Narrow aisle systems are the giants among multi-position racking systems. They have the performance characteristics of multi-position racking at heights over 10 m and are free-standing. Reduced requirement for working aisles and extremely high lift heights are their distinguishing features. Narrow aisle systems are used specifi-cally where a) the space is limited and b) it is necessary to increase throughput compared with multi-position racking. Here, narrow aisle stackers (rail or induc-tive guidance with the choice of auto-matic height selection) or rack servicing cranes (RBG) are utilised. High rack stackers (rail or inductively guided) with automatic height selection or rack servicing cranes (pages 18 and 19) take on stacking and retrieval oper-ations. Availability is ensured by canti-lever arms at the head of the racking aisles.high racks are free-standing. They are not a permanent part of the building and thus extremely adaptable during possible reorganisa-tion.
Advantages:Exnt space utilisation
High throughput performance
Low working aisle widths
Gradual upgrading possibilities
up to fully automatic operation
