Bridge Crane is a bridge type crane running on the elevated track, also known as crane. Bridge crane bridge laying along the elevated track in the vertical sides of runs, heavy cart along the laying on the bridge transverse running track, constitute a rectangular scope of work, you can make full use of space below the bridge lifting material, from the ground equipment hindered.
According to the door frame structure
(a) the whole Gantry Crane: the main beam without suspension, the car in the main span of the.
(b) semi Portal Crane: the legs are high or low, can be used in accordance with the requirements of the use of the site.
(c) double cantilever gantry crane: the most common form of structure, the structure of the force and the effective use of the site area are reasonable.
According to the structure of the main beam structure
(a) Single Girder Gantry Crane
Single girder cantilever gantry crane is simple in structure, easy to manufacture and installation, and its own quality is small. 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. Single beam gantry legs to C type and L type two forms of L type of convenient manufacture and installation, good stress condition, its smaller mass, but to lift goods through the legs of the space is relatively small. 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.
(b) double beam bridge crane
Double girder overhead traveling crane is composed of straight rail, crane girder, lifting trolley, power supply system and electrical control system, which is especially suitable for large scale suspension and large range of weight.
Double beam bridge crane bearing capacity is strong, 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.
