When It Gets Really Heavy – the DoUltra Round Sling (WLL 35,000 kg)
Some loads don’t forgive weakness. That’s exactly why the DoUltra round sling was developed – engineered to lift the heaviest components with maximum safety and minimal weight. This heavy-duty sling is the perfect solution when you’re working with large machines, components, or steel structures – especially in tight spaces or with small crane hooks.

Lift Lighter. Use Longer – The Advantages in Detail
With a core made from ultra-high-molecular-weight polyethylene (UHMW-PE), the DoUltra is significantly lighter than conventional polyester round slings, while maintaining the same high lifting capacity. Its circular braided sleeve hugs the core tightly, allowing it to fit into smaller lifting points without being crushed. The greatly reduced elongation ensures precise and controlled lifting – ideal for sensitive or asymmetrical loads. And if the sleeve becomes damaged? No problem – the lift can still be completed, as the sleeve only bears load at the suspension point.
