Endless webbing slings is also often known as a one way disposable sling and one way lifting sling. It has high tenacity load rating can easily lift heavy duty equipment, feature endless grommet shape which can be able to turn the sling around to share the wear and tear at lifting points. This type of flat webbing sling is ideal for lifting and transporting such as raising yachts, boats and barges into dry dock for maintenance or to be moved to a different location and moving the construction industry and ship haulers, roof trusses and timber, housing panels and walls. Endless webbing sling will stay in position throughout the operation until it is off-loaded at its final destination where it is usually removed. 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.

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.
