Reduced Rope Operating Temperatures

GORE Performance Fiber for High Performance Ropes dramatically reduces the rope surface temperature during operation.

Tension Member Technology monitored the rope surface temperature during the bend over sheave testing.  The 12-strand 3/4 inch Vectran® LCP yarn braided ropes made by Cortland Cable were constructed with and without GORE Performance Fiber for High Performance Ropes.
Test conditions: Load, 18.5% of break strength; cycle rate, 500 cycles/hour; speed, 1.1 ft/sec; D:d, 20; sheave, 15 inch.
