The reason why flexible lifting belts can be used for lifting large wind turbine equipment is mainly due to their extremely high strength. A qualified flexible lifting belt can have a safety factor of up to 6 times, which means that if the rated load of a flexible lifting belt is 20 tons, its breaking force can reach 120 tons. So what gives flexible lifting belts such strong load capacity?
The strong load capacity of flexible lifting belts is mainly related to their internal structure. Many people do not fully understand the internal structure of some large-sized flexible lifting belts. The internal structure of flexible lifting belts is composed of 24 or 48 high-strength polyester fibers arranged in an infinite and equal manner, forming a closed load-bearing core. Single strand fibers are twisted, and the number of fibers in a row reaches more than 100000 cycles, playing a load-bearing role. Only in this way can the load-bearing core be made to meet the load requirements.
This is the main reason why flexible lifting belts have such strong load capacity. If you want to learn more about flexible lifting belts, you can always follow us.
