Amazone UX 01 with SwingStop Pro and ContourControl
Acceleration sensors on the boom measure the velocity of boom swing in direction of travel. Hydraulic rams actively counteract this swing. If the nozzle accelerates at a faster rate than the machine, the system will temporarily increase the application rate via quick-response valves. If the acceleration of the nozzle is slower, the system will reduce the application rate. The claimed effect of this an increased accuracy.
