Hoist (mining) Wikipedia

Drum hoists are the most common type of hoist used in North America, South Africa and South America.When using a drum hoist the hoisting cable is wound around the drum when the conveyance is lifted. Single-drum hoists can be used in smaller applications, however double-drum hoists easily allow the hoisting of two conveyances in balance (i.e. one skip being lifted while a second skip is being

The Essential Role of Heavy-Duty Mine Skips in Underground

Skip Loading. Today, skip loading is usually automated along with dumping and ore hoisting systems. Two systems can be used for this purpose: volume-based or load-based measurement. The volume-based set-up is ideal for mines that harvest material of uniform density, with the occasional waste rock having lower density than the ore.
