3～4米~3挖掘机目前是我国露天煤矿、冶金矿山的重要开采机械。履形座是挖掘机底架梁和履带架之间连接的关键件,装配关系如图1所示。因为受力大,经常损坏,需要修理更换。近几年来,挖掘机制造厂和一些大修厂在实践中探讨和总结了一套较完善的履形座换、装、修新工艺。经过阜新矿务局等单位五年来使用证明比较理想。具体方法为: 3 ~ 4 m ~ 3 excavator is currently China’s opencast coal mine, an important mining machinery. Crossover is the key part of the connection between the excavator chassis girder and the crawler frame, the assembly relationship shown in Figure 1. Because of the force, often damaged, need to repair replacement. In recent years, excavator manufacturing plant and some overhaul plant in practice to explore and summarize a more perfect Crossover replacement, loading, repair new technology. After five years of Fuxin Mining Bureau and other units proved to be ideal. The specific method is:
