Mining dump truck 7540 BelAZ - technical specifications, features and reviews

The rapidly developing mining industry over the past decades has become the impetus for the production of quarry vehicles capable of transporting not only very heavy, but also bulky cargo. Among all the manufacturers that have ever produced quarry equipment, the most advanced enterprise is BelAZ. Cars of this brand can make a strong impression with their dimensions and technical characteristics. The BelAZ-7540 is not only distinguished by its enormous cross-country ability, but also has a serious carrying capacity.

These machines are operated in the most difficult conditions, access to which is very difficult, and the climatic conditions are not the most favorable. The machines are widely used throughout the world in the mining industry, as well as in the construction of large facilities for various purposes. BelAZ-7540 is the standard of power and high reliability.

How BelAZ was created

The history of this plant, and with it the car, dates back to the post-war period. In the difficult and distant year of 1948, a machine-building peat plant was built in the city of Zhodino, Minsk region.

In the first years, it practically did not work, but in 1958, the Minsk Automobile Plant transferred the production of MAZ-525 dump trucks with a carrying capacity of 25 tons. Although these products were not distinguished by quality, the production of these cars was carried out for quite a long time. At the same time, new models were developed. So, in 1961, the BelAZ-540 with a lifting capacity of 27 tons rolled off the plant’s assembly line. At the same time, the plant’s designers created a vehicle with a fantastic lifting capacity of 40 tons.

The plant has repeatedly received various high awards, including at international exhibitions. But this is not the limit for BelAZ. In 1969, the 75-ton quarry BelAZ-549 appeared, and in 1978, model 7419, capable of transporting up to 110 tons of cargo. Next, the plant produced BelAZ-75211 with a carrying capacity of 170 tons.

The BelAZ-7540 model has been produced by the plant since 1992. The dump truck is considered one of the best in the world. The car is the smallest among production cars, but its characteristics are not comparable to the features and capabilities of other trucks from global manufacturers. This dump truck was designed to transport rocks from the mining point to storage or processing points.

Vehicle Features

The conditions in which such transport is operated are by no means easy. Even if you do not take into account small distances (from 1 to 5 km), these vehicles have to move through difficult areas. The roads have a variable profile and a large number of turns. Often temporary roads are created in quarries, the surface of which is unsatisfactory. In addition, the roads consist of alternating ascents and descents of varying lengths. Therefore, a mining dump truck must have serious technical characteristics.

It should be noted that BelAZ-7540 is a whole family of models. As for the operating parameters, they are the same in all modifications. The only difference between them is the engines. These cars are also equipped with a torque converter gearbox, two types of brakes, a comfortable cabin with climate control and other functions.

Modifications and engines

The characteristics of the BelAZ-7540 depend on the engine that is installed in the car. Models 7540A are equipped with YaMZ-240 PM2 engines. The maximum net power of this unit is 420 hp, and the crankshaft speed will not be higher than 2100 rpm. This diesel unit has a volume of 22.3 liters, and the cylinders are arranged in a V-shape. The engine is not turbocharged. The cooling system is liquid type. The maximum torque is 1491 Nm at 1600 rpm.

The 7540V modification is equipped with a motor of the YaMZ-240M2-1 series. This model differs only in the presence of turbocharging and a pre-cooling system for the air flow.

The 7540S model is equipped with MMZ D-280 units. The power of this engine is 425 hp. at a crankshaft speed of 2100 rpm. This engine has 8 cylinders with a V-shaped arrangement. The engine capacity is 17.24 liters. The maximum torque is 1913 Nm at a crankshaft speed of 1300. The engine is equipped with a gas turbine supercharging system. In this case, there is an intermediate air cooling system.

The 7540 D series is equipped with imported eight-cylinder Deutz BF8M1015 engines. The power of such a unit is 350 horsepower at a crankshaft speed of 2050 rpm. The working volume of the cylinders is 16 liters. Maximum torque – 1835 Nm. Along with these models, there are other modifications in the series. They are equipped with engines from the American.

Fuel consumption

As you can see, all the engines are quite large. How much does the BelAZ-7540 consume? One point worth considering is quarry equipment. Fuel consumption here is not per kilometer, but per hour. So, in one hour, models A, B, and E consume 55.3 liters of fuel according to the passport. Model C – 59.77 l/h. Belaz D series needs 60.89 liters for one hour of engine operation.

Automatic transmission

Regardless of the configuration, as well as the modification, each car in this series is equipped with a torque converter automatic transmission. The transmission is distinguished by the presence of a three-shaft matching gearbox. The design also features a single-stage torque converter. The gearbox is four-shaft, equipped with friction clutches and an electric-hydraulic control drive. The transmission allows the use of five gears for forward movement and two for reverse movement.

To operate in light conditions, dump trucks can be equipped with an automatic transmission with four gears. Three are for forward movement, and one is for reverse.

Loading platform

The dump truck has a bucket-type platform. It is welded and has a protective visor. Additionally, it can be heated from exhaust gas energy. The platform is equipped with a special device for locking it in the raised position.

Frame

The chassis is welded, made from the most durable types of low-alloy steel. The spars have a box-shaped section and are distinguished by variable height. The spars are connected by cross members.

The design of the BelAZ-7540 is practically no different from other trucks, except for different overall dimensions.

Cabin and equipment

The car is equipped with a single all-metal cabin. It is located above the power unit. To get into the car, the driver needs to climb the stairs. There are two of these in the car - on the right and left sides. The interior is equipped with everything necessary for comfortable driving. The seat is equipped with a shock absorption system - so the driver can more easily endure shaking and vibration. Indeed, despite the large wheels, the car behaves very harshly on uneven surfaces, as noted by reviews. The chair is adjustable in height and also in length. There is an adjustable backrest angle.

Control devices are located directly in front of the driver's eyes. This greatly simplifies the monitoring of key indicators and vehicle systems. The dashboard has a tachometer, speedometer, pressure gauge for monitoring brake pressure, voltmeter and a meter that takes into account engine hours. Mirrors make it possible to fully control everything that happens behind the car.

This specialized machine is designed for operation in any terrain, in any climate. Therefore, the cabin has a system that maintains a comfortable microclimate. Reviews say that working behind the wheel of a BelAZ is quite comfortable.

Dump truck chassis

The BelAZ-7540 suspension is dependent for each axle. It contains pneumohydraulic cylinders filled with nitrogen and oil. Two of them are located on the front axle, two on the rear axle. Cylinder strokes are from 205 to 265 mm.

Brake system

The BelAZ-7540 mining dump truck is equipped with a drum-type working brake system with a pneumatic drive. There is also a handbrake controlled from the interior. In addition, there is a spare and retarder brake. The system has a separator to discharge condensate that periodically accumulates in the truck's air system.

Repair and service

The machine is serviced after operating a certain number of engine hours. It is necessary to carry out service activities regularly, otherwise the car may fail. TO-1 is performed every 100 engine hours or 2 thousand kilometers. TO-2 - after 500 hours or 20 thousand kilometers. The cost of spare parts and components is very high, and in the event of a breakdown, repairing a BelAZ-7540 can cost significant sums. But overall, the car is reliable because it was designed to work in difficult conditions. Some models have been successfully used for 25 years without major repairs.
