Super flat floor sarere quired where very narrow aisle trucks are employed to place and pick goods stacked to heights over12-13m, where the path of the truck is fixed and the truck is floor supported,i.e.it runs on the floor.
In very narrow-aisle (VNA) warehouses, forklifts travel 6-foot wide aisles between storage racks with the aid of rack-mounted rails or a wire guidance system embedded in the floor. While moving down the aisles, these lift trucks can raise their forks to retrieve or place products at various levels. For these forklifts to perform as intended, defined traffic floors must be extraordinarily flat and level, or super flat. Since the lift truck travels the same route over and over, the smoothness of the wheel paths in super flat aisles becomes extremely important. Although super flat slabs are placed in long, narrow strips approximately 15 feet wide, tolerance only needs to be confirmed in the wheel tracks. Each of the traffic paths should be directly measured, using a continuous-recording floor profilometer configured to run exactly in the wheel tracks.
