The MDG-type gantry crane consists of the gantry frame, trolley, crane traveling mechanism, operator’s cabin, and electrical control system. The gantry adopts a box-type structure, with the trolley running on one side of the main beam. For lifting capacities below 20 tons, the trolley uses a vertical anti-derail roller design; for capacities above 20 tons, a horizontal anti-derail roller design is used. The main beam features a single-beam, offset rail structure, while the support leg is L-shaped, providing a large lifting space and strong outreach capability, making it easy to transfer loads from inside the span to under the cantilever.

This crane is widely used in factories, mines, enterprises, railway stations, and ports. It offers advantages such as light self-weight, reduced material usage, lower cost, and a smaller windward area.
