Storage of palletised materials would not be possible today without pallet racking structures. These structures have pallets or skids in which palletised materials are placed. There are many different types of pallet racks and all of them permit easier storage of palletised substances. These storage systems are used along with forklift trucks that deposit packed pallets on the racks. Today pallet racks are used by big industries, warehouses, retail stores and distribution centres. Their price ranges can vary based on the amount of storage needed. The bigger the space needed the higher the cost. There are a number of pallet racking systems that people commonly purchase. These include:
Drive through and drive-in – These types allow the forklift truck to drive directly into a storage bay (usually a lane of stacked rows). The drive-in system uses one position as the entry and exit point. Because of having only one entry/exit point it is a Last-In, First Out (LIFO) method of storage. Each bay is only used for one product type. The drive-through rack enables a forklift truck to enter from each side of the bay unlike the drive-in rack. Hence it uses a method of storage called First-In, First-Out (FIFO). This one can be loaded on one end and off-loaded on the other end, enabling a FIFO (First-In, First-Out) product rotation.
Selective pallet racking – This is the most commonly bought system as it is cheaper and offers easy access to all products. It can be bought when stock is quickly depleted and replenished. Many wholesale and retail stores use selective pallet racks. There are two styles: the roll-formed and the structural racking system. The former has a teardrop design. Pallets are laid on the horizontal beams that are in turn fastened together with movable clips that allow for easier height adjustments. Roll-formed selective racks are perfect for storing items of different sizes. Structural rack designs are almost similar to roll-formed only that their horizontal load beams are linked to the vertical frames with bolts. These can tolerate heavier material though. Because of the bolted fastening, the shelves can be dismantled or restructured the way you please.
Motorised mobile pallet racks – Alternatively called compact mobilized or mobile industrial, motorized mobile racks are made for warehouses. They are configured in way to reduce pallet storage space by half. They make fixed aisles more productive by building more rows of pallets onto sturdy rolling carriages. Then the set up is placed on floor tracks. With a remote control, pallet racks can be moved sideways along the floor tracks, forming a mobile floating aisle.
Gravity, dynamic or pallet flow systems – These are high density options that uses depth to increase storage area. It consists of an inclined/sloped rail with some rollers that enable loaded pallets to move smoothly along the slanted plane. They also feature braking systems that are used to regulate the speed of a moving pallet. They can be either LIFO or FiFO inventory handling systems.
