Description
Turmdrehkran Der begrüßenswerte große Einsatz von Turmdrehkranen bei der Errichtung von Wohnhäusern usw. ist zum Teil darauf zurückzuführen, daß die Krane von einer Baustelle zur anderen in unzerlegtem Zustand auf der Straße transportiert und nach Ankunft auf der Baustelle sofort montiert werden können. Durch die ständig zunehmende Höhe der Turmdrehkrane wird aber auch die Transportlänge über das zulässige Maß der Straßenverkehrsordnung vergrößert, was Schwierigkeiten beim Krantransport verusracht.Tower crane The welcome large use of tower cranes at the construction of houses, etc. is partly due to the fact that the Cranes transported by road from one construction site to another without being dismantled and can be installed immediately upon arrival at the construction site. By constantly however, the increasing height of the tower cranes also means that the transport length exceeds the permissible limit The degree of traffic regulations increased, causing difficulties in crane transport verusracht.
Es entstehen insbesondere bei den größeren Krantypen Schwierigkeiten, da die Gesamtzuglänge auf Grund der Straßenverkehrsordnung das zulässige Maß von 25 Metern nicht überschreiten darf.Difficulties arise, especially with the larger crane types, because the total train length due to the road traffic regulations is the permissible dimension of Must not exceed 25 meters.
Es ist bereits vorgeschlagen worden, die Kranhauptsäule teleskopartig auszuführen, um innerhalb der zulässigen Zuglänge zu bleiben. Eine derartige Ausführung erfordert jedoch aufwendige konstruktive Maßnahmen und begrenzt darüber hinaus die Höhe der Kransäule.It has already been proposed to make the crane main column telescopic to stay within the allowable train length. Such a design However, it requires complex structural measures and also limits the Height of the crane column.
Diese Mängel werden teilweise durch einen bekannten Kran behoben, der dadurch auf einem Fahrzeug angeordnet werden kann, daß die Kransäule in Höhe der Schwenkachse des Auslegers geteilt ist und dessen Spitze um eine feststehende Schwenkachse umgeklappt werden kann. Bei diesem bekannten Kran wird jedoch die gesamte Kranspitze nach einer Seite hin umgeklappt. Dadurch tritt eine ungünstige einseitige Verbreiterung des Transportzuges auf, und das Fahrzeug wird darüber hinaus asymmetrisch belastet.These deficiencies are partially remedied by a known crane, which can be arranged on a vehicle that the crane column in height the pivot axis of the boom is divided and its tip around a fixed one Swivel axis can be folded. In this known crane, however, the entire Crane tip folded down to one side. This results in an unfavorable one-sided Widening of the transport train, and the vehicle also becomes asymmetrical burdened.
Es wurde nun gefunden, daß diese Nachteile vermieden werden können, wenn man die Turmspitze des Krans in zwei Teile teilbar ausführt. Gegenstand der Erfindung ist demnach ein Turmdrehkran mit geteilter Kransäule und seitlich verschwenkbarer und am Turm verriegelbarer Turmspitze mit dem Kennzeichen, daß die Turmspitze in zwei Teile teilbar ausgebildet und jeder dieser Teile so angeordnet ist, daß er um ein Drehgelenk mittels einer Schwenkung um 180° seitlich an den Kranturm herangeklappt werden kann.It has now been found that these disadvantages can be avoided if you make the tower top of the crane divisible into two parts. Subject of The invention is therefore a tower crane with a split crane column and laterally pivotable and the spire that can be locked on the tower with the indication that the spire is in formed two parts divisible and each of these parts is arranged so that it Folded to the side of the crane tower around a swivel joint by means of a swiveling 180 ° can be.
Vorzugsweise erfolgt diese Verschwenkung der Turmspitze zusammen mit dem Seil, ohne daß dieses abgenommen zu werden braucht.This pivoting of the spire is preferably carried out together with the rope without having to be removed.
Die Erfindung bietet nicht nur den Vorteil, daß ein unzerlegter Transport des Turmdrehkrans ohne Überschreitung der zulässigen Länge möglich ist, sondern gestattet weiterhin diese seitliche Verschwendung der Turmspitze, ohne daß dabei eine einseitige Verbreiterung des zusammengelegten Kranturms auftritt. Damit wird auch eine einseitige Belastung des Transportfahrzeuges vermieden.The invention not only offers the advantage that a transport without dismantling of the tower crane is possible without exceeding the permissible length, but still allows this lateral waste of the spire without doing so a one-sided widening of the collapsed crane tower occurs. So that will one-sided loading of the transport vehicle is also avoided.
Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt. Es zeigt A b b. 1 den Turmdrehkran ohne verschwenkter Spitze, also in voller Länge auf Transportfahrzeugen montiert, A b b. 2 den Turmdrehkran mit seitlich herumgeklappter Spitze, also in verkürzter Länge, auf Transportmitteln aufgeladen und A b b. 3 eine Draufsicht auf den Vorderteil des Turmdrehkrans mit seitlich herumgeklappter Spitze nach A b b. 2.The invention is shown in the drawing in an exemplary embodiment. It shows A b b. 1 the tower crane without the tip pivoted, i.e. in full length mounted on transport vehicles, A b b. 2 the tower crane with the Pointed, so in a shortened length, loaded on means of transport and A b b. 3 a Top view of the front part of the tower crane with the tip folded sideways according to A b b. 2.
Die bisher in geschlossener Schweißkonstruktion ausgeführten Turmdrehkran-Konstruktionen sind an der Spitze geteilt, derart, daß diese Spitze 1 durch Lösen einiger Schrauben in zwei Teile getrennt werden kann. Jeder Teil der Spitze kann dann um Drehgelenke 3 seitlich an den Kranturm 2 herangeklappt werden, derart, daß die einzelnen Hälften der Kranspitze eine Schwenkung um 180° ausführen. Dies bedeutet den Vorteil, daß die geteilte Turmspitze, ohne daß eine Demontage notwendig ist, rechts und links über Gelenke 3 an die Turmkonstruktion 2 heranschwenkbar ist und mit dem Turm verriegelt werden kann. Diese Verschwenkung der Turmspitze ermöglicht eine einfache Verkürzung der gesamten Länge des Turmdrehkrans, also des Zuges, ohne erheblichen Kostenaufwand. Bisher war er erforderlich, die Turmspitze vom eigentlichen Turm zu demontieren, wozu ein Autokran eingesetzt werden rnußte, welcher durch das Heranbringen an die Baustelle sehr hohe Kosten verursachte. Diese behelfsmäßigen Mittel sind dank der vorliegenden Erfindung nunmehr überflüssig.The tower crane constructions, which were previously executed in a closed welded construction are divided at the top, so that this tip 1 by loosening a few screws can be separated into two parts. Each part of the tip can then be pivoted around 3 can be folded up to the side of the crane tower 2 in such a way that the individual halves Swing the crane tip by 180 °. This has the advantage that the split spire, without the need to dismantle, right and left can be pivoted to the tower structure 2 via joints 3 and locked to the tower can be. This pivoting of the spire enables a simple shortening the entire length of the tower crane, i.e. the train, without significant expense. So far it was necessary to dismantle the spire from the actual tower, for which a truck crane had to be used, which by bringing it up to the Construction site caused very high costs. These makeshift funds are thanks to the The present invention is now superfluous.
