For warehouse operation and planning teams, the design of operational aisle width is a core factor that affects both storage density and work efficiency. Many traditional aisle planning schemes adopt unified empirical values without combining the actual operation characteristics of the configured forklifts, which often leads to problems such as excessive aisle occupation that wastes storage space, or insufficient width that causes frequent scraping between vehicles, goods and shelves during turning movements. For electric counterbalance forklifts, the actual turning radius, rather than the nominal parameter on product manuals, should be taken as the core basis for aisle width calculation, to make the final scheme more adaptable to real working conditions.

First, it is necessary to clarify the definition of actual turning radius of electric counterbalance forklifts. Unlike the nominal value marked in public product materials, the actual turning radius refers to the horizontal distance from the turning center point to the outermost protruding point of the vehicle body when the vehicle completes a full turn with no load, half load and rated load respectively. This value includes the extra extension of the counterweight part at the rear of the vehicle during turning, as well as the lateral outcrop of the pallet loaded on the forks, which is easily ignored in general parameter query. The actual turning radius of the same model of electric counterbalance forklift may have a small range of fluctuation under different load conditions, so the maximum value measured under all working conditions should be selected as the basic reference data.

In the specific calculation process, besides the measured maximum actual turning radius, several other necessary variables need to be collected to ensure the accuracy of the result. These variables include the maximum outer width of the pallet commonly used in the warehouse, the reserved safety margin for operator operation deviation, and the protruding size of the shelf support members at the bottom of the two sides of the aisle. After adding all the above values together, the reasonable aisle width that matches the actual operation demand can be obtained. It is not recommended to deliberately reduce the reserved safety margin for the pursuit of higher storage density, otherwise the scraping risk in daily operation will rise significantly.

Many warehouse planners have long been using the nominal turning radius provided by forklift suppliers to calculate aisle width, which will lead to a certain deviation between the final design result and the actual demand. The aisle width calculated based on the measured actual turning radius of electric counterbalance forklifts can effectively avoid the above deviation, which can ensure the smooth and safe passage of vehicles in all daily operation scenarios, and will not cause unnecessary waste of storage space due to excessive reserved margin. This calculation method has been verified in a large number of ordinary storage scenarios, and can bring considerable practical value for warehouse operation teams to optimize operational efficiency.
