5. Rigging Methods

• Straight Hitch — Full rated WLL of 50,000 kg; ideal for vertical lifting of heavy single loads.

• Choke Hitch — Reduces the rated capacity; recommended for gripping and controlling load position.

• Basket Hitch — Distributes load across two legs; suitable for balanced lifting of long, heavy sections.

• Multiple-Sling Lifting — Combine two or more round slings with a spreader beam for oversized and heavy equipment lifts.

6. Frequently Asked Questions

• Q1: What does a 50 ton round sling mean? — 50T refers to the working load limit (WLL) of 50,000 kg under straight lift. With the 7:1 safety factor, the minimum breaking force is 350,000 kg.

• Q2: What is the difference between a round sling and a flat webbing sling? — A round sling has a high-strength endless fiber core inside a protective sleeve, offering higher capacity per cross-section and softer load contact. Flat slings use layered webbing and are better suited for flat, wide contact surfaces.

• Q3: Can the length be customized? — Yes. Round slings are manufactured to order in any loop length and capacity, with test certificates provided for each batch.

• Q4: Why choose a soft round sling instead of chains or wire rope? — Soft round slings are lightweight, flexible and non-marring; they protect the load surface, absorb shock, and are safer around operators, making them ideal for finished and coated products.

7. Quality & Certification

Every 50 ton polyester soft round sling is produced under strict quality control from core spinning, sleeve weaving, assembly and proof-testing to final inspection. Each sling comes with a factory test certificate and an EC declaration of conformity, ensuring full traceability and compliance for international projects.

8. Safety Notes

• Never exceed the rated working load limit (WLL) of 50,000 kg.

• Inspect the sling before each use; discard if the sleeve is cut, frayed, heat-damaged or the core is exposed.

• Protect the sling from sharp edges, weld spatter and chemical contact.

• Avoid twisting or knotting the sling during lifting operations.

• Store in a cool, dry place away from direct sunlight when not in use.
