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

CE Marked, UKCA Compliant & BS EN 1492-1 Certified
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 with a 7:1 safety factor — the minimum breaking strength is seven times the stated Working Load Limit. Each sling is individually serialised and supplied with full traceability documentation. Following Brexit, the UK government has confirmed indefinite recognition of CE marking for lifting equipment in Great Britain, meaning businesses can use either UKCA or CE marked accessories provided the equipment is accompanied by a Declaration of Conformity (DoC).
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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
Sling type is chosen by what the load will do to it: chain tolerates heat and sharp edges, webbing is lighter and kinder to finished surfaces. Rated capacity assumes the angle on the tag — see also shackles and chain and fittings for the connections.
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.
Frequently Asked Questions
Q: What colour is a 10 tonne webbing sling?
Orange. Under BS EN 1492-1, orange indicates 10 tonnes and above. The bright colour provides good visibility on site, particularly useful for identifying heavy-rated slings that must only be used on appropriate loads.
Q: How wide is a 10 tonne duplex sling?
The 10 tonne duplex sling is 300mm wide — the widest in the standard range. This distributes the lifting force over a very wide bearing area, which is essential at these loads to prevent the sling from cutting into or marking the load.
Q: What is the breaking strength of a 10 tonne sling?
With a 7:1 safety factor, the minimum breaking strength is 70,000 kg (70 tonnes). This substantial margin accounts for dynamic loading from wind, sudden stops, and swinging loads that are common on tower crane operations.
Q: Do I need a lifting plan for 10 tonne lifts?
For routine lifts of known loads, a generic risk assessment and method statement is usually sufficient. For non-routine, complex, or tandem lifts at this capacity, a formal lifting plan should be prepared by the Appointed Person in accordance with BS 7121.
Q: Can a 10 tonne sling lift 20 tonnes in basket hitch?
Yes. In a basket hitch configuration, the effective WLL doubles to 20,000 kg. This assumes a symmetrical load with equal weight distribution on both legs and a sling angle not exceeding 120°. Always verify the mode factor on the traceability label.
Q: What lengths are available?
The 10 tonne duplex webbing sling is available in lengths of 3m, 4m, 5m, 6m, 8m, and 10m. For longer requirements at this capacity, round slings may offer additional options.
Q: Are these slings suitable for precast concrete?
Yes. The soft polyester material protects exposed concrete surfaces from chain marks and wire rope scoring. Use protective wear sleeves at contact points with rough or textured concrete to prevent abrasion damage to the sling.
Q: What dynamic factors should I apply?
At 10 tonne capacity, dynamic forces from wind, sudden stops, and swinging are significant. A dynamic factor of 1.1 to 1.3 should be applied depending on conditions. Consult the Appointed Person for guidance on your specific application.
