The electric forklift  is a warehousing logistics equipment suitable for warehouse operation. When building a warehouse or factory, or placing a new shelf in a warehouse or factory, a passage with appropriate width shall be reserved to avoid affecting the turning, stacking, loading and unloading of an electric forklift, and affecting the work efficiency. If it is not calculated in advance, subsequent adjustment will take time and effort. So, how wide passage should be reserved to make full use of the working space? The electric forklift manufacturer  will give you a detailed explanation. To calculate the reserved width of the passage that can make the electric forklift  work normally, we need to know a formula: right-angle stacking passage width=the minimum turning radius of the forklift+the front overhang of the forklift+the length of the forklift fork/pallet+the safety distance. The safety distance is generally 200 mm. The front overhang of the forklift refers...
