ABSTRACT:
A portable anchoring system forms a height-adjustable rectangular frame extending outwardly all around an automobile body to which holding devices adjustably mounted on it clamp, providing a self-anchoring base to which conventional "pull dozers" can be chained and apply pulling and pushing forces without need for floor anchorage; to assemble the frame, a pair of side assemblies movably supported in use-attitude on transfer-ball-equipped jack-bases provide adjustable clamps which extend inwardly for affixation to a vehicle body to be repaired, and after clamping are joined by two end rails; an adjustable cross-bar is provided for applying pushing and pulling forces beneath a vehicle body.
