Various types of gear and equipment for different military divisions are often stored in security cages, which are padlocked. In this installation, gear cages were installed on mobile carriages that move back and forth on top of rails in order to eliminate empty aisles and save space.
Both a powered mobile system and a mechanically assisted (operated by a hand crank) mobile system were installed to house gear. The powered units are used by the “owners” of the warehouse, who access the gear quite a bit more than the "tenants." The "tenants" are made up of different departments that need storage space more temporarily and/or they access it infrequently enough that it can be stored off-site.
