Well, maybe not.
For most material handling applications and warehouses, your floor is flat and level enough. What if you are using pallet rack that is 24’ high or even 30’ plus? The answers are that it depends upon a few factors such as overall height of your system, type of forklift, and width of your aisle. For example, in a conventional rack system with 12’ aisles and 20’ pallet rack height, the operator would likely not notice a “bump” in the floor causing it to lean. Now, take a very narrow aisle pallet rack system. The aisles are about 60” wide and typically store material 30’ high or so. A floor that is not within tolerance for this application can cause the lift to contact the rack, make forklift loading and unloading difficult, or cause premature failure of equipment.
Floor flatness used to be measured by 1/8” in 10’ increments. It was proved that this was not a completely accurate way of measuring and specifying a floor. This method has now been replaced with an F-number. For a technical explanation of the F-number, please go to this website for more information: http://www.faceco.com/40q.html. It will also explain how to handle VNA rack systems.
In summary, it is always worthwhile to ask the building owner about the floor before you start your material handling or warehouse project
