1. single girder

Single girder gantry crane has the advantages of simple structure, convenient manufacture and installation, its quality is small, the partial rail box frame structure. Compared with the double girder gantry crane, the overall stiffness is weaker. Therefore, when the weight is Q = 50t, S = 35m span, can use this form. L type and C type two forms of single girder gantry crane legs. L type of manufacture and installation is convenient, the situation is good, its own quality is small, however, the lifting of cargo through the supporting legs of the space is relatively small number of. The C shaped support legs are bent or bent, and the purpose is to have a larger transverse space so as to enable the goods to pass through the supporting legs.

2. double girder

Strong ability of bearing double girder gantry crane, span is big, the overall stability is good, many varieties, but its quality with the same play weight of single girder gantry crane compared to larger, the construction cost is also high. According to the different structure of the main beam, it can be divided into two types of box girder and truss. Generally use box structure.
