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.
