Introduction
The Double girder gantry crane is the ideal handling device for outdoor work. Cantilever can be added on both sides of the main beam(usually the cantilever length is 1/4 of the span), The distance between the straight legs can be increased to facilitate the passage of larger goods from straight legs. The power supply can be supplied by cables, sliding contact line and diesel generators. Our crane can meet your various requirements.
DAFANG gantry cranes are designed with FEM standards. The weight of the whole machine is reduced by more than 15%, and the reduction of wheel pressure is 10~20%. Each part is bolted for easy installation and Transportation. Crane and trolley run smoothly, frequency conversion, low noise. If the lifting height is more than 15m, we will be equipped with an anemometer. If the span is greater than 35m, we will use flexible legs and electronic correction. Our crane working duty from A3 to A7. It is widely used in steel, infrastructure, port container handling, freight yards, warehouses and other occasions.
