4 tonne Polyester Double Layers Webbing Sling
Endless Lifting Sling
Our polyester webbing slings all meet EN 1492-1:2000, AS 1353.1-1997, JB/T 8521-2007 requirements. We are able to manufacture and supply standard web slings in the format of 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.
Polyester webbing slings are slowly and progressively gaining the market share worldwide because of their unique features. They are a cheaper alternative to the traditional slings that have been used till date.
