Gantry crane

The gantry cranes operate normally in the open environment because the guide rails are positioned on the ground. As for bridge cranes, the structure can be in single beam version for small/medium loads and double girder for medium/high loads. The size can be substantial, both in gauge (light) both in height; they can also be provided with protrusions on one side or both over the track gauge. There are various solutions with cranes with "drawn up" parts on the ground on one side only, which are defined as "lame".
