It is increasingly favored by users and has gradually replaced wire rope slings in many aspects. While being used for port lifting, it is also widely used in shipbuilding, metallurgy, machinery, mining, petroleum, chemical industry, electricity, electronics, transportation, military and other fields.
[0003] Previously, when the port was carrying out cold-rolled steel coil lifting operations, the slings used were traditional double-buckle slings. Although they had four layers of reinforcement, the slings were made of synthetic fibers and were easily worn. In particular, the contact between the sling and the corner of the cold coil was easily damaged by friction with the outer steel ring of the cold coil, which greatly reduced the service life of the sling and increased the risk of lifting operations. This paper aims to propose an improved sling that is wear-resistant. Utility Model Content
