Is the outer sheath of a synthetic endless sling considered part of the sling's strength?

The outer sheath of a synthetic endless sling is not considered part of the sling's strength because the primary load-bearing capability comes from the inner core of the sling. The sheath serves as protection for the core, helping to minimize wear and tear, as well as providing some degree of cut and abrasion resistance; however, it does not contribute to the actual strength rating of the sling itself.

Understanding the construction and function of synthetic slings is essential. While the outer sheath may improve durability and safety by guarding against elements that could damage the core, it is the inner fibers that take on the load when lifting. The strength of a synthetic endless sling is primarily determined by these inner fibers, which are designed to handle the specified weight ratings for safe lifting. Recognizing the role of the sheath as protective rather than load-bearing is key to ensuring safe lifting practices.
