DoUltra Heavy-Duty Round Sling, WLL 50,000 kg, UHMW-PE

Maximum Performance at Minimal Weight – The DoUltra Round Sling (WLL 50,000 kg)

Do you work with extremes? Then you need a heavy-duty round sling that delivers exactly that: uncompromising strength, maximum safety, and handling that makes your daily operations noticeably easier. The DoUltra round sling, with a core of UHMW-PE (Ultra High Molecular Weight Polyethylene), is the solution to all large-scale lifting challenges – lightweight, compact, and efficient.

Extremely strong. Surprisingly compact. Remarkably precise.

Compared to conventional polyester (PES) round slings, the DoUltra offers multiple advantages: thanks to the UHMW-PE fiber, it is up to 60 % lighter while maintaining the same load capacity – ideal for extended operations, frequent rigging changes, and critical lifts. Its compact design ensures it fits even smaller crane hooks without being crushed. With minimal elongation, it behaves almost like a wire rope when lifting, allowing for extremely precise movements. The external marking is provided via a hook-and-loop sleeve with RFID, keeping the protected label easily accessible at all times.
