Parallel spaced posts are rigidly connected by a cross member to form an H-shaped frame, and the frame is supported by carriage members within tracts for linear and tilting movement between a storage position under the floor of a vehicle body and a vertical operating position adjacent a doorway within a side wall of the body. The posts support movable intermediate tracks which support movable elevator members carrying a platform pivotable between an extended horizontal position and a retracted storage position adjacent the posts. Hydraulic cylinders move the frame between its storage and operating positions and also move the elevator members and platform vertically between a bottom position on the ground and an upper position flush with the floor of the body.
