1、 Advantage: Core focus on "space utilization" and "batch storage" Higher space utilization: Double depth shelves store 2 rows of goods along the depth direction, reducing the number of channels and increasing storage density by 30% -50% compared to beam shelves. They are suitable for warehouses with limited space or high rent. Lower unit storage cost: With the same warehouse area, more goods can be stored, and the cost of shared land rent and shelf sets is lower, especially suitable for batch storage scenarios. Batch management is more efficient: a single set of shelves can store more goods of the same variety in a centralized manner, reducing inventory dispersion and lowering management costs for small and large quantities of goods (such as household appliances and fast-moving consumer goods). 2、 Disadvantage: Shortcomings concentrate on "efficiency" and "flexibility" The storage and retrieval efficiency is low, and there is a "first in, first out" problem: to retrieve goods from the inner side, they need to be moved to the outer side first, which is not suitable for "first in, first out" scenarios (such as fresh produce and short warranty products). The single operation time is 20% -30% longer than that of beam shelves. High requirements for equipment and personnel: specialized forklifts (such as telescopic forklifts) are needed, resulting in equipment procurement costs that are over 50% higher; Personnel need professional training, otherwise it is easy to bump the shelves. Poor flexibility and unsuitability for multiple types of goods: fixed storage location specifications, high renovation costs; Multiple SKUs and high-frequency turnover goods (such as e-commerce small items) frequently "move out and take in", with much lower efficiency than beam shelves. Difficulty in inventory management: The goods on the inner side are blocked, and inventory needs to move the goods on the outer side, which is about 40% inefficient and prone to discrepancies between accounts and reality. Additional investment in the WMS system is required to make up for this.
