CLUTCH™ Drop Test 11 mm (7/16 in)

CLUTCH™ DROP TEST 11 MM (7/16 IN)

TEST METHOD

The CLUTCH is designed to arrest a fall and limit the dynamic impact load by safely slipping a limited amount of rope during an impact to dissipate energy. To inform users about the dynamic performance across a wide range of industry ropes, drop tests were performed with several ropes.

Note: For each drop, the maximum arrest force is captured by a high-speed load-cell. The distance of rope slipping through the device is recorded as well as the total system extension.

KEY TAKEAWAYS

11 mm CLUTCH tested on thirteen 10.5-11 mm ropes showed a max arrest force of 6.6 kN to 10.1 kN.
11 mm CLUTCH safely arrested the fall with no visible damage to the ropes in all 13 cases.
11 mm CLUTCH rope slip ranged from 35 mm to 680 mm across industry ropes.
11 mm CLUTCH system extension ranged from 180 mm to 990 mm across industry ropes.

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 were 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.
