摘要： A transport and display cart is formed of light weight plastic and metal components including a base unit formed from an open framework in which is disposed and fastened a molded plastic tray. Wheels preferably including casters are provided on the underside of the base unit and opposed ladder units having horizontal bars or rungs are removably connected to opposed ends of the base unit by fitting within post supports rigidly connected to the base unit. Upper shelves include plastic trays that are constructed identical to the tray connected to the base unit and reinforcing rods having downwardly open jaws or hooks at their opposed ends for engaging the horizontal rungs or bars of the opposed ladder units. The upper shelves can be selectively disposed in horizontal or tilted positions simply by hooking the ends of the reinforcing rods over different rungs of the ladder units.
