Engine

Diesel engines with electronic control and central switching-off impeller of cooling system provide high specific power and consequently high speed of dump truck when driving uphill, as well as high fuel efficiency.

To facilitate starting of the engine at low temperatures mining dump trucks are equipped with engine liquid preheater, which provides heating of diesel fuel and coolant at starting of the engine.

Frame and Body

Long operating life of dump trucks is attained due to application of high-strength materials for frame and body manufacturing.

Hydraulic System

Integrated hydraulic system, designed with application of unified elements, provides structural simplicity and minimal power loss.

Provides cooling of oil without application of radiator in the design.

Hydromechanical Transmission

Hydromechanical transmission allows to choose the optimal traction and speed mode of motion which makes it easy to drive the vehicle and ensures safety.

Torque converter reduces the dynamic loads in the transmission and provides stable operation of the engine during changes of the loads.

Automatic control system of hydromechanical transmission improves performance of dump truck, increases service life and reliability by maintaining the optimum operating modes.

Multiple-disk Oil-cooled Brakes

Due to increased efficiency of the multiple-disk oil-cooled brakes and forced cooling system the average technical speed when driving on a slope is increased by 10...20%.

The response time of the multiple-disk oil-cooled brakes in the retarder mode is reduced by 4–5 times in comparison with the hydrodynamic retarder.

The nominal braking torque of the service and auxiliary brakes is increased.

Application of the multiple-disk oil-cooled brakes increases reliability of equipment and safety of operation.

Steering

The design of the hydrostatic drive eliminates mechanical feedback and ensures reliability in operation.

Low effort on the steering wheel, adjustable steering wheel angle and height, ergonomic and safety steering wheel provide safety, ease of operation and high level of comfort.

Small turning radius in combination with short wheelbase provides high maneuverability of dump truck.

Suspension

Pneumohydraulic suspension of mining dump truck with integrated hydraulic shock absorber in combination with the conventional system of the guiding apparatus provides high smoothness, performance, technical speed, lateral roll resistance and durability of dump truck components and comfortable working conditions for the operator.
