Determine Safe Aisle Distance

Designing the aisle width for warehouse pallet racks is a crucial aspect of warehouse layout planning. The goal is to ensure efficient and safe movement of forklifts, personnel, and equipment while maximizing the utilization of space. Here's a guideline for appropriately designing the aisle width and the basis for the design:

1. Forklift Type and Turning Radius: The type of forklift being used plays a central role in determining the required aisle width. Different forklifts have varying turning radii, which dictate how much space they need to maneuver. Reach forklifts, three-way forklifts, and counterbalance forklifts are examples of common types with different turning capabilities.

2. Turning Radius Calculation: Calculate the turning radius of the forklift, which is the minimum space required for the forklift to make a 180-degree turn. This includes the overall length of the forklift and its front overhang.

3. Fork Length: Consider the length of the forks when fully extended, as this impacts the space needed for loading and unloading pallets.

4. Safety Clearance: Ensure a safety clearance between the forklift and the pallet rack structure, as well as between the forklift and the goods on the racks. This clearance is essential to prevent collisions and accidents. A common safety clearance value is around 200mm.

5. Overall Aisle Width Calculation: The minimum aisle width (B) can be calculated using the formula: B = Forklift Turning Radius + Front Overhang + Fork Length + Safety Clearance.

6. Factors Affecting Aisle Width: Consider other factors that might impact aisle width, such as the height of the pallets, the width of the pallets, the layout of the warehouse, and any obstructions or structural constraints.

7. Space Efficiency: While ensuring sufficient aisle width for safe maneuvering, aim to optimize space utilization. Avoid overestimating the aisle width, as this can lead to unnecessary wastage of storage space.

8. Flexibility: Plan for flexibility in aisle widths if you expect changes in your inventory or forklift types over time. Some warehouses use adjustable pallet rack systems that can accommodate varying aisle widths.

9. Consult Manufacturer Guidelines: Forklift manufacturers often provide guidelines for the minimum required aisle width based on the specifications of their equipment. These guidelines can be a valuable reference point during design.

10. Testing and Validation: of course, before implementing the final design, consider conducting tests with actual forklifts to ensure that the designed aisle width is practical and effective.

The safe design of the aisle width for warehouse pallet racks hinges on understanding the specific forklift types, their turning radii, safety clearances, and the overall layout of the warehouse. Striking a balance between safety, efficiency, and space utilization is key to achieving an effective warehouse layout.
