Description

Bei fahrbaren Turinkranen für Hochbaumontage ist es bekannt, den Turm kippbar anzuordnen, um ihn ztam Transport umlegen zu können. Dabei liegt aber der Drehpunkt wie bei Auslegern, Druckstützen tt. dgl. bei den Druckgurten oder in der Mitte (bei reinen Druckstützen) des Turmes, so daß die Baulänge des Baukranes bei umgelegtem Turin sehr groß wird, was sich beim Wiederaufrichte@n des Turmes und in der Kurvenfahrt beim Transport des Turmbaukranes nachteilig auswirkt.In mobile turin cranes for building construction, it is known to use the tower to be arranged tiltable in order to be able to fold it down during transport. But that's where it lies Pivot point as with booms, pressure supports tt. Like. With the pressure belts or in the Middle (with pure pressure supports) of the tower, so that the overall length of the construction crane at turned Turin is very big, what happens when the tower and has a detrimental effect in cornering when transporting the tower crane.

Nach der Erfindung wird dieser Nachteil dadurch vermieden, daß der Drehpunkt des Turmes so hoch, wie das Durchfahrtsprofil es zuläßt, und in den hinteren Verband (Zuggurte) gelegt ist. Durch diese hoch- und Rückwärtslegung des Turmdrehpunktes wird die Baulänge des in Transportstellung befindlichen Turmbaukranes erheblich verringert, so daß auch Kurven mit kleinerem Radius befahren werden können. `'Weiter wird die Schwerpunktlage zum .<lufrichten günstiger und damit dieses erleichtert. Die bloch- und Rückwärtslegung des Turmdrehpunktes läßt sich mit einfachen Mitteln und ohne Behinderung der maschinellen Einrichtungen des Kranes durchfuhren.According to the invention, this disadvantage is avoided in that the Pivot point of the tower as high as the passage profile allows, and in the rear Bandage (tension straps) is in place. By moving the tower pivot point up and backwards the overall length of the tower crane in the transport position becomes considerable reduced, so that curves with a smaller radius can be negotiated. `` Go on the center of gravity for. The blocking and backward laying of the tower pivot point can be done with simple means and without hindering the crane's machinery.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen Fig. i eine Seitenansicht eines Turmbaukranes mit tief und in den Druckgurten liegendem Drehpunkt des Turmes, Fig. 2 eine Seitenansicht, wobei sich der Baukran in Transportstellung befindet, Fig.3 eine Seitenansicht eines Turmbaukranes mit hoch und rückwärts in den Zuggurten liegendein Drehpunkt des Turmes und Fig. ,4 eine Seitenansicht, wobei sich der Baukran in Transportstellung befindet.An exemplary embodiment of the invention is shown in the drawing. FIG. 1 shows a side view of a tower crane with deep and in the pressure chords lying pivot point of the tower, Fig. 2 is a side view, wherein the crane is in the transport position, Figure 3 is a side view of a tower crane with a pivot point of the tower lying up and backwards in the tension straps and Fig. 4 a side view, with the crane is in the transport position.

Zur Gegenüberstellung der alten und neuen Bauweise ist in den Fig. i und 2 der Turmbaukran bislieriger Ausführung mit tief und in den Druckgurten liegendem Drehpunkt des Turmes in Arbeits-und Fahrstellung und in den Fig. 3 und 4 der in Ausführung gemäß der Erfindung mit hoch und rückwärts in den Zuggurten liegendem Drehpunkt des Turmes in Arbeits- und Fahrstellung dargestellt. In allen Figuren bezeichnet i das Fahrgestell mit den Maschineneinrichtungen 2 des gegebenenfalls als Drehkran ausgebildeten Baukranes. 3 ist der Turm mit dem Ausleger,. und der Hilfsstützes. 6 ist der Stützwagen für den umgelegten Turm. Letzterer ist mit seinen rückwärtigen Zuggurten 7 an einer hohen Stütze 8 der Fahrgestellplattform 9 bei io drehbar gelagert und wird an seinen Druckgurten ii von einer kleinen Stütze 12 der Plattform unterstützt, von der er durch einen Bolzen zum Umlegen gelöst werden kann. Die Höhe der Stütze 8 ist durch die Turmbreite bestimmt und durch das übliche Durchfahrtsprofil begrenzt, durch das der Turmbaukran beim Transport hindurchfahren muß. 13 sind an den Druckgurten angreifende Streben, die am anderen Ende an der Spindelmutter des Antriebs zum Umlegen und Aufrichten des Turmes angelenkt sind. Die Fig. 2 und q zeigen, daß bei in Transportstellung befindlichem Turm die Baulänge des Baukranes sich gegenüber der alten Bauweise um den großen Betrag 14 verringert. Hierdurch wird das Befahren der Kurven wesentlich erleichtert. Da durch den zurückliegenden Drehpunkt des Turmes 3 der Schwerpunkt desselben mehr nach dem Fahrgestell i zu rückt, wird auch das Aufrichten des Turmes einfacher.To compare the old and new construction, Fig. i and 2 of the tower crane of the previous version with deep and lying in the pressure chords The pivot point of the tower in the working and driving position and in FIGS. 3 and 4 of the in Execution according to the invention with high and backward lying in the tension straps The pivot point of the tower is shown in the working and driving position. In all figures i denotes the chassis with the machine equipment 2 of the eventual construction cranes trained as slewing cranes. 3 is the tower with the boom. and the Auxiliary support. 6 is the support car for the folded tower. The latter is with his rear tension straps 7 on a high support 8 of the chassis platform 9 io rotatably mounted and is supported on its pressure belts ii by a small support 12 the platform supported, from which it can be released by a bolt for folding can. The height of the support 8 is determined by the width of the tower and by the usual The passage profile through which the tower crane can drive during transport is limited got to. 13 are engaging struts on the pressure belts at the other end of the Spindle nut of the drive are hinged for tilting and erecting the tower. 2 and q show that when the tower is in the transport position, the overall length of the construction crane is reduced by a large amount 14 compared to the old design. This makes driving around the curves much easier. Since through the past The fulcrum of the tower 3, the center of gravity of the same more towards the chassis i moves, erecting the tower becomes easier.
