1. Product Overview

The WLL 800T polyester round sling is an ultra heavy duty endless round sling engineered for loads up to 800 tons. Built from 100% high-tenacity polyester yarn with a protective woven cover, it combines immense lifting capacity with the soft, flexible, load-friendly handling that round slings are known for — an ideal alternative to wire rope and chain for heavy industrial lifting.

2. Key Features & Benefits

• 800-Ton Working Load Limit — one of the largest polyester round slings available, built to lift transformers, steel structures and heavy machinery safely.

• 7:1 Safety Factor — minimum breaking force of 7 x WLL per EN 1492-2, with 100% load testing and test certificate supplied.

• Soft & Load-Friendly — flexible polyester body conforms to the load, protecting painted, polished or fragile surfaces from scratching.

• Low Elongation — no more than 3% elongation at WLL gives precise, stable lifting control during critical lifts.

• UV & Abrasion Resistant — dense woven cover shields the load-bearing core from sunlight, abrasion and mechanical wear.

• Lightweight & Safe — far lighter and easier to rig than steel chain or wire rope of equal capacity, and it does not generate sparks.

3. Technical Specifications

Note: 800 t is an ultra-heavy custom capacity beyond standard catalog ranges; every sling is made to order with full load testing. Dimensions, effective length and bearing width are manufactured to your drawing.

4. Construction

• Load-Bearing Core — endless loops of high-tenacity polyester yarn laid in parallel, providing the full 800-t lifting capacity.

• Protective Cover — a dense woven tubular sleeve guards the core against UV, abrasion, dirt and moisture.

• Seamless Endless Loop — no splices or joints in the load path, distributing force evenly around the whole sling.

• Permanent Identification — WLL, standard and traceability info clearly marked for safe, auditable use.

5. Typical Applications

• Heavy machinery: press frames, machine tools, turbines and large equipment installation and relocation.

• Steel & energy: transformer lifting, steel structures, pressure vessels, wind power components and offshore equipment.

• Precast & construction: precast concrete segments, bridge girders, caissons and heavy construction modules.

• Shipbuilding & mining: ship blocks, propeller and shaft handling, mining machinery and crusher components.

6. Customization Available

• OEM marking — your brand logo and WLL marking such as WLL800Ton Lift screen-printed onto the cover with factory-grade durability.

• Dimensions — any effective length, sling width and eye configuration per your drawings.

• Colors — cover colors to match your brand or site requirements.

• Packaging — carton, wooden case or export packing per destination.

Q3. What is the working temperature range of the polyester round sling?

Polyester round slings can be used continuously from -40 deg C to +100 deg C. Do not expose the sling above +100 deg C or to contact with sharp edges without edge protection.

Q4. Can we print our own logo and WLL marking on the sling?

Yes. OEM printing is available, including your brand logo and WLL marking such as WLL800Ton, screen-printed or heat-transferred onto the cover with factory-grade durability.

Q5. How should the round sling be inspected before use?

Inspect before every lift for cuts, abrasion, broken stitches, UV or chemical damage and label legibility. Discard immediately if the core or cover is damaged. A competent person must carry out periodic examinations per EN 1492-2.
