Figure 5.39 Wire-guided turret truck (Verizon,Atlanta, GA)

Unlike the automated machine, the hybrid truck is not captive to an aisle but may leave one aisle and enter another. Present models are somewhat clumsy outside aisles, but they operate within aisles at a high-throughput rate. Hybrid storage/retrieval vehicles operate in aisle widths ranging from 5 to 7 foot, allow rack storage up to 60 feet high in a rack-supported building, and may include an enclosed operator’s cab that may be heated and/or air conditioned. Sophisticated hybrid vehicles are able to travel horizontally and vertically simultaneously to a load position. The lack of flexibility, the high capital commitment, and the high dimensional toler ance in the rack are the disadvantages of hybrid storage/retrieval vehicles.
