Courtesy of Remstar Vertical Carousels Vertical Carousels consist of a serious of horizontal trays on a vertical carousel. Vertical carousels are most effective when floor space is at a minimum and there is ample overhead clearance. Enclosed vertical carousels offer additional security and protection for the product stored in them. Vertical carousels are frequently used in laboratories, offices, and specialty manufacturing operations. Application would be similar to a vertical carousel.
Disadvantage is a slower retrieval speed than a carousel.
A system of rows of rack, each row has a dedicated retrieval unit that moves vertically and horizontally along the rack picking and putting away loads. Guidance system may consist of a wire embedded in the floor, special tape, laser and optical system. Most effective where highly repetitive tasks are performed over extended distances. This is another version of an AGV that has added functionality to raise and lower the pallet to allow the transfer pallet loads into and out of pallet racking or to other equipment at different heights.
