Pallet racking and commonly known as beam-shelf, or cargo-style shelves, usually heavy-duty shelves, warehouse shelves in a variety of domestic systems, the most common. Must first be assembled unit of work, about the packaging of goods and weight and other characteristics of group disk, determine the type of tray, size, size, and single-prop load and stack (Single prop cargo weight is generally less than 2000kg), then thus the span of the shelf unit, depth, spacing, according to the warehouse roof along the effective height and the largest fork lift truck high determine the height of the shelf.
　　Shelf unit span is generally less than 4m, depth 1.5m or less, low, high warehouse shelves a height of 12m or less, ultra-high warehouse shelves a height of 30m or less (type of warehouse automation are basic warehouse shelves by the total number of segments of high 12m or less column form). Such storage medium, low, high storage battery forklift mostly with Reach, Counterbalance forklift battery, three-way forklift access operation, the lower shelf can also be used when electric forklifts, ultra-high stacking machine with memory storage take the job. Such a high shelf system space utilization, access flexibility, combined with computer management or control, which can basically meet the requirements of modern logistics system. pallet racking is widely used in manufacturing, third-party logistics and distribution centers and other areas, both for multi-variety low-volume items, but also large quantities of varieties suitable for small items. Such a high shelf in the warehouse and warehouse in the most widely used ultra-high-bit (mostly automated warehouse shelves with such shelves).
