Abstract:
A vehicle frame straightening system, comprising:(a) a rigid post vertically secured to a rigid base; (b) a circumferential post sleeve slidably mounted about an upper segment of said post; (c) an elongate pulling member including frame engagement means at one end thereof; (d) a circumferential sleeve slidably mounted about a central segment of said pulling member, said sleeve having a frame opposing end and a frame-distal end; (e) an axle having one segment thereof rigidly mounted transversely upon said circumferential post sleeve; (f) means for pivotally securing said pulling member sleeve, at a medial location thereof, to another segment of said axle; (g) first linear position power actuation means (LPPAM) pivotally mounted to said post sleeve above said axle, said first LPPAM having a drive end and a driven end, said driven end pivotally spool-coupled to said frame-opposing end of said pulling member sleeve; (h) first and second scissors arms pivotally coupled to each other at opposing ends thereof, said first arm also pivotally secured to a distal end of said pulling member and said second arm pivotally secured to a frame-distal end of said pulling member sleeve; and (i) second LPPAM having a drive end and a driven end, said drive end secured transversely between said scissor arms, said drive end spool-coupled to said first arm and said driven end coupled in a linear incremental advance relationship to said second arm, whereby selectable actuation of said first LPPAM will rotatably calibrate the angle of action of effect of said elongate pulling member on the vehicle frame and selectable actuation of said second LPPAM will control incremental linear pulling of said elongate member and said frame engagement means thereof.
