Vertical carousels are very similar to vertical lifts because both storage systems use the same kind of advanced robotic technology. The difference between vertical carousels and vertical lifts is this: vertical carousels moves all the items when retrieving, while the vertical lift module only retrieves the desired item, which does not affect the rest of the stored items. What is the advantage of vertical carousel storage? Vertical carousels maximize the use of floor space by turning unused air space into storage space. Vertical carousels dramatically increase productivity, by up to 600%. Vertical carousels improve inventory management control. Vertical carousels also have lockable doors with password protected access key pads, which provide high security for valuable stored items.
