Abstract: A regulation system for controlling the orientation of a segment (5.3) of a manipulator, in particular of a large manipulator for truck-mounted concrete pumps, wherein the segment (5.3) is connected to a base (5.4) or a preceding segment (5.3) of the manipulator via a joint (5.5) and can be pivoted at the joint (5.5) relative to the base (5.4) or the preceding segment (5.3) about at least one axis of rotation by means of at least one actuating member (5.6), preferably a hydraulic actuating element,characterized in that the regulation system at least comprises: a first sensor (4.1), which is arranged on a segment (5.3) attached to the joint (5.5) and delivers a first measurement signal—referred to as a “deformation signal”—corresponding to a deformation of the segment (5.3), a second sensor (4.2, 4.3), which delivers a second measurement signal—referred to as an “orientation signal”—corresponding to the spatial orientation of the segment (5.3) attached to the joint (5.5), and at least one actuating element (5.6) associated with the joint (5.5); and is designed to process the deformation signal and the orientation signal as input variables and to determine from these, under consideration of a target orientation of the segment (5.3) associated with the joint (5.5), an actuating signal, which is fed to the associated actuating element (5.6).

Abstract: An electrohydraulic control circuit for driving a hydraulically actuated actuating element (5, 6), by means of which a segment (5.3) 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 (2.4), which is connected to hydraulic working lines of the actuating element (5.6) for the drive thereof, and leak-free check valves (2.5, 2.6) provided in the working lines of the actuating element (5.6), which valves are arranged on the actuating element (5.6) or on the segment (5.3) associated with this actuating element (5.6) and can be released for the normal operation of the actuating element (5.6), wherein the release of the check valves (2.5, 2.6) is driven by an electronic control unit (ECU) separate from the first valve (2.4) and the check valves (2.5, 2.6).
