CLUTCH™ SLIP TEST

TEST METHOD

The CLUTCH™ is designed to provide safe rope slip in overload situations. To assess the point of slip across a wide variety of industry ropes, the device was anchored, and various ropes were pulled through the device at a rate of ~15cm/min. 

KEY TAKEAWAYS

  • Across the thirteen 10.5-11mm industry ropes tested, the CLUTCH achieved safe and reliable slip between 7.3kN and 11.56kN.
  • In all cases, no visible damage to the rope or device was observed as a result of the slip event.

WARNINGS

  • THIS DATA IS PROVIDED FOR INFORMATIONAL PURPOSES ONLY
  • For each rope type, a minimum of two samples from a single lot of new rope was tested in a controlled laboratory environment.
  • CLUTCH slip behavior is influenced by many factors including lot-to-lot rope variability, variation in rope diameter, rope and device wear, environmental conditions, etc.
  • Fully read and comprehend the CLUTCH Manual prior to use in any rigging scenario.
  • Obtain professional training to industry standards prior to CLUTCH testing/application.
  • Consult a qualified technician or trainer before attempting techniques on your own.
