One of 10 similar units made for Ford Motor Company to receive stacks of trays containing instruments and deliver them to operators for assembly. The benefits were: avoidance of damage; security; dust and dirt exclusion and speed of presentation - less than 4 seconds.
The units were included within a system we installed which included carrying jigs around a circuit to each assembler and the infeed and outfeed of boxes and trays of components into the clean room where the instrument displays are assembled.
