ABSTRACT:
An abseil rescue system with a velocity control system, allowing a user to descend on a rope, comprising two holders, two brakes, two retarders, and a frame. The retarder and the brake grip the rope of the abseil rescue system simultaneously, allowing to control the velocity of descent accurately. The weight of the user helps to grip the rope, such that for a tight grip the user is not required to apply much force.
