Electrohydraulic control circuit
The invention relates to an electrohydraulic control circuit for controlling a hydraulically actuated control element (5.6), by means of which a segment (5.3) of a manipulator, in particular of a large manipulator for self-propelled concrete pumps, can be adjusted in regard to the orientation of said manipulator, characterised by an electrically controlled first valve (2.4), which is connected to hydraulic working lines of the control element (5.6) for the control of the control element, and leakage-free shut-off valves (2.5, 2.6), which are provided in the working lines of the control element (5.6) and are arranged on the control element (5.6) or the segment (5.3) associated with said control element (5.6) and can be blocked for the normal operation of the control element (5.6), the blocking of the shut-off valves (2.5, 2.6) being controlled by an electronic control unit (ECU) that is separate from the first valve (2.4) and from the shut-off valves (2.5, 2.6).
