Fall factor and fall distance important for fall protection

WebThe highest fall factor possible is a 2, which puts the maxmimum strain on your rope. A fall factor of 1 is moderate, and a fall factor of less than 1 is light. Dynamic rope considerably decreases the shock a climber feels because it has the ability to stretch and absorb more of the force. Fall Factor: Shock (in kilo-Newtons): Webinstance, not all climbers are 80kg5, and not all gear holds every fall by reason of poor placement, poor rock, or a combination of factors.
