Wire Rope Winch | Rope Winches for Construction, Mining ...
Wire rope winch is a sort of drum winch onto which the rope winds. The drum is designed to release, retrieve and store the wire rope. During winching operation, the drum will rotate so as to wind the rope in and out. The resulting tension enables you to lift or pull a heavy load. Our winches come in a range of designs from electric powered ...

mining cage and skip
Jan 06, 2011· When the cage/skip is getting close to bank/bottom, if the winder is going too fast it will trip the winder, we are talking in manual control. In auto, as in mineral skipping, the winder starts slowing down within a "set distance" of loading/tipping levels, if it doesn't, slow banking takes over and again trips power to the winder.

Deep mining
And when existing mines go deeper, owners have to ask themselves whether it will be better to replace the surface hoist with something more powerful, or to add a secondstage hoist underground, say halfway down the mine, and do the lifting in two stages. Both solutions are possible. When designing hoists we have to balance very many factors. That is why it is so specialized. There is no such ...
