7557 SERIES OVERVIEW
Mining dump trucks with payload capacity of 90 tonnes are designed for transportation of rocks in severe mining conditions of deep pits, at open-cast mining of mineral deposits on technological haul roads under various climatic operating conditions (ambient temperatures from -50 to +50 degrees Celsius).
Characteristics
| Modification | Load capacity, tons | Engine | Engine power, kW | Transmission |
|---|---|---|---|---|
| BELAZ 75570 | 90 | QST 30-C | 783 | hydromechanical |
| BELAZ 75571 | 90 | Cummins QST 30-C | 783 | hydromechanical |
7557 SERIES CHARACTERISTICS
Designed for transportation of loosened rocks on technological haul roads at open-pit mining sites under different climatic conditions. These trucks can be used in construction of large industrial structures and hydraulic facilities, in construction of highway systems as well as in technological departments of the enterprises of processing industry. Depending on relative density of the transported materials maximal efficiency is achieved during operation with excavators and loaders with the following bucket capacity: 12,5 — 18 m3.

| Width | 5400 (6150***) mm |
| Height | 5340 (5410***) mm |
main CHARACTERISTICS
| Capacity | 90 mt |
| Engine | QST 30-C |
| Engine power | 783 kW |
| Transmission | hydromechanical |
| Transmission Formula | 6+1 |
additional CHARACTERISTICS
| Torque Nm / r / min | 4630 / 1300 |
| Fuel rate @ nominal power, g/kW*h | 204 |
| Tires | 31/90-49; 27.00R49 |
| Rear Axle | mechanical, with single-stage main gear, bevel differential and planetary wheel gears |
| Suspension | pneumohydraulic, conventional for front and driving axles - trailing arms with central hinge |
Brakes (with hydraulic drive)
| front wheels | dry single-disk brakes |
| drear wheels | multiple-disk oil cooled brakes |
