Lifting slings can be divided into flat belts and round belts; during the lifting process, lifting slings have the characteristics of shock absorption, no corrosion, no conductivity, and no sparks in flammable and explosive environments. Its cross-sectional shape changes with the surface shape of the hanging parts, and it is very soft and easy to bend. During work, it will cling to or wrap around the hanging parts without damaging the hanging parts, and at the same time reduce the possibility of rebound and injury; lifting belts have good resistance to corrosion.
Lifting belts are generally used in flammable and explosive environments and do not produce sparks. Since the world's first synthetic fiber flat lifting belt was successfully used in the field of industrial lifting in the United States in 1955, it has been widely used in the fields of shipping, metallurgy, machinery, mining, petroleum, chemical industry, ports, electricity, electronics, transportation and other fields. Lifting belts have excellent characteristics such as light weight, easy maintenance, good chemical resistance, light weight, high strength, and not easy to damage the surface of the hoisted object. It is increasingly favored by users and has gradually replaced wire ropes in many aspects.
The disadvantages of lifting belts are mainly different from wire ropes. The main manifestation is that when the hoisted object has sharp edges, these sharp edges will cause destructive cuts to the lifting belt. In order to protect the lifting belt from cuts, a protective lining can be placed between the lifting belt and the hoisted object.
