A hoist is a machine that performs a single task very well: lifting and lowering a load on a vertical plane (Figure 1, Motion 3). Hoists are situated on the primary horizontal beam of the crane, called the bridge girder.
What is the difference between a hoist and crane?
The main one is their range of movement. Hoists can only move loads up and down, while cranes can move loads up and down and side to side.
