[0002] The single-girder bridge crane is a lifting equipment that spans over workshops, warehouses, and yards for material hoisting. Since its two ends are seated on tall cement columns or metal brackets, it resembles a bridge. The bridge of the single-girder bridge crane runs longitudinally along the tracks laid on both sides of the elevated racks, and can make full use of the space under the bridge to hoist materials without being hindered by ground equipment. It is a kind of lifting machinery with the widest application range and the largest number.
