Shuttle

is an autonomous storage vehicle that moves independently on the beams of a storage rack. It is supplied with power by batteries, power caps or via conductor rails and has a load handling device. A distinction is made between systems in which the S. transfer the storage units to vertical conveyors (e.g. elevator or lifting station) and systems in which S. are stored and retrieved, possibly including their load, via a vertical conveyor.
