Abstract: A double-deck transportation vehicle has an elevator platform proportioned to extend across the cargo compartment which is mounted on guide rails for vertical movement between a lowered position, an intermediate position and a fully elevated position. When in the lowered position, the platform is located at the floor level. When in the intermediate position, the platform is spaced from the floor and from the roof of the van to provide load storage compartments above and below the platform. When in the fully elevated position, the platform is raised to about the ceiling level. The platform drive mechanism is mounted in a drive compartment which is located within the platform. Elevator cables extend from the drive mechanism to anchor points located adjacent the upper end of the guide rails. The elevator cables extend within the cargo compartment of the van and are not exposed at the exterior of the van. A latching mechanism is provided for releaseably latching the platform in the intermediate position.
