Appl. No.:

09/605502

Robert J. Greenlaw - Houston TX 77041

International Classification:

B60P 102

US Classification:

187244, 187249, 187255, 414679

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. The longitudinal center structural wall supports a plurality of transverse diagonal braces that extend from approximately the mid-point of the center structural wall to the upper outboard corners of the outer sidewall frames.

Abstract:

A cargo delivery vehicle is described having storage for multiple tiers, or levels, of cargo. The delivery vehicle includes one or more elevator assemblies, each of which includes two cargo storage platforms movable so that cargo can be loaded on both platforms from a height corresponding to the upper storage tier and unloaded from both platforms from a height corresponding to the lower storage tier. The elevator assemblies are provided with stabilizing guide rails along which the cargo platforms are raised and lowered. The guide rails of each elevator assembly are spaced so as to allow loading and unloading of cargo from the front, rear, or either side of the vehicle. To minimize loading of the floor and side walls of the delivery vehicle, the elevator assemblies and their cargo are suspended from a deep center truss extending along the length of the delivery vehicle, permitting the weight of the cargo to be borne directly by the vehicle's axles so that non-structural panels, including cargo access doors and insulating panels, can be used in the side walls and floor of the delivery vehicle.

Abstract:

Substantially continuous side access doors provide total exterior access to the lowermost tier of cargo. 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. The center structural wall supports a transverse roof truss system that carries suspended outboard loads inward to the center wall. This non-traditional framing system greatly reduces the structural requirements of the side walls and floor, thereby permitting largely open framing for multiple side access ports as well as a minimized floor thickness to permit easier access from the pavement.
