ABSTRACT:
An apparatus for applying straightening forces to vehicle members. A relatively light adjustable rectangular cradle is equipped with clamps for clamping the cradle to the frame or pinch weld of a vehicle to be repaired. A transversely adjustable journal mounted on one of the beams of the cradle acts as a pivot point for a relatively long power beam which rests on the floor under the cradle and the vehicle. A hydraulically driven pivoted arm at the distal end of the power beam provides the straightening forces.
