The polyester flat web sling are widely used for overhead lifting, delicate loads, for they feature more stronger, durable and relatively flexible, light weight and won’t scratch or crush your load. So flat web lifting slings are more popular in the construction industry and with ship haulers than steel wire rope slings and chain slings. Perhaps the only significant concern of using synthetic web slings is they are more susceptible to potential damage such as cutting, tearing, abrasion, heat and U.V. degradation than wire rope slings or chain slings. So it is very important to inspect webbing sling regularly, here are some rules you need to know:

1. Shall not be loaded in excess of the rated capacity.
2. Shall not be dragged on the floor or over abrasive surfaces.
3. Shall not be twisted, Shortened, lengthened or tied in knots.
4. Shall not be pulled from under loads that are resting on it.
5. Shall not repair any damaged sling.
6. Shall not be stored in chemically active area, underultraviolet light or near heat.
7. Shall always be protected from sharp edges, sharp cornersor abrasive surfaces.
8. Shall always inspect sling before each use.
9. Shall always be inspected to ensure that the correct sling is being used.
10.Shall always have the load balanced before transporting.
11.Never use slings under -40°C Or more than 100°C.
12.Elongation rate <3% at working load <10% at breaking load.

Synthetic web slings both end can pair with rigging accessories to conjunct with a crane or some type of lifting device, such as hooks, rings or other attachments.
