Space utilization characteristics and optimization methods of heavy-duty shelves The space utilization of heavy-duty shelves is centered on "vertical expansion", which fully excavates the vertical space of the warehouse by raising the shelf height. The conventional height can reach 8-15 meters, and some high-level heavy-duty shelves with stacker cranes can even exceed 20 meters in height, which can increase the warehouse space utilization rate to 50% -70%. However, due to the storage and retrieval needs of overweight goods, the width of the aisle needs to be wider than that of ordinary shelves, usually 4-5 meters (suitable for heavy-duty forklifts), resulting in a significant occupation of ground space. Optimizing space utilization can be approached from three aspects: firstly, adopting "double deep heavy-duty shelves", setting up two layers of shelves on both sides of the same channel to reduce the number of channels; The second is to flexibly adjust the floor height according to the height of the goods, for example, when storing equipment that is 3 meters high, the floor height is set to 3.3 meters to avoid waste; The third is to store low turnover overweight goods on the upper shelf and high-frequency turnover goods on the lower shelf, achieving a balance between "space and efficiency", especially suitable for heavy industrial warehouses with high floor height and tight ground space.
