How to conduct a tensile test on the wire rope of a winch

The steel wire rope is one of the important components of the winch. The winch achieves heavy lifting and traction operations by winding the drum with the steel wire rope. The steel wire rope is very important for the winch. The quality of steel wire rope is directly related to the safety of the later use of the winch. How is the steel wire rope subjected to tensile testing.

In order to ensure the quality of the steel wire rope, a tensile test must be conducted on the steel wire rope. Steel wire ropes can only be put on the market after undergoing tensile testing. The commonly used methods for tensile testing of steel wire ropes are pouring testing and winding testing.

Pouring test method. First, pour the test steel wire rope with molten metal, then let it cool to room temperature and place it on the clamp seat of the testing machine for tensile testing. However, one may wonder why testing is not carried out directly instead of waiting for it to cool down before testing? This is to ensure the accuracy of the experiment. After the steel wire rope is just produced, its rope body is relatively fragile, which can easily affect the accuracy of the test.

The winding test method places the test specimen in the jaws of the testing machine. During the placement process, it is important to ensure that the product is tightly attached to the testing machine and maintain its winding state. Although it is still impossible to change the position of the tangent point and the bending composite force caused by the test. But the accuracy is very high, and it ensures the seriousness of the test results, making them meet the testing standards. However, the drawback is that it has not yet had any impact on the steel wire rope product, and it cannot be guaranteed that the steel wire rope will break.

The steel wire rope can only be put into the market after completing the tensile test and confirming that there are no problems. If there are any abnormal situations during the test, it will be considered as an unqualified product and cannot be put into the market for sale.
