An overhead crane, also known as a bridge crane, is a type of crane where the hook-and-line mechanism runs along a horizontal beam that itself runs along two widely separated rails. Often it is in a long factory building and runs along rails along the building's two long walls.
Overhead cranes typically consist of either a single beam or a double beam construction. There are 2 types of overhead cranes
Top Running/Overslung or
The heavier capacity cranes tend to be Overslung.
Overhead cranes can be built using typical steel beams or a more complex box girder type.
Double girder bridges are more typical when needing heavier capacity systems from 10 tons and above. The box girder configuration results in a system that has a lower deadweight but a stronger overall system integrity. This system includes a hoist to lift items, a bridge that spans the area covered by the crane, and a trolley to move along the bridge.
