LOUPS high-modulus endless slings, by Yale Cordage or a Yale Cordage licensee, significantly advance the technology of lifting slings by utilizing a strength-optimizing, multiple-strand endless braid of HMPE fiber encased in a polyethylene abrasion sleeve. They are the most efficient synthetic slings available and far lighter than steel or conventional round slings.
The diameter of the LOUP core and the number of wraps vary by the required tensile strength. Since the strength element is small, this product has a 1.1:1 D/d ratio (or bending radius) for Vertical WL. Simply put, LOUPS are less affected by sharp bending radii than larger ropes of comparable strength.
