Calculating Minimum Aisle Width for Forklifts
Determining the optimal aisle width for your warehouse is a critical decision. You want to avoid sacrificing valuable space with overly wide aisles, but setting your racking and shelving components too close together would be a disaster.
The calculation of the minimum aisle width for forklift travel and operation involves finding a balance. It requires a thorough understanding of your forklift’s specific parameters and the precise physical requirements they need to operate effectively. This process begins with a comprehensive familiarity with your forklift’s characteristics. Here is the key information you need to assess about your forklifts before you can accurately determine the minimum aisle width they can accommodate.
Forklifts are three-dimensional machines, with fixed lengths, widths, and heights. Generally, forklift height doesn’t pose an issue when determining minimum aisle widths. Some forklifts can reach heights of 30 feet or more when their masts are fully extended. However, it’s the forklift’s length and width that serve as limiting factors. The most critical of these measurements is its width, as it represents the absolute minimum aisle size required for the forklift to pass through.
When operating a sit-down counterbalance forklift, you must account for the space it needs to execute a full turn. Most forklifts are designed with tight turning radii, especially the three-wheel models. Even if your forklift can turn within its own footprint, the turning radius will be at least as long as its length. Typically, forklifts are naturally longer than they are wide, largely due to the tine or fork extensions.
Head and load length
Forklift length is determined by two key measurements. The first is the head length, which defines the boundary between the machine’s rear and the front of the mast, where the forks commence. The second measurement is the load length, which encompasses not only how far forward the metal forks extend but also includes the maximum dimensions of the pallets or other loads that the forklift handles.
Right angle stack
This measurement accounts for the minimum space required by your forklift to transition a pallet from the pick or place position to a configuration where both the machine and the load can safely navigate the aisle. The right angle stack adds to the outside dimensions, turning radius, head and load length. Narrow aisle forklift designs efficiently save space through their specific planning and purpose, but allowances must still be considered when calculating the minimum aisle width.
Regardless of how precise your calculations may be for your forklift’s maximum measurements, it’s essential to provide some additional clearance before finalizing your minimum aisle width. This clearance serves as a safety buffer, accounting for potential operator errors and unforeseen situations. Material management experts recommend a rule of thumb for clearance, suggesting at least one foot as a prudent allowance.
Deciding How Wide Your Warehouse Aisles Should Be
Having one foot of clearance might initially seem like a significant amount of extra space, particularly when you’re striving for maximum efficiency in narrow aisle designs. In warehouses with very limited aisle space, that single foot of clearance could transform a five-foot aisle into a six-foot one, resulting in a 20 percent increase in space. This might seem like a substantial and costly sacrifice.
When determining the width of your warehouse aisles, it’s advisable to err on the side of caution. Starting by understanding the limitations of your mobile equipment is crucial before placing your fixed material handling products in their designated positions. It’s far more practical to ensure the safe positioning of your pallet racks, storage units, and shelving than to invest in new material handling equipment to accommodate narrower warehouse aisles.
Reducing your aisle width to the minimum size that still allows your mobile equipment to function makes practical sense and is one of the most effective strategies for optimizing storage space. However, calculating this minimum aisle size can be a complex task. The best approach is to collaborate with a nationwide distributor of storage products and material handling equipment to ensure the most efficient and space-effective solution for your warehouse.
How Do I Calculate Minimum Aisle Width?
Determining the minimum aisle width for your forklift involves a relatively straightforward calculation:
- Start with your forklift’s Basic Right Angle Stacking Width, sometimes known as the Right Angle Stack.
- Add the length of your load.
- Include an extra 12 inches for clearance.
Formula for Calculating Minimum Aisle Width for Forklifts
Basic Right Angle Stacking Width + Load Length + 12 Inches = Your Minimum Forklift Aisle Width
The resulting total length represents the minimum width required for safe maneuvering by operators with pallet loads. It’s essential to base your calculations on the largest pallet load length to ensure versatility within your warehouse. When dealing with new or irregular pallet loads, it’s advisable to recalculate this figure to ensure safety. Additionally, when considering new forklifts for your fleet, always check the minimum aisle width to confirm their compatibility with your workspace.
Forklift Aisle Width Calculation Example:
Imagine you’re in the process of purchasing a forklift for your warehouse, and you want to ensure that you can navigate your aisles comfortably with a standard pallet. As per the forklift specifications, the model you’re contemplating has a Basic Right Angle Stack measurement of 86 inches.
So, you have: 86 inches (Basic Right Angle Stacking Width) + 48 inches (Load Length) + 12 inches (Clearance) = 146 inches Minimum Aisle Width.
However, it’s important to emphasize that this calculation serves as a starting point for your evaluation. Always ensure that your forklift dealer verifies these results before finalizing your purchase decision!
