Load bearing capacity and specification division of fluent shelves Fluent shelves are positioned as "light and medium-sized storage", and their load-bearing capacity is closely related to the material, spacing, and shelf structure of fluent shelves. The regular single fluent strip can bear a weight of 50-150kg, and the single-layer overall weight can bear 200-800kg, suitable for containerized goods (such as cardboard boxes, plastic boxes) and small and medium-sized components (such as electronic components, hardware accessories); The heavy-duty model uses thickened fluent strips (with metal rollers and thickened brackets) and increased roller spacing, with a single strip bearing capacity of 200-300kg and a single-layer overall bearing capacity of 1000-1500kg. It can store small pallet goods or heavy-duty parts boxes. The specifications are divided according to the number of layers and length: small fluent racks (2-3 layers, length 1.2-2m), suitable for small warehouses or workshop workstations; Medium sized fluent rack (4-6 floors, length 2-3m), used for picking areas in e-commerce and retail warehouses; Large fluent shelves (6 floors or more, length 3-4m), used in conjunction with the top shelf platform to improve vertical space utilization, commonly found in manufacturing raw material storage areas.
