3 Tonne Duplex Webbing Sling

Plumalti | 3,000 kg WLL | 90mm Width | Yellow | BS EN 1492-1 | CE Marked | UKCA Compliant

The Plumalti 3 Tonne Duplex Webbing Sling is a heavy-duty lifting sling built for the demands of commercial construction, civil engineering, and heavy manufacturing. Manufactured from 100% high-tenacity polyester to BS EN 1492-1:2000, the 90mm wide yellow-coded sling provides a Working Load Limit of 3,000 kg in a straight lift — rising to 6,000 kg in a basket hitch configuration. The wider 90mm strap distributes the load over a greater bearing area, reducing pressure concentration on both the sling and the load's surface. This makes the 3 tonne sling well suited to lifting structural steel, precast concrete elements, heavy plant components, and multi-pack building materials where load surface protection matters. The dual-layer (duplex) construction provides exceptional abrasion resistance for repeated use in tough site conditions. Each sling is fitted with a blue traceability label displaying the serial number, WLL, length, and mode factors. Available in lengths from 1m to 12m.

Technical Specifications

Mode Factors: Straight lift = 3,000 kg | Choke hitch = 2,400 kg | Basket hitch = 6,000 kg. Always check the blue traceability label before use to confirm the correct mode factor for your lift configuration.

Key Features

• Manufactured to BS EN 1492-1:2000 — produced from 100% high-tenacity polyester, tested and certified to the European harmonised standard for flat woven webbing slings
• Duplex (two-layer) construction — two layers of woven polyester stitched together provide superior strength, durability, and abrasion resistance for repeated use in demanding site conditions
• Yellow colour-coded for 3 Tonne WLL — instant visual identification of Working Load Limit in accordance with the international colour standard, enabling quick sling selection under pressure
• 90mm width for superior load distribution — the wider strap spreads the lifting force over a greater bearing area, reducing localised pressure on both the sling and the load surface
• 6,000 kg capacity in basket hitch — in a basket configuration the effective WLL doubles, giving the 3 tonne sling the capacity to handle heavy structural elements and precast units
• Soft, non-marking polyester — won't scratch, dent, or damage loads during lifting, protecting painted steelwork, cladding panels, architectural elements, and finished surfaces
• 7:1 safety factor — minimum breaking strength of 21,000 kg provides a substantial safety margin for site lifting operations
• Blue traceability label — individually serialised with WLL, length, mode factors, and manufacturer details for full LOLER inspection traceability and audit compliance
• Chemical and UV resistant — polyester resists degradation from most common construction chemicals, oils, and moderate UV exposure, extending working life on site
• Wide temperature range — operates from -40°C to +100°C without loss of performance, suitable for all UK weather conditions and industrial environments

Suitable Applications

The 3 Tonne Duplex Webbing Sling is designed for mid-range to heavy lifting operations where the 2 tonne sling reaches its limit. On construction sites, it handles structural steel beams, precast concrete lintels, heavy timber glulam beams, staircase flights, cladding panels, and multi-pack building materials. Tower crane operations use 3 tonne slings for moving heavy brickwork pallets, concrete block packs, and bagged cement deliveries between floors. In civil engineering and infrastructure, the sling lifts reinforcement cages, concrete pipes, ducting sections, and utility equipment. Manufacturing and heavy engineering operations use it for positioning machinery, large fabricated components, and heavy sub-assemblies. The 90mm width makes it particularly effective for loads that benefit from a wider bearing surface — reducing the risk of the sling cutting into or marking the load under tension.

Webbing Slings vs Chain Slings

1. Surface protection — webbing slings won't scratch, dent, or damage the load. Chain slings can gouge painted surfaces, mark polished metals, and chip concrete edges. If the load's surface condition matters, use webbing.
2. Weight — a 3 tonne webbing sling weighs a fraction of an equivalent chain sling. This reduces manual handling strain when rigging and de-rigging, particularly at height or in confined spaces.
3. Flexibility — webbing conforms to irregular load shapes and spreads the load over the full strap width. Chain concentrates the lifting force at individual link contact points.
4. Inspection — webbing slings are easier to visually inspect for damage. Cuts, fraying, and abrasion are immediately visible. Chain slings require closer inspection for link stretch, cracks, and wear that may not be obvious.
5. Cost — webbing slings are significantly less expensive than chain slings of equivalent capacity. For applications that don't require the heat or chemical resistance of chain, webbing delivers better value.
6. When to use chain instead — chain slings are the better choice for hot loads (above 100°C), chemically aggressive environments, and applications where the sling may contact sharp edges that would cut through webbing.

Certification and Compliance

This product is CE marked in accordance with EU Machinery Directive 2006/42/EEC and is UKCA compliant for the Great Britain market. Manufactured to the performance requirements of BS EN 1492-1:2000 — the European harmonised standard for flat woven webbing slings used in general purpose lifting operations. Each sling is produced with a 7:1 safety factor, individually serialised, and supplied with full traceability documentation including WLL, length, mode factors, and manufacturer identification. All lifting equipment used on UK construction sites must comply with the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER) and the Provision and Use of Work Equipment Regulations 1998 (PUWER). The sling's blue traceability label provides the information required for LOLER thorough examination records.

Safety Information

• Never exceed the rated Working Load Limit (WLL) for the selected hitch configuration. A choke hitch reduces the WLL to 2,400 kg.
• Inspect the sling before every use. Remove from service immediately if cuts, fraying, abrasion, heat damage, chemical contamination, or illegible labelling is found.
• Do not use webbing slings on sharp-edged loads without protective corner sleeves or wear pads — sharp edges can cut through the webbing under load, even at a fraction of the rated WLL.
• Do not knot or twist the sling to shorten it. Knotting reduces the WLL by up to 50% and creates unpredictable failure points.
• In multi-sling lifts, ensure the included angle between sling legs does not exceed 120°. At angles above 90°, the load on each sling increases significantly.
• Do not expose polyester webbing slings to acids, bleaches, or strong alkalis. Polyester is resistant to most common oils and solvents but should not be used in chemically aggressive environments without guidance.
• Never stand under a suspended load. Ensure the lift area is clear of personnel before raising the load.
• A risk assessment and method statement must be in place before any lifting operation. Operation only by competent persons who are trained in sling use and rigging techniques.

Inspection and Maintenance

Webbing slings must be visually inspected before each use and undergo a thorough examination at least every six months (or in accordance with an examination scheme) by a competent person under LOLER 1998. All inspections must be documented and records retained. Look for cuts, tears, or holes in the webbing; abrasion damage or worn fibres exposing the inner layer; broken, cut, or worn stitching; heat damage, melting, or glazing of the polyester surface; chemical contamination, staining, or discolouration; and damage to or illegibility of the traceability label. Pay particular attention to the eye areas and stitching zones where wear is most concentrated. Any sling showing signs of damage must be removed from service immediately. Webbing slings cannot be field-repaired — damaged slings must be cut and disposed of to prevent re-use.
