ABSTRACT:
An abseil rescue system, comprising: a velocity control system with two brakes and two retarders; a rope winder with a rope; and a frame, having a base and a gallows with two height positions. The two brakes and the two retarders act on the rope, allowing for controlled and safe descent of a person. The base has a reel with a crank, where a transmission cord is wound up, which leads to the upper front end of the gallows, with a hook fastened to the free end of the transmission cord. By turning the crank, the gallows is brought in a high position to provide a high suspension point for the rope winder.
