An overhead crane is a machine that moves a load horizontally across the ceiling of a facility rather than down corridors or on the floor. Overhead cranes have significant lifting power for material transport. The operator uses manual controls or a wired pendant station to control the crane’s motion.

Hoists can only move loads up and down, while cranes can move loads up and down and side to side. In the latter, a hoist serves as the component that provides vertical movement, while a trolley and bridge serve as the components that enable horizontal movement.

Understanding the three fundamental components of an overhead crane—the bridge, hoist, and controls—lays the groundwork for comprehending the complex machinery involved in material handling operations. Each component plays a crucial role in ensuring the safe and efficient movement of heavy loads.
