A mast structure (28) for a storage/retrieval machine (10) wherein the mast is pivotally supported on a support structure (30) and temporarily secured by bolts (54) acting on the support structure and the mast, and the mast is moved above its pivot (52) by adjusting devices (56, 58, 64) mounted on the support structure and mast to obtain precise vertical alignment of the mast as determined by a plumb line or other known adjusting devices. In accordance with another aspect of the invention, adjustable connectors (78, 80, 82) are provided to join two previously aligned masts to define a double masted storage/retrieval machine.
