This type of overhead crane is configured with a single bridge girder, two end trucks, and a trolley hoist which runs along the bottom flange of the bridge girder between the end trucks. A single girder crane is easy to install and is generally used in applications that require light to medium lifting or in buildings where headroom is limited.

These overhead cranes are motorized and typically feature radio controls. They are available in either top running or under running on a track.
