Tipper tires. Reinforced Dump Truck Tires Basic Requirements for Dump Truck Tires

A dump truck is a heavy equipment designed for working in quarries. Special requirements are imposed on the tires for such machines. First, they must provide excellent cross-country ability. Secondly, rubber should not lose its properties when the temperature drops or rises. Thirdly, the tire must always be resistant to high moisture and abrasive soil.

Usually truck tires for dump trucks are made in a tubeless design, equipped with a high-strength frame and several layers of material. This ensures reliability and wear resistance.

Basic requirements for dump truck tires

The wheels of mining special equipment are distinguished by serious dimensions, which means that the main point is the balancing factor. In the presence of the slightest imbalance, vibration will occur, which will lead to poor controllability and accelerated wear. To prevent the impact of negative factors, a rigid and high-strength frame is used. It also has a positive effect on the carrying capacity of the machine.

One of the main points is the tread pattern. Tires should have developed lugs formed from deep, large grooves. The width of these elements usually matches the width of the boxes. This design provides an optimal lateral area, which contributes to the "pushing" of the soil and the correct "push" from the soil surface. The result is a confident ride in mud, snow and sand.

Dump trucks are operated in conditions of a large amount of debris. The large grooves combined with the directional tread pattern help the tires self-cleaning quickly. Choose models with serious depth and width - this way you protect the equipment from slipping due to contamination.

Remember! Tires with developed lugs can be used for driving on roads with concrete or asphalt surfaces, however, this will cause increased consumption fuel.

Who is stronger?

The very concept of "reinforced tires" is confusing for some carriers. And this is understandable, since for many of those who are engaged in the transportation of bulk cargo, rubber, in fact, is consumable... The mileage before tire write-off due to the destruction of the power structure often does not exceed 20,000 kilometers. And this is actually only six months of the truck's work on a short shoulder. In addition to rupture from overload, the tires of dump trucks also fail due to side cuts, which, as you know, are practically impossible to repair. There are many cases when, due to a cut in the sidewall, the tire of a dump truck was written off after a run of 5-10 thousand km. In this situation, the only thing that worries transport workers is where to buy new tires at a cheaper price. It is gratifying that in the wake of the rise in currency prices, the products of domestic tire factories, which have in their arsenal not only reinforced combined tires, but also modern all-steel models of reinforced construction, are of increasing interest. For the sake of fairness, we note that the first ones have practically left the stage, passing the baton to the second type of tires.
Nonetheless, reinforced combo tires are present in the product lines of a number of manufacturers. One of them is Belshina OJSC, which has a reinforced combined tire 10.00 R20 mod. Bel-114 ns18 bearing capacity index (single / double) - 149/143, according to GOST 5513 - ns16 - 146/143.
However, we emphasize once again that most manufacturers have relied on SSC technology, and this explains most of the proposals for reinforced tires specifically of this type... It is noteworthy that among the domestic solid steel in this segment there are also new items. One of these is an all-steel tire with a reinforced tread pattern, a reinforced breaker structure in the most massive standard sizes 315 / 80R22.5, 11R22.5 and 13R22.5, model DM-1 brand Cordiant Professional... It is intended for completing dump trucks operating in open pit and off-road conditions. Nevertheless, foreign companies are still the leaders in the production of reinforced tires. And the best evidence of the quality of their tires is the fact that the leading European car manufacturers equip their dump trucks with them.
Now we will clearly indicate that there is a reinforced tire. According to a number of experts, these are tires with a bearing capacity index higher than indicated in GOST. So that carriers can navigate the indices and compare them with the load value, we provide a corresponding summary table. Guided by its data, having in hand the technical passport of the tire, you can easily determine whether the tire will withstand the design load. It is noteworthy that some car manufacturers, completing dump trucks with rubber, deliberately install tires with a higher index on them and at the same time do not take money from the carriers for this gift. Moreover, the difference in rubber is observed in cars intended for European and Russian markets... For example, a dump truck in Europe is standardly equipped with tires with a carrying capacity index of 154 (load 3750 kg), and in the Russian version for the same model rubber is coming with the 156th index (load 4000 kg). That is, the difference in load is a substantial 250 kg per wheel. And the three-axle dump truck has ten of them, and the four-axle dump truck has twelve. When a carrier, satisfied with the mileage of tires that were installed on the conveyor, buys similar tires instead of worn ones, but with a “step” lower index, as the sellers recommend to him, then he cannot reach the previously obtained mileage of tires, all other things being equal.
Further. The reinforced tire uses different cords in the carcass and belt. There is also a reinforced side structure. And the tread compound contains components that increase abrasion and cut resistance. It is the last set of measures to modernize the tires that allow you to carry more cargo.
A reasonable question arises: how much more can you take on board? Alas, there is no definite answer. A number of tire manufacturers officially justify the use of reinforced tires not by the possibility of increasing the tonnage, but by the ability of tires to work in heavier ones. road conditions... At the same time, they admit behind the eyes: "Yes, you can work with overload." So which one? To answer this question, let us take some averaged values ​​that were voiced by the experts, and extrapolate the data to dump trucks with a carrying capacity of 20 tons. So, if you believe the data received, then reinforced tires can add about 10% to the indicated tonnage or a "cap" of two tons. That is, after completing ten walks with overload, the sixth can be attributed on completely legal grounds. Frankly speaking, we do not recommend relying in calculations on the upper values, which were indicated by the numbers 20 and even 25% "above the norm": this will negatively affect the dump truck. Although in the practice of dump transport, 40% of overload is not the limit! However, we emphasize once again: it is important that the truck chassis has the required safety margin. The ability of a machine to efficiently perform a transport task with overload depends also on the driver. It is on the professionalism of the drivers that some of our transport experts have emphasized. Moreover, practice has proven: experienced driver in some cases, it will be able to save tires, even if its dump truck was accidentally overloaded. To save rubber, it is necessary to reduce the speed of transportation according to the weight of the transshipment. At the same time, the dynamic load on the tires will decrease, and they will reach their destination without destroying the carcass.
