The Proviso Plus P200M from Wheel Monitor is an electronic control system for lifting auxiliary axles when they’re not needed. It monitors the load and lifts the axle automatically when the vehicle is lightly loaded or empty. Easy computer setup is said to mean it’s quick to install.
It’s designed specifically for trucks with mechanical suspensions. It will control air pressure in the lift-axle suspension to achieve axle-load equalization.
Standard functions include automatic lifting of the self-steer axle when reversing and/or when the truck is empty. Under 60 km/h, while the truck’s loaded, users can lift the axle manually using the four-way flashers. Strain sensors are installed safely inside the frame rails — protected from road debris and weather — to monitor the axle-load weight. This allows the system to work for all mechanical suspensions.
For Ontario buyers, it’s useful to know that all functions are compliant with SPIF 4 regulations.
It comes as a "low-cost" kit with stainless-steel enclosure and pneumatics built in. Users can also buy the module only and supply their own pneumatics and box.
