The placement of warehouse racking significantly impacts space utilization.
When planning the layout, we need to consider not only aisle widths but also management and storage methods, such as whether first-in, first-out (FIFO) is used and whether forklifts are used for access.
Therefore, aisle widths between racks are not fixed and need to be adjusted flexibly based on actual conditions and specific needs.
Warehouse shelf aisle width design
1.For manual storage and retrieval of goods, the aisle width is usually set within the range of 1000mm to 1200mm; for forklift storage and retrieval operations, the aisle width needs to be determined according to the type of forklift. Usually, at least 2 meters of space is required, with 2.5m or 3m being the most common. Even for large forklifts, a 4-5 meter aisle may need to be reserved.
2.Depending on the management approach, we can further optimize the number of aisles between racks.
For example, double-depth racking can reduce the number of aisles by half compared to standard heavy-duty shelves; while very narrow aisle Narrow Aisle Racking, with aisles just over one meter wide, significantly saves space. Drive-in racking, a whole-building design, has even fewer aisles.
However, it should be noted that drive-in racking may not achieve 100% picking efficiency, making it unsuitable for warehouses that require batch first-in, first-out operations.
Warehouse rack aisle width solution
1.In the case of fully manual handling, the distance between storage locations should be greater than the width of the largest packaging box used in the storage location, and an additional 20cm should be added to ensure safe and smooth operations.
2.If palletized goods are stored at the bottom of the storage space and the upper level still needs to be moved manually, the distance between storage spaces should take into account the rotatable diameter of the "manual forklift + pallet" and add a safety distance of 20 cm.
3.When using an electric forklift for transportation, the distance between storage locations needs to take into account the slewing diameter of the "electric forklift + upper pallet", plus the safety distance required for turning around, to ensure that the forklift can operate smoothly.
