Design of cab and body with protective canopy provides conformity with ROPS and FOPS safety requirements.

Engine

Diesel engines provide high specific power and 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.

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.


Steering

The 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.

The small turning radius in combination with a 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.

Wheelbase

The short wheelbase of the truck ensures high maneuverability.
