Nov 19, 2021

As a lifting tool, double girder gantry crane is widely used in modern factories, bulk cargo terminals, container yards and warehouse dispatch operations. It has the advantages of large lifting capacity, large span, multi-function, high efficiency and so on.

The system structure of gantry crane mainly includes main beam, outrigger, running track, hoist trolley, driver's cab, etc.

The main beam extends in the left and right direction. The left and right ends of the main beam are respectively fixedly connected with legs. The legs are equipped with supporting bodies for placing rod-shaped materials. They are located between the two legs and are distributed in the front-to-back direction or extend in the front-to-back direction.

During construction, the rod-shaped materials such as rails are placed on the support body, and the rod-shaped materials and the support body move together with the crane. In this way, the rod-shaped materials are transported by the crane at the construction site, eliminating the need for transportation vehicles on the construction site. Reduce construction costs and improve construction efficiency.
