Hoist (mining)
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 solidstate converters, however modern large hoists use alternating current drives that are variable frequency controlled. There are three principal types of hoists used in mining
