ABSTRACT:
A straightening apparatus for use in straightening the bent portions of vehicles including a support frame in which the vehicle is positionable; a pusher unit adjustably mounted on the support frame and adapted to engage the bent portion of the vehicle and applying a straightening force thereto in a first direction; and a backup unit adjustably mounted on the support frame and adapted to engage the vehicle in the vicinity of and in opposition to the pusher unit and apply backup forces to the vehicle oriented generally parallel to the straightening force and in a second direction opposite to the first direction so that the bent portion of the vehicle can be straightened back to its original shape without deformation of the unbent portions of the vehicle.
