Diesel engines with electronic control and central switched impeller of cooling system provide high specific power and consequently high speed of dump truck
during uphill driving, as well as high fuel efficiency.
To facilitate starting of the engine at low temperatures dump trucks are equipped with engine coolant and fuel preheater, which provides stable operation of the system in various climatic zones, including Far North.
Correlation of power and speed characteristics makes it possible to approximate dump truck parameters to the characteristics of ideal theoretical stepless
Gear shifting is not require.
Smooth change of power while driving.
Algorithm of control system optimizes the parameters of the drive system.
Provides minimal operating costs and higher productivity of transportation and does not contain units exposed to wear.
MOTOR-WHEEL REDUCTION GEAR BOX
Load-bearing part parts and gears of motor-wheel reduction gear box are made of the finest alloy steels with the latest technologies.
The kinematic scheme applied in the design of the reduction gear box allows transferring torque to the wheel hub at the same time by the first and second row of gears and making the most of the space inside the rim, reducing inner loads and increasing service life.
The design of the reduction gear provides replacement of any of its parts without removing the tire, which reduces the time for maintenance and repair.
The design of motor-wheel reduction gear box features hub cuff of smaller diameter, which reduces the sliding speed and increases reliability and service life of the unit. The system of grease supply for hub cuffs connected to centralized lubrication system of the truck serves the same purpose.
Engineering solutions of motor-wheel reduction gear box design eliminate the influence of the in-service deformations on operation of gears and bearings of reduction gear box, making it reliable and durable.
Significantly reduces mechanical wear of friction materials of brake linings. Provides efficient slowdown within whole speed range down to zero speed.
Allows switching from traction mode with full torque to braking mode with full braking torque in less than a second.
Pneumohydraulic suspension with integrated hydraulic damper in combination with the conventional guiding system provides smooth driving, high performance, technical speed, resistance to sideway rolling and durability of the truck units and comfortable environment for the operator.
Combined hydraulic system for steering, brakes and body hoist allows to unify hydraulic drive and reduce the number hydraulic units in the drive system.
The use of controlled pumps with automatic unloading helps to reduce power losses in the drive and provides cooling of oil in different climatic zones without the use of radiators.
Design of front and rear service brakes and parking brake is developed with application of a single unified brake pad.
Developed area of friction material of brake pads allows to use the parking brake system to stop the dump truck in an emergency situation.
Pneumatic drive features up-to-date dryer with absorber to prevent freezing of pneumatic devices at low temperatures.
Hydrostatic drive design ensures eliminates mechanical feedback and provides rational distribution of hydraulic units on the chassis.
Availability of hydropneumatic accumulators ensures safe control in an emergency situation.
Small turning radius, combined with the short wheelbase of the trucks provide high maneuverability.

Drivers of "Kuzbassrazrezugol" have always operated new models of BELAZ trucks, starting almost from the first chassis numbers. There is an intensive exchange of operating experience on the basis of which BELAZ design engineers implement changes in the design of trucks to provide more reliable and productive operation. In September 2005, OJSC “Belarusian Autoworks produced the first prototype of BELAZ-75600 with carrying capacity of 353 short tons. The first truck of this series passed acceptance testing in "Kuzbassrazrezugol". The results of the tests show that the use of dump truck BELAZ-75600 provides a performance improvement of 35-40% and a corresponding reduction in the cost of transportation operations. The first production batch of Belarusian giants today successfully operates in mines of “Kuzbassrazrezugol" company.
