Meaning
Industrial flooring standards define the permissible surface deviations and flatness criteria for narrow-aisle warehouses. In these highly structured environments, din 15185 regulates the flatness of concrete floors in aisles used by very narrow aisle forklifts. This standard ensures that high-lift trucks can operate safely at maximum speed and height without risk of collision with racking systems.
It provides specific thresholds for surface elevations along the wheel tracks of the warehouse vehicles.
Tolerance Specification
Safe operation of tall industrial trucks requires extremely tight floor tolerances to prevent the mast from swaying. Under din 15185, floor leveling is evaluated by measuring the height difference between two parallel truck tracks. This difference determines the risk of truck tilting, which increases proportionally with the lift height.
Elevated floors that meet these tight specifications reduce the mechanical wear on industrial vehicles.
Vehicle Guidance
Forklifts operating in high-bay aisles rely on guidance systems that are sensitive to floor unevenness. When a floor does not comply with din 15185, the mast sways, causing the vehicle control system to automatically slow down or stop to prevent accidents. This deceleration decreases overall warehouse productivity.
Thus, the standard facilitates the smooth operation of both wire-guided and rail-guided machinery.
Compliance Validation
Engineers verify floor flatness using specialized measuring instruments that run along the specific paths of the truck wheels. Measurements of din 15185 compliance must occur before racking installation begins to allow for correction of any identified high or low points. Surface grinding resolves out of tolerance zones by smoothing the concrete to meet the required thresholds.
A formal survey report certifies that the aisle is ready for high-speed automated traffic, providing a baseline document that protects both the flooring contractor and the warehouse operator from future liability.
