ABSTRACT:
Individual shelves are provided on the load transport vehicle, which may be a trailor or self-propelled steerable vehicle, so that the shelves may be dropped down adjacent to the roadway for loading and unloading, and lifted up above the clearance height of the vehicle for storage and transport. Guides and bearings are provided between the shelf and body of the vehicle so that the horizontal portion of the shelves will be parallel to the roadway in their lower loading and unloading position to facilitate such loading and unloading, and they will tilt during their travel between such positions so that in the storage position the generally horizontal portion of the shelf will extend downwardly and inwardly to maintain the load on the vehicle with the help of gravity. The frame of the vehicle is provided with a central vertical and longitudinal rib carrying the guides for supporting shelves on each side. The shelves are L-shaped, and are provided with hydraulic cylinders for individually raising and lowering.
