A mobile storage system including a plurality of one-piece track members each defining a guideway and a series of longitudinally spaced holes. The system also includes a carriage rotatably supported on the track members on rollers riding in the guideways. A drive mechanism on the carriage includes a sprocket which directly engages the unitary holes in each track member. In a preferred embodiment for heavy units, the drive mechanism includes a pair of such sprockets mounted on a common shaft driven at a midpoint to reduce carriage canting.

A mobile storage system for movably supporting at least one mobile storage unit, wherein said system comprises: at least three spaced apart track members including first and second outer track members and an inner track member disposed intermediate said outer track members positioned in parallel relationships with each other, each track member being formed as a unitary piece and including an upper surface having a series of openings which are aligned longitudinally along the length of each track member; a plurality of support structures including first and second outer support structures and an inner support structure wherein one support structure is movably mounted upon each said track member for movement along the length of its respective track member, each support structure including means for supporting the mobile storage unit; a first axle rotatably mounted to said support structures extending transversely across said first outer track member, said inner track member and said second outer track member; a plurality of driving sprockets wherein at least one driving sprocket is fixedly mounted on said first axle for co-rotation therewith, each of said driving sprockets disposed in adjacency to one of said track members and having teeth in driving engagement with the series of openings in the track member; a drive shaft extending substantially parallel to said first axle having a first end portion rotatably mounted to said first outer support structure and a second end portion rotatably mounted to said inner support structure; first drive means disposed adjacent said first outer support structure for rotating said first end portion of said drive shaft; and second drive means in operative association with said second end portion of said drive shaft and with the midsection of said first axle, whereby rotation of said drive shaft is drivingly transmitted to the midsection of said first axle and said driving sprockets are rotated so that said mobile storage unit is moved along the lengths of said track members.
