When It Gets Really Heavy – the DoUltra Round Sling (WLL 30,000 kg)
Some loads allow no margin for weakness. That’s exactly what the DoUltra round sling was built for – developed to lift the heaviest components with maximum safety and minimum weight. This heavy-duty sling is the perfect solution when you're working with massive machinery, large components, or steel structures – especially in tight spaces or with small crane hooks.

Lift Lighter. Use Longer – The Benefits in Detail
With a core made of ultra-high-molecular-weight polyethylene (UHMW-PE), the DoUltra is significantly lighter than traditional polyester round slings while offering the same impressive lifting capacity. Its circular braided sleeve fits snugly around the core, allowing it to slide easily into smaller lifting points without being compressed. The greatly reduced elongation ensures precise and controlled lifting, especially important for sensitive or asymmetrical loads. And if the outer sleeve is damaged? No problem – the lift can still be completed, as the sleeve is only under load at the suspension point.

And for a more organised and efficient storage area: the Dolezych sling storage stand keeps your round slings and lifting gear clean, sorted, and always within reach.
