Lightweight UHMWPE Endless Loop Flat Webbing Sling

Lift Sling Rigging Co., Ltd manufactures lightweight UHMWPE webbing slings for lifting    heavy loads where sling weight, bulk and cut damage are the limiting factors. The sleeve is flat woven    from ultra-high-molecular-weight polyethylene (UHMWPE / HMPE) yarn — the same fibre family sold    under the Dyneema® and Spectra® brand names — into an endless loop construction.    An equivalent UHMWPE sling weighs about 0.6 times a polyester sling, gives roughlytwice the tensile strength of polyester webbing of the same width, and resists cuts    and abrasion far better.

Why choose a UHMWPE webbing sling?

• About 0.6x the weight of polyester. For the same working load limit a UHMWPE sling is      roughly 40% lighter, so one rigger can carry and position a sling that would otherwise need two.

• About 2x the tensile strength of polyester. The same capacity in a narrower, more      flexible sling — or a much higher working load limit in the same webbing width.

• Better cut and abrasion resistance. The woven UHMWPE sleeve stands up to sharp edges,      steel plate, scrap and rough concrete much better than polyester or nylon webbing.

• Very low water absorption. UHMWPE does not take on water, does not stiffen and does      not rot. Its density is below 1.0, so a dropped sling floats.

• Excellent chemical and UV resistance. It holds up in salt water, oils and most acids      and alkalis, indoors and outdoors.

• Low elongation at working load. Less stored energy and less spring-back, which gives      more precise load control on heavy and awkward lifts.

• Soft and conformable. The flat woven endless loop body moulds itself to the load, so      it grips well and leaves no hard spots or marring on finished surfaces.

UHMWPE webbing compared with polyester and nylon

Construction and design

• Endless loop flat woven webbing sling, type A to EN 1492-1 — a continuous loop with no sewn end fittings or end stops.

• Single layer or double layer flat woven UHMWPE webbing, woven in house on our own shuttle looms.

• Reinforced and heat sealed wear points; optional PU / TPU coating for additional abrasion protection.

• Soft, pliable and low bulk, so it folds into a small package and is easy to stow, carry and inspect.

• Colour coded by working load limit for quick identification on site, plus a sewn on capacity label.

• Safety factor 7:1 — every sling is proof loaded before it leaves the factory.

Standard capacity range

Working load limits above 10 t, intermediate capacities and special lengths are made to order.    Webbing widths in the table are typical references for UHMWPE flat webbing — confirm the exact    width, thickness and mass per metre against our production drawing for your order.

Markings and traceability

Every sling carries a sewn on label with the information needed for safe use and audit, and a woven    colour code for instant identification:

• Working load limit in tonnes and the corresponding colour code.

• Effective length in metres.

• Material — UHMWPE / HMPE.

• Safety factor — 7:1.

• Standard complied with — EN 1492-1.

• Manufacturer name, date of manufacture and a unique traceability number.

• QR code or barcode traceability on request, linked to the test certificate.

Applications for lifting heavy loads

• Steel fabrication and steel plate handling — where cut resistance and low weight both matter.

• Precast concrete and tunnel segments — strong, non marring and easy to place in tight shutters.

• Wind energy — tower sections, nacelles and blades, including work at height where sling weight counts.

• Shipyards and offshore — wet, salty and abrasive environments where polyester ages faster.

• Heavy machinery, dies and moulds — precise, low stretch lifts with little spring-back.

• Rail and locomotive maintenance — lifting bogies, wheelsets and structural assemblies.

• Glass, stone and finished surfaces — a soft sleeve that will not scratch the load.

• Power stations and plant maintenance — where a light sling can be carried to the lift point by hand.

Customisation options

• Working load limit, webbing width and effective length made to your drawing.

• Single or double layer webbing; reinforced or coated wear points.

• Protective sleeves in leather, PU or UHMWPE for sharp edges.

• Your own colour, printed logo and label layout, including customer part numbers.

• Test certificate to EN 1492-1 and a proof load report with every shipment.

Quality control and testing

UHMWPE webbing is woven, sewn and finished in our own workshop in Taizhou, Jiangsu. Every production    batch is checked for webbing width and thickness, weave density, stitch pattern and label content, and    every finished sling is proof loaded before packing. Minimum breaking load is verified on the test bed    and recorded against the sling’s traceability number, so the certificate that ships with the    sling can always be traced back to the batch and the test record.

Frequently asked questions

What is a UHMWPE webbing sling?

It is a flat woven lifting sling made from ultra-high-molecular-weight polyethylene (UHMWPE, also called    HMPE) yarn — the same fibre family sold under the Dyneema® and Spectra® brand names. We    weave it into a flat endless loop sleeve, so the sling has no sewn end fittings and can be used in    vertical, choker and basket hitches.

How much lighter is it than a polyester sling?

About 0.6 times the weight, so roughly 40% lighter for the same working load limit. One operator can    carry and position a UHMWPE sling that would normally need two people.

How much stronger is UHMWPE than polyester?

Approximately twice the tensile strength for the same webbing width. That gives the same capacity in a    narrower and more flexible sling, or a much higher working load limit in the same width.

Are UHMWPE webbing slings cut resistant?

Yes — noticeably better than polyester or nylon, which is why they are used on steel plate,    structural steel, scrap and precast concrete. For very sharp edges we can add a protective sleeve.

What working load limits and lengths can you supply?

Standard capacities from 1 t to 10 t at a 7:1 safety factor, plus higher capacities and custom lengths    and widths to order. Send us the working load limit, effective length and hitch type and we will confirm    the webbing width and colour code.

Does a UHMWPE sling float and does it absorb water?

UHMWPE has very low water absorption and a density below 1.0, so it does not take on water and will    float. It does not stiffen, swell or rot when wet, which suits wet, marine and offshore work.

What temperature can it work at?

Normally about -40 °C to +80 °C. Keep it clear of hot surfaces, weld spatter and open flame, and    use a heat resistant aramid sling where high temperature cannot be avoided.    See our flame resistant aramid webbing sling.

Care, inspection and safe use

• Inspect the sling before every lift: look for cuts, abrasion, broken or pulled yarns, chemical damage, heat damage and a missing or illegible label.

• Protect the sling from sharp edges with a sleeve or a corner protector, and never drag a load over the sling.

• Do not exceed the working load limit, and remember that capacity falls in choker and multi-leg configurations.

• Store clean and dry, out of direct sunlight, away from heat sources and chemicals.

• Wash only with clean water and a mild detergent; never machine wash or tumble dry.

• Retire the sling immediately if the label is missing, if the webbing is cut or badly abraded, or if the sling has been overloaded or shock loaded.

• Keep a written inspection record — our downloads page has a printable inspection sheet.

Request a UHMWPE webbing sling quotation

Tell us the working load limit, effective length, hitch type and the environment the sling will work in,    and we will come back with the right webbing width, colour code, weight and a factory direct price.    Custom lengths, printed logos and test certificates are all part of the service.
