Description

Verfahren zur Montage eines Turmkranes Method for assembling a tower crane
Die Erfindung betrifft ein Verfahren zur Montage eines spitzenlosen Turmkranes (insbesondere Turmdrehkranes) und einen spitzenlosen Turmkran, der gemäß dem erfindungsgemäßen Verfahren montierbar ist, aufweisend: ein Turmkranunterteil mit einem Spitzenunterteil; ein Hubauslegersystem aufweisend: einen Hubausleger, ein am Hubausleger montiertes Hubwerk, ein am Hubausleger montiertes Katzfahrwerk, ein am Hubausleger eingeschertes Hubseil, ein am Hubausleger eingeschertes Katzfahrseil; und einen Gegenausleger.The invention relates to a method for mounting a centerless tower crane (in particular tower crane) and a towerless tower crane, which can be mounted according to the method of the invention, comprising: a tower crane base with a point base; a jib system comprising: a jib, a lifting boom mounted on the lifting jib, a trolley mounted on the jib, a hauled on the jib hoist rope, a sheared on the lifting boom Katzfahrseil; and a counter-jib.
Die Montage eines Turmkrans erfolgt bisher so, dass das Kranunterteil mit Spitzenunterteil und Turmspitze montiert wird und anschließend daran zuerst der Gegenausleger mit Hubwerk und dann der Hubausleger mit Katzfahrwerk montiert werden. Anschließend wird das am Gegenausleger befindliche Hubwerk eingeschert. Die Einscherarbeiten machen es erforderlich, dass zum Einscheren ein Montagearbeiter zur Spitze des Hubauslegers gelangt, um dort die Einscherung vorzunehmen. Dieses Verbringen und das anschließende Einscheren in durchaus luftigen Höhen sind zeitaufwendig und für den ausführenden Montagearbeiter mit nicht unerheblichen Risiken verbunden.The installation of a tower crane is done so far, that the crane base is mounted with tip base and spire and then first the counter-jib with hoist and then the lifting boom with trolley are mounted. Subsequently, the hoisting gear located on the counter-boom is sheared. The Einscherarbeiten make it necessary that for shearing an assembly worker reaches the top of the lifting arm to make there the shearing. This spending and the subsequent cutting in quite airy heights are time consuming and associated with considerable risks for the exporting assembly worker.
Es ist daher Aufgabe der vorliegenden Erfindung, ein Verfahren bereit zu stellen, mit dem eine schnellere Montage des Turmkrans möglich ist und gleichzeitig das Risiko insbesondere für den Montagearbeiter, der die Einschervorgänge an der Hubauslegerspitze vornehmen muss, reduziert bzw. sogar beseitigt werden kann. Des Weiteren ist es Aufgabe der Erfindung, einen Turmkran bereitzustellen, der mit dem erfindungsgemäßen Verfahren montierbar ist.It is therefore an object of the present invention to provide a method with which a faster installation of the tower crane is possible and at the same time reduces the risk especially for the assembly worker who has to make the Einschervorgänge on the Hubauslegerspitze, or even eliminated. Furthermore, it is an object of the invention to provide a tower crane which can be mounted using the method according to the invention.
Die Aufgabe hinsichtlich des Verfahrens wird dadurch gelöst, dass das Verfahren die folgenden Schritte aufweist:The object with regard to the method is achieved by the method comprising the following steps:
Aufbauen eine Turmkranunterteils bis zu einem Spitzenunterteil in gewünschter Höhe;Build a tower crane base up to a point base at the desired height;
Zusammensetzen eines Hubauslegersystem getrennt vom Turmkranunterteil aufweisend die Schritte: • Bereitstellen eines Hubauslegers;Assembly of a jib system separate from the tower crane base, comprising the steps of: • providing a jib;
BESTÄTIGUNGSKOPIE • Montieren eines Hubwerks am Hubausleger;CONFIRMATION COPY • mounting a hoist on the lifting arm;
• Montieren eines Katzfahrwerks am Hubausleger;• Mount a trolley on the lifting arm;
• Einscheren eines Hubseils des Hubwerks am Hubausleger;• shearing a lifting cable of the hoist on the lifting arm;
• Einscheren eines Katzfahrseils am Hubausleger; Verbinden des Hubauslegersystems mit dem Spitzenunterteil und anschließend Aufbauen eines Gegenauslegers und Verbinden des Gegenauslegers mit den bereits montierten Kranteilen.• shearing a trolley rope on the lifting arm; Connecting the lifting arm system with the tip base and then building a counter-jib and connecting the counter jib with the already mounted crane parts.
Vorteilhaft dabei ist, dass das Hubauslegersystem bereits während des Aufbaus des Kranunterteils beispielsweise am Boden montiert werden kann und sämtliche Einscherarbeiten am Boden vorgenommen werden können, wodurch das Befahren des Hubauslegers bis zur Spitze durch einen Montagearbeiter zum Einscheren der Seile wegfällt. Das Montieren des Auslegersystems am Turmkranunterteil ist schnell vorzunehmen, so dass sich die Gesamtmontagezeit des Turmkranes erheblich reduziert.The advantage here is that the lifting arm system can already be mounted during the construction of the crane base, for example, on the ground and all Einscherarbeiten can be made on the ground, thereby eliminating the driving of the lifting arm to the top by an assembly worker for shearing the ropes. The mounting of the boom system on the tower crane base is to be made quickly, so that the total assembly time of the tower crane is significantly reduced.
Eine vorteilhafte Ausführungsform der Erfindung sieht vor, dass der Hubausleger aus einzelnen Modulen zusammengesetzt wird. Dieses Zusammensetzen aus einzelnen Modulen erleichtert den Antransport der Bestandteile des Turmkranes zum Montageort.An advantageous embodiment of the invention provides that the lifting arm is composed of individual modules. This assembly of individual modules facilitates the transport of the components of the tower crane to the installation site.
Hinsichtlich des erfindungsgemäßen spitzenlosen Turmkranes sieht die erfindungsgemäße Lösung vor, dass das Hubauslegersystem so ausgelegt ist, dass der Turmkran nach Montage des Hubauslegersystems und vor der Montage des Gegenauslegers stabil steht. Durch ein gezieltes Auslegen des Hubauslegersystem dahingehend, dass ein stabiler Stand nach der Montage möglich ist, bevor ein Gegenausleger montiert wird, reduziert sich die Montagezeit erheblich.With regard to the centerless tower crane according to the invention, the solution according to the invention provides that the lifting boom system is designed so that the tower crane is stable after installation of the lifting boom system and prior to assembly of the counter-jib. By a targeted design of the lifting arm system to the effect that a stable state after installation is possible before a counter-jib is mounted, the assembly time is reduced considerably.
Eine weitere vorteilhafte Lehre der Erfindung sieht vor, dass der Hubausleger aus einzelnen Modulen zusammengesetzt ist. Als besonders vorteilhaft erweist sich die Erfindung, wenn es sich bei dem Turmkran um einen Turmdrehkran handelt.A further advantageous teaching of the invention provides that the lifting arm is composed of individual modules. The invention proves to be particularly advantageous when the tower crane is a tower crane.
Weitere Vorteile der Erfindung werden anhand der nachfolgend für eine bevorzugte Ausführungsform gestalteten Zeichnung näher erläutert. Dabei zeigt:Further advantages of the invention will be explained in more detail with reference to the drawing designed below for a preferred embodiment. Showing:

At the side facing away from a crane base 20 side is a fixed point 16 for the hoist rope 13. The hoist rope 13 is in communication with the lower block of the trolley 12 and the fixed point sixteenth
In Figur 2 ist die Montage des Hubauslegersystems 10 mit dem Turmunterteil 20 dargestellt. Das Kranunterteil 20 umfasst eine Grundplatte 22, auf der ein seiner Höhe anpassbaren Turm 23 angebracht ist, an dessen oberen Ende sich ein Schwenkwerk 25 mit einem drehbaren Schwenkteil (Drehrahmen) 24 befindet. Ebenfalls dort angeordnet ist das Spitzenunterteil 21. Auf dem oberen Ende wird, wie dargestellt, das Hubauslegersystem 10, das durch einen mobiles Kranfahrzeug 30 auf die gewünschte Höhe angehoben worden ist, in Pfeilrichtung A auf das Kranunterteil 20 abgesenkt und anschließend mit dem Kranunterteil 20 verbunden. Anschließend wird das mobile Kranfahrzeug 30 von dem Hubauslegersystem 10 getrennt und der so entstehende Teilkran, bestehend aus dem Kranunterteil 20 und dem Hubauslegersystem 10, steht frei, da die Auslegung der Bauteile hierfür speziell vorgenommen wurde. Das in der Figur 2 montierte Hubauslegersystem 10 entspricht dem in der Figur 1 erklärten. Sämtliche Antriebe, bewegliche Teile und die dafür notwendigen Seile befinden sich bereits vollständig montiert innerhalb des Systems 10 und sind abgesehen von kleineren Einstellarbeiten einsatzfähig, nachdem die Energie zuvor bereitgestellt wurde. Um sicherzustellen, dass die Standstabilität des Turmkranes auch im Volllastbetrieb gewährleistet ist, wird ein Gegenausleger 40 montiert. Dieses ist in Figur 3 dargestellt. Der Gegenausleger 40 ist vom mobilen Kranfahrzeug 30 bereits auf die gewünschte Höhe angehoben worden. Der Gegenausleger 40 wird dann in Pfeilrichtung B an den Hubausleger herangeführt und mit diesem verbunden. Das Verbinden entsteht beispielsweise durch das Anbringen von Bolzen. Anschließend können noch Gegengewichte montiert werden. Anschließend wird die Energieversorgung für den am Hubausleger 10 befindlichen Antrieben bereitgestellt und der Turmdrehkran 100 ist nach weiteren Feineinstellarbeiten einsatzbereit. FIG. 2 shows the assembly of the lifting arm system 10 with the tower lower part 20. The lower crane part 20 comprises a base plate 22, on which a height-adjustable tower 23 is mounted, at the upper end of which a slewing mechanism 25 with a rotatable pivoting part (rotating frame) 24 is located. Also arranged there is the tip base 21. At the upper end, as shown, the lifting boom system 10, which has been raised by a mobile crane vehicle 30 to the desired height, lowered in the direction of arrow A on the crane base 20 and then connected to the crane base 20 , Subsequently, the mobile crane vehicle 30 is separated from the lifting boom system 10 and the resulting sub-crane, consisting of the crane base 20 and the lifting boom system 10, is free, since the design of the components was specifically made for this purpose. The lifting boom system 10 mounted in FIG. 2 corresponds to that explained in FIG. All of the drives, moving parts, and ropes necessary for them are already fully assembled within the system 10 and, apart from minor adjustments, are operational after the power has been previously provided. To ensure that the stability of the tower crane is guaranteed even in full load operation, a counter-jib 40 is mounted. This is shown in FIG. The counterjib 40 has already been lifted by the mobile crane vehicle 30 to the desired height. The counter-jib 40 is then brought in the direction of arrow B to the lifting arm and connected thereto. The connection arises for example by the attachment of bolts. Afterwards counterweights can be mounted. Subsequently, the power supply is provided for the drives located on the lifting arm 10 and the tower crane 100 is ready for use after further fine tuning.
