Endless Web Slings

Endless Web Slings are a continuous loop of webbing with no eyes, fittings, or hardware — formed by joining the ends of the webbing together with a load-bearing splice. Classified as Type 5 under ASME B30.9, they are among the most versatile and economical synthetic sling configurations available.

The continuous loop design allows the sling to be rotated between uses, distributing wear across the entire body rather than concentrating it at fixed bearing points. This simple feature can significantly extend sling service life compared to eye-and-eye configurations. The sling legs can also be spread apart in a basket hitch to improve load balance and stability.

Amick manufactures endless web slings in both nylon and polyester. Nylon provides greater stretch (approximately 8–10% at rated capacity), which helps absorb shock loads. Polyester stretches less (approximately 3%), offering more precise load control and better resistance to acids and bleaching agents. Both materials resist moisture, mildew, and rot, though nylon loses approximately 15% of its rated capacity when wet while polyester does not.

Every Amick endless web sling is built at our Pittsburgh facility with a 5:1 design factor. Custom lengths and widths are available — contact our team to discuss your requirements.

Type

Type 5 (ASME B30.9 / WSTDA). Continuous loop with no eyes or hardware. Available in nylon and polyester, in widths from 1" to 12" and custom lengths.

Applications

Vertical hitches, choker hitches, and basket hitches. Well suited for applications where the sling needs to conform to irregularly shaped loads, where hardware-free rigging is preferred, or where distributing wear through rotation will extend sling life. Common in manufacturing, plant maintenance, construction, and general industrial lifting.

Exceptions

Not recommended for use in environments where temperatures exceed 194°F (90°C) or fall below -40°F (-40°C). Nylon web slings are susceptible to damage from acids and bleaching agents. Polyester web slings are susceptible to damage from strong alkalis. Nylon slings lose approximately 15% of their rated capacity when wet. Do not use on loads with sharp edges unless proper edge protection or wear pads are in place. Remove any web sling from service immediately if it shows visible cuts, fraying, chemical damage, or UV degradation.
