Understanding the mechanics of dynamic rope brakes
2010
Procedia Engineering
Dynamic rope brakes are integral elements of the standard belaying equipment. They multiply the hand force of the belayer and convert a fraction of the falling climber's kinetic energy into thermal energy. As the rope is deflected by the brake, the thermal energy is produced by belt friction. This paper introduces a brake model based on static and viscous belt friction. The contact angles of three different brakes (figure-of-eight, ATC and HMS [Munter hitch]) were determined. These data as well
