Mine Hoist Disc brake lifting equipment for mining with flexible action
This series mine winches for mining are mainly used for mine shaft and inclined shaft to life coal, ore, waste rock as well as lifting personal, materials, tools and equipment. The principle axis unit used split or integral type flexible struction drum and the drum suffers force uniformly with big strength. Disc brakes of mine winches are rear mounted fuel tank with flexible action. The hydraulic can delay secondary brake, and it can be automatically released in wellhead. Double-drum hoisting machine has rope-adjusting cluth with radial teeth. Transmission parts can be equipped with planetary reducer or parallel axis hardened reducer. Electrical parts of mine winches has necessary protection and interlock device, and user can choose PLC electrical controller and frequency speed-changing electrical controller. Dynamic braking of mine winches is also available on request.
