TECHNICAL INFORMATION Energy Absorption in Arborist Rigging EQUAL LOAD Falling 40 Feet BOWLINE RIGGING BLOCK RIGGING LINE FALLING FORCE 1/2" Stable Braid 100% POLYESTER Provides the greatest control FALL DISTANCE Distances and measurements are for illustration purposes only. LOAD VS. ELONGATION OF RIGGING LINES 9,000 8,000 The load vs. elongation curves of two ropes with similar breaking strengths. The shaded area beneath each of the curves represents the energy absorbed as the Rope Tension (lb-f) 7,000 6,000 5,000 4,000 3,000 1/2" Stable Braid 1/2" Nystron 0% 5% 10% 15% 20% rope stretches. The two areas shown are 2,000 equal representations of the same energy 1,000 absorption or the catching of the same falling load. As shown, Nystron absorbs the 0 energy while reaching the lowest load, but stretching the farthest. Elongation %
