Selective Pallet Racking
Selective racking offers 100% unobstructed access to each and every pallet stored within the system. But there is a noticeable trade-off in storage density in comparison to other systems available. The greatest advantages of utilizing a selective rack system vs. floor stacking is that it accommodates the greatest number of SKUs, all stock is visible and immediately accessible, and the possibility of product damage is greatly reduced.
Deep-Reach Pallet Racking
If more storage spaces are required above what a selective system can yield, then you may want to consider a double reach system. It reduces the number of aisles, thus adding more pallet positions — but at the expense of reducing your pick selectivity. Another disadvantage is that it requires a special reach type of fork truck which, if not already a part of your truck inventory, obviously adds an additional cost.
Push-Back racking systems use a series of mobile carts that ride on rails within each pallet row. A loaded pallet is placed on the upper cart within the system. When another loaded pallet is loaded into the same bay, it pushes back the first loaded pallet. This process continues until all the trays (usually 3-4) are utilized. This system offers a highly dense storage solution when space is at a minimum and when the total amount of product to be stored is small and consistent in size and weight.
Cantilever shelves are particularly suitable for storing long loads. The light and heavy versions of this system offer the possibility of locating the levels (arms) on one or both sides of the fully independent structure. Cantilever shelving is ideal for the storage of beams, profiles, pipes, timber, etc.
Pallet Flow Racking
Pallet Flow provides superior density over all other systems and offers superior FIFO capabilities. The product is loaded at one end of the system, then flows to the other end to be unloaded. It also offers better product selectivity than either Drive-In or Push-Back. However, as with others, this system works best with a very limited number of SKUs. Moreover, it is the most expensive rack system by far. Potential lost pallet positions again come into play because the system is not level, due to the height and pitch of the flow rails that are inherent to the system.
Carton Flow Racking
Carton Flow systems separate picking and stocking aisles for full cartons and split cases to save up to 75 percent of labor costs compared to a static storage solution. Made up of slightly inclined wheel and roller platforms, the goods are deposited at one end to slide safely and gradually down to the picking aisle. The carton flow system provides in-stock visibility so pick aisles are kept full and restocking can occur simultaneously. First-in/first-out (FIFO) traffic minimizes shelf time and keeps inventory fresh.
A Drive-In System will definitely yield many more pallet positions than a Selective or Double Reach system (approximately 1200 vs. approximately 800 for the selective system, based on a building size of 9630 square feet, four pallets high, 10’ aisles). However, it again further reduces your pick selectivity and it offers little or no FIFO (First In / First Out) capabilities. A Drive-In / Drive Thru system is an excellent choice if there are no FIFO issues, if you are storing a very limited number of SKUs, and if the pallet and load heights, widths, depths, and weights remain relatively uniform to allow for consistent load rail heights
Pick Module Racking
Pick Modules are engineered racking systems that integrate different storage solutions inside multi-level work platforms that move product efficiently through a distribution facility. Capable of fulfilling over one hundred thousand orders per day or processing millions of units in a week, distribution centers consisting of hundreds of thousands of square feet, have become commonplace in UNARCO engineered design. Pick Modules use pallet rack to support the miles of conveyor and product flow systems, thereby reducing congestion and costly pick errors.
