Application

Mobile double girder gantry crane is widely using for lifting and loading, unloading works in outside warehouse or railway stations. Using in road construction area, material stocks area, cement plant, granite industry, construction industry, engineering industry, railway etc. This type crane is widely applied to the railway goods yard, big tonnage port, open storage, the container transfer station, and etc. to handle with the frequent loading and unloading works.

Product Description

1. Mobile double girder gantry crane consists of below main parts: the bridge structure, the trolley traveling mechanism, crane traveling mechanism and the electric equipment, This crane use one or two trolley as its lifting machine, comprising the crane and trolley traveling mechanism, lifting mechanism, cabin, computer room, electric room etc.

2. The lifting mechanism is electric trolley, it can equip with hook and other tools to lift containers. Some rail, gear, wheel relevant parts with good quality manufactured by our own group, the quality is easily been controlled.

3. Mobile double girder gantry crane has two kind conductive forms: cable and slip line. Slip line are first recommended.
