What is a gantry crane

A gantry crane is similar to a bridge crane, but instead of moving on suspended runways, the crane uses legs to support the bridge, trolley, and hoist. These legs travel on rails or on the tires. 

Gantry cranes are mainly used outdoors, but can also be used indoors. The gantry crane is ideal choice when you need a lightweight and quick knockdown crane for applications that require portability. It is also considered when there is a reason not to use overhead runway system and are most traditionally used in outdoor applications where full beams and columns can’t be installed, or they can be used below an existing bridge crane system. Gantry cranes are usually found in shipyards, railway plants, special construction sites like where a bridge is being built, or in places like steel mills and so on.
