Abstract: A multi-level storage facility comprising a plurality of vertically stacked storage chambers, each of a size to accommodate an item to be stored, such as a vehicle. Each chamber contains a platform, and all of the chambers are accessible from a common face of the facility. An elevator is mounted so as to move along the common face of the facility to provide access to any one of the chambers. Each of the chambers and the elevator provide a device for engaging one of the platforms in an upper or a lower position. The platform being movable between positions at any time including when the elevator is in motion. With the elevator aligned with any one of the chambers, the platform in the chamber may be exchanged with one on the elevator. The elevator provides a device for acheiving this result, saving the extreme expense of having exchange devices in each and every chamber, or on each platform.
