钢丝绳由于自重造成的悬垂现象在臂架类型起重机中很普遍。长期的刮擦、磨损对结构造成严重伤害。设计中通过采取优化结构、设置托辊等方法，减轻钢丝绳悬链的不利影响。在使用时，落实定期检查保养制度就能避免严重的后果。

The wire rope may result in overhang due to its self-weight,which is very common in the cantilever cranes.Long-time scrapping and wear will cause severe damage to the structure.It's designed to reduce the adverse effect of wire rope hanging chain by optimizing the structure and setting up the roller,etc.Regular inspection and maintenance shall be carried out in order to avoid serious consequences.
