When It Gets Really Heavy – the DoUltra Round Sling (WLL 10,000 kg)
Some loads leave no room for weakness. That’s exactly what the DoUltra round sling was made for – designed to lift the heaviest components with maximum safety and minimal weight. This heavy-duty round sling is the perfect choice when working with massive machines, structural parts, or steel components – especially in tight spaces or with small crane hooks.

Lift Lighter. Use Longer. – The Advantages in Detail
Built around a core made from ultra-high-molecular-weight polyethylene (UHMW-PE), the DoUltra is significantly lighter than standard polyester round slings – while maintaining the same lifting capacity. Its circular braided sleeve wraps tightly around the core, allowing it to fit into smaller attachment points without being compressed. Its extremely low elongation ensures precise lifting – ideal for delicate or asymmetrical loads. And if the sleeve gets damaged? No worries: you can complete the lift, as the sleeve is only under load at the suspension point.

And for greater clarity and tidiness in your storage area: the Dolezych sling storage stand ensures your slings and lifting gear remain clean, sorted, and always within easy reach.
