SEVENCRANE underhung double girder bridge crane is a commonly bridge crane with electric trolleys. The performance parameters of the double-girder bridge crane include: lifting capacity, lifting height, span, mechanism working speed, working level, wheel pressure, etc.

SEVENCRANE underhung bridge crane is a lifting equipment that is placed horizontally over workshops, warehouses and yards for lifting materials. Because its two ends are located on tall cement pillars or metal supports, it looks like a bridge. The bridge of the bridge crane runs longitudinally along the tracks laid on the elevated structures 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 most numerous type of lifting machinery.
