Abstract: Storage structures are disclosed in which lifts carry articles to be stored, such as motor vehicles to be parked, from entry level to storage levels. Each lift comprises sets of endless elements such as chains which carry platforms. Each platform is permanently attached to one set of endless elements. Each platform is releasably attached to the other set of endless elements whilst that platform is in the operative run of the lift and is horizontal. When the platform is in the inoperative run of the lift it is vertical. Rotatable rings or reciprocating shuttles, with bays for temporarily accommodating articles, move the articles between the lifts and storage bays provided at each storage level.
