Our Virtual Showroom provides an overview of each rack storage system and their typical applications. These rack systems include:
- 100% Selective
- Double Deep
- Very Narrow Aisle Storage
- Flow Systems
- Push Back Systems
- Drive In Systems
- Cantilever Rack
Selective Pallet Rack
100% Selective Rack is the most common type of storage system for palletized products. Rack bays are positioned such that every pallet position is directly accessible. Selective pallet rack is commonly found in every type industrial facility, warehouse, distribution center, and big box stores. RIDG-U-RAK's selective pallet rack systems consist of fully welded uprights, roll formed beams, row spacers, pallet supports, and various other accessories.
Double Deep Pallet Rack
Double deep pallet rack systems offer greater storage density than selective rack. Using the same pallet rack components, rack bays are arranged two-deep and positioned back-to-back reducing the number of required aisles. Double deep storage is typically used in warehouse and distribution centers, where full pallets of like products are stored in the front and rear position. This application reduces selectivity. A deep-reach lift truck is typically used to access the rear pallet position.
Very Narrow Aisle Storage
Very Narrow Aisle Storage is a special application of selective rack. Aisles between rack bays are reduce to approximately five feet wide creating additional storage space. These systems great improve storage density, while maintaining 100% selectivity with access to every pallet position. VNA systems are used for both full pallet and carton storage. In either case, special lift equipment; such as turret trucks or order pickers are commonly used. For carton storage and retrieval applications, a special Man Up lift is used to hand pick items.
Flow Rack Systems
Gravity Flow are high density "First In, First Out" rack systems. Rollers and brakes are commonly used to feed pallets down an incline to a staging or picking operation. Systems are multiple levels high, and multiple positions deep. Flow rack systems provide an effective storage option for applications involving a low number of SKUs and high inventory turns, and are useful when storing time sensitive products.
Drive-In rack systems are very high-density last-in, first-out storage solutions. These storage rack systems feature narrow pallet-storage lanes running perpendicular to the working aisles. Pallets are placed on continuous rails. Drive-In systems are an economical solution when the need for density is high, and selectivity is low. As a result, they are most effective when storing many pallets of few SKUs. Ridg-U-Rak’s Drive-In pallet storage racks are available in either roll-formed and structural “space-saver” rails.
Push Rack Systems
Push back pallet rack systems store pallets of the same product on a system of carts-on-rails in lanes two to five positions deep. Pallets are loaded by “pushing back” previously placed pallets, setting the new pallet on the next cart position. Similarly, as a pallet is retrieved, the next pallet rolls forward to the aisle. Push-Back high density storage offers increased selectivity, as every lane can be accessed from the aisle without affecting the lanes above or below.
Cantilever Rack Systems
Unlike pallet rack, cantilever storage rack systems feature arms extended from one or both sides of structural steel towers allowing unobstructed, frontal access to all items. These systems provide full use of space, side-to-side on each level to store products or materials of varying lengths without interference. Cantilever rack is ideal for long or awkward shaped items like lumber, pipe, bar stock, carpet, furniture, and more.
