CARTON LIVE STORAGE
Carton live storage is suitable for products such as cartons that have smooth bases so they
can roll easily off the inclined rollers. Carton live storage saves a lot of space as it eliminates the
need for walkways and guarantees FIFO stock rotation and improved picking speed. Due to the
system mostly being used in order picking areas, a large number of different SKUs can be
positioned in a small run of aisle. This results in a reduction in the time needed, bringing greater
efficiency to the operation.
CAROUSELS
Carousels come in either vertical or horizontal styles. Each gives the opportunity to make
good use of the available floor space. They are usually controlled by a computer. Vertical
carousels are made up of shelves that are suspended between two chains that are controlled by
electric motors, allowing them to rise and fall. This means that the product is always at the ideal
ergonomic height for picking. With horizontal carousels the columns of shelves move left or
right, rather than up and down. They tend to be used for slightly larger products than vertical
carousels.
MINILOAD
Smaller items can be stored in an automated storage and retrieval system known as a
miniload. A miniload is implemented through a crane, with access to cartons or tote bins from
shelving or racking on either side of it. Miniloads are best suited for slow-moving goods with
wide product ranges. It is possible to adapt miniloads for higher throughput situations. For
example, with numerous shuttles operating on different levels within an aisle, bringing the goods
to a vertical lift at the end.
LONG LOADS
Long products can often prove difficult to store as the majority of racking systems are
unable to accept them, especially where the racking system uprights are narrower than the
product being stored. Long products such as steel rods, carpets and wooden boards therefore
need alternative storage methods.
One method is vertical storage, where items are stored in a ―toast-rack‖ fashion, upright
between storage modules. Another is pigeon hole racking, where the pigeon holes extend away
from the aisle far enough for the length of the product. Block storage is suitable for items such as
wooden boards, which can be strapped together and then stored in block with wooden separators
that allow them to be lifted from underneath.
