钢丝绳插编吊索具：
Wire rope insertion sling device:
1、索扣的实际破断强度应至少为相应钢丝绳的最小破断拉力的70%。
1. The actual breaking strength of the cable should be at least 70% of the minimum breaking tension of the corresponding wire rope.
注：如果钢丝绳为金属芯的，则金属芯应至少穿插三次，可以把它看作是钢丝绳的承载部分。
Note: If the wire rope is metal core, the metal core should be inserted at least three times, which can be regarded as the load-bearing part of the wire rope.
2、在单根吊索具中，每一端索扣的插编部分的最小距离不得小于钢丝绳公称直径的10倍。
2. In a single sling, the minimum distance of the insertion part of the cable buckle at each end shall not be less than 10 times the nominal diameter of the wire rope.
压制钢丝绳吊索具：
Compressed wire rope sling:
1、索扣的实际破断强度应至少为相应钢丝绳的最小破断拉力的90%。
1. The actual breaking strength of the cable should be at least 90% of the minimum breaking tension of the corresponding wire rope.
2、压制钢丝绳吊索具的绳套的套长（指接头到绳套内边的距离）在没有套环的情况下，不得小于钢丝绳公称直径的15倍。
2. The sleeve length (the distance between the finger joint and the inside of the sleeve) of the rope sling for pressing the wire rope sling should not be less than 15 times the nominal diameter of the wire rope without the sleeve ring.
