A vehicle repair support rack is provided for support in elevated position relative to a repair shop floor and includes support structure therefore whereby one end of the ramp may be raised and lowered relative to the floor. Opposite longitudinal side portions of the rack and the aforementioned one end thereof include peripheral track structure extending thereabout and at least one carriage is mounted for the track structure for movement therealong and projects considerably horizontally outwardly of the periphery of the rack. A portable, wheeled pull tower for use in conjunction with a repair shop floor anchored track is provided and is loadable onto the rack by the carriage (which includes an upper platform surface) when the one end of the rack is lowered and the carriage is supported therefrom to enable the platform thereof to define a loading ramp for the pull tower. The carriage includes the equivalent of floor a anchored track with which the base the pull tower may be removably anchored, the carriage is releasably lockable in selected positions along the track and the upper tower portion of the pull tower supporting the pull developing force structure is mounted from the lower portion of the pull tower for angular displacement relative thereto about an vertical axis and includes outwardly and downwardly inclined brace structure equipped with a footed lower end for abutting engagement with the platform of the carriage to resist deflection of the pull tower in a direction opposite to the pull force exerted thereabout.
