2. Product Overview

The WLL 1000T polyester round sling is an ultra-heavy-duty endless lifting sling engineered for the most demanding lifting operations. Its load-bearing core is formed by continuous loops of high-tenacity polyester (PES) filament yarn, enclosed in a tough, wear-resistant protective sleeve. This design delivers an outstanding strength-to-weight ratio: enormous lifting capacity in a soft, flexible, lightweight sling that conforms naturally to the shape of the load.

Unlike steel chain or wire rope slings, polyester round slings protect the load surface from scratches and damage while remaining easy to handle and store. Rated to a working load limit of 1000 tonnes, this sling is built for heavy industrial, offshore, shipbuilding, and civil-engineering applications where safety and reliability are non-negotiable.

3. Key Features & Benefits

• Ultra-high capacity — WLL 1000 t (approx. 9,800 kN) for the heaviest lifting jobs

• Endless round-sling construction — continuous load-bearing fibre loops, no load-bearing stitching in the core

• Soft and flexible — conforms to the load shape and protects fragile or finished surfaces from damage

• Lightweight and easy to handle — far lighter than steel slings of equivalent capacity

• Wear-resistant protective sleeve — shields the core from abrasion, cuts and UV exposure

• High visibility and easy inspection — the sleeve colour and core condition can be checked at a glance

• Custom-made — length, diameter, sleeve colour, fittings and packaging configured to your order

• Resistant to corrosion, chemicals and moisture — no metal core to rust
