Multi-rope friction hoist is a kind of mine machinery and equipment used for lifting minerals, lifting personnel and materials. It is suitable for vertical shaft and inclined shaft in coal mine, nonferrous metal, nonmetal, chemical industry, etc. It is composed of reducer, main wheel device, engine, etc.
The height of single-rope winding hoist is limited by the volume of roller, and the lifting capacity is limited by the strength of single wire rope. For the mine with deep well and large output, single-rope winding hoist can no longer meet the needs, so multi-rope friction hoist has been widely used.
Multi-rope friction hoist is a flexible body friction transmission principle, steel wire rope on the friction drum, the use of the friction between the wire rope and the liner to lift or lower the weight and personnel.
Multi - rope friction hoist, according to the layout into tower type and floor - type.
Multi-rope friction hoist is suitable for vertical shaft of coal mine, metal mine and non-metal mine, and is used for lifting minerals and lifting personnel, materials and equipment.
