During empty pallet check, floor running boards and floor transverse boards are checked. By this, missing blocks can also be identified. Cover oards are arranged longitudinal or crosswise. The test pressure for the cover and floor boards is variably adjustable. A tension control is also possible by an additional device. Even for loaded pallets, the floor running boards and floor transverse boards including blocks can be checked provided the minimum weight of the load is ensured for the required counter-pressure.
