Abstract

Verfahren zur Lastminderung mindestens eines in einem Groß-Hydraulikbagger angeordneten Motors, insbesondere eines Verbrennungsmotors, indem in einer drehzahlmäßigen Überlastsituation des jeweiligen Motors mindestens ein hydraulischer Nebenverbraucher, insbesondere eine Arbeitspumpe, in seiner Fördermenge soweit abgesenkt wird, bis der jeweilige Motor wieder in seinen betriebsgemäßen Drehzahlbereich zurückgeführt ist.
