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.
