  • Patent number: 4574613
    Abstract: A powerful and versatile lightweight power post system for the repair of "unibody", or unitary body and frame type automobiles. The basic post is of relatively lightweight tubular construction and has a small base for holding it erect. An elongated power assembly which is tubular and fits over the post is movably mounted at the upper end of the post by a winch which is mounted on the power assembly. Toward the bottom of the power assembly is the main power pulley, and at the upper end of the power assembly is a pivotally mounted power arm. A powerful hydraulic ram extends from the lower end of the elongated power assembly near the main pulley outwardly from the post to a point on the pulling arm spaced well away from the main post. An additional pulley may be mounted on the upper pulling arm between the mounting point for the hydraulic ram and the post. A lower pulley is mounted on the post on a slider assembly to provide a versatile second pull.
