10 tonne Double Layers Endless Webbing Sling, Polyester Lifting Sling, for Heavy Lifting Applications
Duplex Endless Lifting Sling, Flat Webbing
Polyester webbing slings are much cheaper than alternatives made from other materials and usually are lighter, more flexible and have a greater factor of safety, though they do have less abrasive resistance.
Our polyester webbing slings can be manufactured and supplied in the standard web sling format: Endless, Single layer, Double layers, or to a custom design.
Duplex webbing slings are manufactured from high tenacity polyester webbing which is colour-coded for easy identification during lifting. Duplex slings are crafted from double layers of webbing that either terminates in a metal end-setting or generally sewn back upon themselves with an extreme tenacity polyester fabric to frame a reinforced “Eye” that has much better durability as compared to the traditional leather eye.
The duplex webbing slings are generally stitched near the eyes. However, the endless slings are made from single thick webbing, sewn in an uninterrupted loop with an overlap. These slings are popular type and are suitable for general and heavy lifting, as they are as strong as steel and are yet very light.
In order to guard the webbing from unnecessary wear and tear, several coverings are available, in any length, which protects both the sling and fragile loads.
