EN 1492-1 Certified Safety Factor 7:1 WLL 1–30 Tons Eye & Eye China Lifute Sling Group manufactures polyester webbing slings, polyester web slings and polyester flat webbing slings. Heavy-duty flat woven slings with duplex, triplex & quadplex ply options, soft reinforced eyes, color-coded labels and 100% proof-load testing. Competitive wholesale pricing with fast global delivery. |
The polyester webbing sling — also referred to as a flat webbing sling, polyester lifting strap, synthetic web sling or eye & eye sling — is a high-strength, lightweight lifting device engineered from 100% high-tenacity polyester filament yarns woven into a flat, durable webbing construction. Unlike a round sling, the flat profile provides a wider load-bearing surface, making polyester webbing slings ideal for handling sharp-edged, flat-surfaced or finished loads where surface protection and stability are critical.
Our polyester webbing slings comply with EN 1492-1 (European Standard for flat woven webbing slings) and ASME B30.9, and are manufactured under a certified quality management system. Each sling is 100% proof-load tested at 2× its rated WLL and supplied with an individual serial-numbered test certificate, ensuring full traceability from raw material to final delivery.
Available in single-ply, duplex (2-ply), triplex (3-ply) and quadplex (4-ply) constructions with Working Load Limits from 1,000 kg to 30,000 kg (1 to 30 tons). Reinforced soft-eye loops at both ends provide secure attachment to crane hooks, shackles and lifting points without metal-to-load contact damage.
Low Elongation100% high-tenacity polyester webbing — elongation ≤3% at WLL, minimal stretch under load.
Even Load DistributionFlat woven profile spreads load pressure evenly — ideal for delicate, painted or polished surfaces.
Soft Reinforced EyesNo metal hardware at the ends — eliminates surface marring and spark risk.
Multi-Ply Options1 to 4 layers (single / duplex / triplex / quadplex) — optimal strength-to-flexibility ratio.
Color-Coded LabelsEN 1492-1 identification for instant, error-free WLL recognition at the worksite.
7:1 Safety FactorStandard, exceeds minimum regulatory requirements for general-purpose lifting.
Chemical ResistanceExcellent resistance to oils, greases, most acids and alkalis found on job sites.
Wide Temperature Range-40°C to +100°C without load derating; UV-stabilized for outdoor service.
LightweightUp to 80% lighter than equivalent-capacity chain or wire rope slings.
Traceable & TestedSerial-numbered label with CE marking, WLL, length and mfg. date; 100% proof-load tested at 2× WLL.

Polyester webbing slings support three standard hitch configurations. The effective WLL depends on the hitch type — always apply the correct load factor when planning a lift.
| Hitch Type | Load Factor | Eff. WLL (1T Sling) | Application Notes |
|---|---|---|---|
| Vertical (Straight) | 1.0 × WLL | 1,000 kg | Single-leg straight lift; sling vertical, load suspended directly below hook. |
| Choker Hitch | 0.8 × WLL | 800 kg | Sling wrapped around load, one eye passed through the other; choker angle ≤120°. |
| Basket Hitch (0°) | 2.0 × WLL | 2,000 kg | Both eyes on hook, sling cradles load; maximum capacity configuration, load must be balanced. |
| Basket Hitch (0–45°) | 1.4 × WLL | 1,400 kg | Two-leg basket with angle up to 45° from vertical; use spreader bar when possible. |
| Basket Hitch (45–60°) | 1.0 × WLL | 1,000 kg | Maximum basket angle 60° from vertical — do not exceed. |
| 2-Leg Bridle (0–45°) | 1.4 × WLL | 1,400 kg | Two independent slings on a master link; angle measured at the apex. |
| 2-Leg Bridle (45–60°) | 1.0 × WLL | 1,000 kg | Wider spread arrangement; verify sling length symmetry. |
WARNING: Always derate the WLL according to hitch type and angle. Choker angle must not exceed 120°. Basket/bridle angle must not exceed 60° from vertical. Never exceed rated capacity.
Multi-ply constructions balance strength, flexibility and cost. Choosing the correct ply ensures safe, efficient lifting without unnecessary bulk or expense.
| Ply | Typical WLL Range | Best Suited For |
|---|---|---|
| Single-Ply | 500 – 3,000 kg | Light-duty lifting, strapping, bundling, one-time-use applications. Maximum flexibility, lowest cost. |
| Duplex (2-Ply) | 1,000 – 10,000 kg | General-purpose construction, manufacturing, warehouse and logistics lifting. Optimal strength-to-flexibility balance. |
| Triplex (3-Ply) | 8,000 – 15,000 kg | Heavy industrial lifting, steel fabrication, precast concrete and pipe handling. Higher WLL with manageable flexibility. |
| Quadplex (4-Ply) | 15,000 – 30,000 kg | Extreme heavy-duty lifting, offshore and marine applications, wind turbine erection, heavy machinery installation. |
Polyester webbing slings are among the most widely used synthetic lifting devices across global industry sectors, wherever chain or wire rope slings are unsuitable.
Construction & Civil Engineering — steel beams, precast panels, rebar cages and formwork systems.
Steel Fabrication & Metalworking — plate steel, structural sections, pipes and coils without surface damage.
Marine, Offshore & Shipbuilding — shipyard lifting, dock-side cargo handling, barge loading and platform supply.
Oil, Gas & Petrochemical — pipe string handling, valve and flange installation, drilling equipment lifts.
Wind Energy — tower section, nacelle and blade handling during turbine assembly and maintenance.
Manufacturing & Assembly — production line handling, machine positioning, heavy component transfer.
Logistics, Warehousing & Transport — container loading, truck bed securing, palletized cargo.
Power Generation — generator stator and rotor lifts, transformer handling, substation equipment installation.
Automotive & Rail — vehicle body and chassis lifting, engine and transmission rigging.
Mining & Quarrying — equipment maintenance lifts, crusher component handling, conveyor installation.
Examine the full webbing length for cuts, tears, abrasion or broken stitching on body and eye loops.
Check for chemical attack indicators — discoloration, stiffening or surface flaking of the fibers.
Inspect for heat or friction damage — melting, glazing, charring or fused fibers.
Verify the identification label is present, legible, and the WLL matches your load and hitch.
Confirm eye loops are not stretched, deformed or frayed — discard if the shape is distorted.
Check the sling lies flat without kinks, knots or permanent twists from improper storage.
A competent person must carry out a detailed inspection at least every 6 months (or more frequently in harsh environments) per LOLER and ASME B30.9 requirements. Keep a written record: date and examiner, sling serial number and WLL, condition assessment, defects found, and pass/fail status with next examination date.
Store flat or hung on sling racks — never leave coiled on the floor or exposed to moisture.
Keep in a cool, dry, ventilated area away from direct sunlight, heat sources and chemicals.
Clean with mild soap and clean water only — never use chemical solvents or abrasive methods.
Do not drag slings over rough surfaces or sharp edges; use edge protectors when necessary.
Let wet or damp slings dry naturally before storage to prevent mildew and fiber degradation.
There is no fixed service life — discard is based on condition, not age, as determined by a competent person.
Custom WLL, length, width and eye length.
Single to quadplex constructions and special plies.
Custom label printing, customer logos and color coding.
Sampling, OEM/ODM and low MOQ available.
Export packing (carton / wooden case / woven bag) and shipping marks as required.
A webbing sling is a flat woven polyester band, usually with eye ends, providing a wider load-bearing surface for flat or sharp-edged loads. A round sling is an endless loop of polyester yarn core with a woven cover — softer and better for irregular loads. Choose by application and standard.
Yes, the flat profile distributes pressure over a wider area, but always use edge protectors or corner guards when lifting sharp-edged loads, and inspect the sling after every lift.
Every sling is supplied with a serial-numbered test certificate; CE marking and EN 10204 3.1 certificates are available. Third-party inspection (SGS / BV / TÜV) can be arranged on request.
Regular sizes support low MOQ and delivery in about 7–15 days; bulk or customized orders are subject to contract. Contact our sales team for exact terms.
