Lifting Slings & Webbing

Overview

The Lifting Slings & Webbing category comprises high-tenacity polyester lifting slings, round slings, and end-fitting assemblies engineered for overhead lifting, load positioning, and rigging in industrial environments. Each product is constructed from 100% high-modulus polyester yarn, chosen for its low elongation (typically 3–7% at working load), abrasion resistance, and resistance to acids and most chemicals, with hardware components manufactured from forged or stamped alloy steel. Manufactured to internationally recognized frameworks including EN 1492-1 (flat woven webbing slings), EN 1492-2 (round slings), ASME B30.9, and WSTDA recommended practices, this range delivers a consistent 7:1 safety factor for lifting duty across all standard capacity classes.

Key Specifications & Standards

Lifting slings differ from lashing/tie-down products in their higher safety margins and duty ratings. The specifications below reflect the standard production envelope; custom values are available on request.

• Working Load Limit (WLL): capacity classes from 0.5 ton (1,100 lbs) through 10 ton (22,000 lbs) vertical, with the flagship 2 Ton Lifting Sling rated at a WLL of 2,000 kg (4,400 lbs) in straight vertical pull.
• Breaking Strength / MBL: minimum breaking load calculated at 7× WLL — e.g., the 2-ton class provides a minimum break force of approximately 14,000 kg (137 kN / ~30,800 lbs).
• Safety Factor: 7:1 for all lifting-rated webbing and round slings per EN 1492 and ASME B30.9 (note: tie-down/lashing product safety factors of 3:1 to 4:1 under EN 12195-2 and DOT / FMCSA 49 CFR 393 apply only to cargo restraint, not overhead lifting).
• Webbing Width: standard widths of 25 mm (1"), 50 mm (2"), 75 mm (3"), and 100 mm (4"), with wider single- and double-ply constructions available for higher capacity classes.
• Standards Compliance: EN 1492-1, EN 1492-2, ASME B30.9, WSTDA-WS-1, ASTM material test methods, with color-coded WLL identification per the EN duty-rating chart.
• Temperature Range: continuous service from −40 °C to +100 °C (−40 °F to +212 °F) for polyester; performance derating applies above +80 °C.
• Elongation: ≤ 7% at rated WLL, ensuring controlled, predictable load behavior during lifts.
• Fitting Hardware: forged alloy steel eyelets and end fittings rated to match or exceed the sling WLL, with proof-load testing to 2× WLL.

Capacity & Width Reference

**2 t (4,400 lbs)**	**14,000 kg / ~137 kN**	50 mm	Heavy-duty lifting
**3 t (6,600 lbs)**	**21,000 kg / ~206 kN**	75 mm	Structural loads
**5 t (11,000 lbs)**	**35,000 kg / ~343 kN**	90 mm	Construction lifts
**10 t (22,000 lbs)**	**70,000 kg / ~686 kN**	100–150 mm	Machinery placement

Product Range

Double Eye Polyester Webbing is a flat woven sling terminating in a reinforced, folded eye (also called a soft loop) at each end, engineered for choker, basket, and vertical hitches. The double-eye configuration protects the wear-prone termination points and extends service life in repetitive lifting cycles, with each eye reinforced to preserve rated capacity where the sling meets the hook or shackle.

Steel Eyelet End Fittings are forged or stamped alloy steel terminations swaged, sewn, or bolted to webbing ends to provide a rigid, high-abrasion connection point. These fittings are proof-loaded to 2× WLL and matched to the sling's capacity class, delivering secure attachment to cranes, hoists, and spreader bars while reducing eye wear in high-cycle industrial duty.

Woven Polyester Lifting Sling is the core flat-web product of the range, available in single- and double-ply constructions with color-coded WLL identification per EN 1492-1. Its wide, flat bearing surface distributes load across the lifted object, minimizing point stress on finished or delicate surfaces — a key advantage in Construction & Infrastructure and precision equipment handling.

2 Ton Lifting Sling - Heavy Duty Polyester Round Sling is an endless round sling with a continuous load-bearing polyester core encased in a durable double-jacket cover, rated to a WLL of 2,000 kg (4,400 lbs) vertical. The tubular jacket protects the core yarns from abrasion and UV exposure, and the endless design allows the wear surface to be rotated for extended service life in demanding Lifting & Rigging operations.

Applications

These slings are specified across sectors where load integrity, repeatable performance, and traceable certification are mandatory.

• Lifting & Rigging: overhead crane lifts, hoisting, choker and basket hitches, and multi-leg bridle assemblies for balanced load handling in workshops, ports, and fabrication yards.
• Construction & Infrastructure: placing precast concrete panels, steel beams, HVAC units, and prefabricated modules on active job sites, where the wide bearing surface protects finished surfaces from damage.
• Logistics & Transportation: loading and unloading containerized freight, palletized machinery, and oversized cargo at distribution hubs, ports, and intermodal terminals.
• Machinery & Equipment Installation: positioning motors, pumps, generators, and industrial plant with controlled, low-stretch lifts that maintain load stability during placement.
• Wind, Energy & Utilities: handling turbine components, transformers, and pipeline sections where high WLL classes and abrasion-resistant round slings are required.
• Manufacturing & Shipyards: repetitive production-line lifting and heavy sub-assembly movement where color-coded WLL identification supports fast, error-free sling selection.

Customization & Wholesale

TrustWebbing supplies the Lifting Slings & Webbing category to global wholesale, distributor, and OEM buyers with full customization across capacity, dimension, fitting, and branding requirements.

Minimum Order Quantity (MOQ): standard MOQ is 500 pieces per specification for stock configurations, with 1,000+ pieces recommended for fully custom webbing colors or bespoke fitting assemblies. Trial and sample orders can be arranged for qualification and load testing prior to bulk commitment.
