PRODUCT INFORMATION

The double girder overhead crane is widely used in lifting 5t~50t stuff. It’s very convenient to install and operate with various functions in workshops, metallurgy,warehouses and assembly shops etc.

It is generally composed of mechanical, electrical and metal structures.

Mechanical part: it is divided into three institutions namely lifting mechanism, trolley running mechanism and big car running mechanism. The lifting mechanism is used for vertical lifting objects, and the car running mechanism is used to carry the load for transverse movement. The big car run mechanism is used to make the lifting trolley and the articles to move vertically to achieve three-dimensional space to carry and unload the cargo.

Metal structure: consists of main girders, end carriages, hoist, trolley and rails.

Electrical components: electrical equipment and electrical wiring.

APPLICATION

It is widely used in workshops, metallurgy, warehouses ,assembly shops,industrial and mining enterprises, steel and chemical industry, railway transportation, port wharf, logistics and other departments and places.
