Abstract: An apparatus for straightening damaged automobile frames or bodies utilizing a rigid structural ramp capable of supporting a vehicle. A preferably hydraulic power source capable of imparting alternatively a compressive or a tensile force to the damaged frame or body is adjustably mounted on a wheeled post which slideably travels a continuous track circumventing the ramp. The ramp is provided with improved chain anchoring openings. A chain can be used for a applying tensile force to the frame directly or indirectly to the frame by connecting a chain first to the anchoring opening, then to the damaged frame, and then to the hydraulic power source.Using two wheeled posts on the continuous track, a rotatable, pivotal, cross bar can be attached at its respective end portions to the wheeled posts. With the power source mounted on the cross bar, repairs can be made to the roof, or interior portions of an automobile.
