Description

Turmdrehkran mit Turmaufbau aus mehreren Turmstücken  Tower crane with tower structure made up of several tower sections
Die vorliegende Erfindung betrifft einen Turmdrehkran nach dem Oberbegriff des Anspruchs 1. The present invention relates to a tower crane according to the preamble of claim 1.
Gattungsgemäße Turmdrehkrane umfassen einen Kranturm und einen an dessen oberem Ende angeordneten Kranausleger. Bei Obendrehkranen ist der Ausleger, welcher typischerweise einen Hauptausleger und einen Gegenausleger umfasst, über ein Drehwerk mit dem oberen Ende des Kranturms verbunden, während bei Untendrehkranen Turm und Ausleger starr miteinander verbunden sind und der Kranturm auf einem drehbaren Unterwagen steht. Tower cranes of the generic type comprise a crane tower and a crane boom arranged at its upper end. In top-slewing cranes, the jib, which typically comprises a main jib and a counter jib, is connected to the upper end of the crane tower via a slewing gear, while in the case of bottom-slewing cranes, the tower and jib are rigidly connected to one another and the crane tower stands on a rotating undercarriage.
Bei der Konstruktion hoher Bauwerke werden entsprechend hohe Krane mit Ha- kenhöhen von teilweise über 100 m benötigt. Häufig bedient man sich dabei der Möglichkeit, Krane an dem in der Konstruktion befindlichen Bauwerk zu verankern oder abzuspannen und die Höhe des Krans bzw. dessen Hakenhöhe durch„Klet- tern“ zu erhöhen. Der Begriff „Klettern“ bezeichnet hierbei das nachträgliche Ein- bringen von Turmstücken in den Kranturm, um die Höhe des Krans an die zuneh- mende Höhe des Bauwerks anzupassen. Problematisch sind jedoch Fälle, bei denen eine Verankerung bzw. ein Abspannen des Krans an dem in Konstruktion befindlichen Bauwerk nicht möglich ist, bei- spielsweise bei einer Verwendung von Fertigbauteilen, welche die erforderlichen Abspannkräfte nicht aufnehmen können. In solchen Fällen müssen demnach frei- stehende Kranaufbauten verwendet werden. Gerade die zunehmende Verwendung von Fertigbetonteilen bei hohen Gebäuden stellt daher eine große Herausforderung für die Verwendung entsprechend hoher Krane dar. Correspondingly high cranes with hook heights of sometimes over 100 m are required for the construction of tall structures. Often one uses the possibility of anchoring or anchoring cranes to the structure under construction and increasing the height of the crane or its hook height by “climbing”. The term “climbing” here means the subsequent insertion of tower sections into the crane tower in order to adapt the height of the crane to the increasing height of the structure. However, cases are problematic in which anchoring or anchoring of the crane on the structure under construction is not possible, for example when using prefabricated components which cannot absorb the required anchoring forces. In such cases, free-standing crane structures must be used. The increasing use of precast concrete parts in tall buildings is therefore a major challenge for the use of appropriately tall cranes.
Um bei freistehenden Kranen dennoch große Höhen zu erreichen, besteht die Mög- lichkeit, das untere Ende des mit dem Ausleger verbundenen Kranturms bzw. Turmstücks mittels eines Übergangsstücks mit einem zusätzlichen Turmstück mit größeren Außenabmessungen zu verbinden. Jedoch ist der zusätzliche breitere Kranturm äußerst kostenintensiv und es besteht häufig eine geringe Verfügbarkeit. In order to reach great heights with free-standing cranes, it is possible to connect the lower end of the crane tower or tower section connected to the jib by means of a transition piece with an additional tower section with larger external dimensions. However, the additional wider crane tower is extremely expensive and there is often little availability.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Turmdrehkran mit einer großen Hakenhöhe bereitzustellen, dessen Turmaufbau auf kostengünsti- gen und gut verfügbaren Bauteilen basiert. The object of the present invention is therefore to provide a tower crane with a large hook height, the tower structure of which is based on inexpensive and readily available components.
Erfindungsgemäß wird diese Aufgabe durch einen Turmdrehkran mit den Merkma- len des Anspruchs 1 gelöst. Demnach ist ein Turmdrehkran mit einem Turmaufbau vorgesehen, an dessen oberem Ende ein Ausleger angeordnet ist, wobei erfin- dungsgemäß wenigstens ein Teil des Turmaufbaus von mindestens drei nebenei- nander angeordneten, parallelen Turmstücken gebildet wird. According to the invention, this object is achieved by a tower crane with the features of claim 1. Accordingly, a tower crane with a tower structure is provided, at the upper end of which a jib is arranged, wherein according to the invention at least part of the tower structure is formed by at least three parallel tower sections arranged next to one another.
Die erfindungsgemäße Idee besteht darin, wenigstens einen Teil des Turmaufbaus eines Turmdrehkrans aus mehreren einzelnen Krantürmen bzw. Turmstücken zu- sammenzustellen und dadurch eine größere Hakenhöhe des Krans zu erreichen. Dabei handelt es sich bei den mindestens drei parallelen Turmstücken vorzugswei- se um Krantürme bzw. Turmstücke von anderen Krantypen, insbesondere kleineren Krantypen. Ein derartiger Turmaufbau ermöglicht es, Turmstücke von anderen, ide- alerweise gut verfügbaren Kransystemen zu verwenden und erreicht dabei die not- wendige Stabilität, um einen Turmaufbau mit großer Höhe zu realisieren. Vorteilhafte Ausführungsformen der Erfindung ergeben sich aus den Unteransprü- chen und der nachfolgenden Beschreibung. The idea according to the invention consists in assembling at least part of the tower structure of a tower crane from a plurality of individual crane towers or tower sections and thereby achieving a greater hook height for the crane. The at least three parallel tower sections are preferably crane towers or tower sections of other crane types, in particular smaller crane types. Such a tower structure makes it possible to use tower sections from other, ideally readily available, crane systems and at the same time achieves the necessary stability to implement a tower structure with a great height. Advantageous embodiments of the invention result from the subclaims and the following description.
In einer Ausführungsform ist vorgesehen, dass ein Teil des Turmaufbaus von ei- nem einzelnen Turmstück gebildet wird, welches vorzugsweise breiter als jedes der mindestens drei parallelen Turmstücke ausgebildet ist. Das einzelne Turmstück befindet sich dabei insbesondere oberhalb der mindestens drei parallelen Turmstü- cke. In one embodiment it is provided that part of the tower structure is formed by a single tower section, which is preferably wider than each of the at least three parallel tower sections. The individual tower section is located above the at least three parallel tower sections.
Die Verwendung von kleineren parallel nebeneinander angeordneten Turmstücken ermöglicht eine wirtschaftlich vorteilhafte Verlängerung des Turmaufbaus von Turmdrehkranen. Beispielsweise können für die kleineren Turmstücke Krantürme von kleineren Kransystemen zum Einsatz kommen. Dies ist insbesondere dann wirtschaftlich vorteilhaft, wenn die kleineren Kransysteme ohnehin vorhanden und beispielsweise wegen geringer Auslastung wenig im Einsatz sind. Mehrere parallel nebeneinander angeordnete kleinere Turmstücke erreichen ferner oftmals eine hö- here Stabilität als ein einzelnes breiteres Turmstück. The use of smaller tower sections arranged parallel to one another enables an economically advantageous extension of the tower structure of tower cranes. For example, crane towers from smaller crane systems can be used for the smaller tower sections. This is particularly economically advantageous if the smaller crane systems are available anyway and are not used very often, for example due to low capacity utilization. Several smaller tower sections arranged parallel to one another often also achieve greater stability than a single wider tower section.
In einer weiteren Ausführungsform ist vorgesehen, dass oberhalb der mindestens drei parallelen Turmstücke ein Übergangsstück angeordnet ist, welches diese mit- einander verbindet. In a further embodiment it is provided that a transition piece is arranged above the at least three parallel tower pieces, which connects these to one another.
In einer weiteren Ausführungsform ist vorgesehen, dass das Übergangsstück eine sich nach oben verjüngende konische Form aufweist und vorzugsweise als Git- terelement, als Turmstück oder als Rahmen, beispielsweise als Blechkonstruktion, ausgeführt ist. In a further embodiment it is provided that the transition piece has a conical shape tapering upwards and is preferably designed as a lattice element, as a tower piece or as a frame, for example as a sheet metal construction.
In einer weiteren Ausführungsform ist vorgesehen, dass das Übergangsstück die mindestens drei parallelen Turmstücke mit einem einzelnen Turmstück verbindet, wobei das einzelne Turmstück vorzugsweise breiter als jedes der parallelen Turm- stücke ausgebildet ist. Das Übergangsstück fungiert also quasi als Adapterstück, welches den dickeren Kranturm bzw. das einzelne Turmstück mit den mindestens drei parallelen Turm- stücken verbindet. Alternativ kann auch vorgesehen sein, dass der Kranausleger direkt an dem Übergangsstück, entweder drehbar oder starr, befestigt ist. In diesem Fall wird der gesamte Turmaufbau von den mindestens drei parallelen Turmstücken und dem Übergangsstück gebildet. In a further embodiment it is provided that the transition piece connects the at least three parallel tower pieces with a single tower piece, the single tower piece preferably being wider than each of the parallel tower pieces. The transition piece thus functions as an adapter piece, which connects the thicker crane tower or the individual tower piece with the at least three parallel tower pieces. Alternatively, it can also be provided that the crane boom is attached directly to the transition piece, either rotatably or rigidly. In this case, the entire tower structure is formed by the at least three parallel tower sections and the transition piece.
In einer weiteren Ausführungsform ist vorgesehen, dass die mindestens drei paral- lelen Turmstücke über Fundamentanker mit einem Fundamentkreuz oder einem Unterwagen verbunden sind. Möglich ist auch, dass ein weiteres unteres Über- gangsstück vorgesehen ist, welches die unteren Enden der mindestens drei paral- lelen Turmstücke miteinander verbindet und welches wiederum mit dem Funda- mentkreuz oder Unterwagen verbunden ist. In diesem Fall ergäbe sich eine beson- ders einfache Nachrüstbarkeit des erfindungsgemäßen Turmdrehkrans. Zum Nach- rüsten wird einfach der einzelne breitere Kranturm von dem Fundamentkreuz oder Unterwagen gelöst und die zwischen den oberen und unteren Übergangsstücken angeordneten mindestens drei parallelen Turmstücke eingefügt. In a further embodiment it is provided that the at least three parallel tower sections are connected to a foundation cross or an undercarriage via foundation anchors. It is also possible for a further lower transition piece to be provided which connects the lower ends of the at least three parallel tower pieces to one another and which in turn is connected to the foundation cross or undercarriage. In this case, the tower crane according to the invention would be particularly easy to retrofit. For retrofitting, the single wider crane tower is simply detached from the foundation cross or undercarriage and the at least three parallel tower pieces arranged between the upper and lower transition pieces are inserted.
In einer weiteren Ausführungsform ist vorgesehen, dass die mindestens drei paral- lelen Turmstücke eigenständige Krantürme oder zumindest Teile davon darstellen, welche in anderen Turmdrehkranen einsetzbar sind. In a further embodiment it is provided that the at least three parallel tower sections represent independent crane towers or at least parts thereof, which can be used in other tower cranes.
In einer weiteren Ausführungsform ist vorgesehen, dass das breitere einzelne Turmstück einen eigenständigen Kranturm oder zumindest einen Teil davon dar- stellt, welcher in einem anderen Turmdrehkran einsetzbar ist. In a further embodiment it is provided that the wider individual tower section represents an independent crane tower or at least a part thereof, which can be used in another tower crane.
In einer weiteren Ausführungsform ist vorgesehen, dass die mindestens drei paral- lelen Turmstücke durch Aussteifungen miteinander verbunden sind. Dadurch wird die Stabilität des erfindungsgemäßen Turmaufbaus weiter erhöht. Dabei kann vor- gesehen sein, dass die einzelnen Turmstücke durch Querstreben, Versteifungen, Gitterstücke oder andere Aussteifungselemente untereinander verbunden sind. Die vorliegende Erfindung umfasst weiterhin ein Übergangsstück zur Verbindung von mindestens drei parallelen Turmstücken eines Turmdrehkrans gemäß einem der Ansprüche 3 bis 5. In a further embodiment it is provided that the at least three parallel tower sections are connected to one another by stiffeners. This further increases the stability of the tower structure according to the invention. It can be provided that the individual tower sections are connected to one another by cross struts, stiffeners, lattice sections or other stiffening elements. The present invention further comprises a transition piece for connecting at least three parallel tower pieces of a tower crane according to one of claims 3 to 5.

In der Figur 1 ist ein Ausführungsbeispiel des erfindungsgemäßen Turmdrehkrans 10 in einer Seitenansicht dargestellt. Der Turmdrehkran 10 ist als Obendrehkran ausgeführt und weist einen Turmaufbau 2 auf, an dessen oberem Ende ein Ausle- ger 8, bestehend aus Flauptausleger und Gegenausleger, über ein Drehwerk dreh- bar befestigt ist. 1 shows an embodiment of the tower crane 10 according to the invention in a side view. The tower crane 10 is designed as a top slewing crane and has a tower structure 2, at the upper end of which a boom 8, consisting of a flail boom and counter jib, is rotatably attached via a slewing gear.
Der Turmaufbau 2 weist drei Abschnitte auf. Der obere Abschnitt, welcher mit dem Ausleger 8 verbunden ist, wird durch ein einzelnes Turmstück 7 gebildet. Der unte- re Abschnitt, welcher mit dem Kranfundament 3 verbunden ist, wird durch vier ne- beneinander angeordnete, parallele Turmstücke 1 gebildet, welche jeweils eine ge- ringere Breite bzw. Außenumfang als das einzelne Turmstück 7 aufweisen. Die kleineren Turmstücke 1 bilden dabei die Ecken eines Quadrats und sind über ein konisch geformtes Übergangsstück 6 (mittlerer Abschnitt) mit dem einzelnen breite- ren Turmstück 7 verbunden. Zur Erhöhung der Stabilität sind die kleineren Turm- stücke 1 durch zusätzliche Aussteifungen 5 miteinander verbunden. The tower structure 2 has three sections. The upper section, which is connected to the boom 8, is formed by a single tower piece 7. The lower section, which is connected to the crane foundation 3, is formed by four parallel tower pieces 1 arranged next to one another, each of which has a smaller width or outer circumference than the individual tower piece 7. The smaller tower sections 1 form the corners of a square and are connected to the individual wide sections via a conically shaped transition piece 6 (middle section). ren tower section 7 connected. To increase the stability, the smaller tower pieces 1 are connected to one another by additional stiffeners 5.
Die kleineren Turmstücke 1 sind über Fundamentanker 4 mit einem Kranfundament 3 verbunden, bei welchem es sich beispielsweise um ein Fundamentkreuz handeln kann. Bei dem erfindungsgemäßen Turmdrehkran 10 kann es sich alternativ um einen Untendrehkran handeln. In diesem Fall können die kleineren Turmstücke 1 mit einem drehbaren Unterwagen des Krans 10 verbunden sein. Möglich ist eben- falls, dass die kleineren Turmstücke 1 mit einem weiteren Übergangsstück verbun- den sind, welches wiederum mit einem Fundamentkreuz oder Unterwagen verbun- den ist. The smaller tower sections 1 are connected via foundation anchors 4 to a crane foundation 3, which can be, for example, a foundation cross. The tower crane 10 according to the invention can alternatively be a bottom crane. In this case, the smaller tower sections 1 can be connected to a rotatable undercarriage of the crane 10. It is also possible for the smaller tower sections 1 to be connected to a further transition piece, which in turn is connected to a foundation cross or undercarriage.
In der Figur 2a ist ein durch die mit„A“ markierten Pfeile gekennzeichneter Schnitt (Draufsicht) durch den unteren Abschnitt des Turmaufbaus 2 dargestellt. Es ist zu erkennen, dass die vier parallelen Turmstücke 1 die Ecken eines Quadrats bilden, wodurch eine hohe Stabilität des Turmaufbaus 2 gewährleistet wird. FIG. 2a shows a section (top view) through the lower section of the tower structure 2 identified by the arrows marked “A”. It can be seen that the four parallel tower pieces 1 form the corners of a square, which ensures a high stability of the tower structure 2.
Eine alternative Ausführungsform mit lediglich drei kleineren parallelen Turmstü- cken 1 ist in der Figur 2b gezeigt, welche die gleiche Querschnittsansicht wie die Figur 2a repräsentiert. Die drei kleineren Turmstücke 1 sind hier gedreht zueinan- der platziert und bilden die Ecken eines gleichseitigen Dreiecks. Flierdurch wird ebenfalls eine hohe Stabilität erreicht, wobei ein kleineres Turmstück 1 weniger zum Einsatz kommt als bei dem Ausführungsbeispiel der Figuren 1 und 2a. Aller dings ist es auch möglich, je nach Anforderung an Stabilität, Hakenhöhe, Wirt- schaftlichkeit, etc. eine andere Anzahl oder Anordnung der kleineren Turmstücke 1 für den Turmaufbau 2 zu verwenden. An alternative embodiment with only three smaller parallel tower sections 1 is shown in FIG. 2b, which represents the same cross-sectional view as FIG. 2a. The three smaller tower sections 1 are placed rotated to each other and form the corners of an equilateral triangle. A high level of stability is also achieved in this way, a smaller tower section 1 being used less than in the exemplary embodiment in FIGS. 1 and 2a. However, it is also possible to use a different number or arrangement of the smaller tower pieces 1 for the tower structure 2, depending on the requirements for stability, hook height, economy, etc.
Der Erfindung liegt die Einsicht zugrunde, dass mehrere kleinere Turmstücke 1 eine stabilere Kranturmkonfiguration ermöglichen können als ein einzelnes breiteres bzw. stärkeres Turmstück 7. Darüber hinaus sind kleinere Turmstücke 1 anderer Kransysteme typischerweise günstiger und besser auf dem Markt verfügbar als größere Krantürme 7. Oftmals werden Turmstücke 1 kleinerer Kransysteme unge- nutzt bereitgehalten und können somit einfach und kostengünstig in dem Turmauf- bau 2 eines erfindungsgemäßen Turmdrehkrans 10 zum Einsatz kommen. The invention is based on the insight that several smaller tower sections 1 can enable a more stable crane tower configuration than a single wider or stronger tower section 7. In addition, smaller tower sections 1 of other crane systems are typically cheaper and more readily available on the market than larger crane towers 7. Often Tower sections 1 of smaller crane systems uses ready and can therefore be used easily and inexpensively in the tower structure 2 of a tower crane 10 according to the invention.
Beispielsweise kann durch die Verwendung von vier Turmstücken 1 vom Typ Lieb- herr 120 HC ein Turmsystem konstruiert werden, welches stärker bzw. stabiler und bezogen auf den Meterpreis kostengünstiger ist als ein einzelner größerer Kranturm vom Typ 1250 HC. Dadurch ist es z.B. möglich, freistehende Krane vom Typ Lieb- herr 550 / 630 / 1000 EC-H mit Hakenhöhen von über 100 m bereitzustellen. Dar- über hinaus sind beispielsweise kleinere Turmstücke vom Typ 120 HC wirtschaftli- cher in der Montage und auf dem Markt besser verfügbar als größere Turmstücke vom Typ 1250 HC. For example, by using four tower sections 1 of the Liebherr 120 HC type, a tower system can be constructed which is stronger or more stable and, based on the price per meter, less expensive than a single larger crane tower of the 1250 HC type. This makes it e.g. It is possible to provide free-standing cranes of the Liebherr 550/630/1000 EC-H type with hook heights of over 100 m. In addition, smaller 120 HC tower sections, for example, are more economical to assemble and more readily available on the market than larger 1250 HC tower sections.
