Endless Webbing Slings for Heavy Lifting

Name: Endless Webbing Slings
Brand: liftrue
SKU: endless-webbing-slings

KEY FEATURES

Rotatable endless webbing sling for even wear distribution in repetitive basket and choker lifts.

● Wide, Stable Bearing Surface

Flat webbing seats squarely on flat and angular loads — steel plate, pipe bundles, precast units — with no rolling, spreading the load across a wider contact band than a round body.

● Wear Distribution Around the Loop

The continuous loop can be rotated between lifts to distribute wear around the sling body — extending service life in repetitive basket and choker work. Rotation does not replace inspection or retirement requirements.

● High Strength-to-Weight Ratio

High-tenacity polyester provides high strength with low sling weight, supporting easier handling and lower transport weight than comparable steel or chain solutions. The controlled elongation holds the load steady and absorbs shock from dynamic lifts, reducing peak forces on the sling and the load.

● Corrosion & Weather Resistance

Polyester does not rust or corrode, and it resists UV and moisture better than wire-based rigging. This makes it a practical choice for outdoor, marine and washdown duty.

● 1,200+ t/y · OEM / ODM · Standard sizes 3–7 days · Sample orders welcome

SELECTION GUIDE

Which Sling Fits Your Lift?

Your Situation	Best Choice	Why & What to Specify
Step 1 - Material
General-duty lifting between -40 °C and +100 °C - factory, warehouse, precast yard	Polyester sling	Will not rust, and protects finished surfaces. The default choice for most industrial lifts.
Sustained heat above +100 °C, or sharp edges that cannot be padded	Steel wire rope sling	Polyester is rated -40 °C to +100 °C and cuts far more easily than steel. Above that range, or where edges stay sharp, specify wire rope.
Weight-critical or offshore lifts where rigger handling dominates	HMPE sling	About 1/8 the weight of a steel wire rope sling at equal breaking strength - see our HMPE slings for offshore and wind work.
Step 2 - Sling Type
Delicate, polished or irregular loads - castings, mouldings, finished assemblies	Round sling	The round body spreads contact pressure and conforms to shape, with no stitch-line pressure points to mark the load.
Flat, angular or uniform loads - steel plate, pipe bundles, precast units	Webbing sling	The flat face seats squarely and resists rolling, and damage is visible on both faces at inspection.
Tight clearance between the load and the hook	Webbing sling	Flat webbing needs less vertical space than a round sling body of the same capacity.
Step 3 - Construction
Direct connection to hooks, shackles or master links	Eye-and-eye	Reinforced eyes attach straight to hardware with no extra fittings - the usual choice for planned, repeatable lifts.
Basket or choker hitches repeated on the same load type	Endless	Rotate the loop between lifts to spread wear around the full circumference; one sling covers vertical, basket and choker hitches.

1. Single-ply: 7.5 mm polyester webbing. Double-ply: two 7.5 mm plies sewn to a 15 mm composite. Final WLL is established for the complete sling construction, stitching and rated configuration — see the Double Ply tab.
2. Dimensions refer to the standard sling body; the optional additional protective sleeve increases outer dimensions slightly.
3. Longer lengths and higher capacities are engineered to order.

Choose an endless sling when your lift involves basket or choker hitches around smooth, uniform loads (pipes, bars, containers) where rotation between cycles extends sling life. Choose eye-and-eye slings when you need direct attachment to hooks or shackles without wrapping the load, or when the load has sharp edges that would concentrate wear on a specific point.

Endless slings distribute wear across the entire loop and allow rotation between lifts. They are especially good for basket hitches and choker applications where even load distribution matters.

Yes. Pass the sling through itself to form a choker hitch. Capacity is reduced according to the choker factor, which we can confirm for your setup.

EN 1492-1 limits the effective working length (EWL) to a deviation of no more than ±3 % of the nominal length. It is measured with the sling laid flat, using a steel tape or rule graduated in 1 mm increments.

Double-ply uses two layers of webbing for higher capacity at the same width and better resistance to cutting and abrasion; single-ply is lighter and more flexible for general duty. Final WLL is established for the complete construction — pick by WLL and working conditions, not by layer count alone.

EN 1492-1 covers flat webbing slings — slings made from one or more layers of woven polyester webbing in a flat band. EN 1492-2 covers round slings — a continuous load-bearing core of parallel yarn enclosed in a seamless tubular sleeve. Both are synthetic slings, but round slings have a softer, more flexible body that conforms to irregular or delicate loads and protects finished surfaces, while flat webbing slings provide a stable, wide bearing surface ideal for balanced basket or choker hitches. Pick round slings for delicate or oddly shaped loads and flat webbing slings when you want a flat, wide contact area. Custom or project-engineered configurations are subject to separate technical review.

Yes. We can add reinforced protection sleeves or coatings at wear points to extend sling life in abrasive or repeated-lift applications.

Vertical hitch uses 100% of WLL, basket hitch up to 200%, and choker hitch roughly 80% depending on the choker angle. Basket capacity depends on the angle between legs — 200% applies only when the legs run parallel. Always follow EN 1492-1 guidance for your specific setup.

Endless webbing slings have no eyes, so wear spreads around the entire loop — rotate the sling between lifts to distribute wear evenly and inspect the stitched overlap joint carefully for separation or thread pull-out. Withdraw immediately if you see cuts, abrasion, chemical damage, heat marks, missing labels, or any structural deformation.

SAFETY

Endless Webbing Slings - Safety & Usage Guidelines

Even Wear Around Loop

Endless webbing slings have no eyes, so wear spreads around the whole loop — rotate the sling between lifts to distribute it evenly.

Inspect the Splice

Inspect the stitched overlap joint carefully for separation, thread pull-out, or broken stitching — this seam is the highest-stress point on the loop.

Never Exceed WLL

Never exceed the WLL on the identification tag. Endless webbing slings are color-coded by WLL per EN 1492-1 for instant capacity checks.

Apply Hitch Factors

Apply the correct hitch factor: 1.0 × WLL vertical, 0.8 × WLL choker, up to 2.0 × WLL basket — the 2.0 figure applies only when both legs run parallel. Recalculate the effective WLL for the hitch and angle actually used.

Protect the Splice

Keep the stitched seam away from the load contact and from any hook or shackle; never let the seam pass through a choker hitch point.

Pad Sharp Edges

Fit protective sleeves or corner pads on sharp edges — flat webbing is more cut-prone than round slings, so effective edge protection is required whenever sharp or abrasive contact is possible.

Never Tie Knots

Never tie knots. The endless construction makes a knot both unnecessary and damaging for any hitch configuration.

Respect Temperature Range

Keep within −40 °C to +100 °C for polyester, and away from welding arcs, molten splatter, and chemical exposure.

Retire on Damage

Retire immediately on cuts, broken stitching at the overlap, chemical attack, heat marks, missing tags, or any structural deformation.
