ABSTRACT:
An assembly of components and a method of using such components for straighening and repairing vehicle bodies, frames or for bending various metal components in an efficient manner. The present invention includes the use of hydraulically actuated rams to provide a force to straighten or bend metal components and a chain or similar structure to transfer the force produced by the hydraulic ram to the metal component to be straightened or bent. Unique base plates are provided for supporting one end of the hydraulic ram from a vehicle runway, platform or other stationary surface. A unique socket and stop assembly is provided for supporting the hydraulic ram from a transverse beam and also to form a stop for precluding movement of the transverse beam. A unique chain anchor is mounted on the transverse beam and anchors one end of a chain thereto thereby eliminating the necessity of providing hooks on one end of a chain and also enabling optimum vector angle of the tension force in relation to the metal component being straightened or bent. Unique stands are provided for support of crossbars extending under the vehicle which support clamps which lock the vehicle from moving while corrections are being made on the body with the stands having unique clamps for supporting them in position on the runways. A unique structure to enable pull down forces to be exerted on a vehicle component or other metal component is provided to enable vertical forces to be exerted when necessary. The unique components may be assembled quickly and efficiently in necessary positions to effectively straighten and repair vehicle bodies, frames or other metal components.
