The key to successful rack construction lies in understanding the different types of racks, materials, and load capacity requirements. With the right tools, expertise, and safety measures, you can build racks that meet your specific needs and comply with industry standards.
Types of Rack Construction
There are several types of rack constructions that are commonly used in various industries, based on the specific needs and requirements of the users. Each type of rack construction has its own set of advantages and disadvantages. Some of the most commonly used types of rack construction are:
1. Selective rack construction
The most popular type of rack construction is the selective rack construction. It is a versatile storage system that allows for easy access to every pallet. This type of rack construction is ideal for warehouses that store a wide variety of goods. The selective rack construction can be easily modified to accommodate any kind of pallet or load size and is available in a range of sizes and configurations, making it a highly flexible option.
2. Cantilever rack construction
The cantilever rack construction is ideal for storing long and bulky items, such as lumber, pipes, and steel bars. This type of rack construction has arms that extend out from the vertical column, which provides support for the load. The cantilever rack construction can be designed to fit any specific length requirement, and the height can be customized based on the user’s requirements.
3. Drive-in rack construction
The drive-in rack construction is an efficient storage solution that allows users to store a large number of pallets in a small area. This type of rack construction is suitable for warehouses that store large quantities of similar items and have a low turnover rate. The drive-in rack construction uses rails that run the depth of the rack system and are designed to accommodate pallets that are loaded and unloaded from the same side. This makes it a cost-effective option as it requires less aisles than other rack constructions.
The Importance of Proper Rack Construction
Proper rack construction is essential to ensure the safety and efficiency of a warehouse or storage facility. It is important to choose the right type of rack construction based on the specific needs and requirements of the user, as well as the specific characteristics of the goods to be stored.
The Consequences of Improper Rack Construction
If proper rack construction is not followed, it can lead to serious consequences, such as:
- Injury to workers: Improperly constructed racks can cause accidents that result in severe injury or death. Falling pallets, unstable racks, and improperly secured loads can all pose a risk to workers.
- Product damage: Rack failures can result in product damage or spoilage, which can be expensive for the user.
- Financial losses: Rack failures can result in costly repairs to the rack system, as well as the damaged products and property.
Proper rack construction not only ensures the safety of workers and products but also maximizes the use of available space, improves inventory management, and enhances the overall efficiency of a warehouse.
Types of Rack Construction
Rack construction can be classified into different types based on their configuration and design. Choosing the right type of rack is crucial in optimizing the use of space, enhancing handling efficiency, and ensuring safety.
The selective rack is the most common type of rack construction. It is a single-deep configuration that allows direct access to each pallet stored. Selective racks work best for applications that have a high level of stock rotation and a low volume of SKUs.
The double-deep rack is a two-row-deep selective rack configuration that allows the storage of two pallets deep on each side of the aisle. This type of rack construction provides a higher storage density and requires fewer aisles resulting in space optimization. However, it requires specialized lift trucks that can reach two pallets deep.
Drive-in rack is also a high-density storage system, where pallets are placed on rails that extend several pallets deep into the rack. This system allows forklifts to drive into the rack to pick or store a pallet. It works best for low stock rotation and high-volume storage.
Pallet Flow Rack
Pallet flow rack is a gravity-driven system that allows pallets to flow from the rear to the front of the rack for picking. This system is ideal for high-volume applications that require first-in, first-out (FIFO) inventory management. It requires less forklift traffic since it is gravity-driven and uses gravity to move pallets.
Cantilever rack is a unique type of rack system designed for storing long and bulky items such as pipes, boards, or lumber. It has arms that extend from the uprights, providing unobstructed access to the items stored. It is commonly used in manufacturing and lumber yards.
Push-back rack operates on the LIFO (Last-In-First-Out) inventory management method. It allows for multiple pallets to be stored up to six pallets deep on both sides of the single aisle. The rack is tilted so that pallets move towards the front for picking as new pallets are added from the back. This rack configuration provides a high-density storage system with fewer aisles while maintaining individual SKU selectivity.
Mezzanine rack is a type of rack system designed for vertical expansion. Mezzanine rack uses the unused overhead space to provide additional levels of storage. It is usually built over the existing work area to create extra storage space without disrupting the ongoing operations.
