How to test the performance of steel wire ropes and riggings

The main content of the inspection is to identify the appearance, twisting quality and internal performance (especially the mechanical performance) of the wire rope sling.

The mechanical property test of steel wire rope sling includes the whole rope test and split strand test, and the samples are intercepted in the stranded steel wire rope sling. The whole rope breaking force test is carried out on the tensile testing machine. According to the specifications of the steel wire rope sling, different clamps are used to fix both ends of the sample, so that the clamp can clamp the sample and apply the force evenly to each strand of the sample. The breaking force of steel wire rope shall meet the standard and be calculated according to the relevant formula. Some special steel wire rope slings should also be subject to fatigue test, rubber adhesion performance test, flatness test, etc.

The inspection of wire rope and rigging is an important guarantee for whether the product meets the quality requirements. Everyone should strictly carry out quality inspection to ensure that the wire rope sling can be used only after it meets the quality standard, which increases the guarantee for safe operation!
