Description

Die Erfindung bezieht sich auf die Gegengewichtsanordnung von Autokranen für schwere Lasten, vorzugsweise bei solchen, bei denen der Ausleger in der Transportstellung in Fahrtrichtung zeigt.The invention relates to the counterweight assembly of truck cranes for heavy loads, preferably for those with the boom in the transport position points in the direction of travel.

Bei den bisherigen Autokranen beeinflußte das hinterliegende Gegengewicht den Achsdruck derartig, daß. die- Lenkeigenschaften des Autokranes durch weitgehende Entlastung der- Vorderräder in ungünstigster Weise beeinflußt wurden. _ . Es sind auch schon abnehmbare Gegengewichte bei verfahrbaren Kranen bekannt. Dazu mußte jedoch das in Arbeitsstellung an dem -drehbaren Teil des Kranes angehängte Gegengewicht mittels besonderer Vorrichtungen für die Transportstellung herabgelassen werden. Das zeitraubende Abnehmen des Gegengewichtes, welches teilweise auch mit Hilfe des Kranwindwerkes erfolgte, soll durch die Erfindung vermieden werden. Auch wird ein besonderes Fahrgestell für den Transport des Gegengewichtes überflüssig. Erfindungsgemäß ist das Gegengewicht nun um die gleiche vertikale Achse wie der drehbare Teil des Kranes schwenkbar, jedoch unabhängig von diesem angebracht, so daß es entweder mit dem Kran drehen oder auch unter diesem stehenbleiben kann. Das Gegengewicht wird also weder beim Einhängen noch beim Abnehmen in vertikaler Richtung bewegt.The counterweight behind had an influence on the previous mobile cranes the axle pressure such that. the steering properties of the truck crane through extensive Relief of the front wheels were affected in the most unfavorable way. _. There are also known detachable counterweights in mobile cranes. I had to but the counterweight attached to the rotating part of the crane in the working position be lowered by means of special devices for the transport position. The time-consuming removal of the counterweight, which is partly done with the help of the Crane winch took place, should be avoided by the invention. Also becomes a special chassis for transporting the counterweight is unnecessary. According to the invention the counterweight is now around the same vertical axis as the rotatable part of the Crane can be swiveled, but attached independently of this, so that it can either be the crane can turn or stop under it. The counterweight will so neither when hanging nor when removing in the vertical direction.

Zweckmäßig wird eine Feststellvorrichtung für das Gegengewicht vorgesehen, durch die dieses in der für den gleichmäßigen Achsdruck günstigsten Stellung fixiert werden kann, wenn der Kran verfahren soll.A locking device for the counterweight is expediently provided, by which this is fixed in the most favorable position for uniform axle pressure when the crane is to move.

Eine erfindungsgemäße Ausführungsform zeigt die Abbildung als Seitenansicht des Kranes in Arbeitsstellung.An embodiment of the invention shows the figure as a side view of the crane in working position.

Auf dem Unterwagen i sitzt der drehbare Oberteil 2 mit dem Ausleger 3. Unabhängig vom Oberwagen, jedoch um die gleiche vertikale Achse schwenkbar, ist das Gegengewicht q. angebracht. Beim Arbeiten mit schweren Lasten wird das Gegengewicht durch' die Vörrichtung 5 oder eine ähnliche Fixierung mit dem drehbaren Teil des Kranes verbunden und schwenkt dann gemeinsam mit diesem. Beim Heben leichter Lasten, bei denen ein Gegengewicht nicht erforderlich ist, kann dieses in seiner Transportstellung, . das ist die in der Abbildung gezeichnete Stellung; verbleiben. Söll der Kran aus der Arbeitsstellung mit schweren Lasten in die Transportstellung gebracht werden, so wird der Kran in die in der Abbildung gezeichnete Stellung geschwenkt, die Vorrichtung 5 gelöst und das Gegengewicht nunmehr am Unterwagen fixiert und der drehbare Oberteile in die Fahrtrichtung gedreht. Diese Operation kann ohne zusätzliche Bedienungsleute allein durch den Kranführer in wenigen Sekunden ausgeführt werden. Die Verriegelung oder Entriegelung des Gegengewichtes am Oberwagen :2 oder Unterwagen i kann vom Kranführersitz aus erfolgen.The rotatable upper part 2 with the boom sits on the undercarriage i 3. Independent of the superstructure, but pivotable about the same vertical axis the counterweight q. appropriate. When working with heavy loads, the counterweight becomes by 'the device 5 or a similar fixation with the rotatable part of the Crane connected and then swivels together with it. When lifting light loads, where a counterweight is not required, it can be in its transport position, . this is the position shown in the figure; remain. Should the crane be off from the working position are brought into the transport position with heavy loads, so the crane is swiveled into the position shown in the figure, the device 5 solved and the counterweight is now fixed on the undercarriage and the rotatable upper parts turned in the direction of travel. This operation can be performed without additional operators can be carried out in a few seconds by the crane operator alone. The lock or unlocking the counterweight on the upper carriage: 2 or undercarriage i can from From the crane operator's seat.

Durch diese Gegengewi,chtsanordnung wird einmal ein gleichmäßiger Achsdruck erreicht und außerdem wird ein Arbeiten ohne Gegengewicht ermöglicht, falls nur kleine Lasten zu bewältigen sind.This counterweight arrangement makes for a more even one Axial pressure is reached and it is also possible to work without a counterweight, if only small loads have to be handled.
