High space utilization: It can store multiple rows of goods along the depth direction, reduce the number of channels, and increase warehouse storage density by 30% -50% compared to ordinary shelves, suitable for scenarios with limited space. Large storage capacity: A single set of shelves can accommodate more goods of the same type, especially suitable for storing bulk and few variety goods (such as food, home appliances, etc.), reducing the cost of inventory dispersion management. Cost optimization: reducing the number of shelf groups and channel construction, indirectly reducing shelf procurement, installation, and warehouse land/rental costs, and lowering unit storage costs for goods. Relatively convenient to operate: With equipment such as forklifts, deep goods can be quickly accessed without frequent movement of shelves, balancing storage efficiency and convenience.
