US Webbing sling Synthetic web slings are generally constructed of nylon, or less
frequently, polyester material and offer several attractive
features which promote their popularity among rigging products.
They are often selected when expensive, highly polished, fragile or
delicate loads must be lifted. The softness of the web will not
mar, deface or scratch loads, while its flexibility assures a firm,
secure grip around the item being lifted. The light weight of the
material, combined with superb flexibility allow the slings to be
quickly and safely handled by riggers.
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:
