A pallet rack is a storage system designed to store items that are often bundled or palletized in a warehouse. Pallet racks come in many different styles and builds, but they all share the same function of increasing storage density in the warehouse. Pallet racks accomplish this by allowing a business to stack items vertically and use more space other than just floor space. The earliest pallet racks were patented back in the 1940s. Here is a brief guide to provide a better understanding of pallet racks.
Drive-in racking
This type of pallet rack system offers one of the highest storage density solutions for your warehouse. This design completely eliminates the need for aisle space, and it maximizes vertical and horizontal space. This type of system can increase storage capacity by up to 60%. The system works by allowing the lifting mechanism to drive through the rack structure rather than having a forklift driver travel through aisles and pick items off of the rack.
Push-back racking
This type of rack system increases the number of pallets that are stored on the same rack level. When one pallet is removed, the others fall back due to the force of gravity. A slight incline in the rack design creates this natural gravitational effect. These systems typically accommodate up to 6 pallets in depth on a single rack. This storage system utilizes a method called “last in first out” (LIFO).
Gravity flow rack systems
Flow racks use the force of gravity with metal rollers in order to increase the productivity flow of the warehouse. This system eliminates the need for aisles and increases the storage space of the warehouse dramatically. These systems are designed for the unique needs of each company and warehouse, so they are custom-fitted in order to achieve the greatest possible efficiency.
Carton Flow system
This type of system which is also called a span track works alongside pallet rack systems to increase the picking capability of the warehouse. The system reduces the number of personnel that perform picking operations, and it uses gravity and rollers to move items forward to pick positions. This could be described as a light-duty version of a flow rack system.
Angle Deflector
These objects are created to deflect impacts in areas that are susceptible to damage. They are placed on upright frames either by being bolted on or welded on during the manufacture of the rack system.
Most warehouses use some type of pallet racking system to accommodate their inventory and expedite picking operations. There are many designs from which to choose, so it pays to educate yourself about these systems. Keep abreast about the latest advancements and look for new ways to improve the flow of your warehouse.
