Meaning
Material handling guidelines outline the technical and environmental requirements for operating industrial trucks in high-bay warehouses. Originating in Germany, the vdma directives establish the flatness and leveling standards required for the safe operation of very narrow aisle forklifts. These guidelines are published by the German Engineering Association and are recognized globally as a standard for warehouse flooring.
They ensure that forklift manufacturers and floor builders work to the same technical specifications.
Floor Specification
The guidelines define the permissible height differences between the forklift wheel tracks to prevent mast oscillation. When contractors build a floor to comply with vdma directives, they must achieve exceptionally tight tolerances along the narrow aisles. This is measured using precise digital instruments that trace the wheel paths.
If the floor is uneven, the truck cannot operate safely at high lifts.
Vehicle Operation
Forklift manufacturers specify that their high-lift trucks must run on floors that meet these standards to maintain stability. If a warehouse floor does not meet the vdma directives, the vehicles are forced to operate at lower speeds, which decreases the efficiency of the facility. This direct relationship between floor quality and vehicle performance is a key factor in warehouse design.
Contractual Compliance
Developers and builders include these guidelines in construction contracts to define the required quality of the floor before handover. A formal survey must verify compliance with vdma directives before the racking is loaded and the trucks are deployed. This prevents disputes between the flooring contractor and the warehouse operator regarding floor quality.
Achieving compliance is essential for the warehouse to run at its planned capacity without operational delays, ensuring that the heavy investments in automation are fully realized.
