Market overview of import wheeled excavators. Russian hinged and trailed mini excavators Landformer

The excavator loader became perhaps the most popular earthy machine. Most often found domestic machines based on universal tractors. In recent 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 fuel system Bosch. 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.

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 model Row 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.

Family 2cx, including six main modifications, is different from the "senior" models overall dimensions, lifting capacity and cabin sample 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 in motor 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 new series E. The line 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. "Younger" models 422e, 428e, 432e and 442e supply with wheels different size, In the standard configuration, controlled 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 the basic set of "older" 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, useful for cold climate - preheatereating 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 basic machine for it, and not a disappearance tractor or a 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.

Any construction, and even more so the laying of the pipeline is unthinkable without the use of the excavator. Since the day, earthworks began to be made, the construction thought worked in the direction of increasing the productivity of this process.

More Leonardo to Vinci made the first drawings of the Draghunca Draghling. In 1776, a steam drive was applied, created with the participation of James Watt. In 1809, the first floating excavator was built in St. Petersburg, and in 1812 the idea was implemented at the Izhora factory, it was the first multiflower excavator. In the second half of the 20th century, new engineering technologies and equipment (hydraulic engine, etc.) were actively introduced.

The production of excavators in our country begins in the 1930s, among the first there was a factory in Ivanovo, working under the brand of Kranceks. Now in Russia there are several dozen enterprises collecting excavators of various purposes.

The most common excavators are engaged in digging soil and loading bulk materials. To accommodate such excavators to the highest number of tasks, the possibility of shift hinged equipment. So, a modern excavator, with the help of additional equipment can also be used for loosening of particularly solid soils and to dismantle the structures of different strength. In order to ensure maneuverability and multifunctionality, single-sized excavators are used, but in conditions when you need the greatest productivity, multi-loving excavators are used. As a rule, they are designed for stationary conditions, for example, to work in careers.

Multifungal excavator

Depending on the working conditions, different types of running part are used. Traditional tracked and car chassis in special conditions replace floating, rail and walking, and also use combination different types chassis.

Excavator on a walking chassis

In addition to widespread excavators models in separate areas of industry, there is a need to create specific machines. For example, underground excavators used for underground mining of minerals with high density of rocks or tunnels used for loading blemied rocks.

Underground excavator

Permanent criteria for improving excavators is the reduction of energy consumption on one side, and on the other hand, an increase in power and performance. There is also a search for opportunities to create more versatile machines.

Russian engineering today has considerable experience in the construction of earthmoving machines. Leading enterprises try to create samples competitive in the global market. Often these tasks are solved by completing imported systems, which ultimately leads to the rise in the cost of operation of equipment, but also implemented and completely domestic modern engineering solutions. For example, a trainer company since 2006 produces an EK 450 FS model with a bucket of a straight shovel type.

Bucket straight shovel

In comparison with the usual bucket, the "straight shovel" allows the excavator to produce work, which is usually performed in three different units. construction machinery - "classic" excavator, front loader and, under certain conditions, a bulldozer.

Currently, due to a possible ban on the import of modern construction equipment, many Russian enterprises took the course to issue domestic productsnot inferior in its characteristics of foreign production. Time will tell whether our manufacturers are ready for import substitution, whether they are ready to more actively conquer the internal and export markets, in the conditions of the low course of the ruble - these are questions for which we will know the answers in the near future, because it's no secret that I would like to buy the technique of Russian manufacturers , just being confident that this is the best choice.

The speed of movement of the excavator on a wheeling can reach 35 km / h (and if it is attached to the truck, even more), which is about 8 times higher than the speed of the tracked machine. The wheel trains do not apply almost no damage to the road surface. Therefore, these cars are trying to use in those places where the tracked car is ordered, for example, within the city.

In this sense, any movement of the caterpillar excavator on the roadway leads to the formation of dents and cracks, and work on the territory of the park or recreation area turns this zone into the mash, while low pressure on the ground pneumatic tires Allows the wheelchair to move freely on soft or paved surfaces without prejudice to the coating.

Wheel excavators Builders prefer to acquire or lease, of course, provided that the maximum high permeability and lifting capacity will not need, but it will be necessary enough high power Special machinery. At the same time, "Kolesniks" capable of working on the soils to the IV category are inclusive, are often used on very serious excavator work - when the soil is drawn up and obtaining the desired slope when creating a basis for the future construction site or during the preparation of a pit for laying the foundation. For such work, except power requires accuracy when moving the soil, very good handling and circular visibility - all these qualities, modern full-turn wheeled excavators just possess. But, in addition, they are very convenient when working in cramped conditions and are generally universal, as they can be used to remove asphalt, cleaning cuvettes, digging trenches for laying communications, moving the construction trash, planning under the base and clearing platforms by bulldozer, use in quality of the lifting mechanism. These machines, in addition to the obligatory bucket ("reverse shovel") and a bulldozer dump, are equipped with a wide variety of tools: a "direct shovel" bucket, a hydraulic hammer, hydronic, grab, a ripper, etc. With the help of an excavator, you can even drill well under the poles.

Manufacturers of wheeled excavators

Wheel excavators russian production Basically represented by Tver Twex and Eksmash plants. Tverskaya Excavator (TVECs) is included in the company "RM-Tereks" (is a joint venture of the Russian Holding "Russian cars" and the global manufacturer Terex Corporation). Here release wheel Excavators TVEX Series The operational mass of 14.4 tons and 17.6 tons and the EC operational mass of 14.9, 18.0 and 20.2 tons. TVEX cars - the new product of the company with a comfortable modern cabin, the engine of the Minsk motor factory D-245 with a capacity of 122 liters. from. (Tier II), Zahnradfabrik bridges and transmission, Bosch-Rexroth hydraulic equipment components, Poclain turning mechanism.

Plant "ExMash" produces two models of pneumatic full-time excavators with an operational mass of 13.2 and 16.2 tons. The machines are equipped with an economical turbocharged engine Deutz with a capacity of 91 hp, drive bridges and gearbox production of Germany, hydraulics produced by Bosch Rexroth. The hydraulic system, made according to the LUDV scheme of the Bosch Rexroth company, provides an unlimited number of combinations in the working cycle. The distribution of the stream of the main LS pump between the actuating mechanisms occurs with the priority of the rotary mechanism to reduce the time of the working cycle. The feature of the excavators is not analogue in the world, a capotic system with a horizontal counterweight. In 2013, the plant increased the warranty for excavators to two years or 1500 m / h, and the maintenance interval rose to 500 m / h.

Significant share of imports to Russia wheel excavators Now make up hyundai cars (Operational mass of 5.5 - 20.5 tons) - more than 30%, Doosan (5.6-20.8 tons) - 20% and Caterpillar (14.0 - 22.5 T) - more than 10%. Also in our market are well represented wheel excavators CASE (10.0 - 22.7 tons), Hitachi (16.5 - 21.1 tons), JCB (12.7 - 21.4 T), Komatsu (14.2 - 22.3 tons), Liebherr ( 18 - 21 tons), Volvo (12.8 - 20.1 tons). The company "RM-Tereks" offers compact TEREX wheel excavators of the TW series of 6.8-11.0 tons.

Constructive features of wheeled excavators

Single-line hydraulic excavators have a long-standing design, which is nevertheless constantly being improved. The hydraulic system that performs the functions of the power actuator and the management of the working bodies, in modern excavators is equipped with an adjustable performance depending on the load. This reduces the duration of the working cycles, increases the effort on the bucket and handle.

So, U. hyundai excavators The CAPO automated system is used, which controls the hydraulic system and adjusts its parameters to obtain maximum performance parameters. The JCB excavators are standardly installed an improved intelligent AMS control system - it controls all the basic functions of the machine to ensure maximum performance and fuel efficiency. Doosan excavators are also equipped with a new hydraulic system controlled with the engine with the engine electronic control E-EPOS to obtain optimal power and fuel economy. Komatsu excavators are equipped with an exclusive Hydraumind on-board system, which makes it easy to perform all operations, providing elevated performance features cars. The Liebherr LSC excavators hydraulic system ensures the coordinated operation of the engine and hydraulics, allowing simultaneously saving fuel and rationally use the pressure of 350 bar.

The excavators are set pretty powerful four or more often six-cylinder diesel engines from liquid cooling, turbocharged, direct fuel injection with the use of a COMMON Rail injection battery system or a system of individual injection pump with high injection pressure - up to 2000 bar. Such diesel engines have a high torque at low crankshaft revolutions, which is just required for efficient operation of the excavator. In addition, modern motors correspond to the strict provisions of the toxicity of exhaust gases - American EPA Tier 3 and European EU Stage IIIA. For example, for engines with a capacity of 75 to 130 kW emissions with exhaust gases of carbon oxides according to Stage IIIa, should not exceed 5 g / (kWh), nitrogen oxides and hydrocarbons - 4 g / (kWh), and solid particles, then There are soot, - 0.3 g / (kWh). These standards correspond, for example, all Caterpillar turbodiesels, made using ACERT technology, all Volvo engines created using the technology of organizing the combustion process V-ACT, all new KOMATSU engines with Ecot3 designation, Liebherr engines of own production D 934 S.

Transmission is installed directly to the rear axle for maximum road Suit, as well as to protect it with a powerful bridge from those flying from under the wheels of stones. Front axle Perform swinging, with a swing angle to 10 °, while the automatic locking of the cylinder of the bridge swing is applied, or it is performed from the operator's cab. Transmission by modern machines Fully supplied automatic box Transmissions switched under load. The standard uses permanent drive on all wheels. On modern machines, bridges are equipped with non-servant disk brakes with hydraulic drive.

The drive mechanism of the platform rotation is carried out by a separate adjustable piston hydraulic pump and an unregulated piston hydraulic motor. A separate pump means that the hydraulic drive circuit is closed, that is, no power reduction occurs when other hydraulic devices are connected. Arm beams and handles have a box cross section. A number of different arrows and several arms of different length are proposed. Arrows can be both monoblock and two-section. The boom hydraulic cylinders, handles and bucket to mitigate shocks are equipped with damper devices (hydraulic plates). The device is used everywhere to quickly shift attachments so that it is possible to install hydraulic hammer instead of the bucket instead of the bucket, etc. In this case, the machine is equipped with a separate hydraulic circuit.

To improve stability and reduce the load on the support surface on both excavators bridges, dual wheels are installed. For greater stability during the operation of the excavator, the role of support, as is known, performs a bulldozer dump, and on the opposite side of the car, independent remote supports (outriggers) are lowered with swivel shoes. Dumps and remote supports are now interchangeable, so that the outriggers can easily be installed in front and behind.

The cabin has a thick-walled tubular frame. Fastening to the frame - through rubber supports for breeding vibrations. Multilayer shockproof glasses are attached in the openings of the cab panel without frames, which increases the overview. Windshield is performed divided. Steps and platforms are covered with perforated steel plates so that the operator does not slip. In addition, in the zone of the heads of the bolts, they are recessed so that the operator does not stumble about them. Of course, the cabin must meet the requirements of the ROPS system. At the request of the customer, some manufacturers produce machines with a hydraulically raised cab - it is necessary to increase the survey of the operator, for example, when unloading high wagons.

Operator seat is equipped pneumatic suspensionwhich automatically adjusts to the mass of the operator. Adjusts the settings of the seat, armrest, consoles. The right console establishes frequently used arrow controls, handle and buckets, on the left - control bodies and remote consoles. To enlarge free space On the floor, a two-way pedal of control of the move and contours of the work equipment is used. The high-pressure working circuit control pedal is fixed in a non-working position. For ease of informing an operator about the operation of the machine, a color monitor or a multifunctional display with the menu system and the programmable shortcut keys of some of the most required functions are applied. Under the order is installed by the rear view camera. In the cockpit is maintained overpressure. A climate installation is used, which includes the heater and air conditioning. The distribution of warm air in the cockpit occurs with the blowing of all window openings. Cabin noise insulation is at a high level, so you can install a good music center. Noise level in the cabin modern car does not exceed 72 dB (a). Reducing the level of noise and vibration is ensured largely due to the flexible fixing of the cabin to the frame. By the way, for the implementation of Directive 2000/14 / EC, designers work on a decrease in the outdoor level of noise, reducing it to 98-100 dB (a).

Many firms to track the work of the technique to save fuel and reduce expenditures for operation began to actively use navigation systems. Hyundai excavators, for example, a Hi-Mate remote control system is installed, which functions using GPS navigation. Volvo as standard equipment CareTrack branded telemetry is applied - this equipment is included in standard complete set Most new large-sized models of this company. Liebherr serially applies Lidat on machines. The machine is equipped with a built-in GPS, modem and antenna receiver. With this equipment, the data comes from the machine to the central database through the GPRS / GSM mobile network or satellite communications. In addition, the GPS network serves to determine the accurate location of the machine. The CareTrack connected system transmits the operational reports of the machine, about the daily operation in machine commodities, about the timing maintenance, On fuel consumption. By the way, fuel consumption is determined by again the branded "Volvovsky" on-board diagnostic computer MATRIS, which is able to provide a detailed analysis of the entire history of the machine.

Modern excavators have a high ability to reuterization, which is very important for environmental protection. Volvo machines it reaches a record 95%. This company is generally famous for the ecology - paintwork coverage of external parts in Volvo excavators does not contain lead.

A very timely decision in the struggle for the environment was accepted at Caterpillar, starting to apply biodegradable hydraulic oil, which, unlike mineral oils, is completely decomposed by microorganisms in soil and water.

In 2012, Caterpillar presented an updated line of wheel excavators of the 300th series, created specifically for the CIS market.

The flagship of the updated series was the wheel excavator Cat M318D. In the basic configuration, in addition to traditional options, such as a hydraulic hammer and a device for quickly changing attachments, CAT M318D may have a unique SMARTBoom system. It allows when using a hydraulic woman to translate the boom and handle into the "floating" position in order to reduce the load on the hydraulic and equipment.

All excavators of the updated line are equipped with default by the Caterpillar Product Link system that remotely informs the client about the basic parameters of the excavator.

Separately, I would like to say about the automatic retainer of the transport position of the turning platform. With the help of the pedal in the cockpit, the operator fixes the platform and can start moving without leaving the cab.

Among the changes in the design can also be noted:

• increased area of \u200b\u200bdump-support for greater stability of the car in cramped urban environments, when there is no possibility to take advantage of remote supports (legs);
• the new monitor and the control panel, on which all switches are grouped under the right hand of the operator, which greatly simplifies work;
• new pressure, temperature and new drainage valve in the hydraulic tank for greater reliability of the machine.

But the versatility of the wheeled vehicles, inferior to this indicator only to loader excavators, has its limits. Wheel excavators unambiguously leave the tracked machines on unstable soils. In addition, the presence of a wheel chassis implies serious load limits on the axis than, in fact, the fact that there is no "kolester" with a production mass of more than 30 tons.

Nevertheless, universality is often much more valuable quality than power. It has proven excavators-forkliers that are now more in demand. Statistics of the Russian market engineering market shows that the loader excavators enjoy the greatest demand: for the first half of 2013. They are sold in Russia about 4,000 units, while wheeled excavators are just over 1000 units, and medium hydraulic (tracked) excavators Operational mass from 20 to 33 tons - about 2000 units.

It seems that building and road organizations, reflecting on the dilemma: to purchase a new wheel excavator or an excavator loader, which in some cases will save on the front loader, choose the second. Although the builders, of course, understand that, acquiring a more universal excavator loader, they receive a weak and moreover an incomplete excavator, which is not able to cope with any large-scale task, when needed, for example, transfer a large ground for very a short time. The fact is that the loader excavators and wheel excavators are in different weight categories: the first occupy a niche to 12 tons, the second - up to 27 tons.

The reason for the popularity of excess loaders More is associated with a general tendency of mechanization growth in construction sites, when developers with the help of this technique begin to actively deprive the operation of unqualified workers with a shovel. Wheel excavators on this wave does not become much more - heavy equipment and unskilled labor does not intersect if, of course, not counting the distant times of the first five years. However, some increase in competition in the market of earthmoving vehicles in itself is not bad - all this leads to the emergence of more advanced technology.

Hello everyone. I will begin the story that it is good that I have a son and so now I have several radio-controlled toys that purchased allegedly)). The review we will talk about an excavator from a decent brand with an indecent name - Huina. We look, we test, feed the cat, brew tea, we carry slippers, make conclusions. Details under the cut ...

Brand himself Huina. It is quite popular with its quality for the reasonable price of radio-controlled toy technology. Oh, where are my 7 years? In my childhood, I would give a finger for such a toy. Although, in fact, no matter how many years. I could not go away a few evenings now, even when the review was ready and there was nothing to add. Even in a habit of habit - when the city falls asleep ... the excavator of Mikhalych wakes up. Though go discharge))

Packaging:

When I got a box with a cassette tape recorder "Spring" in the mail, I didn't even believe my package. In the photo in the store, the excavator seems quite a toy. In reality, it seems that this is a real working technique for minor work, for example in hard-to-reach places. It is immediately felt that playing you can not just show the imitation of construction actions, but also to perform small orders, for example, bring the gearboxes from the next room) or a bottle of beer until the wife sees ...

The weight of the most construction machine itself is an impressive - 1651g (packaging weighs - 2400gr)

In addition to the machine itself, there is USB charger And the battery in the excavator battery compartment. In the battery panel did not turn out, but this is a usual thing.

Appearance:

There is no complaints of claims, even if you find fault. All items are made high quality and do not crush when pressing. Painting is excellent, untreated seats did not notice. And the design pleased - very similar to the original.

Forceps:

The company Hyne (yes, this is exactly the case) there are many radio-controlled construction equipment, but they themselves have 3 types: with standard bucket, tongs (survey hero) and with a jackhammer. Son decided (aha, aha) to choose exactly a model with tongs, because At home, it is interesting to grab something and pinch than dig a hole somewhere in the middle of the room in the parquet. The Chinese argue that this model It is characterized by both the pipelayer, but in reality, the pipe layers are completely different - with side supports and pipes are grabbed by cables and hook. With the same forceps in reality, it is unrealistic to grasp the pipes and holding the balance, then stacked them. As a result, the paradox: this model, as a real technique, is useless, as a toy is more interesting and more functional. Moreover, the tongs are iron and shrink pretty much.

On the photo, without problems grasped and raised 300gram lavas. By the way, and the bottle of water in 0.5 can be brought. But it is harder, because It is necessary to hold the equilibrium of the arrow.

Tongs are completely pressed against the surface, so small items are too grade without problems.

A big plus consider the material of the forceps. They are metal here. Hold the load and are strongly compressed. The rest of the hull is made of good quality plastics.

The disclosure of the bucket is possible up to 8 cm

Appearance:

Imitation under the appearance of real equipment is certainly super. Here you and metal rods and hydraulic cylinders, and all sorts of fasteners

A little imagination and all the soldiers will work out full-time without lunch and weekends in two shifts. Even the cabin looks like this, it's a pity only doors do not open

The cabin is highlighted by the red-blue LED together with sound accompanies of the action performed. Sound without light it is impossible to disable. Either all or nothing

Battery:

The battery hides in the rear compartment and closes on the plug.

Weighs the battery of 93 grams and approximately for 3 hours she charged at 1317mAh. The total game time is 20-30 minutes (depends on the frequency of simultaneously used functions).

I consider it a normal indicator, because Take a chance

The battery connector is the same in all my three radio-controlled toys, so I will consider it standard

Caterpillars:

Caterpillars rubber and fairly chain. If the boom is to maintain balance, then the slope under 45 degrees is climbing without problems.

Looks beautiful and realistic

Remote controller:

On the remote, everything is clear on the notation, but I will not say that it is super comfortable. It is necessary to get used to the first time to look at the prompts, which button what action does it perform.
Separately I note about the levers. They are responsible for a separate caterpillar, therefore, for moving back and forth, manage two levers simultaneously.

I decided to try to feed the cat) Cat sausage was delighted, but the sound of an unknown enemy scared a little, so the car brought food and began to wait for "bit"

Instead of playing video let's try to brew tea without hands

Output:

A plus:

Minus:

Thank you for reading to the end. Good luck to everyone ... And Mikhalych should still work))
