Crane beam is the subgrade support girder vehicle running

Crane beam is the subgrade support girder vehicle running, used in steel structure factory building. Crane rail crane beam, truss car by driving back and forth on the crane beam orbit. Like steel crane beam, the difference between crane beam web plate welding with steel crane plate, provide support for lift girder car lifting heavy objects. Welding crane beam flange plate of the appropriate USES a layer of steel plate, when two layers of steel plate is used, the outer plate should be along the long Liang Tong Settings, and in the design and construction sino hoist should be taken to make the top flange closely contact with two layers of steel plate. Supporting clamp or rigid material rake hard hook crane and similar structure, truss and brake truss crane is unfavorable use. Crane Liang Yi flange or web of welding arc plates with stitching should be adopted and lead plate, penetration butt weld arc plate and lead plate cutting place should be polished smooth. Crane beam welding and welding construction crane truss segment splicing welding should be adopted or friction type high strength bolt connection.
