Description

Applications :

  • Construction of 3:1 or 4:1 hoists.
  • Applications requiring low rope movement and low angle.
  • Rope work where fatigue reduction is important.

Important points:

  • Maximum load depends on rope deflection angle.
  • A 60° angle allows 100% load utilization.
  • An angle of 180° allows 200% load utilization.
  • Textile bonding ensures better load distribution.
