Wide Aisle Racking is one of the most common pallet storage systems in the world. It is an extremely versatile and cost-effective form of racking that can be utilised without the need for specialised handling equipment or driver training. This form of racking is constructed in single or double runs, which are separated by a wide aisle allowing 100% selectivity of products.
A very narrow aisle (VNA) racking system is often a potential solution for warehouses where space is at a premium.
VNA racking utilises Adjustable Pallet Racking (APR). It provides storage for a higher concentration of pallets, by reducing the aisle width to between 2.7 and 1.6 meters. This type of racking configuration requires the use of reach trucks, articulated forklift trucks, very narrow aisle or turret trucks to deposit and access pallets.
Double deep racking combines standard pallet racking components with a specialist forklift truck attachment to allow pallets to be stored two deep, as well as back-to-back, thereby removing the number of aisles required when compared to a standard single-deep solution. Generally, the products stored in each of the two locations would be the same; and since the front pallet will need to be removed to access the rear pallet, the last-in-first-out principle applies.
Mobile racking can be an excellent option when floor space is at a premium. It looks and operates like standard racking, but is mounted on mobile bases, so the structure moves left to right, reducing the number of aisles required.
Drive-in racking is an ideal solution when high-density storage is required. It is very similar to block stacking, as pallets are stored on cantilevered rails. Thereby making the loading and retrieval of pallets simpler, but also prevents goods from becoming damaged.
This system enables more pallets to be stored per cubic metre than any other storage system available on the market. Stock rotation is however limited, so the system is best suited to the storage of seasonal goods or bulk goods of the same type.
A pallet shuttle system is a high-density, compact storage solution that utilises remote-controlled, powered satellites to lift, move and place pallets within the rack. Due to the use of the in-rack satellite, pallets can be retrieved from any level, at any time, resulting in a much higher level of selectivity when compared with other dense storage solutions.
