BELAZ-7557 Series Mining Dump Trucks
Characteristics
General Specification
Application
BELAZ-75570 mining dump trucks are designed for transportation of loosened rock in severe mining conditions of deep open pit mines on haul roads under various climatic operating conditions. These trucks can be used in construction of large industrial and hydraulic structures, highway systems, as well as in manufacturing departments of the processors. Depending on the specific weight of the transported cargo, the greatest efficiency is achieved when operating with excavators and loaders with buckets of the following capacity: 12.5-18 m³.

Competitive advantages
Braking System
The design of the truck uses multiple-disk oil-cooled brake gears of a new design providing:
-increased resource of the brake system;
-increase of the average technical speed of the truck when driving downhill by 10-20%;
-reduction of the response time of the multiple-disk oil-cooled brake in the mode of the retarder (compared with the hydrodynamic retarder);
-increasing the nominal braking torque of the service and auxiliary brakes.
Cab
The comfort and safety of operator's work are assured through comfortable cab.
Design of cab and body with protective canopy provides conformity with ROPS and FOPS safety requirements.
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, which significantly increases engine service life and ensures reliable operation of the system in various climatic zones, including the Far North.
Frame and Body
The long operating life of dump trucks is attained due to the application of high-strength materials for frame and body manufacturing.
Hydraulic System
The integrated hydraulic system provides optimum operating parameters as well as ease of maintenance and repair.
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 the performance of dump trucks, increases service life and reliability by maintaining the optimum operating modes.
Steering
Hydrostatic steering provides ease of control and high maneuverability of the truck.
Suspension
The best smoothness and, accordingly, the minimum dynamic load on the operator and the units and components of the truck.
Low dry friction.
The design of the suspension cylinders provides minimal labor and cost during maintenance and repair.
Wheelbase
The short wheelbase of the truck ensures high maneuverability.
