Structural form of gantry crane

Gantry crane is a deformation of bridge crane. It has a wide range of uses and adapts to a wide range. It is the best choice for users. So do you know its structure?

Composition of gantry of gantry crane:

1.  Upper bridge
2.  Kantilever
3.  Outrigger
4.  Lower cross beam

Gantry cranes are generally classified according to gantry structure, main beam and spreader.

Door frame structure

1.  Full gantry crane: the main beam has no overhang, and the trolley is carried out within the main span.
2.  Semi portal crane: the outrigger has height difference, which can be determined according to the civil engineering requirements of the use site.
3.  Double cantilever gantry crane: the most common structural form. The stress of its structure and the effective utilization of site area are reasonable.

Composition of gantry crane:

1.  Generally, the crane operating mechanism only uses four driving and driven wheels
2.  The metal structure of the bridge is composed of main beam and end beam, which is divided into single main beam bridge and double beam bridge.
3.  The main beam is rigidly connected with the end beam, and wheels are installed at both ends of the end beam to support the bridge running on the elevated.
4.  The cross sections of the deflection box double girder and the deflection box single girder are composed of upper and lower flange plates and main and auxiliary webs of unequal thickness.The trolley rail is arranged above the main web, and the short stiffener plate in the box body can be omitted. Among them, the deflection box single girder is replaced by a wide flange box girder, which has small self weight but complex manufacturing.

The above is the details of the structural form of the gantry crane. I hope it will be helpful to you.
