Shuttle storage systems are used to store or to buffer totes, cardboard boxes and shelf boards. Static line racks are referred as shuttle storage system, in which autonomous shuttle vehicles operate. Every single shuttle vehicle operates in one or in several rack levels, but not in all. Shuttles, which operate in several rack levels, feature a lifting function. Vertical conveyors are used to connect the rack levels. Those can either relocate the shuttle vehicles in another rack level or convey the load to the level of the pre-storage area. Shuttle storages are used preferably for highly dynamic applications and are assigned to the automated small-parts warehouses. Thus, they represent an alternative to the conventional storage system with lifting beams – or miniloads. Advantages arise with the possibility to scale the performance of the system by varying the number of shuttles. Hence, it can be reacting to peak demands and changeable capacity utilisations. The loading is done by load handling devices (LHD), as they are known from the miniloads. However, the LHD are optimised in reference to the application of shuttle systems. Therefore, the flexibility concerning different goods is given. Depending on the LHD different rack types must be used.
