Web slings have the ability to elongate, absorbing and minimizing the effects of heavy shock loads. Nylon slings may stretch 6-8% at rated capacity, while polyester slings limit stretch to approximately 3% under similar circumstances. Long life cycles may be experienced since synthetic web is unaffected by moisture, mildew, rot and certain chemicals. Polyester should be used in the presence of acids and nylon should be used where alkalis exist.
Synthetic web slings are manufactured from light or heavy duty material that has been surface "treated" to improve abrasion resistance, seal out moisture, and prevent grit from penetrating the web and causing internal wear. Slings can be fabricated from single or multiple plies, may include accessories such as edgeguard, wear pads or sleeves, and are available in several configurations:
