Radier 11 mm

Type B semi-static ropes specially developed for rapid descent from helicopters by special forces.

Their Aramid sheath does not melt, even against a descender overheated by the descent.

Whereas classic ropes in polyamide or polyester have a very limited lifetime because their sheath melts, rendering the rope stiff and useless, Raider ropes permit multiple descents.

ROPES RESISTANT TO HIGH TEMPERATURES

EFFECT OF HIGH TEMPERATURES ON ARAMID
The resistance of Aramid to high temperatures is best illustrated by the graph illustrating the residual strength after exposure to raised temperatures.
Thus we may for example see that after 10 hours of exposure at 200C it retains 100% of its strength, or that after 1 hour at 350C it retains 90% of its strength.

TEST WITH BLOWTORCH
Semi-static rope holding a mass of 100kg exposed to a temperature of 400° C (+ or- 50° C) for 15 minutes:
Results:
• Classic 11 mm rope: Break after around 40 seconds
• Raider 11 mm rope: Residual strength around 1500 daN after 15 minutes.
• Raider Tactic 11 mm rope: residual strength around 1000 daN after 15 minutes.

The rope supports a 100 kg mass.
It is held clear of a 25 mm bar heated red-hot.
It is released against the bar and the time to rupture measured.
Results:
• Classic 11 mm rope : 3 seconds
• Hotline 11 mm : 5 seconds
• Raider Tactic 11 mm : 8 seconds
• Raider 11 mm : 18 seconds
