Light weight pick cart
Various configurations of light weight pick carts are disclosed; some embodiments may alternate between a first configuration having two shelf racks and a second configuration having both a shelf rack and a flatbed. A first shelf rack has multiple accessory support units attached, having multiple different configurations to facilitate holding differing shapes, sizes, or weights of accessories. Swivel casters and multiple handle locations can enhance maneuverability; and proper selection of material and use of perforation and wire frames may reduce weight to ease operation. For stability, a removable second shelf rack may engage the first shelf rack using hooks, while a removable flatbed unit may engage the first shelf rack using notches. The second shelf rack provides more discrete storage locations, while the flatbed permits transportation of larger or heavier items. This versatility enhances the utility of the cart.
