ABSTRACT:
The movement of the lift gate between ground and cargo bed positions is controlled by an attitude control mechanism which effects a change in attitude from horizontal at the bed position to slightly downwardly and rearwardly inclined at the ground position. The platform is raised by lift arms which are coupled to the platform by longitudinally movable pivots which enable the attitude change. The attitude control mechanism includes generally parallel arms pivotally connected to platform uprights; and the platform is pivotally connected about a horizontal axis to the platform uprights. Support arms between the platform and the platform uprights maintain the generally horizontal attitude of the platform. Latch means associated with the platform uprights, latch the uprights and the platform to the cargo bed in the bed position. The platform is swingable upwardly and downwardly relative to its pivot axis for ramping with a loading dock. The platform is swingable upwardly by the lift arms, in the bed position, to swing the platform to a vertical storage position.
