A Type Double Girder Gantry Crane Capacity: 5t-320t Span Length: 18-35m

Double girder gantry crane is a professional machine for material handling, and it can be designed in different working duty(ISO A3~A7) according to user’s requirements. So the crane is widely applied to material stocks area, cement plant, granite industry, construction industry, engineering industry and so on.

It is composed of double main girder, four supporting legs, two sets sills, hoisting trolley, cab and electrical control system. As to the control method, it could be ground control, remote control, cabin control or both. If the working temperature is high, air conditioner can be equipped in cabin for the operator.

Double girder gantry cranes can be divided into the following types according to the shape of main girder and supporting leg:

1.Box type double girder gantry crane without cantilever

2.Box type double girder gantry crane with single cantilever

3. Box type double girder gantry crane with double cantilever

4. Truss type double girder gantry crane without cantilever

5. Truss type double girder gantry crane with single cantilever

6. Truss type double girder gantry crane with double cantilever

Box type is a stronger and compact design, while the truss type has more powerful wind resistance, so if your place is a windy area and the crane works outdoor, the truss is a better choice.
