Key parameters and calculation basis for the design of crossbeam shelves The design of crossbeam shelves should revolve around three key parameters: cargo characteristics, equipment parameters, and spatial conditions. Firstly, the load-bearing capacity of the shelves should be determined based on the weight of the goods. For example, if a single pallet of goods weighs 1500kg, a single-layer load-bearing capacity of ≥ 1800kg should be designed (with a safety factor of 1.2 times reserved); Secondly, the total height of the shelves is determined based on the lifting height of the forklift. The lifting height of a conventional balance weight forklift is ≤ 6 meters, while that of a high-level forklift can reach 12 meters. The total height of the shelves needs to be 0.5-1 meter lower than the maximum lifting height of the forklift, with reserved operating space; Furthermore, the shelf span should be determined based on the size of the pallet, such as 1200mm × 1000mm pallet. The shelf span (beam length) should be set to 1200mm to ensure stable placement of the pallet. When designing, it is also necessary to calculate the spacing between columns, which is usually matched with the length of the crossbeam. For example, for a crossbeam with a span of 1200mm, the spacing between columns is set to 1200mm to avoid uneven stress on the crossbeam. In addition, the warehouse floor height and fire safety requirements need to be considered to ensure that the distance between the top of the shelves and the ceiling is ≥ 0.5 meters, which does not affect the use of fire protection facilities.
