BELAZ-7558R Series Mining Dump Trucks
Characteristics
General Specification
Application
BELAZ-7558R 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
Advanced Scanning System for Control and Braking
Advanced scanning system is installed for detailed environmental assessment.
Electro-hydraulic Steering and Brake System
The electro-hydraulic steering system and electronically controlled brakes provide greater flexibility and compactness of the steering system design, optimal control characteristics and interactions between the steering wheel and actuating hydraulic cylinders, brake pedal and brake gears.
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
Long operating life of dump trucks is attained due to application of high-strength materials for frame and body manufacturing.
Motor-Wheel Reduction Gear Unit
Bearing parts and gears of the motor-wheel reduction gear unit are made of the top-of-the-line alloy steels according to the most sophisticated technologies.
The applied kinematic scheme allows to transmit torque to the wheel hub simultaneously by the first and the second rows of the reduction gear unit and maximize the use of the space inside the wheel rim, reduces the actual loads in the reduction gear unit and provides its insreased service life.
Design solutions of the reduction gear unit eliminate the influence of deformations of gears and bearings of the unit that may occur during operation which makes it reliable and durable.
Robotic Complex
The new robotic complex “loader-dump truck” provides mining companies with completely new intelligent services.
Shuttle Driving Mode
The shuttle driving mode allows to save on tire wear, as well as reduce route time by up to 12% due to the absence of U-turns.
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.
Equipment
The manufactured equipment is equipped with additional units and systems that expand the functionality and improve operational attractiveness. There are standard and optional equipment sets. The set of equipment depends on climatic zone of operation: it can be northern or tropical.
Standard Equipment :
Heating and air conditioning unit
Rock ejectors
Fire-fighting system with remote actuation
Combined fire-fighting system with automatic actuation
Automatic centralized lubrication system
Loading and fuel control system
Telemetering tire inflation control system
Engine liquid preheater (except for tropical modification of dump trucks)
Video surveillance system
High-voltage line proximity alarm
Optional Equipment :
Combined fire-fighting system with automatic control and subsystem in the rear axle
Body bottom plate lining
Rock guards
