Abstract: A cargo delivery vehicle has storage for multiple tiers, or levels, of cargo. The delivery vehicle includes a plurality of interior pallet elevators, at least one on either side of a center structural wall running parallel to the side walls. Specialized pallets are provided for use with the pallet elevators. The pallet elevators are powered by redundant hydraulic cylinders which drive four cross-shaft-linked chains to lift and lower the pallet support shelves. Compact rear access doors slide vertically to allow easy access for loading or unloading. Substantially continuous side access doors provide total exterior access to the lowermost tier of cargo by delivery vehicle personnel standing on the ground. Cargo stored at the upper tier may be positioned by an elevating means at the level of the lower tier for either rear loading or side retrieval purposes.
