Grau actuation
Within the Grau Portfolio, we cover all needs of actuators for truck & trailer life. Within the air brake systems of trucks and trailers, actuators play an important role. Actuators are the devices that convert the compressed air force within a truck or trailer into a mechanical force, which activates the brake.
