A simple and portable system for weighing the load of hydraulic supports of cranes, fire engines and other special vehicles, hard rubber auxiliary wheels of trailers and rigid items such as containers and machines.

All HAENNI scales and sensors can be used in a permanent or semi-fixed installation, recommended when the weight checks are performed at a fixed location. Placing the scales on a recess in the pavement eliminates the need of using levelling mats.

With the portable system WL 104 it is possible to pre-select the overloaded vehicles driving up to 20 km/h and when necessary apply the penalties after re-checking the weight in static modus. The dynamic modus allows the checking of a higher number of vehicles, the static offers a higher level of accuracy and can be used for direct enforcement.
