Abstract: A pallet to support a component device for processing and testing, the device being removably secured to and upon the pallet for translation from a mounting station through one or more processing or assembly stations and optionally to a testing station, for elevation and lowering at the testing station, and for translation to a repair or discharge station, on conveyor devices moving the pallet by friction drives or other means. The pallet is made substantially entirely of a very tough nylon resin or equivalent plastic material. In one of its preferred forms the pallet comprises a grid body, an upper support plate member, a lower driven plate member and bumper bars on the side edges of the pallet. In a second preferred form the pallet comprises a grid body and an upper support plate member; and in a third form the pallet comprises a unitary molded grid body closed on its bottom side except for drain and bolt openings therethrough. The second preferred form of pallet can also be molded as a unitary device.

Abstract: A plastic material handling rack adapted to receive and translate small or relatively large parts or units, capable of being stacked vertically one rack upon another, and to be loaded by conventional fork lift trucks into transportation vehicles. The plastic material handling rack is assembled with corner posts, side rails and end rails that form the unit into a rectilinear framework. A floor plate is removably attachable to the framing. Transverse rails are attached to the side or end rails for support of larger machine units or devices, and solid or perforated side walls are attachable to the corner posts and upon the side rails and end rails, converting the open framework of the rack into a tub rack.
