Pallet racking are shelves used to store pallet goods, with strong load-bearing capacity and belong to a type of heavy-duty shelves. Pallet racking can also be called crossbeam shelves, mainly composed of column pieces and crossbeams. Although the structure is simple, the advantages of the structure are very significant. Pallet type shelves are safe, firm, and reliable, with a simple and beautiful structure. They can be adjusted and installed according to the site conditions, and the entry and exit of goods are not affected by the order of entry and exit. They are convenient and efficient, and are widely used in the storage mode of palletized goods and mechanical access by forklifts; The column pieces of the pallet shelf are connected with the columns, cross braces and slant support by bolts. The column and welded crossbeam adopt a plug-in combination structure to form the shelf frame, and the crossbeam is fixed with safety pins between the columns. This structural method is not only convenient for transportation and handling, but also allows for free adjustment of the height of each layer of the shelf space according to the height of the goods at 75mm or 50mm steps, meeting the storage requirements of different goods at different heights; The pallet type shelf can determine the layer load requirements according to the size of the column and beam specifications. The beam adopts a C-shaped buckle beam structure, which has the characteristics of large inertia moment, strong layer load capacity, strong impact resistance, light weight, and low cost; The plasticity of tray type shelves is very high. Based on tray type shelves, drawer type mold shelves, attic shelves, narrow aisle shelves, double depth shelves, pressed in shelves, automated three-dimensional warehouse shelves, etc.
