A pair of stanchions are provided with a system for supporting a plurality of rows of pipe next to the stanchions such that the length of pipe is generally parallel to the plane of the stanchions. A pair of upright guides are coupled to the pair of stanchions respectively and a frame is coupled to the pair of guides for movement to different levels along the pair of guides. The frame comprises a pair of endless chains adapted to rest across the top row of pipe. Each chain has a plurality of feet attached thereto for engaging the pipe on which the pair of endless chains rest for moving pipe when the chains are driven. A driving system is provided for driving the pair of endless chains in unison in first or second directions for moving the pipe toward or away from the pair of stanchions.
