This distance is often referred to as the fleet angle. The ropeis wrapped around the drum. In general, drum hoists are considered to be more flexible than friction hoists. They are considered to be more flexible in terms of use because they can operate iFriction hoistFriction hoists or Koepe hoists are the second main type of hoist. Instead of a drum located some distance away for the shaft, as in drum hoisting, the drum is directly above the shaft itself. Rope passes over the wheel during hoisting operations.

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

This must be strong enough to hoist the total load, including its own weight, and to withstand the starting-stresses due to picking up the load suddenly when the rope is slack. Experiments have shown that, in starting with six inches of slack rope, the stress in the rope is about double that due to picking up the load gently. Expressing these stresses in a formula, let K = stress in rope in pounds, at the head sheave, at t
