       Disclosed is a transport cart designed for moving
materials to and from manufacturing workstations.  It provides a
fixed bottom platform and three moveable shelves.  The shelves are
adjustable for vertical spacing, they are hinged at one end so they
may be successively tilted up 90 degrees providing access to the next
