When It Gets Really Heavy – the DoUltra Round Sling (WLL 15,000 kg)

Some loads don’t forgive weakness. That’s exactly why the DoUltra round sling exists – designed for lifting the heaviest components with maximum safety and minimum weight. This heavy-duty sling is the ideal choice when working with massive machinery, structural parts, or steel elements – even in tight spaces or with small crane hooks.

Lift Lighter. Use Longer – Advantages in Detail
With 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 fits snugly around the core, allowing use in smaller lifting points without deformation. The extremely low elongation ensures precise and controlled lifting, perfect for sensitive or asymmetrical loads. Even if the sleeve becomes damaged, the lifting process can be safely completed – the sleeve only bears load at the suspension point.

Fully Protected – Accessories for Maximum Safety

And for optimal organisation on site, the Dolezych lifting gear stand keeps slings and accessories clean, sorted, and always within reach.
