5. Frequently Asked Questions

Q: What does “WLL 400 ton” mean?

A: WLL (Working Load Limit) is the maximum safe load the sling may lift in a straight vertical lift — here 400 tons (400,000 kg). The actual safe working capacity depends on the sling configuration (basket, choker) and lift angle, which must be factored in per EN 1492-2.

Q: What safety factor does this sling have?

A: The sling is manufactured with a 7:1 safety factor in line with EN 1492-2, meaning the minimum breaking load is 2,800 tons for the 400-ton WLL rating.

Q: Can the length and capacity be customized?

A: Yes. Lengths from 2 m to 100 m and custom capacities are available on request. Custom cover colors and logo printing can also be applied for brand consistency on site.

Q: What documentation is provided with each sling?

A: Each sling is supplied with a load test certificate, an EC Declaration of Conformity and a durable capacity tag. Additional third-party inspection (e.g. TÜV, SGS) can be arranged upon request.

Q: How should the sling be stored and inspected?

A: Store in a cool, dry place away from direct UV exposure and chemicals. Inspect the cover for cuts, abrasion or exposed core yarns before every use; remove the sling from service if the core is visible.
