Abstract
A mobile storage system includes mobile carriages that roll on rails embedded in a building floor. The carriages are driven along the rails by at least two flanged wheels that engage a grooved rail. The flanged wheels are preferably mounted in parallel channels located at the center of the carriages. The flanged wheels are driven in synchronization by a sprocket and chain drive. Either electric or manual power may be provided. In both cases, the sproket and chain drive is adjustable to provide proper chain tension to the wheels to improve tracking. Chain adjustment may be accomplished by an idler sprocket movably mounted to a carriage channel.
