Electrohydraulic control circuit for a large manipulator
An electrohydraulic control circuit includes a hydraulically-operated drive assembly and an emergency valve. The hydraulically-operated drive assembly includes an electrically-actuated proportional valve and hydraulic operating lines. The proportional valve is connected to the hydraulic operating lines for actuation of the drive assembly in a normal operation mode. The proportional valve is also connected to a pressure supply line and to a return line. The emergency valve is connected to the hydraulic operating lines for actuation of the drive assembly in an emergency operation mode. In the emergency operation mode, the emergency valve is actuated via an emergency operating unit.
