The term "gantry crane" tends to get thrown around a lot in the material handling industry. We often find that when folks say gantry crane, they're often referring to an overhead bridge crane system. A gantry crane and bridge crane are actually very different types of overhead cranes. A gantry crane is a type of overhead crane 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.

These are typically used for an outdoor application or below an existing overhead bridge crane system. Unlike a bridge 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 bridge crane.
