Because of the rough operating conditions prevailing in rotary drilling rigs, a great deal is demanded of their crowd ropes. The challenges that EVOLUTION Q8 from TEUFELBERGER perfectly copes with in crowd rope applications are enormous shock loads and permanent vibrations, as well as a constant exposure to dirt and sometimes extremely small deflection sheaves.

Benefits of EVOLUTION Q8:

  • Very long service life due to the rope’s high flexibility even at low d/D ratios (sheave diameter to rope diameter)
  • Robust against shock loads due to the PLASTFILL® insert between the rope’s core and its outer strands
  • High operational safety due to the excellent flexural fatigue characteristics ensured by the rope design
  • Due to the gentle compaction process particularly suited for applications with high numbers of bending cycles
