10 Tonne Duplex Webbing Sling

Plumalti | 10,000 kg WLL | 300mm Width | Orange | BS EN 1492-1 | CE Marked | UKCA Compliant

The Plumalti 10 Tonne Duplex Webbing Sling is a heavy-duty flat lifting sling manufactured from 100% high-tenacity polyester to BS EN 1492-1:2000. The 300mm wide orange-coded sling provides a Working Load Limit of 10,000 kg in a straight lift, rising to 20,000 kg in a basket hitch, with dual-layer (duplex) construction for outstanding strength and abrasion resistance. Each sling carries a blue traceability label and is available in lengths from 3m to 10m.

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 demanding lifting operations
• Orange colour-coded for 10 Tonne WLL — instant visual identification of Working Load Limit in accordance with the international colour standard
• 300mm width — distributes the lifting force over a wide bearing area, reducing localised pressure on both the sling and the load surface
• 20,000 kg capacity in basket hitch — in a basket configuration the effective WLL doubles, providing additional versatility for heavier loads
• 70,000 kg minimum breaking strength — the 7:1 safety factor provides an exceptional margin for site lifting operations
• Soft, non-marking polyester — won't scratch, dent, or damage loads during lifting, protecting painted surfaces, cladding, and finished goods
• Blue traceability label — individually serialised with WLL, length, mode factors, and manufacturer details for full LOLER inspection traceability
• Low elongation (max 3%) — predictable load behaviour under tension with minimal stretch for controlled positioning
• Temperature range -40°C to +100°C — suitable for all UK weather conditions and standard industrial environments

Technical Specifications

Mode Factors:
Straight lift = 10,000 kg | Choke hitch = 8,000 kg | Basket hitch = 20,000 kg. Always check the blue traceability label before use to confirm the correct mode factor for your lift configuration.

More About This Product

The Plumalti 10 Tonne Duplex Webbing Sling is a heavy-duty flat lifting sling manufactured from 100% high-tenacity polyester to BS EN 1492-1:2000. The 300mm wide orange-coded sling provides a Working Load Limit of 10,000 kg in a straight lift — rising to 20,000 kg in a basket hitch configuration. The dual-layer (duplex) construction delivers outstanding strength, durability, and abrasion resistance for demanding commercial and industrial lifting operations. The soft polyester material protects finished surfaces, painted goods, and delicate loads from scratching or damage during handling. Orange colour-coded for instant WLL identification in accordance with the international colour standard. Each sling is fitted with a blue traceability label displaying the serial number, WLL, length, and mode factors for straight lift, choke, and basket configurations. Available in lengths from 3m to 10m.

Selecting Slings for Tower Crane Operations

1. Match sling capacity to crane chart — the crane's safe working load at the required radius must exceed the total rigged weight, including the sling's own weight, shackles, lifting beams, and any other below-hook equipment.
2. Account for wind loading — tower cranes operate at height where wind forces are significantly greater than at ground level. Wind loading adds lateral force to the sling, increasing the effective load. Follow the site wind speed limits and reduce sling loading accordingly.
3. Minimise sling exposure time — at 10 tonne capacity, loads are typically large structural elements that act as sails in wind. Plan lifts to minimise the time the load is suspended at height. Avoid lifting in gusting conditions.
4. Use colour coding for quick identification — this 10 tonne sling is orange. On a tower crane operation where multiple sling capacities are in use, colour coding allows the slinger to instantly verify the correct sling is being used without climbing to read labels at height.
5. Inspection after each heavy lift — at or near maximum capacity, inspect the sling after each use for signs of overloading: distorted eyes, compressed or glazed webbing at contact points, stretched or loosened stitching, and any cuts from edge contact.
6. Storage between lifts — never leave 10 tonne slings on the ground between lifts. The wide 300mm strap picks up gravel, concrete debris, and sharp fragments that cause abrasion damage on the next lift. Hang on the crane hook or a designated rack.

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).

Safety Information

• Never exceed the rated Working Load Limit (WLL) for the selected hitch configuration. A choke hitch reduces the WLL to 8,000 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.
• 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°.
• Do not expose polyester webbing slings to acids, bleaches, or strong alkalis.
• Never stand under a suspended load. Ensure the lift area is clear of personnel before raising the load.
• A risk assessment must be in place before any lifting operation. Operation only by competent persons 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. Key inspection points include: cuts or tears in the webbing, abrasion damage or worn fibres, broken or damaged stitching, heat damage or melting, chemical contamination or staining, and legibility of the traceability label. 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.
