- When the breaking wire over 10% of total wire in one step, then the wire rope should be changed.
- The wear of diameter of one wire rope reach 7%, operator should change it in any indoor overhead bridge crane using.
- The breaking wire in one wire rope that used to lift heat metal or dangerous goods reach half of service standard, you should change it.
