Single Girder Overhead Crane

Single girder overhead crane adopts CD1, MD1 type electric hoist as its lifting mechanism to realize the moving or turning over for lifting goods through moving up and down of hook, moving left and right of trolley and moving back and forth of the crane. The cranes are widely used for many work occasions such as mechanical processing, assembly, maintenance and warehouse, special-purpose crane is used for working in a particular condition and environment, such as explosion-proof single girder crane, metallurgical single girder crane.

The overhead crane consists of main girder, end carriage, electric hoist, electrical equipment, crane and trolley traveling mechanism and so on. The main girder is made by using the overall pressure groove, simple structure and good process. Manufacture of the end carriage is the same to the main girder. The main girder and end carriage are connected by bolts which is easy to disassemble, transport and store.
