The detection before the rope mainly refers to the damage detection, the purpose is to ensure the safety of the wire rope rope. The test items include wire diameter, diameter and breaking force of the wire rope. The test is to check whether the physical and mechanical properties of the new rope meet the requirements of use, and then calculate the safety factor according to the test results to see if it can reach the specified safety factor.

The safety factor of wire rope is an important safety technical index to measure the safety performance and safety status of hoisting wire rope. In order to ensure the safe use of wire ropes, when selecting and using wire ropes, it is necessary to ensure that the safety factor is not less than the lower value specified in the Regulations.
