WLL Range
1,500 lbs - 20,000 lbs
At a Glance
The TrustWebbing Woven Polyester Lifting Sling is a flat, single-ply and multi-ply soft sling manufactured from 100% high-tenacity woven polyester yarn. Designed for overhead lifting, rigging, and material handling across construction, manufacturing, shipping, and warehousing environments, this sling offers a soft, flexible surface that protects finished loads while delivering dependable strength. Polyester construction provides excellent resistance to UV exposure, moisture, and most acids, along with low elongation (approximately 3% at rated load) for controlled, predictable lifts.
Each sling is color-coded in accordance with the international WLL system, allowing riggers to identify capacity at a glance. Reinforced lifting eyes, abrasion-protected wear points, and a durable label sleeve ensure long service life in demanding industrial applications. Slings are produced to a 7:1 safety factor and are available in eye-and-eye (flat) and endless (grommet) configurations.

Built to Last
- Woven from 100% high-tenacity polyester filament yarn for high strength-to-weight ratio and low water absorption.
- Single-ply and double-ply constructions available; double-ply adds 2x the abrasion resistance for rough or edged loads.
- Rated with a 7:1 safety factor, meaning breaking strength is seven times the marked WLL.
- Low elongation of approximately 3% at rated load for stable, controlled lifts.
- Reinforced eyes with a taper design distribute stress and increase eye efficiency to roughly 80% of body strength.
- Optional sewn-on wear pads and edge guards at high-abrasion contact points extend service life by up to 50% in heavy cycling.
- Heavy-duty PVC or leather sleeve reinforcement available on lifting eyes for added protection against cutting.
- Durable, weather-resistant identification label listing WLL, material, length, and serial number, protected in a clear sewn sleeve.
- Stitching thread is high-tenacity polyester in a contrasting color to make wear and damage inspection fast and reliable.
Where It's Used
- Overhead lifting and rigging of machinery, steel structures, and fabricated assemblies.
- Handling of coated, painted, or polished loads where soft slings prevent surface damage.
- Construction site material handling, including precast concrete, pipe, and beams.
- Shipping, port, and container loading/unloading operations.
- Warehouse and manufacturing line lifting of pallets, crates, and heavy components.
- Wind energy, oil & gas, and marine sectors requiring UV- and moisture-resistant slings.
- General maintenance, HVAC unit placement, and equipment installation.
