Mining Hoisting Methods

Hoist (mining) - Wikipedia

In underground mining a hoist or winder is used to raise and lower conveyances within the mine shaft.Modern hoists are normally powered using electric motors, historically with direct current drives utilizing Ward Leonard control machines and later solid-state converters (), however modern large hoists use alternating current drives that are variable frequency controlled.
