桥式起重机和龙门起重机行走部分的主要问题是车轮磨损剧烈,其中包括轮缘的磨损,以及因此而使钢轨头部侧边的磨损。分析表明,采用附加装置的方法,使轮缘对钢轨不产生滑动摩擦,使起重机相对轨道运 The main problems with walking parts of overhead traveling cranes and gantry cranes are severe wheel wear, including wear of the rim, and therefore wear on the sides of the rail head. Analysis shows that the use of additional means to make the flange on the rail does not produce sliding friction, so that the relative orbit crane
