CE MG 39.4m/Min 32/5 Ton Double Girder Gantry Crane Lifting Heavy Loads

CE Certified Double Girder Gantry Crane For Heavy Load Lifting And Transport

Description:

The double main girder gantry crane has strong bearing capacity, large span, good overall stability and many varieties, but its own quality is larger than that of the single main girder gantry crane with the same lifting capacity, and the cost is also higher. According to the structure of the main beam, it can be divided into two forms: box beam and truss. Generally, a box-shaped structure is used.

Main beam structure:

1. Truss beam
The structural form welded by angle steel or I-beam has the advantages of low cost, light weight and good wind resistance. However, due to the large number of welding points and the defects of the truss itself, the truss beam also has the disadvantages of large deflection, low rigidity, relatively low reliability, and frequent inspection of welding points. It is suitable for venues with low safety requirements and small lifting capacity.

2. 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. Box girder also has the disadvantages of high cost, heavy self-weight and poor wind resistance.

Application:

Double girder gantry crane is mainly used in Steel, Forest Products, Intermodal, Biomass/Pellet, Concrete warehouse, rail station, stock yard and shipyard, and many other industries.
