  • Patent number: 7303205
    Abstract: A device for selectively compressing and decompressing an anti-sway bar. The device replaces the hand crank on traditional anti-sway bars and relieves drivers of having to get our to their vehicles to compress or decompress the anti-sway bar by hand. A lever is used to compress the anti-sway bar. The lever's head is attached to the anti-sway bar at the same position as the old hand crank, using the bolts and nuts from the hand crank. The lever is raised with the assistance of an electric motor that is controlled by a switch in the cab of the towing vehicle. The motor turns a screw that extends through a nut in the handle of the lever. Micro-switches are used to automatically stop the electric motor when the lever has reached a desired position.
