AI Technical Summary

Problems solved by technology

The pallet on this shelf is fixed on the support frame, and the height of the pallet is not adjustable. In order to facilitate the staff to load and unload the goods on the pallet, the height of the pallet on this shelf is designed so that the staff does not The height that can be reached by tools, because there needs to be a certain distance between two adjacent trays for placing goods, so the number of trays that can be installed on this shelf is small, the goods stored are less, and the height of the fresh vegetable storage is usually Higher, so this kind of shelf cannot use the upper space of the fresh-keeping warehouse, and the space utilization rate is low
