A gantry crane, also called portal crane, is a type of crane built atop a gantry with a single or double girder configuration supported by freestanding legs that move on wheels or along a track or rail system. Gantry cranes are usually considered when there is a reason not to incorporate an overhead runway system.

Unlike a overhead travelling crane, a gantry crane does not need to be tied into a building’s support structure—eliminating the need for permanent runway beams and support columns. In some cases, this can result in a significant reduction in material costs and can be a more cost-effective solution compared to a similarly specified overhead travelling crane.

Larger gantry systems may run on a rail or track embedded in the ground, typically in a straight line in a dedicated work area. Smaller portable gantry systems run on castors or wheels and can be moved about a facility for maintenance or light fabrication work.

Full gantry cranes are the most popular configuration—consisting of main beams and supporting legs at both ends of the main beam, which ride on rail that is mounted on the floor. They typically run in a straight line in a dedicated work area.

The semi-gantry crane is similar to the full gantry crane in its appearance and functions, except for the lack of the supporting leg on one side. So the rail on this side is not laid on the floor, but mounted on a wall, supports or a beam on a hall wall, similar to the bridge crane. This design gives the semi-gantry crane more flexibility and enables a greater reach than a conventional gantry crane. Ultimately, it allows the semi-gantry crane to work in areas that are inaccessible to the full gantry crane.

Portable gantry cranes, also names movable gantry cranes, are smaller lighter-duty gantry cranes that run on casters or rubber wheels. These wheels allow this crane to move freely throughout a facility to handle various materials or loads. When they’re empty and not under load, they can be moved or stored anywhere throughout a shop or into different work cells to offer greater space-saving and floor space flexibility.
