Should you pay attention to those relevant points when selecting slings?
1, wire rope can be connected or snapped. When selecting wire ropes, the length of splicing should be >15 times the rope diameter and ≥300mm, the connection strength ≥ 75% of the tensile strength, and the distance between the card-snailing ropes should be ≥6 times the rope diameter, and the pressure plate should be on the side of the main rope. There are three string cards with a diameter of 7 to 18 mm, four string cards of 19 to 27 mm, and five string cards of 28 to 37 mm.
2, ordinary hemp rope and white rope. Commonly used for lighter weight items tied and hoisted. No overloading is allowed during use. Broken stocks, cuts, and abrasions should be scrapped.
3, nylon rope. It has the advantages of softness, light weight, corrosion resistance and high strength. Nylon rope allows tension P = 20d2(N). When lifting, keep away from fire and prevent sun exposure. Angular objects should be well cushioned. The shrinkage is large and it should be prevented from hurting people after fracture.
4, the chain. One of the following conditions of the chain should be scrapped: cracks; plastic deformation, elongation of 5% of the original length; wear of the link diameter up to 10% of the original diameter.
5, other slings. The spreader can refer to the scrapping standards of the hook and the chain, focusing on checking for cracks, plastic deformation and excessive wear. The rigging mainly checks for wear or corrosion, severe deformation, broken strands, broken wires or excessive standards.
