There is no fixed standard for the load-bearing capacity of drive in shelves, which needs to be customized according to design specifications, materials, and structures. The core is divided into two categories: "single pallet load-bearing" and "overall load-bearing": 1. Single load capacity: The conventional range is 500-3000kg, designed according to the weight of the goods (including pallets). For storing light parts, choose 500-1000kg/pallet, and for storing heavy building materials and mechanical parts, choose 1500-3000kg/pallet. The crossbeam should be matched with the load capacity level (with a safety factor of 1.2 times reserved); 2. Overall load-bearing capacity: Due to the height of the shelves (usually 4-8 meters), the number of floors (mainly 3-5 floors), and the load-bearing capacity of the ground, structural calculations are required to ensure overall stability and avoid local overweight that may cause column deformation or shelf tipping. The design will be adjusted based on the warehouse floor load-bearing data.
