Rescuing device for rescuing persons from the chairs of inoperative chairlifts or the like in which on a supporting member rollers are provided, against which the cable carrying the chairs is pressed by a braking plate, said braking plate being movable on the supporting member in a direction normal to the extension of the cable. On the braking plate spring means are acting, which can be compressed by an adjustable lever. On the supporting member there is provided a cylinder, supported by a free-wheeling bearing rotatable in one direction of rotation and not rotatable in the other. A rope is wound around the outer periphery of the cylinder and to a first end of the rope a belt is connected such that a person to be rescued and sitting in the belt by its weight generates a frictional braking force between the rope and the outer periphery of the cylinder. A person participating in the rescuing operation can slide down an inclined cable to which the chairs are connected, while sitting on a transporting means connected to the supporting member and control its speed by operating the adjustable lever.
