Multitasking Model Drawbridge comprises tilt-up shelves, supported and lift assisted by gas-charged struts. As shelves are cleared of inventory, they can be raised up and out of way, providing access to items on successive lower levels. Used as cart with casters or as stackable rack when equipped with appropriate feet and receptacles, model is suited for over-the-road shipping, intra-facility part conveyance, safeguarding fragile components, and synchronized build operations.
