When using large tonnage lifting belts, it is not difficult to find that its safety factor is less than six times under normal circumstances
This is because when the tonnage of lifting slings exceeds 20 tons, the detection data are theoretical data
Even if the lifting belt manufacturer has carried out tensile test, it is also the static load test of flat lifting belt

The suture of synthetic fiber sling is customized by the manufacturer according to different specifications and models
For example, the suture lines and suture spacing of large tonnage sling are different from those of one ton flat sling
Because the width, thickness and bearing capacity of the two webbing are different, if the same suture data is used, there will be invalid suture
If such sling is used for hoisting, If the bearing force is not broken, it will also break during hoisting, so attention should be paid
Because the circular hoisting belt is used to prevent the hoisting accident caused by excessive load during dynamic load hoisting
The use of 50 ton lifting belt starts from understanding and avoids losses and accidents caused by lack of information
