Matching the load-bearing classification and applicable scenarios of heavy-duty shelves The load-bearing capacity of heavy-duty shelves is divided into multiple levels according to actual needs, and different levels correspond to different application scenarios. Primary heavy-duty shelves (5000-8000kg/layer) are suitable for storing small and medium-sized industrial parts, such as automotive gearboxes and motor components, and are commonly used in finished product warehouses of automotive parts factories; Intermediate heavy-duty shelves (8000-15000kg/layer) can carry large molds and machine tool beds, suitable for raw material storage in mechanical manufacturing enterprises; Advanced heavy-duty shelves (15000kg/layer or above) are mostly customized and used to store heavy steel and large equipment, such as pipe storage areas in steel plants and excavator parts warehouses in construction machinery factories. The weight-bearing classification should be determined based on the weight, volume, and frequency of storage and retrieval of the goods. For example, for heavy goods with high-frequency turnover, a slightly lower weight-bearing but more flexible structure will be selected to facilitate quick operation of the forklift; For overweight goods stored for a long time, priority should be given to shelves with high load-bearing capacity and stability to ensure long-term safety.
