57	Abstract	AB	Elektrohydraulischer Steuerkreis (1) zum Ansteuern eines hydraulisch betätigten Antriebsaggregates (2), mittels dessen ein Mastsegment eines Manipulators, insbesondere eines Großmanipulators für Autobetonpumpen, hinsichtlich seiner Orientierung verstellbar ist, mit einem elektrisch angesteuerten Proportionalventil (3), welches mit hydraulischen Arbeitsleitungen (4, 5) des Antriebsaggregates (2) zu dessen Ansteuerung verbunden ist. Aufgabe der Erfindung ist, einen elektrohydraulischen Steuerkreis anzugeben bzw. einen Manipulator zu schaffen, der eine einfache Steuerung und ein hervorragendes Ansprechverhalten der Antriebe bzw. Mastsegmente ermöglicht. Diese Aufgabe löst die Erfindung dadurch, dass das Proportionalventil (3) mit einem Schrittmotor (6) ansteuerbar ist. Außerdem betrifft die Erfindung einen Manipulator, insbesondere einen Großmanipulator für Autobetonpumpen.
