A regulation system for controlling the orientation of a segment () of a manipulator, in particular of a large manipulator for truck-mounted concrete pumps, wherein the segment () is connected to a base () or a preceding segment () of the manipulator via a joint () and can be pivoted at the joint () relative to the base () or the preceding segment () about at least one axis of rotation by means of at least one actuating member (), preferably a hydraulic actuating element, characterized in that the regulation system at least comprises: 

Control system and method for controlling the orientation of a segment of a manipulator

An electrohydraulic control circuit for driving a hydraulically actuated actuating element (), by means of which a segment () of a manipulator, in particular of a large manipulator for truck-mounted concrete pumps, can be adjusted in terms of its orientation, wherein there are provided an electrically driven first valve (), which is connected to hydraulic working lines of the actuating element () for the drive thereof, and leak-free check valves () provided in the working lines of the actuating element (), which valves are arranged on the actuating element () or on the segment () associated with this actuating element () and can be released for the normal operation of the actuating element (), wherein the release of the check valves () is driven by an electronic control unit (ECU) separate from the first valve () and the check valves ().
