ABSTRACT:
A system is provided for transporting large glass sheets or blanks. A-frame stanchions are removably secured to a base section to form a rack for carrying stacks of sheets supported on edge upon the base. The base section is supported above the floor or supporting surface by spacer sections which define a corridor beneath the base for removably receiving a transport dolly. The transport dolly includes lift platforms positionable beneath frame members of the base section. Inflatable air bags are adapted to raise and lower the lift platforms for selectively raising the rack to permit it to be moved about on the transport dolly. A steerable wheel arrangement is provided at the forward end of the transport dolly. Stacking posts are provided at the corners of the base whereby when empty, the A-frame stanchions can be disassembled and the racks stacked in nested relationship for return shipment and storage.
