<p>The invention relates to a concrete mixer truck having a rotatably driven mixer drum, particularly a drum provided with interior mixing elements, and a hydraulic system as a drive source for the mixing process. It is intended to enhance the effect of the mixing process by transmitting vibration energy to the mixture materials. To this effect, a vibration generator is included in the hydraulic system in such a manner that pressure pulses generated in the flow of the hydraulic fluid are superimposed on the mixing movement in the form of vibrations. This superposition effect may be achieved with respect to the rotation of the drum and/or with respect to the movements of a separate mixing tool.</p> |
