The core advantages of narrow aisle shelves are high space utilization (20% -30% higher than ordinary shelves), adaptability to higher storage heights, and the need for dedicated narrow aisle forklifts for operation. Therefore, they are more suitable for storing goods with "regular specifications, stable batches, and certain storage height requirements". The specific types are as follows: 1. Goods with regular shapes and requiring pallet storage, such as whole pallets of household appliances (same model air conditioners, washing machines), fast-moving consumer goods (whole boxes of beverages, daily chemical products), industrial components (standardized mechanical parts), etc., need to be stacked on pallets with uniform sizes, able to adapt to narrow aisle shelves to fix cargo positions, and avoid difficulties in access due to irregular cargo shapes. 2. Medium batch and medium turnover frequency goods: such as semi-finished products in the manufacturing industry (such as automotive parts semi-finished products), hot selling inventory in e-commerce regional warehouses (with stable daily output of single SKU), etc. These goods do not need to be "stored for a long time" like double depth shelves, nor do they need to be "frequently and sporadically accessed" like ordinary shelves. The "efficient access+high capacity" of narrow aisle shelves can balance storage density and turnover efficiency. 3. Goods that require upward expansion of space, such as building materials (bulk pipes, boards), packaging materials (whole roll cardboard boxes, bubble wrap), etc. These goods have a moderate weight (mostly 1-3 tons/pallet) and can be expanded upwards with the help of narrow aisle shelves that are "suitable for 8-12 meter high warehouses" to avoid wasting vertical warehouse space. 4. For goods with certain requirements for inventory management accuracy, such as electronic components (high-value, requiring precise location management), pharmaceutical intermediates (requiring batch traceability), etc., the layout of narrow aisle shelves is well-organized, and with the precise positioning function of WMS system and narrow aisle forklifts, it can achieve "fast positioning and accurate access" of goods, reduce errors and omissions, and also take into account high storage density.
