Abstract

Die Erfindung betrifft ein Verfahren zur Drehzahlnachführung eines hydraulischen Kranantriebs mit wenigstens einem hydraulischen Verbraucher (7, 11), der über wenigstens eine hydraulische Verstellpumpe (3) mit einem einstellbaren Volumenstrom gespeist wird, wobei wenigstens eine der Verstellpumpen durch das Antriebsaggregat (1) des Krans angetrieben wird, und wobei die Drehzahl des Antriebsaggregats und der Schwenkwinkel der wenigstens einen Verstellpumpe in Abhängigkeit des angeforderten Volumenstroms für wenigstens einen Verbraucher und/oder aufgrund eines weiteren Parameters durch die Kransteuerung gesteuert und/oder geregelt werden.
