ABSTRACT:
A generally horizontal vehicle supporting rack is provided for support from a floor surface and includes depending support means intermediate its opposite ends for support from the support surface and mounting the rack for oscillatory movement between a horizontal position and an inclined position with one end of the rack swung downwardly toward the floor surface. The rack is yieldingly biased toward the horizontal position and includes fixed leg structure positively limiting movement of the rack from the inclined position to the horizontal position. Further, an elongated pull tower base having a pull tower pivotally mounted from one end thereof for angular displacement about a vertical axis is provided and includes opposite end portion floor engageable support wheels. The other end portion of the base is lengthwise displaceable laterally beneath one marginal portion of the platform and the base is rockable over the support wheels adjacent the one end thereof to elevate the other end portion for releasable locking in position relative to and beneath the rack marginal portion. Further, a vehicle chassis support stand is mounted from the inner end of an elongated base disposed transverse to and releasably secured to the rack marginal portion and the elongated base is pivotable about the outer end for swinging movement of the base inner end and the support stand toward the outer edge of the rack marginal portion.
