A component part container delivery rack used in manufacturing operations. An E-frame defining at least two compartments that are open on at least one side that extends between the front and back ends of the rack. The frame is supported on a plurality of wheels and is adapted to receive a dolly in the compartment. Each dolly is removably received in one of the compartments and locked in place when placed in the delivery rack. The locking element includes a pivoting lever that is rotated to lock and unlock the dolly within the compartment. The dolly is supported on roller guide elements that guide the dollies as they are moved into and out of the compartment. The dollies are raised above the floor so that the wheels of the dollies do not contact the floor as it is transported by the rack.

1. A component part container delivery rack system for use in manufacturing operations, comprising:a component part container; a dolly associated with and supporting the component part container, the dolly having a plurality of wheels for moveably supporting the dolly; a frame having a front end, a back end, and a center rail disposed between the front and back ends, the frame having at least two compartments that are open on at least one side that extend between the front and back ends, the frame being supported on a plurality of pivotal wheels; a plurality of rollers rotatably disposed on the front end, the back end, and the center rail, the plurality of rollers having at least one roller downwardly offset relative to the other rollers to lift the dolly as the dolly is inserted into one of the compartments; a locking mechanism adapted to lock the dolly into one of the compartments when the dolly is transported by the frame; wherein the dolly is configured to be removably received in one of the compartments such that as the plurality of wheels do not support the dolly when the dolly is received in the one of the compartments and the dolly is decoupled from the frame when removed from one of the compartments. 2. The system of claim 1 wherein the frame has an E-shaped base and defines two compartments.3. The system of claim 1 wherein the locking mechanism includes a pivoting lever disposed adjacent the compartments that is pivoted between a locked position and an unlocked position.4. The system of claim 3 wherein the locking mechanism further comprises an having a U-shaped actuator bar that shifts the pivoting lever to the locked position when the dolly is inserted into the compartment and pushed against the U-shaped actuator bar.5. The system of claim 3 wherein a manual actuator is provided on the frame for shifting the locking mechanism between the locked and unlocked positions.6. The system of claim 3 wherein the locking mechanism further comprises an elongate bar coupled to the pivoting lever and a link adapted to couple the U-shaped actuator bar to the elongate bar.7. The system of claim 1 wherein a plurality of guide elements are provided on the frame for guiding movement of the dollies into and out of the compartments.8. The system of claim 1 wherein the plurality of rollers have an axis of rotation extending in a direction from the front end to the back end and being secured to the frame.9. The system of claim 1 wherein the dolly is formed of polymeric material and includes hard inserts that engage the plurality of rollers.10. The system of claim 1 wherein the dolly includes a platform deck having a plurality of pockets, wherein each of the pockets is configured to receive one of the plurality of wheels of another dolly stacked on top of the dolly.11. The system of claim 1 wherein the dolly has a platform deck comprising an upper surface that is supported by a honeycomb body.12. A method of stocking a production line using a motorized truck having a towing adapter and a plurality of trailers having wheels that are provided with a towing hook and a hook receiver respectively on one of a front end or a back end, each trailer having two sides extending between the front and back ends, the trailers being accessible from at least one of the two sides to load a plurality of platforms having wheels onto the trailers for transporting a plurality of wheeled platforms on the trailers, the method comprising:loading a first set of wheeled platforms loaded with a plurality of parts onto the trailers from the side; actuating a locking mechanism by engaging at least one wheeled platform against a U-shaped member rotataby disposed on the frame, the locking mechanism being adapted to prevent transverse movement of the wheeled platform relative to the frame; transporting the trailers with the first set of wheeled platforms and parts carried thereby to the production line; unloading the first set of wheeled platforms one at a time from the side of the trailers; and loading a second set of empty wheeled platforms onto the side of the trailers one at a time to replace the first set of wheeled platforms. 13. The method of claim 12 wherein the towing hooks and hook receivers are not unhooked as the first and second sets of wheeled platforms are loaded and unloaded.14. The method of claim 12 wherein the loading and unloading steps are performed by rolling the first and second sets of wheeled platforms onto and off of the trailers through an opening in the side of the trailers.15. The method of claim 12 wherein during the step of transporting the wheeled platforms the wheels thereof are raised above the surface of the floor.16. The method of claim 12 further comprising unlocking the wheeled platforms prior to the unloading step to permit the wheeled platforms to be transversely moved relative to the trailers during the unloading step.17. The method of claim 12 further comprising lifting the wheeled platforms during the loading steps and lowering the wheeled platforms during the unloading step.18. A production line part stocking trailer assembly, comprising:a rack supported on a first set of wheels, the rack having a towing adapter at one end for attachment to a tow motor truck or another rack, the rack having a side opening and supporting members on opposite edges of the side opening; and a dolly having a second set of wheels, the dolly being adapted to be inserted and removed through the side opening and selectively carried by the rack, the dolly being temporarily disposed on the supporting members when carried by the rack with the second set of wheels being spaced from the ground, wherein the rack and the dolly have a locking mechanism for selectively locking the rack and dolly together when the dolly is carried by the rack, the locking mechanism having a pivoting lever and a U-shaped actuator bar pivotally disposed on the rack and adapted to actuate the pivoting lever to partially span the side opening to lock the dolly into the rack. 19. The production line part stocking trailer assembly of claim 18 wherein the supporting members are a plurality of rollers disposed on each edge of the side opening that are engaged by cooperative portions of the dolly that ride upon the rollers as the dolly is inserted and removed through the side opening.20. The production line part stocking trailer assembly of claim 18 wherein the rack has an E-shaped base having two side openings on one side and wherein the rack is adapted to carry two dollies.
