Abstract

High strength polymer fibres are opening new fields in regard on their strength to weight ratio. In 2009 Liebherr and Teufelberger started a development partnership to utilise these opportunities and rethink the basics of hoist ropes for cranes: (1) Introduction; (2) The high strength fibre rope soLITE; (3) Load bearing capacity of the rope; (4) Liebherr fibre crane series; (5) Discard criteria.

Highlights

  • Liebherr is covering a wide spread field of on- and offshore crane applications

  • With the new fibre rope, Liebherr and Teufelberger have opened a new chapter in the history of running ropes

  • For the first time the potential of high performance polymer fibres is used in hoist ropes

Summary

Introduction

Liebherr is covering a wide spread field of on- and offshore crane applications. The rope weight reduces the load capacity of the whole crane system. When regarding the increase in specific strength of modern polymer materials back in 2009, Liebherr and Teufelberger started a development partnership to bring new materials into hoist ropes. Liebherr presented their result, the new Fibre-Crane Series, on Bauma 2019 and started with the delivery in January 2020
