Abstract
Apparatus for straightening structural parts, such as vehicle parts which can be removed from a vehicle and straightened after being bent out of shape due to a collision with another object. The apparatus includes a table on which the structural part can be mounted. The table has first and second center bars in adjacent horizontal planes, the center bars being movable relative to the table into any one of a number of operative positions. At least one outer end of each center bar is provided with means for adjustably mounting a fluid actuated power device, each power device being coupled to an upright post, whereby a chain, cable or rod can be coupled between the post and a structural part for applying a pulling force to the structural part for returning the structural part to its normal operative shape. The apparatus is substantially self-contained in that the power sources for operating the power devices can be foot or hand actuated compressors for applying pressurized fluid to the power devices. The apparatus is especially suitable for straightening frame extensions, impact bars and side brackets of Chevrolet Corvette automobiles.
