Why do endless slings tend to deteriorate faster than other types of slings?

Endless slings often experience faster deterioration due to the presence of sharp bends. When slings are subjected to sharp bends, the material is forced into a tighter radius than intended, which can compromise its structural integrity. This excessive loading can create localized stress points, leading to fraying, wear, and even failure. The design of endless slings means they may frequently encounter situations where they must bend around corners or other objects, which increases the likelihood of encountering sharp bends and accelerates wear.

While the other factors listed, such as countless bends, double bends, and quick bends, can certainly impact slings in various ways, it is the sharp bends that typically create the most significant risk for damage. These types of bends are particularly detrimental because they can cause severe stress and strain on the sling fibers, leading to premature retirement of the sling from service. Understanding this helps in taking precautionary measures to extend the life of endless slings during rigging and lifting operations.
