Abstract

Die vorliegende Erfindung betrifft eine mobile Baumaschine, insbesondere einen Bagger, mit einem durch einen Aktor um eine horizontale Drehachse schwenkbaren Baggerschild (50), und einer Zusatzeinrichtung, insbesondere einer Zusatzachse, welche an dem Baggerschild durch Anheben und Absenken des Baggerschildes so ankoppelbar ist, dass das Baggerschild formschlüssig in eine Aufnahme an der Zusatzeinrichtung eingreift. Erfindungsgemäß weist die Zusatzeinrichtung und/oder das Baggerschild eine Führungseinrichtung (10,14) auf, durch welche die Zusatzeinrichtung beim Absenken des Baggerschildes auf einer anderen Kontur am Baggerschild geführt wird als beim Anheben.The present invention relates to a mobile construction machine, in particular an excavator, with an activatable by an actuator about a horizontal axis of rotation excavator shield (50), and an additional device, in particular an additional axis, which is coupled to the excavator shield by raising and lowering the excavator shield so that the excavator blade engages positively in a receptacle on the additional device. According to the invention, the auxiliary device and / or the excavator shield on a guide device (10,14), through which the auxiliary device is guided when lowering the excavator blade on a different contour on the excavator blade than when lifting.
