Description

Baukrane werden an verschiedenen Stellen verwendet, sie müssen daher oft von einer Baustelle zur anderen transportiert werden. Bei Turmbaukranen ist der Transport wegen der großen Höhe besonders schwierig. Ist der Turm umlegbar angeordnet, dann kiinnen bei umgelegtem Turm nur gerade Wege und solche mit geringen Krümmungen befahren werden. I?in fester Turm wird zum Transport des Kranes abgenommen, meist zerlegt und für sich zu der anderen Baustelle gebracht. Dort muß er wieder aufgebaut, auf das Fahrgestell gehoben und mit diesem zusammengebaut werden.Construction cranes are used in different places, so they have to are often transported from one construction site to another. For tower cranes is transport particularly difficult because of the great height. If the tower is arranged so that it can be folded down, then with the tower down, only straight paths and those with slight curves can be found be driven on. I? In fixed tower is removed to transport the crane, mostly dismantled and brought to the other construction site for yourself. There he must be rebuilt lifted onto the chassis and assembled with it.

Die Erfindung ermöglicht, fahrbare umlegbare Turmbaukrane leicht und sicher von einer Baustelle zur anderen zu bringen, ohne daß die vorerwähnten Einschränkungen in Kauf genommen werden müssen. Sie besteht in einem bei umgelegtem Turm senkrechten Gelenk in diesem, das beim Heben des Turmes und in Arbeitsstellung desselben durch Gurtwinkel o. dgl. überbrückt, also steif gemacht ist. Durch eine solche Ausbildung des Turmes können die beiden durch das Gelenk miteinander verbundenen Teile gegeneinander verschwenkt werden, so daß mit dem Kran beim Transport ohne Schwierigkeiten auch enge Kurven, wie Einfahrten in l 1ö fe o. dgl., befahrbar sind. Die in der Arbeitsstellung des Turmes erforderlichen Gurtwinkel können eingebaut werden, ohne daß schwere Teile zu heben sind. Die Herstellung des Gelenkes im Turm ist, da das Gelenk nur gering beansprucht ist, einfach. Sie erfordert daher keinen großen Mehraufwand.The invention enables mobile folding tower cranes easily and to bring safely from one construction site to another without the aforementioned restrictions must be accepted. It consists of a vertical tower when the tower is folded down Joint in this, the same when lifting the tower and in the working position Belt angle or the like bridged, so made stiff. Through such training of the tower, the two parts connected to one another by the joint can be used against one another be pivoted, so that with the crane during transport without any difficulties tight curves, such as entrances to l 1ö fe or the like., are passable. The one in the working position The belt angle required for the tower can be installed without the need for heavy parts are to be lifted. The manufacture of the joint in the tower is because the joint is only slight is claimed, simple. It therefore does not require a great deal of additional effort.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung, dargestellt. Es zeigen Fig. i eine Seitenansicht des Turmbaukranes mit umgelegtem Turm, Fig. 2 eine Draufsicht auf den Turmbaukran beim Befahren einer engen Kurve und Fig.3 eine Seitenansicht des durch Gurtwinkel überbrückten Gelenkes im Turm.An exemplary embodiment of the invention is shown in the drawing. FIG. 1 shows a side view of the tower crane with the tower folded down, FIG. 2 shows a plan view of the tower crane when driving on a tight curve and FIG a side view of the joint in the tower bridged by belt angles.

Der gegebenenfalls als Drehkran ausgebildete fahrbareTurmbaukran besitzt nach denFig. i und 2 das Fahrgestell i, den Turm 2 und den Ausleger 3. Der Turm ist an einer Stütze 4 des Fahrgestells drehbar gelagert, so daß er zum Transport umgelegt und zum Gebrauch wieder aufgerichtet werden kann. Etwas außerhalb der Mitte, nach dem Fahrgestell zu, ist er mit einem im umgelegten Zustand senkrechten Gelenk 5 versehen, das den Turm in zwei gegeneinander verdrehbare Teile aufteilt. In den Fig. i und 2 ist zum Transport des Turmbaukranes der Ausleger 3 an den Turm 2 angeklappt und letzterer umgelegt. An dem hinteren Teil des Turmes ist am Ende ein Stiitz"vagen 6 befestigt, dessen Räder in bekannter Weise mit einer Handlenkung versehen sein können. Wird nun der Turmbaukran von dem Fahrgestell i von einer Baustelle zur andern gefahren, dann kann der hintere Turmteil um das Gelenk 5 schwenken, wenn die Straße enge Krümmungen aufweist oder der Kran, wie in Fig. 2 dargestellt, durch ein Tor oder eine Einfahrt in einen Hof o. dgl. gebracht werden soll. Der an den Turm angeklappte Ausleger 3 bewegt sich hierbei mit dem hinteren Turmteil und kann je nach seiner Länge, auch ohne zu stören, etwas über dasselbe, nach dem Fahrgestell zu, vorstehen. Gegebenenfalls kann auch das vordere Ende des Auslegers an der Stoßstelle 7 abgenommen und vor dem Aufrichten des Turmes wieder angebracht werden.The mobile tower crane, which may be designed as a slewing crane, has according to fig. i and 2 the chassis i, the tower 2 and the boom 3. The tower is rotatably mounted on a support 4 of the chassis so that it can be used for transport can be folded down and erected again for use. A little out of the middle towards the chassis, it is with a vertical joint when folded down 5 provided, which divides the tower into two mutually rotatable parts. In the FIGS. 1 and 2, the boom 3 is folded onto the tower 2 for the transport of the tower crane and the latter turned over. At the back of the tower there is a vague support at the end 6 attached, the wheels of which are provided with manual steering in a known manner can. If the tower crane is now removed from the chassis i from one construction site to another driven, then the rear part of the tower can pivot about the joint 5 when the road has narrow curves or the crane, as shown in Fig. 2, through a gate or an entrance to a courtyard or the like is to be brought. The one that was folded against the tower Boom 3 moves here with the rear tower part and can depending on its Length, even without disturbing, protrude a little over the same, towards the chassis. If necessary, the front end of the boom at the joint 7 can also be removed and reattached before erecting the tower.

Ist der Turmbaukran an der neuen Verwendungsstelle angekommen, dann wird vor dem Aufrichten des Turmes das Gelenk 5 durch Gurtwinkel 8 (Fig. 3) überbrückt, die ihm wieder die für das Arbeiten notwendige Festigkeit geben. Hierbei ist es vorteilhaft, daß die Gurtwinkel bei umgelegtem Turm abgenommen und wieder angebracht werden können.If the tower crane has arrived at the new place of use, then the joint 5 is bridged by belt angle 8 (Fig. 3) before the tower is erected, which give it the strength it needs to work. Here it is It is advantageous that the belt angle is removed and reattached when the tower is folded down can be.
