Abstract

Es wird eine Arbeitsmaschine, insbesondere ein Minibagger, angegeben mit einem ersten Funktionselement (F1), das von einem hydraulischen Motor (2) betätigbar ist, und einem zweiten Funktionselement (F2), wobei der hydraulische Motor (2) eine Bremse (4) aufweist, die in Bremsrichtung von einer Bremskraft (5) und in Löserichtung von einem hydraulischen Druck beaufschlagt ist, der auf einen ersten Wert, bei dem die Bremse (4) mit maximalem Bremsmoment wirkt, und auf einen zweiten Wert einstellbar ist, bei dem er die Bremskraft überwindet. Man möchte einen Betriebszustand der Arbeitsmaschine auf einfache Weise an einen Bediener signalisieren können. Hierzu ist vorgesehen, daß der Druck durch eine Einstelleinrichtung (27) zusätzlich auf mindestens einen dritten Wert zwischen dem ersten Wert und dem zweiten Wert einstellbar ist, bei dem die Bremse (4) mit einem gegenüber dem maximalen Bremsmoment verminderten Bremsmoment auf den Motor (2) wirkt.
