A storage vault 10 is described for reception within a subterranean bore 11. The storage vault 10 includes a vault casement 15 that releasably receives a carriage 21, a driver 42, and a control system 65 as an assembly therein. The driver 42 is situated axially alongside the carriage 21 and is utilized to extemd and retract, lifting the carriage 21 from a lowered, closed storage condition, to an upwardly disposed access condition, where individual compartments 24 become accessible to a user. The carriage 21 is situated below a lid 57 that is preferably carried on top of the carriage to be moved therewith between open and closed conditions. Motion of the carriage responsive to extension and retraction of the driver is controlled by first and second guides. The first guide is mounted between the carriage and the vault casement 15, while the second guide is mounted between the carriage and the driver 42. The first and second guides 34, 53 further assist in maintaining lateral stability of the carriage when it is in its upward, access position. Compartments are provided in the carriage at opposed ends for at least a portion of the control system circuitry and driver components to facilitate maintenance and repair.
