Double Girder Gantry Crane
According to the difference of the door frame,we devide the double girder gantry crane into two categorites:
U-type double girder gantry crane
This type gantry crane adopts U type door frame, it consists of main parts, namely, the bridge structure, the traveling mechanism, the cart and the electric equipment.
A-type double girder gantry crane
This type Gantry Crane adopts A-type door frame. The bridge is welded structure of box-type; individual drives are adopted for traveling mechanism on each end of the crane. All movements of the crane are controlled in the cabin.
This crane is composed of bridge, crane traveling mechanism, trolley, electric equipment. The frame adopts box-type welding mechanism. Crane traveling mechanism adopts separate drive. All mechanisms are operated in the driver cabin. Power supply of crane adopts cable and sliding wire, select one when ordering.
It can be used for general service, such as lifting and transferring work in shops, docks and warehouse.
Gantry cranes have become a widely accepted alternative to overhead cranes. This type of crane is similar to the overhead crane except that it runs on a runway at the floor level. The bridge is supported by a pair of rigid steel legs which are carried by a pair of end trucks along the floor level runway.
