Overhead travelling crane
Overhead travelling crane
The overhead travelling crane, commonly called the bridge crane, consists of metal framework, lifting mechanism, travelling mechanism, and electric control systems. The metal framework spans the rail center distance, and the lifting mechanism travels along the main beam of the crane. The rail center distance is the distance between the centers of two parallel rails, which are mounted on longitudinal load-bearing beams and fixed to opposite steel columns by brackets.
This type of crane is most commonly used in workshops, warehouses, power plants and factories. Overhead travelling crane can be operated by pendent control handle, wireless remote control or operation cabin

On a single girder overhead travelling crane, the metal framework consists of one main beam supported on each side by an end beam. The lifting mechanism adopts electric hoists which are most commonly underhung—meaning they run on the bottom flange of the main beam.

Double girder overhead travelling crane
Double girder overhead travelling crane
On a double girder overhead travelling crane, the metal framework consists of two parallel main beam supported on each side by an same end beam. The lifting mechanism adopts electric hoists or trolleys which usually run on tracks laid on two parallel main beams. This type of cranes are recommended for heavy-duty applications where the crane has to handle heavier capacities and longer spans. Because of this, the components of the crane system, including the electric hoist and trolley, are more complex in design—making double girder cranes more expensive than a single girder crane.

Suspended overhead travelling crane
Suspended overhead travelling crane
The rails of a suspended overhead travelling crane are secured to the ceiling of the building. The elimination of dedicated support columns provides additional floor space, but limits lifting capacity.
