Underhung Bridge Crane

A bridge crane is a lifting device used to lift materials above workshops, warehouses and material yards. Because its two ends are located on concrete columns or metal brackets, it looks like a bridge. The bridge of the bridge crane runs longitudinally along the tracks laid on the elevated platforms on both sides, making full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and largest type of lifting machinery.
