钢丝绳吊索的报废标准 Scrap standard for wire rope sling 　　钢丝绳吊索当出现下列情况之一时，应停止使用、修复或报废： In case of any of the following circumstances, the wire rope suspension cable shall cease to be used, repaired or scrapped: 　　1、钢丝绳断1股，或表面钢丝磨蚀达钢丝直径的40%以上，或钢丝绳直径减少7%以上。 1, the steel wire rope breaks 1 share, or the surface wire abrasion of the steel wire is more than 40% of the diameter of the wire, or the diameter of the wire rope is less than 7 percent. 　　2、钢丝绳发生扭结变形。 The wire rope is twisted and twisted. 　　3、钢丝绳在一个捻距内断丝超标：(1)当断丝现象集中发生于局部，在长度为6倍直径的一段内断丝发生在一股上时，达到规定断丝数的一半即应报废。(2)钢丝绳有锈蚀或磨损时，报废断丝数应乘以折减系数。 3, within a length of lay wire rope broken wires to exceed bid: (1) when the concentration occurs in local, broken wires in length is 6 times the diameter of a broken wires in a occurs, reach regulation is half the number of broken wires should be scrapped. (2) when the wire rope has rust or wear, the number of scrap broken shall be multiplied by the discount factor. 　　4、钢丝绳局部可见断丝损坏(有三根以上的断丝聚集在一起)。 The wire rope is partially visible broken wire (with three broken threads together). 　　5、索眼表面出现断丝，或断丝集中在金属套管、插接处附近、插接连接绳股中。 The appearance of a broken thread on the surface of the cable, or the broken wire is concentrated in the metal casing, near the plug, and in the joint. 　　6、钢丝绳由于带电燃弧引起的钢丝绳烧熔、熔融金属液浸烫，或长时间暴露于高温环境中引起的强度下降。 The steel wire rope is caused by the burning of the electric arc, the molten metal liquid is burned, or the intensity of the prolonged exposure to the high temperature is decreased. 　　7、插接处严重受挤压、磨损;金属套管损坏(如裂纹、严重变形、腐蚀)或直径缩小到原直径的95%。 The joints are badly crushed and worn; Damage of metal casing (such as crack, severe deformation, corrosion) or diameter to 95 percent of the original diameter. 　　8、绳端固定连接的金属套管或插接连接部分滑 A metal casing that is attached to a rope end or a part of a plug connection
