Main beam structure

1. truss beam

Structure using I-steel welded together, has the advantages of low cost, light weight, good wind resistance. However, due to the defects of the welding point and the truss, the truss beam has large deflection, small rigidity, low reliability, and so on. Applicable to the safety requirements of the lower, the smaller the weight of the site.

2. Box Girder

The use of welded steel box type structure, has the advantages of high safety, rigidity etc.. Generally used for large tonnage and large tonnage gantry crane. Such as the MGhz1200, the weight of 1200 tons, is the largest gantry crane, main girder with box girder structure. At the same time, the box beam has the disadvantages of high cost, great self important, poor wind resistance and so on.

3. cellular beam

Generally refers to the isosceles triangle honeycomb beam, the beam end is a triangle, on both sides of the diagonal with honeycomb holes, the upper part and the lower part of a chord. The cellular beam absorbs the characteristics of the truss beam and box girder, which has larger stiffness, smaller deflection and higher reliability than the truss beam. But because of the use of steel plate welding, the weight and cost ratio of truss beam Shaogao. Suitable for use in frequent or high weight field or beam field. Because of this type of beam type for patent products, so manufacturers less.
