JKMD Type Multi ripe mine hoist for deep mine shaft lifting

Detail

Product use, scope of use



Multi-rope friction hoist refers to a mining machinery and equipment used to lift minerals, lift personnel and materials. It is suitable for the hoisting system of shafts and inclined shafts in coal, non-ferrous metals, ferrous metals, non-metallic, chemical and other mines. It is composed of reducer, main wheel device, engine and other parts.


Features:

The height of the ordinary single-rope winding hoist is limited by the rope capacity of the drum, and the lifting capacity is restricted by the strength of a single steel wire rope. For deep mines and large output mines, the single-rope winding hoist can no longer meet the needs, so since 70 Since the years, the multi-rope friction hoist has been widely used.

The multi-rope friction hoist adopts the principle of flexible body friction transmission. The steel wire rope is placed on the friction wheel, and the friction between the wire rope and the liner is used to lift or lower heavy objects and personnel.

The multi-rope friction hoist is divided into two types according to the layout: pit tower type and floor type.

The multi-rope friction hoist is suitable for vertical shafts of coal mines, metal mines, and non-metal mines, and is used for lifting minerals and lifting personnel, materials and equipment.
