| Zusammenfassung: | A self-propelled crushing machine comprises a crushing device ; a hydraulic drive system including a crushing device hydraulic motor for driving the crushing device , a first hydraulic pump for driving the crushing device hydraulic motor , and an engine for driving the first hydraulic pump ; a pressure sensor for detecting a load condition of the crushing device ; and a controller ″ for executing control to increase a revolution speed of the engine in accordance with a detected signal from the pressure sensor . Accordingly, even when a heavy load is imposed on the crushing device, a reduction of crushing efficiency can be prevented. |
