The machine serves to transport mined material in gas (methane) and coal-dust hazardous mines in temperatures up to +35 C and humidity up to 98%.
The mine car can be manufactured with 660V or 1140V electric drive; all electric equipment is explosion-proof. The travel drive is equipped with two three-speed motors; all wheels are driving and steering. The front axle is balanced, the rear axle is bolted to the car frame.
The mine car has a service, parking and emergency brake systems. The service brake system has brake pads in the wheel; the parking brake pads are in the drives. The service brakes started by hydro-pneumatic accumulator work for emergency brake system.
The drive of the drag-type conveyor is a two-speed motor. The speed of the moving chain has been increased to 0,4-0,5 m/sec. The conveyor chain is of round-link type. The cable reel capacity is 200m. In the front part of the mine car there are two hydraulic jacks for mounting 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 composite for easy descending the machine down the mine. Max. dimensions and mass of the parts – 5500x2500x500mm; 1800kg. Max. dimensions and mass of the body parts – 5500x2500x550mm; 1500 kg.
The mine-car design is multifunctional and can operate in potash and coal mine.
