Why Is The Pallet Rack System So Important For An Effective Warehouse Storage Operation?
Pallet racks allow for the organized storage of goods and products in a warehouse operation. The racks provide for horizontal storage of pallets on multiple levels.
Pallet racks allow for the organized storage of goods and products in a warehouse operation. The racks provide for horizontal storage of pallets on multiple levels. Each pallet spot can be assigned a specific location and this information is input into a computer database along with the identity of the product being stored at the specific location. This information allows the company's personnel to know what products are being stored, how much of a specific product is in storage and where the product is kept.
The pallet rack system has several categories. The most popular is called the selective pallet racking system. There are three major configuration types ie the roll formed, the structural bolt and the very narrow aisle. The roll formed is also known as the teardrop rack because the holes in the column are shaped like teardrops. This allows easy adjustment on the horizontal load beams which are held in place by mounting clips. As stored items sizes change, the location can be adjusted to easily accommodate the different sizes.
The second type of selective pallet rack system is the structural. This system's load beams are held together by bolts so a much heavier weight of product can be stored safely. The structural system's upright columns can sometimes serve as support beams for the roof.
The final type of selective pallet racking is called the very narrow aisle and it is used where space is at a premium. A guide wire is located in the floor providing the tracking for the vehicle used to place or pull the stored items.
Some of the parts of the selective pallet racking system include load beams, upright frames, braces, pallet supports, wire decking, footplates, column protectors and guard rails.
Pallet Storage Rack Designs
Within the pallet rack system are different types of pallet storage rack designs. The four most common include the drive-in and drive-though racks, the push-back pallet racks, the pallet flow racks and the compact mobilized pallet rack.
The drive-in and drive-through involve the accessibility for a forklift. The drive-in has one entry way which also serves as the exit in the aisle between rack rows. The drive-through has an entry at one end of the aisle and an exit at the opposite end of the aisle.
The push-back pallet rack allows space to be utilized by depth instead of width. Multiple pallets can be stored behind each other. A pallet is stored on a wheeled cart that fits on rails and moves back as another pallet enters. The pallets are placed on these nested carts that are set upon inclining rails. Each pallet will move back when a new pallet is added to the front. When the pallet is removed, the remaining pallets will roll forward.
The pallet flow is structured with rollers on the bottom of a sloped storage rack. Adding a pallet to the rack causes the other pallets to move away from the incoming pallet. Removing a pallet causes the other pallets to move forward in the direction of the removed pallet.
The compact mobilized pallet racks can move along a floor track so that aisle space can be used for storage. This process eliminates the need for a forklift aisle between each rack. The racks can be moved as needed and open up a forklift aisle. Storage space can be increased substantially with this system.
