Types of Pallet Racks
Selective Pallet Racking
Within the selective pallet racking system, each pallet rack position remains easily reachable via the aisle. This configuration stands as the most prevalent choice, allowing for the extraction of a pallet from the shelving without necessitating the relocation of other pallets. This design ensures that every item remains readily visible for both loading and unloading, ensuring effortless access.
Furthermore, during inventory processes, there’s no requirement to disassemble items from their pallets, streamlining the counting and calculation procedures, thereby enhancing efficiency.
Double Deep Pallet Racking
Double deep pallet racking serves as an optimal solution for warehouses grappling with limited space and the need for swift handling. This system is particularly well-suited for implementing the First In, Last Out (FILO) warehousing approach. In essence, double deep pallet racking closely resembles selective racking, except for one key distinction: instead of accommodating a single pallet on a shelf, it accommodates two pallets, one positioned in front of the other.
The arrangement involves situating one rack closely behind another in such a manner that the initial pallet placed onto the shelf is subsequently pushed back, positioning it behind a second pallet that’s also stored on the same shelf. To extract the second pallet, a specialized forklift is required, given its location a full rack’s width behind on the shelf. By minimizing the number of aisles required, double deep pallet racking optimizes the utilization of available space in the warehouse.
Push Back Pallet Racking
Push back pallet racking emerges as the optimal choice for maximizing storage density in situations where space is at a premium. This system closely resembles the double deep system but distinguishes itself by accommodating far more than just two pallets on a shelf. Pallets are placed onto carts or shelf trays that smoothly glide on rails integrated into the rack frame, enabling easy pushing back when a new pallet is loaded onto the shelf.
The push back pallet racking system boasts the flexibility to handle pallets of various sizes, allowing for storage depths of up to six pallets. It proves particularly well-suited for implementing the Last In, First Out (LIFO) warehousing approach, offering efficient and space-saving storage solutions.
Drive In Drive Through Racking
Drive-in and drive-through racking systems cater to warehouses managing dynamic and frequently changing inventories. Unlike static systems featuring rows and aisles of racks, these systems prioritize compact placement, optimizing the utilization of the available space.
Within the drive-in or drive-through system, forklifts navigate within the racks, which lack designated lanes between the rows. The forklifts enter and exit through the same designated opening. This configuration proves especially advantageous for cold storage facilities where only a single entry point is permitted, facilitating efficient and space-conscious storage solutions.
Pallet Flow Racking
Pallet flow racking, also referred to as gravity flow racking, employs roller tracks to create a gravity-driven lane. These tracks are inclined, facilitating the smooth movement of pallets from the rear to the front of the rack. Within the system, brakes are strategically integrated to regulate the speed at which pallets move, ensuring secure handling. A pallet flow racking setup typically spans a considerable space, accommodating anywhere from two to twenty pallets on its tracks.
Similar to some other racking systems, the pallet flow racking system is specifically tailored for warehouses dealing with space constraints and adheres to a First In, First Out (FIFO) approach. It proves particularly well-suited for time-sensitive or perishable products, offering an efficient storage solution.
