Description

Die Erfindung betrifft den An- und Abbau einer Zusatzeinrichtung an den Hauptausleger eines Mobilkranes, der ohne den Einsatz eines Hilfskrans erfolgen soll. Es ist bekannt, bei Mobilkranen, insbesondere Teleskopkranen, an den Kopf des Hauptauslegers des Grundkrans eine Zusatzeinrichtung anzubauen.The invention relates to the attachment and removal of an attachment to the main boom of a mobile crane, which should be done without the use of an auxiliary crane. It is known to grow in mobile cranes, especially telescopic cranes, to the head of the main boom of the basic crane an additional device.

Diese vorübergehend oder ständig verbleibende Einrichtung wird benutzt, um eine über die größte Auslegerlänge des Teleskopkrans hinausgehende noch größere Auslegerlänge zu erzielen.This temporarily or permanently remaining device is used to achieve an even greater boom length beyond the largest boom length of the telescopic crane.

Die Einrichtungen sind grundsätzlich als Baukastensysteme aufgebaut und können je nach Erfordernis an Länge bzw. Tragkraft zusammengestellt werden.The facilities are basically constructed as modular systems and can be assembled according to the requirements of length or load capacity.

Die einzelnen Hauptelemente der Einrichtung bestehen in idealer Weise aus einer Fachwerk-Rohr-Konstruktlon in transportfähigen Abmessungen. Die Einrichtungselemente werden mit Bolzen an den entsprechenden Punkten zu einer Einheit zusammengefügt.The individual main elements of the device are ideally made of a truss-Rohrkonstruktlon in transportable dimensions. The furnishing elements are assembled with bolts at the corresponding points to form a unit.

Die zusätzliche Einrichtung wird in den meisten Fällen nicht mit dem Grundkran mitgeführt und muss separat transportiert werden.The additional equipment is not carried along with the basic crane in most cases and has to be transported separately.

Speziell dafür vorgesehene Einrichtungen können aber auch mit dem Grundkran mitgeführt werden, wenn es die Gewichts- und Platzverhältnisse erlauben.But specially designed facilities can also be carried along with the base crane, if it allows the weight and space.

Der Anbau an den Hauptauslegerkopf kann Stück für Stück oder als vormontierte Einheit erfolgen.The attachment to the main boom head can be done piece by piece or as a preassembled unit.

Diese Arbeit wird bekanntermaßen mit einem zusätzlichen Hilfskran bewältigt.This work is known to be accomplished with an additional auxiliary crane.

Die Bereitstellung eines Hilfskranes verursacht zusätzliche Kosten, da dieser mit zusätzlichem Personal an die Aufrüststelle herangeführt werden muss. Außerdem ist es schwierig, die frei schwebend angehobene Zusatzeinrichtung unter Beachtung der Verletzungsgefahr für die Monteure punktgenau an die am Auslegerkopf vorgesehenen Befestigungspunkte heranzuführen. Das bedeutet einen relativ hohen Zeitaufwand für die Montage.The provision of an auxiliary crane causes additional costs, as it must be brought to the upgrade with additional staff. In addition, it is difficult to precisely introduce the freely levitated additional device, taking into account the risk of injury to the fitters to the provided on the boom head mounting points. This means a relatively high amount of time for assembly.

Der Erfindung lag deshalb die Aufgabe zugrunde, den Anbau der Zusatzeinrichtung zu vereinfachen und sicherer zu machen, insbesondere diesen ohne Einsatz eines zusätzlichen Hilfskrans auszuführen.The invention therefore an object of the invention to simplify the cultivation of the attachment and make it safer, in particular to perform this without the use of an additional auxiliary crane.

Die Lösung der Aufgabe erfolgt entsprechend den Merkmalen der selbständigen Ansprüche 1, 8 und 10. Die weiteren Ansprüche stellen zweckmäßige Ausgestaltungen der erfinderischen Lösung dar.The object is achieved according to the features of the independent claims 1, 8 and 10. The other claims represent expedient embodiments the inventive solution.

Erfindungsgemäß wird die vormontierte Zusatzeinrichtung, die idealerweise aus einer Fachwerk-Rohr-Konstruktlon in transportfähigen Abmessungen besteht, fluchtend zum Hauptausleger des Mobilkrans auf den Boden abgelegt.According to the invention, the preassembled additional device, which ideally consists of a truss-tube construction in transportable dimensions, is placed in alignment with the main boom of the mobile crane on the ground.

Sodann wird ein Teilstück an dem dem Mobilkran zugewandten Ende der Zusatzeinrichtung um einen oberen Drehpunkt drehend in eine Schrägstellung angehoben und in dieser Lage gehalten.Then, a portion is lifted at the end facing the mobile crane end of the attachment to an upper pivot point rotating in an inclined position and held in this position.

Danach wird der Kopf des Hauptauslegers mit dem unteren Ende des in Schrägstellung befindlichen Endes des dem Mobilkran zugewandten Teilstücks der Zusatzeinrichtung drehbar verbolzt und die Zusatzeinrichtung mittels eines am dem Mobilkran abgewandten Ende des in Schrägstellung angehobenen Teilstücks befestigten und über eine Rolle geführten Hubseils in eine waagerechte Position gezogen, so dass das Teilstück der Zusatzeinrichtung, die übrigen Teile der Zusatzeinrichtung und der Hauptausleger des Mobilkrans fluchtend hintereinander ausgerichtet sind.Thereafter, the head of the main boom is rotatably bolted to the lower end of the inclined end of the mobile crane facing portion of the attachment and the additional device by means of a remote from the mobile crane end of the raised portion in oblique position and guided over a roller hoist rope in a horizontal position pulled, so that the portion of the attachment, the remaining parts of the attachment and the main boom of the mobile crane are aligned in a row.

Abschließend werden die genannten Bauelemente untereinander und am Kopf des Hauptauslegers durch Verbolzen mit diesem verbunden.Finally, the said components are connected to each other and at the head of the main boom by bolting with this.

Wenn sich der Hauptausleger nicht so weit nach unten abwinkeln bzw. der gesamte Kran nicht so weit schräg stellen lässt, dass die Spitze der Zusatzeinrichtung im fertig angebauten Zustand der Einrichtung mit einem an der Spitze angeordneten Laufrad auf den Boden aufsteht, kann zur Erleichterung der Montage die Zusatzeinrichtung vor dem Anheben des dem Mobilkran zugewandten Endes der Zusatzeinrichtung an dem dem Mobilkran abgewandten Ende angehoben werden, so dass ein um einen unteren Drehpunkt drehbares Teilstück der Zusatzeinrichtung eine Schrägstellung nach unten einnimmt, in dieser Lage gehalten wird, wobei das Ende des Teilstücks Bodenberührung behält.If the main boom does not bend so far down or the entire crane is not tilted so far that the tip of the attachment stands in the ready-mounted state of the device with a tip wheel arranged on the ground, for ease of assembly the accessory is lifted before lifting the mobile crane facing the end of the attachment at the end facing away from the mobile crane, so that a rotatable about a lower pivot portion of the attachment occupies a downward inclination, is held in this position, the end of the section ground contact reserves.

Die Schrägstellung des am dem Mobilkran abgewandten Ende befindlichen Teilstücks der Zusatzeinrichtung wird nach dem Anheben des dem Mobilkran zugewandten Endes der Zusatzeinrichtung durch den Zug eines am Kopf der Zusatzeinrichtung befestigten Hubseils aufgehoben, so dass die Teilstücke der Zusatzeinrichtung, die übrigen Teile der Zusatzeinrichtung und der Hauptausleger des Mobilkrans fluchtend hintereinander ausgerichtet sind. Abschließend werden die genannten Bauelemente untereinander und am Kopf des Hauptauslegers durch Verbolzen mit diesem verbunden.The inclination of the remote from the mobile crane end portion of the attachment is lifted after lifting the end of the mobile crane end of the attachment by the train of a mounted on the head of the attachment hoist such that the portions of the attachment, the remaining parts of the attachment and the main boom of the mobile crane are aligned in alignment one behind the other. Finally, the said components are connected to each other and at the head of the main boom by bolting with this.

Mit Hilfe des Mobilkrans 1 wurde die Zusatzeinrichtung 2 aus mehreren Einzelelementen 2.1 bis 2.7 in der gewünschten Konfiguration zusammengebaut und fluchtend zum Hauptausleger 1.1 des Mobilkrans 1, in der Draufsicht gesehen, auf den Boden abgelegt. Hierbei wird das dem Mobilkran 1 zugewandte Ende der Zusatzeinrichtung 2, wie in Fig. 1 dargestellt, mit dem Einzelelement 2.2 auf die Verschiebevorrichtung 4 aufgelegt und durch Verschieben zum Hauptausleger ausgerichtet.With the help of the mobile crane 1, the additional device 2 was assembled from several individual elements 2.1 to 2.7 in the desired configuration and placed in alignment with the main boom 1.1 of the mobile crane 1, seen in plan view, on the ground. Here, the mobile crane 1 facing the end of the attachment 2, as in Fig. 1 represented with the single element 2.2 placed on the displacement device 4 and aligned by moving to the main boom.

Das Teilstück 2.1 der Zusatzeinrichtung (Kopfanschluss) wird dann mit dem Kran 1 angehoben (Fig. 2), dadurch um Punkt C (Fig. 7) nach oben gedreht und zwischen den Punkten D1 und D2 zur Fixierung der Schräglage des Teilstücks 2.1 eine Distanzstange 5 eingebracht.The section 2.1 of the additional device (head connection) is then lifted by the crane 1 ( Fig. 2 ), by point C ( Fig. 7 ) Upwards and introduced between the points D1 and D2 for fixing the inclined position of the section 2.1, a spacer rod 5.

Sodann wird das dem Mobilkran abgewandte Teilstück 2.7 (Spitze) durch Anheben der Zusatzeinrichtung 2 um den Punkt E nach unten in eine Schrägstellung gedreht und zur Fixierung der Schrägstellung eine Distanzstange 6 (Fig. 8) zwischen den Punkten F1 und F2 eingefügt. Die abgewinkelte Stellung der Spitze der Zusatzeinrichtung 2 ist nötig, um die horizontale Flucht zum Hauptausleger 1.1 des Mobilkrans 1 herzustellen, um später in Punkt B (Fig. 7) zu verbolzen.Then the remote from the mobile crane section 2.7 (top) is rotated by lifting the attachment 2 to the point E down to an inclined position and to fix the inclination a spacer rod 6 (top) Fig. 8 ) between points F1 and F2. The angled position of the tip of the attachment 2 is necessary to establish the horizontal flight to the main boom 1.1 of the mobile crane 1, to be described later in point B ( Fig. 7 ) to bolt.

Sodann wird der Hauptauslegerkopf 1.2 an das schräg gestellte Teilstück 2.1 herangeführt und mit diesem im Punkt A verbolzt. Dabei wird das Ausrichten der Teile zueinander bzw. die Flucht der Bohrungen in Punkt A durch Bewegen des Hauptauslegers 1.1 und durch Verschieben der Einrichtung 2 mittels der Verschiebevorrichtung 4 (Figuren 10 und 11) ermöglicht.Then the main boom head 1.2 is brought to the inclined section 2.1 and bolted with this point A. In this case, the alignment of the parts to each other or the alignment of the holes in point A by moving the main boom 1.1 and by moving the device 2 by means of the displacement device 4 (FIG. FIGS. 10 and 11 ).

Nach dem Verbolzen in Punkt A kann die Distanzstange 5 entfernt werden.After bolting in point A, the spacer rod 5 can be removed.

Nun wird das Hubseil 7 des Krans über die Rolle 2.8 (Figuren 3 und 7) geführt und in Punkt G befestigt.Now, the hoist rope 7 of the crane on the role of 2.8 ( Figures 3 and 7 ) and fixed in point G.

Durch Einfahren des Hubseils 7 schamiert das Teilstück 2.1 in den Punkten A und C und dreht sich so weit nach oben, bis Punkt B1 am Kopf des Hauptauslegers mit Punkt B2 des Teilstücks 2.1 verbolzt werden kann. Im angehobenen Zustand der Einrichtung kann auch Punkt D1 am Einrichtungselement 2.2 mit Punkt D2 am Teilstück 2.1 verbunden werden. Es entsteht der in Fig. 4 dargestellte Zustand.By retracting the hoist rope 7, the section 2.1 in the points A and C embarrassed and turns so far up until point B1 can be bolted to the head of the main boom with point B2 of the section 2.1. In the raised state of the device, point D1 on the device element 2.2 can also be connected to point D2 on the section 2.1. The result is the in Fig. 4 illustrated state.

Um das Entfernen der Distanzstange 6 zu ermöglichen, wird der Hauptausleger 1.1 mit der davor befindlichen Zusatzeinrichtung 2 aufgewippt, bis sich das Laufrad 2.9 kurz vor dem Abheben vom Boden befindet. Die Bolzenverbindung in den Punkten F1 undIn order to allow the removal of the spacer rod 6, the main boom 1.1 is flipped up with the auxiliary device 2 in front, until the impeller 2.9 is just before lifting off the ground. The bolt connection in points F1 and

F2 wird dadurch entlastet, kann gelöst und die Distanzstange 6 entbolzt und entfernt werden.F2 is thereby relieved, can be solved and the spacer rod 6 is unbolt and removed.

Das Hubseil 7 wird nunmehr über die Rolle 2.10 im Punkt H festgemacht (Figuren 4 und 9).The hoist rope 7 is now moored over the roller 2.10 at point H ( FIGS. 4 and 9 ).

Durch das Einfahren des Hubseils wird das Teilstück 2.7 der Zusatzeinrichtung 2 um den Punkt E (Fig. 8) gedreht und hebt dabei vom Boden ab, bis die Punkte F1 und F2 miteinander verbolzt werden können.Due to the retraction of the hoist rope, the section 2.7 of the auxiliary device 2 is about the point E ( Fig. 8 ) and lifts it off the ground until the points F1 and F2 can be bolted together.

Nach dem Verbolzen wird das Hubseil von Punkt H gelöst.After bolting, the hoist rope is released from point H.

Der Anbau der Zusatzeinrichtung 2 an den Hauptausleger 1.1 des Mobilkrans 1 ist damit beendet.The cultivation of the attachment 2 to the main boom 1.1 of the mobile crane 1 is thus completed.

Der Abbau der Zusatzeinrichtung geschieht in umgekehrter Reihenfolge.The dismantling of the attachment is done in reverse order.

Das Schrägstellen der Teilstücke 2.1 und 2.7 der Zusatzeinrichtung 2 könnte auch anstatt durch Hubseilanhebung durch Zylinder oder eine ähnlichen Vorrichtung herbeigeführt werden.The skewing of the sections 2.1 and 2.7 of the attachment 2 could also be brought about instead by lifting cable lift by cylinder or similar device.

Das Anheben der Zusatzeinrichtung und die fixierte Schrägstellung des Teilstücks 2.7 kann entfalten, wenn sich der Hauptausleger 1.1 so weit nach unten abwinkeln (Unterflurstellung siehe Fig. 6) bzw. der gesamte Kran schräg stellen lässt, dass die Spitze der Einrichtung 2 im fertig angebauten Zustand der Einrichtung mit dem Laufrad 2.9 auf den Boden kommen würde.The raising of the attachment and the fixed inclination of the section 2.7 can unfold when the main boom 1.1 so far down angled (underfloor position, see Fig. 6 ) or tilt the entire crane that the top of the device 2 would come in the ready-mounted state of the device with the impeller 2.9 on the floor.

Das Ausführungsbeispiel der Verschiebevorrichtung 4 ist in den Figuren 10 und 11 dargestellt.The embodiment of the displacement device 4 is in the FIGS. 10 and 11 shown.
