ABSTRACT:
A load platform is hingedly connected at its forward edge to the lower ends of a laterally spaced pair of vertically elongate runner assemblies that are vertically movably mounted on a supporting framework. Upper ends of the runner assemblies are fitted with pivotally mounted retainer brackets foldable between horizontally rearwardly extending load restraining position and vertically folded position. Selectively actuable means are provided for effecting pivotal movement of the load platform between horizontally rearwardly extending load bearing position and vertically extending folded position to concurrently effect folding and unfolding movement of the pair of bracket retainers by direct or indirect contact with the rear edge of the platform.
