.3 m (depending on the modification).

"Premium"

All excavators provide an additional / equipment installation (dump, for example), for which the corresponding hydraulics elements are mounted. Connection is performed within a few minutes.

Price - from 545,000 rubles.

The "20D" modification differs only by the engine. It is more powerful, by 27 hp Accordingly, the price is higher - from 640,000 rubles.

Model "60 DC - P"

Much more powerful; Engine at 60 hp The dimensions and weight are somewhat more - 360 x 126 x 350 and 2.4 tons. The height of the bucket is 330 cm.

Price - from 1,055,000 rubles.

The list is rather modest, but domestic mini-excavators fully provide excavation in the private sector. And if you think about, our cars are preferable. Justifications to this statement are several.

• First, quite affordable prices.
• Secondly, reliability. Russian aggregates are designed to meet all the features of our climate, adapted to local conditions. As for imported models, they are more "capricious".
• Thirdly, problems with zap / part and their delivery, as a rule, does not exist.

Information is enough to understand the feasibility of the purchase and decide on optimal option mini excavator.
