Choosing a suitable crossbeam rack requires comprehensive consideration of its own cargo characteristics, warehouse conditions, operational needs, etc. The following are key purchasing guidelines: 1、 Clarify the core characteristics of the goods Weight and specifications Determine the weight of a single pallet of goods (including pallets) to match the load-bearing capacity of each layer of the shelf (conventional 500-5000kg, customized can exceed 10 tons), in order to avoid safety hazards caused by overloading. Measure the external dimensions of the goods (length x width x height) and pallet specifications (such as 1200 x 1000mm, 1100 x 1100mm, etc.) to ensure that the length of the shelves' crossbeams and interlayer spacing can adapt to the goods, and reserve a safety gap for forklift access (recommended to be ≥ 100mm on one side). storage type If it is heavy goods (such as mechanical parts, metal materials), thick columns and high-strength beams (such as welded beams) should be selected; If it is a lightweight boxed cargo, it can be paired with plywood or mesh to enhance stability. 2、 Adapt to warehouse space conditions Warehouse size and layout Measure the actual length, width, and net height of the warehouse (excluding obstacles such as fire pipes and lighting fixtures), determine the total height of the shelves (regular high position ≤ 12m, super high position ≤ 30m) and layout (such as single row, double row, and wall mounted placement). Reserved forklift aisle width: Plan the aisle according to the forklift type (3-4m for balanced weight forklifts and 2.5-3m for forward moving forklifts) to ensure smooth operation. Ground bearing capacity Check the ground load-bearing data of the warehouse. If the ground load-bearing capacity is insufficient (such as in an old warehouse), it is necessary to communicate with the manufacturer to increase the shelf base or ground reinforcement plan to avoid shelf settlement and deformation. 3、 Match operating devices and processes Type of operating equipment If using a forklift (including counterweight, forward moving, stacker, etc.), it is necessary to clarify the lifting height and maximum operating width of the forklift, ensure that the shelf height matches the lifting capacity of the forklift, and the channel width meets the turning radius of the forklift. If there are plans to introduce automated equipment (such as AGVs) in the future, it is necessary to communicate with the manufacturer in advance about the compatibility of shelf interfaces and reserve space for sensor installation. Access frequency and method If goods are frequently accessed and multi category turnover occurs (such as in e-commerce and supermarket warehousing), priority should be given to designs with adjustable floor height and independent storage locations for easy and quick positioning of goods; If it is for batch storage and low-frequency turnover, the interlayer spacing can be optimized to reduce space waste. 4、 Focus on safety and durability Material and Craftsmanship It is recommended to choose Q235 or Q355 high-strength steel for columns, and use lap welded beams or C-shaped steel for crossbeams. The surface should be treated with acid pickling, phosphating, and electrostatic spraying to enhance rust prevention ability (especially in humid environments where anti-corrosion needs to be strengthened). Check the connection details: The connection between the crossbeam and the column should be equipped with self-locking safety pins, and the bottom of the column should be equipped with anti-collision feet to avoid structural looseness caused by forklift collisions. compliance Choose a manufacturer that has passed ISO9001 quality certification, and the shelf design must comply with the "Design Specification for Storage Shelves" (GB/T 28576-2012) to avoid using unqualified low-priced and inferior products.
