Der Erfindung liegt die Aufgabe zu Grunde, einen Mobilkran und ein Verfahren zum Abwinkeln einer Hauptauslegerverlängerung relativ zu einem Hauptausleger eines Mobilkrans zu schaffen, mit denen das Abwinkeln der Hauptauslegerverlängerung vereinfacht wird.The invention has for its object to provide a mobile crane and a method for bending a main boom extension relative to a main boom of a mobile crane, with which the bending of the main boom extension is simplified.
Diese Aufgabe wird durch einen Mobilkran mit den Merkmalen des Anspruchs 1 und durch ein Verfahren zum Abwinkeln einer Hauptauslegerverlängerung relativ zu einem Hauptausleger eines Mobilkrans mit den Merkmalen des Anspruchs 6 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen 2 bis 5 angegeben.This object is achieved by a mobile crane with the features of
Erfindungsgemäß wird bei einem Mobilkran mit einem wippbar hieran gelagerten und über einen Wippzylinder aufrichtbaren Hauptausleger und mit einer lösbar an einem Hauptauslegerkopf des Hauptauslegers über obere Bolzen und untere Bolzen verbundenen Hauptauslegerverlängerung, wobei die Hauptauslegerverlängerung ausgehend von einer Grundstellung nach einem Lösen der oberen Bolzen mittels eines Abwinkelantriebs um eine Wippachse relativ zu dem Hauptausleger abwinkelbar ist, der Abwinkelantrieb an einem Fuß der Hauptauslegerverlängerung angreift, wobei ein für eine andere Aufgabe vorgesehener Antrieb des Mobilkrans die Bewegungsenergie für den Abwinkelantrieb liefert, eine Vereinfachung dadurch erreicht, dass der Abwinkelantrieb derart ausgebildet ist, dass ein Teleskopierzylinder über ein Ein- und Ausfahren des Hauptauslegers die Bewegungsenergie für den Abwinkelantrieb liefert. Hierdurch wird erreicht, dass das Abwinkeln nicht über äußere Hilfsmittel oder zusätzliche Hilfszylinder erfolgt, sondern am Mobilkran vorhandene Antriebe verwendet werden, die ohnehin vorhanden sind. Das Abwinkeln erfolgt nicht über zusätzlich vorzusehende Hydraulikzylinder. Das Abwinkeln an sich erfolgt weitestgehend am Boden beziehungsweise der Ablagestellung des Hauptauslegers, so dass es nicht erforderlich ist, weit oberhalb der Oberkante des Mobilkrans zu arbeiten. Die Erfindung erlaubt das Abwinkeln der Hauptauslegerverlängerung bei auf einem ebenen Boden stehendem Mobilkran mit horizontal ausgerichtetem Teleskopausleger. Für den letzten Teil des Aufwippens der Hauptauslegerverlängerung in eine 20°- beziehungsweise 40°-Stellung wird der Wippzylinder des Hauptauslegers zu Hilfe genommen.According to the invention in a mobile crane with a rockable mounted thereto and erectable via a luffing jib main boom and with a detachably connected to a main boom head of the main boom via upper bolts and lower bolts main boom extension, the main boom extension, starting from a normal position after loosening the upper bolt by means of a Abwinkelantriebs about a luffing axis relative to the main boom is angled, the Abwinkelantrieb attacks on a foot of the main boom extension, a provided for another task drive the mobile crane provides the kinetic energy for the Abwinkelantrieb, a simplification achieved in that the Abwinkelantrieb is designed such that a Telescoping cylinder via a retraction and extension of the main boom provides the kinetic energy for the Abwinkelantrieb. This ensures that the bending is not done via external aids or additional auxiliary cylinder, but existing drives are used on the mobile crane, which are present anyway. The bending does not take place via additional hydraulic cylinder to be provided. The bending itself is largely at the bottom or the storage position of the main boom, so that it is not necessary to work well above the top of the mobile crane. The invention allows the bending of the main boom extension with standing on a flat ground mobile crane with horizontally aligned telescopic boom. For the last part of the raising of the main boom extension into a 20 ° or 40 ° position, the luffing cylinder of the main boom is used.

Hierbei ist insbesondere die Wippachse von einer unteren Rollenkopfachse gebildet.It is provided that in particular the Abwinkelantrieb engages on the one hand on the main boom and on the other hand on the main boom extension in the region of the upper flange. In addition, advantageously, the Abwinkelantrieb is designed such that the main boom extension against the gravitational force of the main boom extension to the rocking axis is pivotally raised and lowered. In this case, in particular, the rocking axis is formed by a lower roller head axis.

Die einzelnen Hauptelemente weisen transportfähige Abmessungen auf und werden in den meisten Fällen nicht mit dem Teleskopkran mitgeführt, sondern werden separat transportiert. Wenn es die Achslasten des Teleskopkrans und die Baugröße der Hauptauslegerverlängerung 4 zulassen, kann bei Bedarf die Hauptauslegerverlängerung 4 mitgeführt werden. Diese würde sich dann in einer Transportstellung seitlich neben und parallel zu dem Hauptausleger 1 befinden. Eine Verbindung der einzelnen Hauptelemente aneinander zu der gewünschten Hauptauslegerverlängerung 4 erfolgt über Bolzenverbindungen in entsprechenden Verbolzungsstellen A, B, C und D.
