Description

Baufahrzeug mit höhenverstellbaren Stützen Die Erfindung betrifft ein Daufahrzeu,.. z. 3. Mobilkran oder Bagger mit höhenverstellbaren Stützen zum Erhöhen der Standfestio-keit. Construction vehicle with height-adjustable supports The invention relates to a Daufahrzeu, .. z. 3. Mobile crane or excavator with height-adjustable supports to increase the stability.

Es sind bereits Baufahrzeuge bekannt, an deren Rahmen schwenkbare höhenverstellbare Stützen befestiGt sind. Diese Stützen sind in der Länge begrenzt und erfüllen ihre Aufgabe nur unzureichend. Auch sind Abstützungelil bekannt, bei denen an einem quer zum Fahrzeug angeordneten Träger nach Jeder Seite eine Stütze ausschiebbar ist. Diese Stützen lassen sich nicht weit ausschieben, weil ihr TeleskopausleGer im eingefahrenen Zustand gegen den Teleskopausleger der gegenüberliegenden Stütze stößte. c# ti Eine VergrößerunG der Ausschieblän#-re wurde schon dadurch ID erreicht daß die Teleskopausleger in nebeneinander gela--erten Führuni--en verschiebbar sind. Hierbei können die l#D l#I Teleskopausle,#-er über die gesamte Fahrzeugbreite reichen. LD Diese Anordnun- hat jedoch den Nachteil, daß die Stützen unterschiedlich weit außerhalb der Achsen an-eordnet sind. Nach der Auf--abe der Erfindung sollen die Stützen für ein Baufahrzeu3, z. B. -.--,lobilkran oder Bagger so angeordnet sein, daß sie -tiö#,glichst weit ausziehbar und auf beiden Seiten gleich sind. Diese Aufgabe wird dadurch gelögt$ daß die Stützen an bekannten.. sich über die Baufahrzeugbreite erstreckenden Teleskopauslegern befestigt sind, deren rührungen nebeneinander und parallel zueinander so verschwenkt an dem 3aufahrzeu- befestict sind, daß die Stützen im ausgezogenen Zustand gleich weit außerhalb der cx Achsen des baufahrzeuges liegen.Construction vehicles are already known to whose frames pivotable, height-adjustable supports are attached. These supports are limited in length and do their job inadequately. Support elements are also known in which a support can be pushed out to each side on a carrier arranged transversely to the vehicle. These supports cannot be extended far because their telescopic boom hit the telescopic boom of the opposite support when retracted. c # ti An enlargement of the extension length has already been achieved by the fact that the telescopic arms can be moved in guide rails that are mounted next to one another. The l # D l # I telescopic arms can extend over the entire width of the vehicle. However, this arrangement has the disadvantage that the supports are arranged at different distances outside of the axes. According to the task of the invention, the supports for a construction vehicle, e.g. B. -.--, mobile crane or excavator can be arranged in such a way that they can be extended as far as possible and are the same on both sides. This task is solved by the fact that the supports are attached to known telescopic booms extending over the width of the construction vehicle, the contacts of which are pivoted next to one another and parallel to one another in such a way that the supports in the extended state are equidistant from the cx axes of the construction vehicle.

Die Führungen sind ohne einen besonderen Aufwand verschwenkt an dem Fahrzeugrahmen befestigt. Man erreicht damit aber den Vorteil.. daß die Abstützung symmetrisch und die maximale Belastung entsprechend der Ausladung somit besser zu überwachen ist. Die Teleskopausleger werden zwecImP-ßig von Hand ausgezogen und In den Endstellungen durch Steckbolzen gesichert. Die Stützen können von hand, hydraulisch oder mechanisch in der Höhe verstellt werden. Ein Au8führungsbeispiel der Erfindung ist in der Zeichnung dargestellt und im folgenden näher erläutert. Es zeigen: Fig. 1 das Fahrgestell eines Baufahrzeuges in der Rückansieht., Fig. 2 die Draufsicht von Fig. 12 Fig. 3 die Seitenansicht von Fig. 1. The guides are attached to the vehicle frame in a pivoted manner without any special effort. This has the advantage, however, that the support is symmetrical and the maximum load can therefore be better monitored in accordance with the overhang. The telescopic booms are pulled out by hand for two purposes and secured in the end positions with locking pins. The height of the supports can be adjusted by hand, hydraulically or mechanically. An exemplary embodiment of the invention is shown in the drawing and explained in more detail below. 1 shows the chassis of a construction vehicle from the rear, FIG. 2 shows the top view of FIG. 12, FIG. 3 shows the side view of FIG. 1.

Die Stützen 1 sind in Stützrohren la höhenvers"%-lellbar. Diese sind an den Teleskopauslegern 2 befestigt, die in Führungen 3 seitlich ausfahrbar sind. Es sind zwei Führungen nebeneinander an dem Fahrzeugrahmen 4 befestigt. Aus der Fig. 2 ist ersichtlich, daß die Führungen 3 zur Mittelachse des Fahrzeuges derart verschwenkt sind, daß die Stützen 1 im ausgeschobenen igustand syri-metrisch zur Fahrzeuglängsachse angeordnet sind.The supports 1 are vertically adjustable in support tubes 1 a. These are attached to the telescopic arms 2, which can be extended laterally in guides 3. Two guides are attached to the vehicle frame 4 next to one another. From FIG. 2 it can be seen that the Guides 3 are pivoted to the central axis of the vehicle in such a way that the supports 1 in the extended igustand are arranged Syrimetrically to the longitudinal axis of the vehicle.
