Bei bekannten fahrbaren Arbeitsgeräten mit einer Aufzugsvorrichtung ist zur Verbindung einer für den Transport erforderlichen Zugdeichsel mit einer im Bereich der Räder vorgesehenen Bremsvorrichtung eine entsprechende Hydraulikleitung vorgesehen. Diese Leitung muß im Bereich der Auslegeelemente und des Fahrgestells in entsprechenden Schlaufen gelegt werden, so daß nur damit eine entsprechende horizontale und/oder seitliche Verschwenkung der Aufzugsvorrichtung bzw. der Auslegeelemente möglich ist. Der Schwenkbereich der Aufzugsvorrichtung in Arbeitsstellung wird durch diese Hydraulikleitungen eingeschränkt und eine Drehbewegung der Auslegeelemente ohne entsprechende Rückschwenkung ist nicht möglich ( DE 198 09 332 C2 ). Gemäß DE 296 16 114 U1 ist eine zum Straßentransport auf einen Anhänger aufsetzbare Hubarbeitsmaschine vorgesehen, deren Fahrgestell einen Lagerbock mit vorstehendem Endstück aufweist. Damit ist ein zweites längsverschiebbar gehaltenes Endstück auf dem Anhänger zu betätigen, so daß beim Aufsetzen der Hubarbeitsmaschine auf den Anhänger dessen Bremszug im Bereich einer Tandemachse einfacher wieder in seine Funktionslage gelangt. Gemäß DE 41 31 160 A1 ist eine Schnellkupplung für zwei Bremsseile vorgesehen, die endseitig als axialverschiebliche Baugruppen einen Außenkörper bzw. einen Innenkörper tragen und bei einer Bremsseilzugbefestigung gemäß DE 43 41 674 A1 sind als Kopplungselemente jeweilige Einhängeelemente sowie Einhängeabschnitte an den Seilzugenden vorgesehen.In known mobile working devices with an elevator device, a corresponding hydraulic line is provided for connecting a drawbar required for transport with a braking device provided in the region of the wheels. This line must be placed in the loops and in the region of the Auslegeelemente the chassis, so that only so that a corresponding horizontal and / or lateral pivoting of the elevator device or the Auslegeelemente is possible. The pivoting range of the elevator device in working position is limited by these hydraulic lines and a rotational movement of the Auslegeelemente without corresponding Rückschwenkung is not possible ( DE 198 09 332 C2 ). According to DE 296 16 114 U1 is provided for road transport on a trailer attachable lifting machine, the chassis has a bearing block with protruding end piece. This is a second longitudinally slidably held tail on the trailer to operate, so that when the Hubarbeitsmaschine put on the trailer whose brake cable in the area of a tandem axle easier returns to its functional position.

In this pivot position, a respective position of use can be continuously defined, in which the Auslegeelemente 3 are telescoped by means not described in detail.

Die Auslegeelemente 3 sind dabei im Bereich des Drehkreuzes 5 um die von diesem gebildete vertikale Hochachse A schwenkbar abgestützt. An einem unteren, als Basisteil vorgesehenen Auslegeelemente 3' ist dabei vorderseitig eine Zugdeichsel 7 festgelegt, von der ausgehend ein Bremsgestänge 8 zu zumindest einem der am Fahrgestell F vorgesehenen Räder 9 geführt ist. Dieses Bremsgestänge 8 ist dabei mit einer Bremsvorrichtung B (Fig. 2) verbunden, so daß eine nach Art einer Auflaufbremse wirksame Baueinheit gebildet ist.The extension elements 3 are supported pivotably in the region of the turnstile 5 about the vertical vertical axis A formed by this.
