High-Strength fiber ropes in off-shore operation on cranes

摘要

The new heavy-lift ship crane HLC 150.000-3000 from Liebherr-lnternational Deutschland GmbH,Biberach a.d. Riss/Germany, has a max. lifting capacity of 3,000 tons and is equipped with several HyperTen fiber ropes from Teufelberger Holding AG, Wels/Austria.Following the innovative fiber rope series soLite, the fiber rope HyperTen from Teufelberger has now arrived in the world of cranes. It has been the established state-of-the-art to move and stabilize loads on deck by means of steel wire ropes. Based on the positive experiences with the fiber ropes, Liebherr has opted for several 34 and 50 mm HyperTen fiber ropes for the heavy-lift ship crane HLC 150.000. The dead weight of the HyperTen fiber rope series is so low that the rope even floats in the water. For attaching loads on deck, the advantages of a lightweight fiber rope compared to a steel wire rope are obvious - the 50 mm HyperTen weighs only 1.4 kg/m against a comparable steel wire rope weighing 11.5 kg/m. The hard-wearing protective cover made of 100% high-strength synthetic fibers ensures the necessary robustness and the ability to identify the point of discard in time. This results in a particularly long service life of HyperTen fiber ropes on deck.
