Device for controlling at least one hydraulic drive unit controls engine-driven hydraulic pump speed depending on state of actuating device or if appropriate control element

摘要

The device has an actuator (15) for a hydraulic control element (7) that interacts with a device (37) for controlling the vehicle engine revolution rate, or the hydraulic control element interacts with controlling device, to control the speed of the hydraulic pump (9) that is driven by the engine (27) depending on the state of the actuating device or if appropriate the control element.
