A Single Girder Gantry Crane is a type of lifting machine used to move heavy materials in outdoor or large indoor spaces. It features a single horizontal beam, or girder, supported by two legs that run on tracks. This design allows the crane to move loads along the tracks, much like a bridge crane, but with the added benefit of being able to work in open areas, such as construction sites or ports. It’s an efficient and cost-effective solution for lifting and moving materials, especially when a large, permanent overhead crane system is not feasible.
