2Ton Endless Webbing Sling - green WLL band with 2 black capacity stripes on 50 mm webbing

1. What Is a 2Ton Endless Webbing Sling?

An endless webbing sling — Type A in EN 1492-1 — is a flat woven synthetic sling formed as a continuous loop: a length of webbing is lapped back over itself and stitched to close the loop. There are no eyes to hook and no fittings to lose.

One point about the loop needs stating plainly, because it is widely mis-sold. An endless sling is often described as seamless, as having no joints and no weak points. That is not accurate. An endless sling is closed by a stitched lap splice — that is how the loop is made. What the design actually gives you is three real advantages:

• The joint is a long overlap, not a short eye. The splice runs along the webbing at an overlap, instead of being concentrated into a reinforced eye that takes the whole hook load in a small area.

• The loop can be rotated. After each lift the sling can be turned so that no single section — splice, hook contact point or bearing area — accumulates all the wear.

• The whole circumference is usable bearing area. There is no fixed eye position, so the sling can be positioned wherever the load and the hook require.

Where the 2 tonne band sits, and what makes this page different from its siblings. The 2 t band is the smallest standardised band in the range and it is almost never used on its own: it is the band that goes out in pairs and triples on small assemblies, and the band whose colour is the most commonly misread in the whole scheme. So this page concentrates on the three questions that actually decide whether a 2 t pick is safe:

• Green webbing or a green label? The same word means two unrelated things on the same sling (section 2).

• Two slings, three slings or four — what does the assembly carry, and which leg takes what? (sections 4 and 5)

• How long should the slings be? Because choosing a shorter sling quietly reduces the capacity (section 6).

The underlying hitch ratings are in section 3, and the full technical data is in section 7.

2. Green Webbing or a Green Label?

Green is the single most misread colour in the EN 1492-1 scheme, because it carries two completely different meanings depending on whether you are looking at the webbing or at the label.

The short version. Green webbing tells you the band: 2 tonnes. Green label tells you the fibre: polyamide, also called nylon. The two are independent, and a single sling can be green-webbed with a blue label (2 t polyester) or green-labelled on webbing of any colour (nylon of some other band).

What to do about it. Order by capacity, fibre and length, not by colour. Then check three things on delivery: the webbing colour (green for the 2 t band), the stripe count (two), and the label colour and text (which must state the working load limit and the material). The full EN 1492-1 colour code, from 1 t (violet) to 10 t (orange), is set out on the 8 ton endless webbing sling page.

3. The 2 t Sling in Every Hitch

The figure on the colour and on the label is the straight-lift figure. The figure you compare with your load is that rating multiplied by the mode factor of the hitch you are using:

The choked figure is what governs most 2 t work. A 2 t sling is 1.6 t the moment you choke it, and 1.6 t is reached quickly by small assemblies — a motor on a frame, a crate, a bundle of box section. Two consequences:

• A 1.8 t crate cannot be choked on a 2 t sling. Take it in a basket, split it, or step up to the 3 t band, which gives 2.4 t choked.

• A choke at 45° drops the 2 t band to 1.4 t. Where the sling is choked and the legs then open away from vertical, the rating falls again, so a pick planned at 1.6 t may be outside the rating once the legs open.

This table covers one sling on its own. When two or more slings are used together as a matched assembly, a different set of factors applies and the questions become “what does the assembly carry” and “which leg takes what” — those are sections 4 and 5.

4. Two-Leg and Multi-Leg Picks on the 2 t Band

Two-tonne slings are usually bought in pairs or in fours, because that is how they are used: on a two-point pick, on a four-corner pick, or on a small spreader. When slings are used together as an assembly, the rating is no longer the single-sling rating multiplied by the number of legs — the standard applies a factor that already accounts for both the number of legs and the angle they open to.

Three things to take from that table.

• A two-leg assembly of two 2 t slings is a 2.8 t assembly, not a 4 t one. That holds only while the legs stay within 45° of vertical. Add any real angle and most of the benefit is gone. The capacity figures are modest, and this is the most common over-estimate made with small slings.

• A four-leg assembly is rated as if only three legs carry the load. That is what the 2.1 factor already assumes, and it is deliberate: four legs cannot be relied on to share a load equally. So four 2 t slings give 4.2 t, not 8 t.

• Angle is the multiplier. Both the 2-leg and the multi-leg rows lose close to a third of their capacity when the legs open past 45° from vertical. Keep the legs steep and the assembly keeps its rating.

5. When the Load Is Not Centred: Load Share Between Two Pick Points

This is the most common failure mode on a two-point pick, and it does not show up in any capacity table. If the centre of gravity is not halfway between the two pick points, the two slings do not share the load equally — and the one nearer the centre of gravity takes more.

Worked consequence. Three tonnes picked on two 2 t slings. If the centre of gravity is halfway, each sling carries 1.5 t and both are comfortable. Move the centre of gravity a third of the way towards one end and that sling now carries 2.0 t — its full rated load, with nothing left for the on-site changes that always happen. Move it a quarter of the way and it carries 2.25 t — an overload on a pick whose total, 3 t, looked well within two 2 t slings.

What to do about it. Position the pick points so the centre of gravity sits between them and as close to the middle as the load allows; weigh or calculate the offset rather than judging it by eye; and where the load genuinely cannot be balanced, use a lifting beam, which takes the offset into the beam rather than into one leg of the sling. A beam is usually cheaper than the consequences of an unbalanced pick.

6. Leg Length and the Angle You Get

The angle a sling opens to is not chosen from a table — it follows from the spacing of the pick points and the length of the sling. Choose a shorter sling to gain headroom and the legs open wider, which reduces the capacity. That relationship is easy to see with a fixed example: pick points 2 m apart, so each leg spans 1 m horizontally from the hook.

The counter-intuitive part. Buying a shorter sling feels like buying a more compact, more controllable sling. In a two-leg pick it does the opposite: shorter legs mean a wider angle, a lower assembly factor, and more squeezing force into the load. The 2 m legs in the first row and the 1.2 m legs in the third row are the same slings, at the same pick points, holding the same load — and one of them is nearly 30% weaker as an assembly.

Three practical conclusions.

• Choose length from the pick height, then check the angle — not the other way round.

• If you need headroom and the legs are going to be steep, use a beam. A lifting beam with adjustable hooks keeps the legs vertical and passes the spread through the beam instead of through the legs.

• Re-check the angle at the height the load will travel, not only at the ground: a pick can be inside the limit when it lifts and outside it when the hook rises.

7. Technical Specifications

Reading that table. The 14 t minimum breaking load is a destruction figure derived from the 7:1 factor — it is not a working capacity and must never be used as one. The elongation figures describe what polyester does under load: 3% or less at the working load, up to 10% at the breaking load.

The same 2 t sling is a different object under a different standard. At the EN 1492-1 factor of 7:1 it must survive 14 t. Under ASME B30.9, where the design factor for these slings is commonly 5:1, a 2 t rating corresponds to 10 t. Under AS 1353 at 8:1 it corresponds to 16 t. Three slings, all marked 2 t, all built to a materially different margin — which is why the standard reference on the label matters as much as the number beside it.

8. Applications

Four habits that get the most out of a 2 t band:

• Rotate the loop between lifts. The endless design lets you move the wear point, the splice and the hook contact point around the webbing; if the same section always sits in the hook, the endless sling wears no better than an eye-to-eye sling.

• Balance the pick. A two-point pick with an off-centre load is the most common way a 2 t sling gets overloaded while the total looks fine.

• Keep the legs steep. Every degree the legs open past vertical costs capacity, and past 45° the loss is a third.

• Plan the pick around 1.6 t, not 2 t. The 2 t band's usable choked capacity is 1.6 t, and a method statement written around the headline 2 t is the one that overloads the sling.

9. Inspection, Care and Retirement

Care rules:

• Never use a polyester webbing sling below −40 °C or above +100 °C.

• Do not drag the sling on the floor or across abrasive surfaces, and never pull it out from under a load resting on it.

• Do not twist, knot, shorten or lengthen a sling, and never repair one. Repairing a stitched lap splice is not possible on site.

• Clean with mild soap and water and dry naturally; do not machine dry or heat dry.

• Store dry, dark and off the floor, away from oil, chemicals and sharp edges.

• Inspect before every use, and record a documented periodic inspection. In an assembly, inspect every sling in the set, and keep sets together.

A sling should be cut through before disposal so that it cannot be put back into service by mistake.
