Box Girder 20 Ton Single Girder Gantry Crane For Workshop Loading
Introduction:
L-type single-girder gantry cranes are mainly used for loading and unloading of outdoor cargo yards, storage yards and bulk cargo. The metal structure is like a door frame. Two outriggers are installed under the main beam, which can be directly on the track. There can be cantilever beams at both ends of the main beam. The gantry crane has the characteristics of high site utilization, wide operating range, wide adaptability and strong versatility.
Box girder:
The steel plate is welded into a box-type structure, which has the characteristics of high safety and high rigidity. Generally used for large tonnage and super tonnage gantry cranes. As shown in the overview picture MGhz1200, with a lifting capacity of 1200 tons, is the largest gantry crane in China, and the main beam adopts a box girder structure. Box girder also has the disadvantages of high cost, heavy self-weight and poor wind resistance.
