The truss gantry crane is also known as the road bridge door machine, the road bridge door crane, the road bridge crane, the bridge machine and other names. Why the double girder truss gantry crane can be large-scale used in the road bridge industry, what is truss cranes’ characteristics?
The double main beam bridge door machine is mainly used for road and bridge engineering project beam factory, material field, lifting bridge use. The bridge gantry machine can be divided into single hook door machine and double hook door machine, it can be said that the single-door gantry crane and double-door gantry crane. Stands the gantry crane legs have flower stand legs (with Angle steel, square steel assembled) and circular tube legs two structures, lifting weight without fixed amount, are available according to factories requirements. The double girder truss gantry crane operation mode using bridge operation and a modified remote control this in two ways. The truss crane main point is simple in structure, bridge gantry crane metal structure with pin shaft or flange connection.
The main structure of the truss frame gantry crane consists of nine parts: cart walking, outrigger leg, main girder, lifting trolley, stabilizer bar, balanced beam, operating room and operating room base etc.
Truss gantry crane is easy to transport, install and teardown, the workplace is not demanding, the speed is stable, single girder truss gantry crane hoisting bridges need two door machine while double girder truss gantry crane hoisting bridge can independently but for larger span requirements. The door type crane of the frame structure in the larger sandy place is not easy to collapse due to wind resistance occurred.
That's why double girder truss gantry crane available for large-scale use in the road bridge industry.
