Using air suspension, one can easily measure the axle pressure.
As the air-bellow pressure is always proportional to the load on the axle, one can measure the bellow pressure with a gage scaled in tonnes. The gage is filled with silicone-oil to withstand vibrations and is positioned, well protected, in the aluminum compartment at the rear of the HAMMAR. Range of measurement is max. 10 tonnes per axle.
