桥式起重机已在各类机械制造、冶金、化工等行业得到广泛使用。其小车运行轨道一般都是由制造厂家直接敷设,借用钢轨压板焊在起重机箱形主梁上。但是由于起重机使用频率不同,工作制度不一,一些起重视经常发生小车切边、啃轨、小车轨道松动等现象。同时,某些有特殊要求的桥式起重机,要求上拱度减到最小。如我厂铸钢车间浇铸大型、精细铸件的起重机,吊运钢包时小车容易滑行。为了解决上述问题,我们对多台 Bridge crane in various types of machinery manufacturing, metallurgy, chemical industry is widely used. The trolley running track is generally laid directly by the manufacturer, borrow rail pressure plate welded to the crane box girder. However, due to the different frequency of use of cranes, the work system is different, some car owners often pay attention to trimming, gnawing rails, trolley tracks loose and so on. At the same time, some overhead cranes with special requirements require that the camber be minimized. As I plant cast steel plant casting large, fine castings cranes, trolleys, trolley easy to taxi. In order to solve the above problems, we have more than one
