When opening the editing window of a vehicle/unit, you will find multiple tabs that have different purposes.

If your vehicle's tracking device receives information about axels, you will see the Weight on axels tab.

The platform doesn't recognize axles by their location. Therefore the name of each axle has to be defined in the section Names of the axles and afterwards assigned to the axles.

The name assigned to the axles provides the possibility to set an alert for Overweight on axles (with time over limits).
