Applications of box girder single girder goliath crane

As a cost-effective single girder gantry crane solution, the single girder gantry crane with electric hoists have an extremely wide application both indoor and outdoor occasions due to the features of simple structure,light weight, low cost and good performance.

As a general overhead travelling crane, the single girder gantry crane is designed for light and moderate duty material handling , which is frequently used at open ground, ports, granite pit, cement pipe yard, open yard, container depots and shipyards, and indoor applications such as any workshop where overhead crane solution is needed but a bridge crane is not practical or a lifting crane is needed to work together with the existing overhead bridge crane, etc.

However,the single girder gantry crane is forbidden to handle melt metal, inflammable, or explosive loads and is not supposed to be used when the heavy duty crane with large tonnages is required.
