摘要：
A concrete transit mixer truck includes a control system that automatically controls rotation of the mixer drum at a constant drum speed when the mixer truck is traveling. When sensed speed of the truck exceeds a threshold, the control system automatically causes a hydraulic system to rotate the drum at a constant speed, regardless of the truck engine speed.
