The weight capacity of pallet racking systems can vary depending on several factors, including the type of racking, its configuration, and the specific design and specifications of the manufacturer. Here are some general guidelines:
1. Standard Selective Pallet Racking: This is the most common type of pallet racking. It consists of upright frames and horizontal beams that create individual levels for pallet storage. The weight capacity per pair of beams (two beams supporting one pallet) typically ranges from 2,000 to 5,000 pounds (900 to 2,300 kilograms), depending on the beam length, profile, and gauge of steel used.
2. Double-Deep Racking: This system allows for two pallets to be stored back-to-back on each level. The weight capacity per pair of beams in double-deep racking is generally lower than that of standard selective racking due to the increased load-bearing requirements. It typically ranges from 1,500 to 3,500 pounds (680 to 1,600 kilograms) per pair of beams.
3. Drive-In/Drive-Through Racking: These systems are designed for high-density storage, where forklifts can drive directly into the rack structure to place or retrieve pallets. The weight capacity of drive-in/drive-through racking is influenced by factors such as the number of pallets deep, the height of the structure, and the spacing between upright frames. The weight capacity per pair of beams ranges from 1,500 to 4,000 pounds (680 to 1,800 kilograms) or more.
It's important to note that these weight capacities are general guidelines, and it's crucial to consult the manufacturer's specifications and guidelines for the specific pallet racking system being used. Additionally, factors such as the quality of the racking components, the condition of the floor and the levelness of the installation can also affect the overall weight capacity of the system. Therefore, it's advisable to work with a professional engineer or a qualified racking supplier to ensure that the racking system is designed, installed, and loaded within the manufacturer's recommended weight limits for safe and efficient operation.
