Abstract
A winch has a drum that winds and unwinds a cable in response to winding and unwinding of tethers about an axle The tethers are connected to telescopic spring devices with staged concentric springs that store energy, and a brake is releasable to permit the drum to rotate under the force of the stored energy. The drum has a diameter that is greater than a diameter of the axle thereby producing a mechanical advantage. The cable is also connected to a passenger carriage of an amusement ride that travels under the force of the stored energy.
