What is the difference between narrow aisle shelves and drive in shelves 1. Storage logic and density: Narrow aisle shelves need to reserve 1.6-2.2 meters of aisle space for dedicated forklift operations, with moderate storage density (20% -30% higher than ordinary shelves); Drive in shelves do not have independent channels, and forklifts directly enter the interior of the shelves for storage and retrieval, resulting in higher storage density (more than 50% higher than ordinary shelves) and closer to "intensive storage". 2. Access efficiency and flexibility: Narrow aisle shelves can independently access goods from any location, adapt to high-frequency turnover and multiple types of goods, and support "first in, first out" (equipment required); Drive in shelving is a "first in, last out" system, where the inner goods need to be moved to the outer goods. It is only suitable for a small variety and low turnover goods, and has poor flexibility. 3. Equipment and operation requirements: Narrow aisle shelves rely on narrow aisle forklifts (such as three-way stacker trucks), which require high operational accuracy; Ordinary balance weight forklifts can be used for drive in shelves, but attention should be paid to the safety of driving inside the shelves, and higher proficiency is required for operators. 4. Applicable scenarios: Narrow aisle shelves are suitable for medium batch, medium turnover, density and efficiency scenarios (such as e-commerce regional warehouses and manufacturing semi-finished product warehouses); Drive in shelves are suitable for scenarios with large quantities, low turnover, and pursuit of ultimate storage density (such as seasonal stocking and unsold inventory).
