In the 1970-ies in the Soviet Union there was a question about creating a very powerful car that can help in building various large-scale energy facilities. The popularity it brought to machine, capacity above 40 tons, and the specifications they gave the opportunity them to easily move through careers. One such widely popular trucks was the BelAZ 7547, which will be discussed in this article.
A Powerful car produced in Belarus. Dump truck BelAZ 7547 developed for handling various rock mass in loose condition on the roads special purpose in terms of quarries. The machine can be used during the construction of large industrial and hydraulic facilities, and during construction of road systems. In addition, the truck is actively involved in enterprises related to the processing of raw materials. The car can overcome significant inclines, is almost not sensitive to the road surface and, indeed, indispensable during the transport of raw materials from the quarries with a high degree of water inflow.
Dump Truck BelAZ 7547 equipped with four-stroke, diesel engine, cylinders in which there are V-shaped. Cleaning the incoming air takes place by means of dry filters (two-stage or three-stage), are equipped with pollution sensors.
The engine's oiling system – mixed type, the liquid in it is circulated forcibly. The motor also has pre-heating, which is due to the liquid system. In addition, the presence of electrostarter and pnevmotechnika system start-up.

On the truck are the tires with pneumococci and the tread pattern of career performance. Provides a second option wheels – steel tubeless. Both can easily withstand loads in the range of 14500 kgs on each wheel, which gave the opportunity to increase the efficiency of the whole machine. High permeability and high load capacity of the vehicle is allowed to decline in many industrial facilities from the use of expensive in the domestic service railway lines.
BelAZ 7547 equipped with drum brakes with a separate pneumatic actuator for the front and rear wheels. Braking – drum. However, the designers also envisaged and the presence of the dry-plate (in some cases multi-disc) brakes.
