Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Winkelverstellung eines Auslegersystems von Kranen sowie einen Kran mit einer derartigen Vorrichtung.The invention relates to a method and a device for angular adjustment of a boom system of cranes and a crane with such a device.

Durch offenkundige Vorbenutzung ist bekannt, dass ein Kran ein Auslegersystem aufweist, an das eine Verlängerung und/oder eine Abwinkelung angebracht werden kann. Die EP 1 477 451 A2 , die DE 36 42 248 A1 , die US 3,085,695 , die US 4,653,655 , die WO 83/03816 A1 , die WO 02/076 874 A1 , die US 5,842,587 , die SU 179 13 53 A1 und die WO 2009/026 870 A1 (entspricht DE 20 2007012204 U1 ) offenbaren Vorrichtungen, mittels derer eine Winkelstellung eines Auslegersystems veränderbar ist. Nachteilig ist, dass die Winkelverstellung des Auslegersystems oftmals weiterer Hilfsmittel und/oder Zwischenschritte bedarf. Ein schneller und einfach zu handhabender Wechsel von einer Winkelstellung in eine andere ist mit den genannten Vorrichtungen nicht möglich.By obvious prior use, it is known that a crane has a boom system to which an extension and / or a bend can be attached. The EP 1 477 451 A2 , the DE 36 42 248 A1 , the US 3,085,695 , the US 4,653,655 , the WO 83/03816 A1 , the WO 02/076 874 A1 , the US 5,842,587 , the SU 179 13 53 A1 and the WO 2009/026870 A1 (equivalent to DE 20 2007012204 U1 ) disclose devices by means of which an angular position of a boom system is changeable. The disadvantage is that the angle adjustment of the boom system often requires further aids and / or intermediate steps. A quick and easy to handle change from one angular position to another is not possible with the devices mentioned.

Es ist daher die Aufgabe der Erfindung, ein Verfahren zur Winkelverstellung eines Auslegersystems von Kranen derart zu gestalten, dass ein Wechsel von einer Ausgangs-Winkelstellung in mehrere davon verschiedene Winkelstellungen möglich ist, wobei der Wechsel zwischen zwei Winkelstellungen schnell umzusetzen und einfach zu handhaben ist.It is therefore an object of the invention to design a method for angular adjustment of a boom system of cranes so that a change from an initial angular position in several different angular positions is possible, with the change between two angular positions quickly implement and easy to handle.

Diese Aufgabe ist erfindungsgemäß durch ein Verfahren mit den im Anspruch 1 angegebenen Merkmalen gelöst.This object is achieved by a method having the features specified in claim 1.

Erfindungsgemäß wurde erkannt, dass zwei miteinander verbundene Ausleger-Einheiten eines Auslegersystems von einer Ausgangs-Winkelstellung in eine davon verschiedene Winkelstellung mittels Verbindungs-Laschen überführbar sind, indem die Verbindungs-Laschen in der AusgangsWinkelstellung derart angeordnet sind, dass Anfangs-Öffnungen der Verbindungs-Laschen und Ziel-Öffnungen der Verbindungs-Laschen jeweils paarweise zum Durchstecken eines die Ausleger-Einheiten verbindenden Verbindungs-Elements fluchten. Das Auslegersystem wird in der Ausgangs-Winkelstellung durch das Verbindungs-Element, das in einem Paar fluchtender Anfangs-Öffnungen angeordnet ist, gehalten, wobei zum Wechsel in eine Ziel-Winkelstellung zunächst das Verbindungs-Element entlastet, anschließend aus dem Paar der fluchtenden Anfangs-Öffnungen entfernt und schließlich in einem weiteren von dafür vorgesehenen Paaren fluchtender Ziel-Öffnungen zum Verbinden derselben angeordnet wird. Damit kann ausgehend von der Ausgangs-Winkelstellung durch einfache Bedienung, insbesondere durch Einhandbedienung, eine gewünschte Ziel-Winkelstellung aus mehreren möglichen ausgewählt und eingestellt werden.According to the invention it has been recognized that two interconnected boom units of a boom system from an initial angular position in a different angular position thereof by means of connecting tabs can be converted by the connecting tabs are arranged in the AusgangsWinkelstellung such that initial openings of the connecting tabs and target openings of the connecting tabs in pairs for the passage of a connecting the boom units Align connection element. The cantilever system is held in the initial angular position by the linkage member disposed in a pair of aligned starting apertures, initially relieving the linkage member to change to a target angular position, and then disengaging from the pair of aligned camming studs. Apertures removed and finally in a further provided by pairs of aligned target openings for connecting the same is arranged. Thus, starting from the initial angular position by simple operation, in particular by one-hand operation, a desired target angular position can be selected and set from a plurality of possible ones.

Mit einem Verfahren gemäß Anspruch 2 können besonders bevorzugte Winkelstellungen schnell und direkt eingestellt werden.With a method according to claim 2 particularly preferred angular positions can be adjusted quickly and directly.

Die Winkelverstellung mit einem Verfahren gemäß Anspruch 3 ermöglicht eine einfache Relativbewegung zwischen den beiden Ausleger-Einheiten.The angular adjustment with a method according to claim 3 allows a simple relative movement between the two boom units.

Mit einem Verfahren gemäß Anspruch 4 ist eine Winkelverstellung der Ausleger-Einheiten ohne weitere Hilfsmittel möglich.With a method according to claim 4, an angular adjustment of the boom units is possible without further aids.

Durch ein Verfahren gemäß Anspruch 5 wird ein Verbindungs-Element in besonders einfacher Weise entlastet.By a method according to claim 5, a connection element is relieved in a particularly simple manner.

Darüber hinaus sind bislang bekannte winkelverstellbare Auslegersysteme zumeist aufwendig konstruiert und beanspruchen deshalb einen großen Bauraum, insbesondere in der Ausgangs-Winkelstellung der Auslegersysteme. Dadurch kann die Gesamtlänge eines Krans, an den das Auslegersystem montiert ist, eine zulässige Gesamtlänge überschreiten, so dass ein Straßentransport des Krans nicht möglich ist.In addition, previously known angle-adjustable cantilever systems are usually designed consuming and therefore require a large amount of space, especially in the output angular position of the boom systems. As a result, the total length of a crane, to which the boom system is mounted, exceed a permissible total length, so that a road transport of the crane is not possible.

Es ist eine weitere Aufgabe der Erfindung, eine Vorrichtung zur Winkelverstellung eines Auslegersystems von Kranen derart zu gestalten, dass ein Wechsel von einer Ausgangs-Winkelstellung zu einer Ziel-Winkelstellung schnell, kostengünstig und unter Erhaltung der Stabilität des Auslegersystems ermöglicht wird, wobei das Auslegersystem, insbesondere in der Ausgangs-Winkelstellung, eine Baugröße derart aufweist, dass der Straßentransport eines Krans mit montiertem Auslegersystem möglich ist.It is a further object of the invention to provide an apparatus for angular adjustment of a boom system of cranes so as to enable a change from an initial angular position to a target angular position quickly, inexpensively and maintaining the stability of the boom system, the boom system comprising especially in the initial angular position, a size such that the road transport of a crane with mounted boom system is possible.

Diese Aufgabe ist erfindungsgemäß durch ein winkelverstellbares Auslegersystem mit den im Anspruch 6 angegebenen Merkmalen gelöst.This object is achieved by a angle-adjustable boom system with the features specified in claim 6.

Erfindungsgemäß wurde erkannt, dass eine Ausleger-Einheit eine Verbindungs-Lasche mit mehreren Öffnungen aufweist, wobei die Verbindungs-Laschen der Ausleger-Einheiten in der Ausgangs-Winkelstellung derart angeordnet sind, dass Längsachsen der Ausleger-Einheiten parallel angeordnet sind und Anfangs-Öffnungen der Ausleger-Einheiten und Ziel-Öffnungen der Ausleger-Einheiten jeweils paarweise zum Durchstecken eines die Ausleger-Einheiten verbindenden Verbindungs-Elements miteinander fluchten. In dieser Anordnung bilden die beiden Ausleger-Einheiten ein fluchtendes Auslegersystem. Jede Verbindungs-Lasche weist zwei Schenkel auf, die in einem Winkel zueinander angeordnet sind, wobei der erste Schenkel eine Anfangs-Öffnung zur Verbindung der Verbindungs-Laschen mit dem Verbindungs-Element in der Ausgangs-Winkelstellung und der zweite Schenkel mehrere Ziel-Öffnungen zur Verbindung der Verbindungs-Laschen mit dem Verbindungs-Element in verschiedenen Ziel-Winkelstellungen aufweist.According to the invention, it has been recognized that a boom unit has a connecting lug with a plurality of openings, wherein the connecting lugs of the boom units are arranged in the output angular position such that longitudinal axes of the boom units are arranged in parallel and initial openings of the Boom units and target openings of the boom units are aligned in pairs for insertion of a connecting element connecting the boom units with each other. In this arrangement, the two boom units form an aligned boom system. Each connecting lug has two legs which are arranged at an angle to each other, wherein the first leg has an initial opening for connecting the connecting tabs having the connection element in the initial angular position and the second leg having a plurality of target openings for connecting the connection tabs with the connection element in different target angular positions.

Ein Auslegersystem gemäß Anspruch 7 ermöglicht die Auswahl aus zwei verschiedenen Ziel-Winkelstellungen.A boom system according to claim 7 allows selection from two different target angular positions.

Durch Gestaltungen des Auslegersystems nach Anspruch 8 sind zwei besonders bevorzugte Winkelstellungen schnell und einfach einstellbar. Ein Abstand der Anfangs-Öffnung zu der Scheitelpunkts-Öffnung und Abstände der Ziel-Öffnungen zu der Scheitelpunkts-Öffnung können derart festgelegt werden, dass die Längsachsen in verschiedenen Ziel-Winkelstellungen, insbesondere in einer 20°-Winkelstellung oder in einer 40°-Winkelstellung, durch Verbinden der entsprechenden Ziel-Öffnungen durch das Verbindungs-Element zueinander anordenbar sind.By designs of the boom system according to claim 8, two particularly preferred angular positions are quickly and easily adjustable. A distance of the initial opening to the apex opening and distances of the target openings to the apex opening may be set such that the longitudinal axes in different target angular positions, in particular in a 20 ° angular position or in a 40 ° angular position , Can be arranged by connecting the corresponding target openings through the connection element to each other.

Eine Ausgestaltung des Auslegersystems gemäß Anspruch 9 ermöglicht zusätzliche Ziel-Winkelstellungen, ohne dass weitere Verbindungs-Laschen verwendet werden müssen. Dies kann beispielsweise dadurch erreicht werden, dass die Schenkel weitere Ziel-Öffnungen aufweisen, die bei veränderter Winkelanordnung der Schenkel derart fluchten, dass weitere Ziel-Winkelstellungen der Ausleger-Einheiten einstellbar sind. Weitere Ziel-Winkelstellungen können beispielsweise größer als 20° sein, einen Winkelbetrag zwischen 20° und 40° einnehmen oder größer als 40° sein.An embodiment of the boom system according to claim 9 allows additional target angular positions without the need for further connection tabs are used. This can be achieved, for example, by the legs having further target openings, which are aligned with the angle arrangement of the legs in such a way that further target angular positions of the boom units can be set. Further target angular positions may for example be greater than 20 °, occupy an angle between 20 ° and 40 ° or be greater than 40 °.

Die Verwendung von Verbindungs-Laschen gemäß Anspruch 10 erlaubt die Reduzierung des Fertigungs- und damit auch des Kostenaufwandes für die Verbindungs-Laschen. Die erste Verbindungs-Lasche kann ein Blatt mehr als die zweite Verbindungs-Lasche aufweisen, wobei die Verbindungs-Laschen derart versetzt zueinander angeordnet sein können, dass die Blätter der zweiten Verbindungs-Lasche zwischen den Blättern der ersten Verbindungs-Lasche angeordnet sind.The use of connection tabs according to claim 10 allows the reduction of manufacturing and thus also the cost of the connection tabs. The first connection tab may comprise one sheet more than the second connection tab, wherein the connection tabs may be offset from each other such that the sheets of the second connection tab are disposed between the sheets of the first connection tab.

Auslegersysteme gemäß den Ansprüchen 11 und 12 können als Verlängerung für einen Gittermast oder zur Anbindung eines Teleskopauslegerkopfes an einen Gittermast dienen.Jib systems according to claims 11 and 12 can serve as an extension for a lattice mast or for connecting a telescopic boom head to a lattice mast.

Ein Auslegersystem gemäß Anspruch 13 weist in der Ausgangs-Winkelstellung eine geringe Baugröße, insbesondere in Richtung der Längsachsen der Ausleger-Einheiten, auf. Ein Kran, an dem das Auslegersystem montiert ist, kann eine zulässige Gesamtlänge aufweisen und ist deshalb für den Straßenverkehr zugelassen.A boom system according to claim 13 has in the output angular position a small size, in particular in the direction of the longitudinal axes of the boom units, on. A crane on which the boom system is mounted may have a permissible overall length and is therefore approved for use on the road.

Mit einem Auslegersystem gemäß Anspruch 14 wird in der Ausgangs-Winkelstellung eine Schwenkbewegung der Ausleger-Einheiten zueinander entgegen einer beabsichtigten Schwenkrichtung verhindert.With a boom system according to claim 14, a pivoting movement of the boom units to each other against an intended pivoting direction is prevented in the initial angular position.

Bei einem Kran gemäß Anspruch 15 erfolgt eine Winkelverstellung eines Auslegersystems einfach, schnell und damit kostengünstig.In a crane according to claim 15, an angular adjustment of a boom system is simple, fast and therefore cost.

In der Ausgangs-Winkelstellung sind die Verbindungs-Laschen 8, 8a derart angeordnet, dass sowohl die Anfangs-Öffnungen 10 der Verbindungs-Laschen 8, 8a als auch die Ziel-Öffnungen 11 bzw. 12 der Verbindungs-Laschen 8, 8a jeweils paarweise miteinander fluchten. Weiterhin sind die Verbindungs-Laschen 8, 8a durch ein in deren fluchtend angeordnete Anfangs-Öffnungen 10 eingestecktes Verbindungs-Element 20 miteinander verbunden. Da die Anfangs-Öffnungen 10 ebenso wie die Ziel-Öffnungen 11, 12 als Langlöcher ausgebildet sind, ist das in jeweils einem fluchtenden Öffnungspaar 10, 11, 12 eingesteckte Verbindungs-Element 20 bewegbar. Dazu muss das Verbindungs-Element 20 entlastet sein. Der Entlastungsvorgang wird im Weiteren noch erläutert.In the initial angular position, the connection tabs 8, 8a are arranged such that both the initial openings 10 of the connection tabs 8, 8a and the target openings 11 and 12 of the connection tabs 8, 8a in pairs with each other aligned. Furthermore, the connection tabs 8, 8a are connected to one another by a connecting element 20 inserted in their initially arranged openings 10 in alignment. Since the initial openings 10 as well as the target openings 11, 12 are formed as slots, in each case an aligned pair of openings 10, 11, 12 inserted connecting element 20 is movable. For this purpose, the connection element 20 must be relieved. The discharge process will be explained below.

Weiterhin weisen die Verbindungs-Laschen 8, 8a jeweils an dem ersten Schenkel 17 einen Anschlag 22 auf, der mindestens eine Nase 25 mit einer Gewindebohrung 26 und einem darin eingeschraubten Gewindestift 27 umfasst. Der Anschlag 22 liegt in der Ausgangs-Winkelstellung an einem Gabelkopf 28 des jeweils gegenüberliegenden Obergurtes 7 der jeweiligen Ausleger-Einheit 3, 4 an, so dass eine Schwenkbewegung der Ausleger-Einheiten 3, 4 entgegen der Schwenkrichtung 2a in der Ausgangs-Winkelstellung blockiert ist.Furthermore, the connection tabs 8, 8a respectively on the first leg 17 a stop 22 which comprises at least one nose 25 with a threaded bore 26 and a threaded pin 27 screwed therein. The stop 22 is in the initial angular position on a clevis 28 of the respective opposite upper flange 7 of the respective boom unit 3, 4, so that a pivoting movement of the boom units 3, 4 is blocked against the pivoting direction 2a in the initial angular position ,

Ein zentrischer Abstand A1 der Anfangs-Öffnung 10 von der Scheitelpunkts-Öffnung 9 ist kleiner als zentrische Abstände A2, A3 der Ziel-Öffnungen 11, 12 von der Scheitelpunkts-Öffnung 9. Durch eine Variation der Abstände A1, A2, A3 können die resultierenden Ziel-Winkelstellungen eingestellt werden.A central distance A1 of the initial opening 10 from the apex opening 9 is smaller than centric distances A2, A3 of the target openings 11, 12 from the apex opening 9. By varying the distances A1, A2, A3, the resulting Target angular positions can be set.

In der Ausgangs-Winkelstellung weist das Auslegersystem 1 eine horizontale Ausdehnung A4 auf, die durch die Baugröße der Verbindungs-Laschen 8, 8a bestimmt ist. Dabei ist die Ausdehnung A4 kleiner als ein zulässiger Höchstwert, so dass ein Kran mit einem daran montierten Auslegersystem 1 eine für den Straßentransport zulässige Gesamtlänge nicht überschreitet und damit für den Straßentransport zugelassen ist.In the initial angular position, the boom system 1 has a horizontal extent A4, which is determined by the size of the connection tabs 8, 8a. In this case, the extent A4 is smaller than a maximum permissible value, so that a crane with a boom system 1 mounted thereon does not exceed an overall length permissible for road transport and is therefore permitted for road transport.

Im Folgenden wird ein Verfahren zur Winkelverstellung des Auslegersystems 1 erläutert. Dazu wird ausgehend von dem Auslegersystem 1 in der Ausgangs-Winkelstellung gemäß Fig. 1 das Verbindungs-Element 20 durch Anheben oder Abstützen der abzuwinkelnden Ausleger-Einheit 3 entlastet. Das Anheben kann beispielsweise mittels eines nicht dargestellten Hilfskrans, Staplers oder einer sonstigen Hebemaschine erfolgen. Auch das Anheben der Ausleger-Einheit 3 durch eine am Kran befindliche Seilwinde ist möglich. Darüber hinaus kann die Ausleger-Einheit 3 mit einem der Verbindungs-Lasche 8 gegenüberliegenden Ende auf dem Boden abgestützt werden.In the following, a method for angular adjustment of the boom system 1 will be explained. For this purpose, starting from the boom system 1 in the output angular position according to Fig. 1 relieves the connection element 20 by lifting or supporting the angled boom unit 3. The lifting can be done for example by means of an auxiliary crane, forklift, or other hoist, not shown. Also, the raising of the boom unit 3 by a winch located on the crane is possible. In addition, the boom unit 3 can be supported on the ground with an end opposite the connection tab 8.

Durch die Anschläge 22 wird eine Schwenkbewegung der Ausleger-Einheit 3 entgegen der Schwenkrichtung 2a gesperrt. Da die Anfangs-Öffnungen 10 als Langlöcher ausgebildet sind, kann das Verbindungs-Element 20 im entlasteten Zustand einfach und per Hand aus den fluchtenden Anfangs-Öffnungen 10 der Verbindungs-Laschen 8, 8a entnommen werden. Anschließend wird mit dem Verbindungs-Element 20 eines der Paare der fluchtenden Ziel-Öffnungen 11 oder 12 verbunden. Durch Auswahl des zu verbindenden Paares der Ziel-Öffnungen 11 oder 12 wird die daraus resultierende Ziel-Winkelstellung festgelegt.By the stops 22, a pivoting movement of the boom unit 3 is locked against the pivoting direction 2a. Since the initial openings 10 are formed as slots, the connecting element 20 in the unloaded state easily and by hand from the aligned Initial openings 10 of the connection tabs 8, 8a are removed. Subsequently, one of the pairs of aligned target openings 11 or 12 is connected to the connection element 20. By selecting the pair of target ports 11 or 12 to be connected, the resulting target angular position is determined.

Nachdem das Paar fluchtender Ziel-Öffnungen 11 oder 12 durch das Verbindungs-Element 20 miteinander verbunden ist, wird das Verbindungs-Element 20 wieder belastet, indem die angehobene bzw. abgestützte Ausleger-Einheit 3 wieder abgelassen bzw. freigegeben wird. Dadurch öffnet sich die Verbindung der Verbindungs-Laschen 8, 8a an den Anfangs-Öffnungen 10, wobei die Ausleger-Einheiten 3, 4 um die Schwenkeinheit 2 in der Schwenkrichtung 2a so weit schwenken, bis die beiden Scheitelpunkts-Öffnungen 9 und die durch das Verbindungs-Element 20 verbundenen Ziel-Öffnungen 11, 12 auf einer gemeinsamen Geraden 23, 24 angeordnet sind (siehe Fig. 3 und 4).After the pair of aligned target openings 11 or 12 are connected to each other by the connection member 20, the connection member 20 is again loaded by releasing the raised boom unit 3 again. This opens the connection of the connection tabs 8, 8a at the initial openings 10, wherein the boom units 3, 4 about the pivot unit 2 in the pivoting direction 2a so far pivot until the two vertex openings 9 and through the Connection element 20 connected target openings 11, 12 are arranged on a common line 23, 24 (see Fig. 3 and 4 ).

Wie in Fig. 2 schematisch dargestellt, weist die Verbindungs-Lasche 8 drei Blätter 21 und die Verbindungs-Lasche 8a zwei Blätter 21 auf. Die Blätter 21 sind in Richtung des ersten Verbindungs-Elementes 20 parallel und beabstandet zueinander angeordnet. Dabei sind die Verbindungs-Laschen 8, 8a derart versetzt zueinander angeordnet, dass die Blätter 21 der Verbindungs-Lasche 8a zwischen den Blättern 21 der Verbindungs-Lasche 8 angeordnet sind. Die Geometrie der Blätter 21 ist für beide Verbindungs-Laschen 8, 8a identisch, wodurch der Fertigungsaufwand und damit die Herstellkosten für die Verbindungs-Laschen 8, 8a reduziert werden. Die Verbindungs-Laschen 8, 8a und damit deren Blätter 21 können auch verschiedene Geometrien aufweisen.As in Fig. 2 schematically illustrated, the connection tab 8 has three leaves 21 and the connecting tab 8a two leaves 21 on. The leaves 21 are arranged parallel to and spaced from one another in the direction of the first connecting element 20. In this case, the connection tabs 8, 8a are arranged offset from one another in such a way that the leaves 21 of the connection tab 8a are arranged between the leaves 21 of the connection tab 8. The geometry of the blades 21 is identical for both connecting straps 8, 8a, which reduces the production costs and thus the manufacturing costs for the connecting straps 8, 8a. The connection tabs 8, 8a and thus their leaves 21 may also have different geometries.

Das Auslegersystem 1 ist in Fig. 3 in einer ersten Ziel-Winkelstellung und in Fig. 4 in einer zweiten Ziel-Winkelstellung dargestellt. Die erste Ziel-Winkelstellung zeichnet sich dadurch aus, dass die Längsachsen 13, 13a der Ausleger-Einheiten 3, 4 einen Winkel von 20° und in der zweiten Ziel-Winkelstellung einen Winkel von 40° einschließen.The boom system 1 is in Fig. 3 in a first target angular position and in Fig. 4 shown in a second target angular position. The first target angular position is characterized in that the longitudinal axes 13, 13a of the boom units 3, 4 enclose an angle of 20 ° and in the second target angular position an angle of 40 °.

Während in der 20°-Winkelstellung das Verbindungs-Element 20 in den Zielöffnungen 11 angeordnet ist, verbindet das Verbindungs-Element 20 in der 40°-Winkelstellung die Ziel-Öffnungen 12. In der 20°-Winkelstellung sind die Scheitelpunkts-Öffnungen 9 sowie die durch das Verbindungs-Element 20 miteinander verbundenen Ziel-Öffnungen 11 auf einer Geraden 23 und in der 40°-Winkelstellung die beiden Scheitelpunkts-Öffnungen 9 sowie die mittels des Verbindungs-Elementes 20 miteinander verbundenen Ziel-Öffnungen 12 auf einer Geraden 24 angeordnet.While in the 20 ° angular position, the connecting element 20 is arranged in the target openings 11, the connecting element 20 connects in the 40 ° -Winkelstellung the target openings 12. In the 20 ° -Winkelstellung are the apex openings 9 and the target openings 11 connected to one another by the connection element 20 are arranged on a straight line 23 and in the 40 ° angular position the two vertex openings 9 and the target openings 12 connected to one another by means of the connection element 20 on a straight line 24.

Die Fig. 5 und 6 zeigen eine weitere Ausführungsform von Verbindungs-Laschen 29, 29a des Auslegersystems 1. Komponenten, die denjenigen entsprechen, die vorstehend unter Bezugnahme auf die Fig. 1 bis 4 bereits erläutert wurden, tragen die gleichen Bezugsziffern und werden nicht nochmals im Einzelnen diskutiert.The Fig. 5 and 6 show another embodiment of connecting tabs 29, 29a of the cantilever system 1. Components which correspond to those described above with reference to FIGS Fig. 1 to 4 already described, bear the same reference numbers and will not be discussed again in detail.

Wesentlicher Unterschied zu der ersten Ausführungsform des Auslegersystems 1 ist die Gestaltung des Verbindungs-Elementes als Bolzen 30 mit Bajonett-Verschluss. Dazu ist an einem der äußeren Blätter 21 der Verbindungs-Lasche 29 eine Blende 31 angebracht, so dass die Öffnungen 10, 11, 12 durch jeweils einen im Wesentlichen rechteckigen Ausschnitt 32 begrenzt sind. Der Bolzen 30 ist in der Ziel-Öffnung 12 angeordnet, wobei die Verbindungs-Laschen 29, 29a in Fig. 5 in der Ausgangs-Winkelstellung und in Fig. 6 in der 40°-Winkelstellung dargestellt sind.The essential difference from the first embodiment of the boom system 1 is the design of the connecting element as a bolt 30 with bayonet closure. For this purpose, an aperture 31 is attached to one of the outer leaves 21 of the connection tab 29, so that the openings 10, 11, 12 are bounded by a respective substantially rectangular cutout 32. The bolt 30 is disposed in the target opening 12, wherein the connection tabs 29, 29 a in Fig. 5 in the initial angular position and in Fig. 6 are shown in the 40 ° -Winkelstellung.

Der Anschlag 33 ist bei dieser Ausführungsform durch abgerundete, konkave Anlageflächen 34 gebildet, die an dem ersten Schenkel 17 der Verbindungs-Lasche 29a vorgesehen sind.The stop 33 is formed in this embodiment by rounded, concave bearing surfaces 34 which are provided on the first leg 17 of the connecting lug 29 a.

Es ist weiterhin denkbar, Verbindungs-Laschen zu verwenden, wobei jeweils die Winkelanordnung der Schenkel zueinander veränderlich ausgebildet ist, beispielsweise indem an dem Scheitelpunkt ein Schwenkgelenk vorgesehen ist. Darüber hinaus könnten die schwenkbar miteinander verbundenen Schenkel einer Verbindungs-Lasche weitere Ziel-Öffnungen aufweisen, die bei einer veränderten Winkelanordnung der Schenkel in der Ausgangs-Winkelstellung des Auslegersystems paarweise miteinander fluchten, so dass weitere Ziel-Winkelstellungen der Verbindungs-Elemente mit nur einer Verbindungs-Lasche ermöglicht werden. Es ist auch möglich, Verbindungs-Laschen einzusetzen, deren Winkelanordnungen zwischen den Schenkeln sich unterscheiden. Mit diesen Maßnahmen können die zentrischen Abstände A1 bis A3 zwischen den fluchtenden Öffnungen derart beeinflusst werden, dass verschiedene Winkelstellungen einstellbar sind.It is also conceivable to use connection tabs, wherein in each case the angular arrangement of the legs is mutually variable, for example by a pivot joint is provided at the apex. In addition, the pivotally interconnected legs of a connecting tab could have further target openings, which are aligned with each other in a changed angular arrangement of the legs in the output angular position of the boom system with each other, so that further target angular positions of the connecting elements with only one connection -Lasche be enabled. It is also possible to use connection tabs whose angular arrangements differ between the legs. With these measures, the central distances A1 to A3 between the aligned openings can be influenced in such a way that different angular positions can be set.
