The presence of kinks in a wire rope sling is primarily associated with loads that are not equipped with softeners. When a load is dragged or pushed without softeners, there is an increased likelihood that the wire rope will experience uneven tension and localized stress points. This uneven stress can force the wire rope to bend sharply, which leads to kinking.

Softeners are designed to distribute the load more evenly and reduce the risk of sharp bends in the sling, which protects the integrity of the wire rope. Thus, using loads without softeners creates a scenario where kinks are far more likely to develop, compromising the safety and effectiveness of the sling. Therefore, recognizing the importance of load protection features like softeners is crucial for maintaining the operational integrity of wire rope slings.
