The invention relates to an actuation device for at least one fluidically drivable load (), such as a hydraulic actuator, consisting of at least one valve controller (V1) for controlling an alternating movement of each load () and at least one suspension device () which is connected between the valve controller (V1) and each load (), wherein the suspension device () has an additional valve controller (V2), the valve piston () of which can be moved in a corresponding valve housing in a continuously adjustable manner. The invention is characterized in that a storage device () of the suspension device () is connected to the respective load () via a fluid path by means of the additional valve controller (V2) in a suspension position (V2.IV) of the valve piston () of the additional valve controller (V2). The invention additionally relates to a method for actuating the respective load () using such an actuation device.

Actuating apparatus for at least one fluidically drivable load

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 ().
