The integrated weighing system on the hydraulic suspension, also known as "overload system", measures the pressure in the hydraulic circuits of the axles and drawbar suspension. As a result, the indicated weight is largely independent of the position of the load in the vehicle. This weighing system is not intended for commercial purposes and is for information purposes only: it cannot be used as a basis to invoice the transported quantity. However, it is very reactive and allows, in particular, to monitor the unloading process of the trailer, authorising some manual or automatic adaptations during this process ("dynamic weighing").
