Technical characteristics
The mine car has a service (in every wheel), parking (in every drive) and emergency brake systems. The service brakes started by hydro-pneumatic accumulator work for emergency brake system.
The drive of the drag-type conveyor is a three-speed motor. The conveyor chain is of round-link type 18x64 with the load of failure up to 40 t.f. In the mine car there are four hydraulic jacks for dismantling of the wheels. The operator’s cabin is two-position; the cable reel drive is actuated by the hydraulic engine; the reeling is automatic.
All the units including the body and the frame are of composite type which makes the descending of the machine down the mine easier. Max. dimensions and mass of the parts – 5800x2900x1300mm; 3370kg.
