一、啃辺的严重危害桥式吊车普遍存在着轮缘啃咬轨道的问题。由于制造、安装、操作等原因,轨道和吊车纵向中心线经常处于不平行状态,总有个偏斜角β,而且经常变化;所以,歪斜运行,车轮跑偏,是吊车的运行特性。按照现行技术规范允许的偏差,由于车轮跑偏,一端超前量的积累,不出现啃道现象的自由歪斜运行距离一般只有50米左右。据有关调查资料,80％以上的吊车有啃道现象,70％的轮缘和轨道被啃咬磨损。一般说来,通用软
First, the serious danger of eating gnaw bridge crane widespread rift bite orbit problem. Due to manufacturing, installation, operation and other reasons, the longitudinal centerline of the track and the crane are always in a non-parallel state, always having a skew angle β, and often changing. Therefore, the skew operation and the wheel running deviation are the operating characteristics of the crane. In accordance with the current technical specifications allow deviation, due to wheel deviation, one side of the amount of advance accumulation, does not appear to chew the phenomenon of free skew running distance is generally only about 50 meters. According to the survey data, more than 80% of cranes have chewed road, 70% of the rims and tracks were bitten by wear and tear. In general, universal soft
