Abstract
Description
Die Erfindung betrifft ein Verfahren zur Montage eines Mobilkrans, insbesondere eines Teleskopkrans, auf einer Baustelle, mit einem Hauptausleger sowie mit wenigstens einer Auslegererweiterung.The invention relates to a method for mounting a mobile crane, in particular a telescopic crane, on a construction site, with a main boom and with at least one boom extension.
Große Teleskopkrane verwenden während des Kraneinsatzes häufig Gitterstücke als Hauptauslegerverlängerung. Ebenso werden regelmäßig Gitterstücke zu einem wippbaren oder feststehenden Spitzenausleger zusammengesetzt und am teleskopierbaren Hauptausleger des Teleskopkrans montiert.Large telescopic cranes often use lattice pieces as main boom extension during crane use. Likewise, lattice pieces are regularly assembled into a tiltable or fixed luffing jib and mounted on the telescopic main boom of the telescopic crane.
Aufgrund der reglementierten zulässigen Fahrzeugabmessung des Mobilkrans im Straßenverkehr werden die einzelnen Gitterstücke separat zum Einsatzort transportiert und erst nach dem Eintreffen an der Baustelle am Kranausleger montiert. Für die Montage der einzelnen Gitterelemente auf der Baustelle sind jedoch Hilfsgeräte, wie beispielsweise ein Hilfskran zwingend erforderlich. Eine optimale Ausnutzung des Transportvolumens der Gitterstücke wird üblich durch geeignete Transportsysteme gewährleistet, die den gemeinsamen Transport der schweren Ballaststücke mit den einzelnen Gitterstücken erlauben.Due to the regimented permissible vehicle dimensions of the mobile crane in road traffic, the individual lattice pieces are transported separately to the site and mounted on the crane boom after arrival at the site. For the installation of the individual grid elements on the site, however, auxiliary equipment, such as an auxiliary crane are absolutely necessary. An optimal utilization of the transport volume of the lattice pieces is usually ensured by suitable transport systems that allow the common transport of heavy ballast pieces with the individual lattice pieces.
Der Transport eines Hilfskrans zum Einsatzort schlägt stets mit erheblichen Kosten zu Buche, da dieser nur schlecht oder gar nicht für anderweitige Kranarbeiten auf der Baustelle nutzbar ist. Ferner kann ein Einsatz des Hilfskrans in manchen Fällen aufgrund der Platzverhältnisse auf der Baustelle ausgeschlossen sein.The transport of an auxiliary crane to the site always beats at considerable cost to book, because this is poor or not at all for other crane work on the site is available. Furthermore, use of the auxiliary crane may in some cases be ruled out due to the space available on the construction site.
Die Aufgabe der vorliegenden Erfindung besteht nun darin, ein Verfahren zur Montage eines Krans am Einsatzort aufzuzeigen, das nicht nur kostengünstiger, sondern gleichfalls einfacher und weniger zeitaufwendig ist.The object of the present invention is now to show a method for assembling a crane at the site, which is not only less expensive, but also easier and less time consuming.
Die gestellte Aufgabe wird durch ein Verfahren zur Montage eines Mobilkrans gelöst, das die Merkmale des Anspruchs 1 aufweist. Das Verfahren betrifft im Einzelnen die Montage einer aus wenigstens einem Gitterstück bestehenden Auslegererweiterung am Hauptausleger des Mobilkrans, der insbesondere als mobiler Teleskopkran ausgeführt ist.The object is achieved by a method for assembling a mobile crane having the features of
Das erfindungsgemäße Verfahren schlägt also vor, den Hauptausleger und wenigstens ein Gitterstück der Auslegererweiterung durch Verfahren des Transportmittels bzw. des Mobilkrans grob auszurichten und in die Montageposition zu bringen. Im Anschluß werden der Hauptausleger und das Gitterstück über ein oder mehrere Zugmittel miteinander verbunden. Das oder die Zugmittel werden sodann durch das Aufwippen des Hauptauslegers mit einem gewissen Zug beaufschlagt. Vorteilhafterweise hebt hierdurch die zu montierende Auslegererweiterung von der Ladefläche des Transportmittels ab und die Achsen der Verbindungsstellen des Gitterstückes bzw. der Auslegererweiterung werden ebenfalls horizontal ausgerichtet. Demnach sind die Achsen der Verbindungsstellen des Hauptauslegers sowie die der Auslegererweiterung zumindest teilweise parallel zueinander und horizontal ausgerichtet, was die Paarung, insbesondere die Verbolzung der Verbindungsstellen erlaubt. Das Aufwippen des Hauptauslegers erfolgt beispielsweise über den Wippantrieb, insbesondere über den Wippzylinder.The method according to the invention therefore proposes roughly aligning the main boom and at least one lattice piece of the boom extension by moving the means of transport or the mobile crane and bringing it into the assembly position. Following the main boom and the lattice piece via one or more traction means are interconnected. The one or more traction means are then acted upon by the teetering of the main boom with a certain train. Advantageously, thereby lifts the boom extension to be mounted from the bed of the transport and the axes of the connection points of the lattice piece or the boom extension are also aligned horizontally. Accordingly, the axes of the joints of the main boom and the boom extension are at least partially parallel to each other and aligned horizontally, which allows the pairing, in particular the bolting of the joints. The rocking of the main boom takes place for example via the rocker drive, in particular via the luffing cylinder.
Wenigstens eine Auslegererweiterung kann eine Hauptauslegerverlängerung oder ein wippbarer bzw. fester Spitzenausleger sein. Die Auslegererweiterung kann bevorzugt aus mehreren Gitterstücken bestehen, die sukzessive am Hauptausleger montiert werden.At least one boom extension may be a main boom extension or a luffing jib. The boom extension may preferably consist of several lattice pieces, which are successively mounted on the main boom.
Eine maßgebliche Zeitersparnis bei der Kranmontage kann erzielt werden, wenn die Gitterstücke nicht einzeln zur Baustelle verfahren werden, sondern diese bereits vor dem Transport durch Vormontage zu wenigstens einer Auslegererweiterung zusammengefügt werden. Demnach werden die Auslegererweiterungen einsatzbereit vormontiert, d.h. diese werden bevorzugt vorab in einen großteils arbeitsfähigen Zustand versetzt. Das erfindungsgemäße Verfahren muss demnach zur Montage einer Auslegererweiterung nur einmalig zur Befestigung des endseitigen Gitterstückes der aus mehreren Gitterstücken vormontierten Auslegererweiterung ausgeführt werden.Significant time savings in crane installation can be achieved if the grid pieces are not moved individually to the site, but they are already assembled before transport by pre-assembly to at least one boom extension. Accordingly, the jib extensions are pre-assembled ready for use, i. These are preferably pre-set in a largely workable state. The inventive method must therefore be performed only once for mounting a boom extension for attaching the end-side lattice piece of pre-assembled from several pieces of lattice extension for mounting a boom extension.
Mindestens eine vormontierte Auslegererweiterung wird separat zum Mobilkran mit Hilfe eines Transportmittels zur Einsatzstelle transportiert. Das Transportmittel für die wenigstens eine Auslegererweiterung ist vorzugsweise ein Sattelanhänger oder ein Tieflader.At least one preassembled jib extension is transported separately to the mobile crane by means of a means of transport to the place of use. The transport for the at least one jib extension is preferably a semi-trailer or a low loader.
Ein oder mehreren vormontierte Auslegererweiterungen werden bevorzugt durch eine geeignete Vorrichtung des Transportmittels in einer für den Transport und für die nachfolgende Montage am Mobilkran geeigneten Position auf dem Transportmittel gehalten.One or more preassembled jib extensions are preferably held by a suitable device of the transport in a suitable position for transport and for subsequent mounting on the mobile crane position on the transport.
Beispielsweise wird bei der Einsatzplanung für den Mobilkran die benötigte Auslegererweiterung bestimmt. Die entsprechende Auslegerkombination wird in einzelne Auslegererweiterungen zerlegt, die mit Hilfe des Transportfahrzeuges an den Einsatzort verfahren werden. Die entsprechende Auslegerkombination wird dann durch die sukzessive Montage der einzelnen Auslegererweiterungen am Mobilkran erreicht. Selbstverständlich kann die vollständige Auslegerkombination bereits vormontiert zur Baustelle transportiert werden und im Ganzen durch einen einzigen Montagevorgang am Mobilkran montiert werden.For example, in the mission planning for the mobile crane, the boom extension required is determined. The corresponding boom combination is broken down into individual jib extensions, which are moved with the help of the transport vehicle to the site. The corresponding boom combination is then achieved by the successive assembly of the individual boom extensions on the mobile crane. Of course, the complete boom combination can be pre-assembled be transported to the site and be mounted as a whole by a single assembly operation on the mobile crane.
Das erfindungsgemäße Verfahren eröffnet eine Möglichkeit für einen Mobilkran zur selbstständigen Montage wenigstens eines Gitterstückes bzw. einer Auslegererweiterung an seinem Hauptausleger. Ein kostenintensiver Hilfskran wird demnach nicht mehr benötigt. Die Selbstmontage der Auslegererweiterung wird durch den erfindungsgemäßen Einsatz der Zugmittel ermöglicht. Der Mobilkran ist für die Selbstmontage bereits mit seinem notwendigen Ballast sowie seinem Hauptausleger verbunden.The inventive method opens up a possibility for a mobile crane for the independent assembly of at least one lattice piece or a boom extension on its main boom. A costly auxiliary crane is therefore no longer needed. The self-assembly of the boom extension is made possible by the use of the traction device according to the invention. The mobile crane is already connected for its self-assembly with its necessary ballast and its main boom.
Zur Selbstmontage des Gitterstückes bzw. der Auslegererweiterung, d.h. zur Anbringung der Zugmittel, wird der Mobilkran in die Montageposition gebracht. Vorteilhafterweise wird der Hauptausleger des Mobilkrans mit Hilfe des Wippzylinders in eine etwa horizontale Lage abgewippt, um die Verbindungsstellen des Hauptauslegers in den Bereich der Verbindungsstellen des auf dem Transportmittel gelagerten Gitterstückes bzw. der Auslegererweiterung zu bringen und um die Verbindung mit Hilfe ein oder mehrerer Zugmittel herstellen zu können.For self-assembly of the lattice piece or boom extension, i. for attaching the traction means, the mobile crane is brought into the mounting position. Advantageously, the main boom of the mobile crane is tapped using the rocker cylinder in an approximately horizontal position to bring the joints of the main boom in the region of the joints of the mounted on the transport lattice piece or the boom extension and make the connection by means of one or more traction means to be able to.
Insbesondere wird der Teleskopierzylinder des Hauptauslegers hierzu maximal zulässig auf Block gefahren, um die optimale Montageposition für die Verbindungsherstellung zwischen Gitterstück/Auslegererweiterung und Hauptausleger zu erreichen. Möglich ist hier eine kopfseitige Neigung des Hauptauslegers um ca. 1° oder mehr gegenüber der Horizontalen. Die Neigung bewirkt, dass die kopfseitig angeordneten Verbindungsstellen des Hauptauslegers unterhalb der Verbindungsstellen der Auslegererweiterung liegen, was den nachfolgenden Verbindungsprozess vereinfacht.In particular, the telescoping cylinder of the main boom is this maximum allowed to run on block to achieve the optimum mounting position for the connection between the lattice piece / boom extension and main boom. Possible here is a head-side inclination of the main boom by about 1 ° or more relative to the horizontal. The inclination causes the headboard joints of the main boom to be below the jib extension junctions, which simplifies the subsequent connection process.
Aufgrund der technischen Gegebenheiten bekannter Wippantriebe ist eine Neigung der Längsachse des Hauptauslegers auf ca. 1° bis maximal 2° unter die Horizontale begrenzt. Sollte der mögliche Neigungswinkel des Wippantriebs für den Montageprozess unzureichend sein, so kann in einer bevorzugten Ausgestaltung die Neigung des Hauptauslegers durch Verstellen der einstellbaren Achsfederung und/oder der Kranabstützung des Mobilkrans erhöht werden. Hierdurch lässt sich eine zusätzliche kopfseitige Neigung der Hauptauslegerlängsachse gegenüber der Horizontalen von etwa 1° oder mehr erreichen.Due to the technical characteristics of known rocker drives, an inclination of the longitudinal axis of the main boom is limited to approximately 1 ° to a maximum of 2 ° below the horizontal. If the possible angle of inclination of the rocker drive for the assembly process is insufficient, so in a preferred embodiment, the inclination of the main boom can be increased by adjusting the adjustable axle suspension and / or crane support of the mobile crane. As a result, an additional head-side inclination of the main boom longitudinal axis relative to the horizontal of about 1 ° or more can be achieved.
In einer vorteilhaften Ausführung des erfindungsgemäßen Verfahrens wird hierbei zunächst die einstellbare Achsfederung nahezu vollständig abgelassen, wodurch eine insgesamt sehr niedrige und daher leicht zugängliche Arbeitshöhe für den nachfolgenden Verbindungsprozess zwischen Auslegererweiterung und Hauptausleger ermöglicht wird. Die kranbedingt notwendige Neigung der Hauptauslegerlängsachse wird im Anschluß über die Kranabstützung eingestellt. Zweckmäßig sind eine zur Horizontalen geneigte Ausrichtung der Hauptauslegerlängsachse sowie eine horizontal ausgerichtete Hauptauslegerquerachse.In an advantageous embodiment of the method according to the invention, in this case the adjustable axle suspension is first of all almost completely drained off, whereby an overall very low and therefore easily accessible working height is made possible for the subsequent connection process between boom extension and main boom. The crankshaft necessary inclination of the main boom longitudinal axis is set in the connection via the crane support. Appropriately, an inclined to the horizontal orientation of the main boom longitudinal axis and a horizontally oriented main boom transverse axis.
Optional können die Längsachsen von Hauptausleger und Gitterstück/Auslegererweiterung durch Drehen des Kranoberwagens auf eine gemeinsame vertikale Ebene gelegt werden.Optionally, the longitudinal axes of main boom and lattice / boom extension can be laid by turning the crane truck onto a common vertical plane.
Ferner ist es vorteilhaft, wenn die Längsachsen von Hauptausleger und Gitterstück durch Verfahren des Transportmittels und/oder des Mobilkrans zueinander fluchtend ausgerichtet werden. Durch Teleskopieren des Hauptauslegers bzw. Verfahren des Transportmittels und/oder Mobilkrans wird dann eine Überdeckung der Verbindungsstellen von Hauptausleger und Gitterstück erzielt. In diesem Fall bewegen sich die oberen Enden der gespannten Zugmittel auf Kreisbahnen. Im Anschluß können die Verbindungsmittel, insbesondere Verbindungsbolzen, gesteckt werden.Further, it is advantageous if the longitudinal axes of main boom and lattice piece are aligned by moving the transport means and / or the mobile crane to each other. By telescoping the main boom or method of transport and / or mobile crane then a coverage of the joints of main boom and lattice piece is achieved. In this case, the upper ends of the tensioned traction means move on circular paths. Following the connection means, in particular connecting bolts, can be plugged.
Die Länge der Zugmittel ist speziell auf die Gitterstückgeometrie angepaßt. Vorteilhafterweise wird die Längung des oder der Zugmittel vor dem Aufwippvorgang entsprechend angepaßt, um eine optimale Ausrichtung der Verbindungsachsen zu gewährleisten.The length of the traction means is specially adapted to the lattice geometry. Advantageously, the elongation of the traction means or before the Aufwippvorgang is adjusted accordingly to ensure optimum alignment of the connecting axes.
Weiterhin verläuft die Verbindungslinie wenigstens eines Zugmittels bevorzugt von dem in horizontaler Lage oben liegenden Hauptauslegerbereich zum unten liegenden Bereich der Auslegererweiterung. Die Anlenkpunkte der Zugmittel an der Auslegererweiterung bzw. dem Hauptausleger liegen in der Nähe der jeweiligen Verbindungsstellen bzw. Verbolzstellen, deren Zugang allerdings nicht durch die Zugmittel beeinträchtigt wird.Furthermore, the connecting line of at least one traction means preferably extends from the main boom area located at the top in the horizontal position to the lower area of the boom widening. The articulation points of the traction means on the boom extension or the main boom are in the vicinity of the respective connection points or Verbolzstellen whose access is not affected by the traction means.
Durch die Wiederholung des Verfahrens kann vorteilhafterweise eine bereits am Hauptausleger montierte Auslegererweiterung mit wenigstens einer weiteren Auslegererweiterung montiert werden. Die voranstehende Beschreibung bezieht sich in diesem Fall auf die Verbindungsstellen der bereits am Hauptausleger montierten Auslegererweiterung sowie auf die Verbindungsstellen der zu montierenden Auslegererweiterung, die auf der Ladefläche des Transportmittels gelagert ist.By repeating the method, it is advantageously possible to mount a jib extension already mounted on the main jib with at least one further jib extension. The above description refers in this case to the joints of the boom extension already mounted on the main boom and to the joints of the boom extension to be mounted, which is mounted on the bed of the means of transport.
Die Demontage des Mobilkrans erfolgt zweckmäßig durch Umkehrung der Ausführungsabfolge der Verfahrensschritte.The dismantling of the mobile crane is expediently carried out by reversing the execution sequence of the method steps.
Die Erfindung ist weiterhin auf einen Mobilkran mit einem Hauptausleger sowie mit mindestens einer aus wenigstens einem Gitterstück bestehenden Auslegererweiterung gerichtet. Insbesondere betrifft die Erfindung einen Mobilkran mit Teleskopausleger. Erfindungsgemäß ist der Mobilkran mit entsprechenden Mitteln zur Durchführung des erfindungsgemäßen Verfahrens ausgeführt. Der Mobilkran weist folglich dieselben Vorteile und Einzelheiten wie die voranstehend beschriebenen vorteilhaften Ausführungen des erfindungsgemäßen Verfahrens auf, weshalb an dieser Stelle auf eine erneute Erläuterung verzichtet wird.The invention is further directed to a mobile crane with a main boom and with at least one boom extension consisting of at least one lattice piece. In particular, the invention relates to a mobile crane with telescopic boom. According to the invention, the mobile crane is designed with appropriate means for carrying out the method according to the invention. The mobile crane thus has the same advantages and details as the above-described advantageous embodiments of the method according to the invention, which is why a further explanation is omitted here.
Eine mögliche Ausführung des Mobilkrans sieht vor, dass wenigstens ein Zugmittel ein Seil oder eine Kette oder eine Klappstange ist. Ebenfalls ist die Kombination der vorgeschlagenen Elemente zu einem Zugmittel denkbar. Denkbar ist es auch, dass einzelne Elemente hintereinander und/oder parallel zueinander zu einem Zugmittel miteinander verknüpft sind. Ein Zugmittel kann demnach über einen oder mehrere Anlenkpunkte mit dem Hauptausleger und/oder der Auslegererweiterung in Verbindung stehen.A possible embodiment of the mobile crane provides that at least one traction means is a rope or a chain or a folding rod. Likewise, the combination of the proposed elements to a traction means is conceivable. It is also conceivable that individual elements are connected one behind the other and / or parallel to each other to form a traction means. A traction device can therefore have one or more Link points with the main boom and / or the boom extension in conjunction.
Vorzugsweise ist wenigstens ein Zugmittel längenverstellbar ausgeführt, um eine optimale Anpassung an die verwendete Gitterstückgeometrie der Auslegererweiterung sowie des Hauptauslegers des Mobilkrans zu gewährleisten.Preferably, at least one traction means is designed to be adjustable in length in order to ensure optimum adaptation to the grid geometry used of the boom extension and the main boom of the mobile crane.
Wenigstens eine Auslegererweiterung ist eine Hauptauslegerverlängerung bzw. ein wippbarer oder fester Spitzenausleger. Möglich ist auch eine Auslegerkombination aus den aufgezählten Auslegererweiterungen.At least one boom extension is a main boom extension. Also possible is a boom combination of the listed boom extensions.

Im nachfolgenden Teil der Beschreibung wird ein konkretes Ausführungsbeispiel des erfindungsgemäßen Verfahrens zur Montage eines Teleskopkrans sowie ein Ausführungsbeispiel des Teleskopkrans anhand der
Bei der Kraneinsatzplanung wird die benötigte Auslegerkombination für einen teleskopierbaren Mobilkran festgelegt. Zur Erweiterung des Kranhauptauslegers sollen ein oder mehrere Auslegererweiterungen an der Hauptauslegerspitze montiert werden, um den Kran für die geplante Kranarbeit zu rüsten. Die entsprechenden Auslegererweiterungen bestehen aus einzelnen Gitterstücken 1, 1 a, 1b, 1 c, 1', 1 a', 1b', 1c', die bereits vor dem Transport zur Einsatzstelle miteinander kombiniert und in einen größtenteils arbeitsfähigen Zustand versetzt wurden. Mögliche vormontierte Auslegererweiterungen sind zum Beispiel eine Hauptauslegerverlängerung oder auch ein fester bzw. wippbarer Spitzenausleger.In crane application planning, the required boom combination for a telescopic mobile crane is specified. To extend the crane boom, one or more jib extensions are to be mounted on the main jib tip to equip the crane for the planned crane work. The corresponding jib extensions consist of
Die in einzelne Auslegererweiterungen 2, 2' zerlegte vollständige Auslegerkombination wird in der Zentrale von einem dort vorhandenen Kran auf das in
Der Mobilkran 6, der sich selbstständig zur Baustelle bewegt, ist bereits mit dem einsatzbereiten Hauptausleger 5 sowie dem für die Kranarbeit benötigten Ballast 7 verbunden. Zur Montage der Auslegererweiterung 2, 2' wird der Kran 6 in die passende Montageposition gebracht. Hierzu wird der Hauptausleger 5, wie in
Für die Paarung der entsprechenden Verbolzstellen ist es erforderlich, dass die Verbolzstellen des Hauptauslegers 5 in der Montageposition geringfügig unterhalb der Verbolzstellen der zu montierenden Auslegerverlängerung 2 liegen. Diese Voraussetzung erfordert eine Schrägstellung des Hauptauslegers 5, indem die Hauptauslegerlängsachse kopfseitig um ca. 1° unter die Horizontalen gestellt wird. In der Regel wird eine derartige Neigung bereits durch das maximal mögliche Abwippen des Hauptauslegers auf Block erzielt. Übliche Wippwerke erreichen herbei eine Schrägstellung des Hauptauslegers 5 um ca. 1 bis maximal 2° gegenüber der Horizontalen.For the mating of the corresponding Verbolzstellen it is necessary that the Verbolzstellen of the
Genügt der hierdurch erzielte Neigungswinkel nicht den Montagevoraussetzungen, so kann die Neigung durch gezielte Ansteuerung der Achsfederung und gegebenenfalls der Kranabstützung 27 weiter gesteigert werden. Der Mobilkran 6 wird zunächst über die einstellbare Achsfederung abgelassen, um eine möglichst niedrige Arbeitshöhe zu ermöglichen. Im Anschluß wird der Mobilkran 6 über seine Abstützung 27 abgestützt. Insbesondere wird das vordere Paar 27a der Abstützung 27 gegenüber dem hinteren Paar 27b weiter ausgefahren, um die gewünschte Neigung des Mobilkrans 6 bzw. der Hauptauslegerlängsachse um den Winkel 30 einzustellen. Möglich ist hierdurch eine zusätzliche Neigung des Krans um ca.1 ° gegenüber der Horizontalen. Zu beachten ist herbei, dass die entsprechenden Paare 27a, 27b der Kranabstützung 27 derart ausgefahren werden, um die Kranquerachse horizontal auszurichten. Dabei sind gegebenenfalls Unebenheiten des Bodens zu berücksichtigen. Die abschließende Verbindung zwischen Hauptausleger 5 und Auslegerverlängerung 2 soll im entsprechenden Beschreibungsabschnitt der
Mehrere Detailaufnahmen der die jeweiligen Verbolzstellen 20, 20', 21, 21', 22, 22', 23, 23' tragenden Gitterstücke 1', 1c der Auslegerverlängerung 2 und des Spitzenauslegers 2' sind den Einzelzeichnungen der
Die Länge der Zugmittel 24, 24' ist speziell an die Gitterstückgeometrie angepaßt, kann jedoch bei Bedarf über einen vorgesehenen Verstellmechanismus längenverstellt werden. So kann zum Einen die Arbeitslänge erstmalig eingestellt und zum Anderen eine gewisse Längung während des Kranbetriebs kompensiert werden.
Nachdem die Gitterstücke über die Zugmittel 24, 24' verbunden worden sind, wird der Hauptausleger 5 über den Wippzylinder 25 geringfügig aufgewippt, um eine Spannung in den Zugmitteln 24, 24' zu erzeugen (Seitenansicht
Idealerweise wird der Hauptausleger soweit aufgerichtet, bis der Spitzenausleger 2' von der Ladefläche des Transportfahrzeuges 3 abhebt und seine Querachse vollständig horizontal ausgerichtet ist. In diesem Fall verläuft die Bolzenachse der Verbolzstellen 22, 22', 23, 23' ebenfalls horizontal. Da die Querachse des Hauptauslegers 5 bzw. der Auslegerverlängerung 2 bereits über die Abstützung 27 horizontal ausgerichtet wurde, verlaufen folglich alle Bolzenachsen der Verbindungsstellen 20, 20', 21, 21', 22, 22', 23, 23' zueinander parallel und horizontal.Ideally, the main boom is erected until the luffing jib 2 'lifts off the back of the
Im Anschluß werden die zu verbindenden Auslegererweiterungen 2, 2' aufeinander zu bewegt, bis die Verbolzstellen 20, 20', 21, 21' mit den Verbolzstellen 22, 22', 23, 23' gepaart und die Bolzen 26, welche aus der Transportlage entnommen worden sind, gesteckt werden können (Seitenansicht
Die Einzelzeichnungen a)-d) der
Im ersten Verfahrensschritt A werden durch Verfahren des Mobilkrans bzw. des Transportmittels 3 die beiden Gitterstücke 1c, 1' grob zueinander ausgerichtet, d.h. der Hauptausleger wird abgewippt und dadurch um einen definierten Winkel unter die Horizontale geneigt. In dieser Position können die Zugmittel angebracht werden. Beide Gitterstücke 1c, 1' nehmen die in der Zeile A, Spalten 100, 110, 120 skizzierte Lage ein. Der
Der verdrehten Lage des Gitterstückes 1' um seine Längsachse wird durch Aufwippen des Hauptauslegers abgeholfen. Die unter Spannung gestellten Zugmittel bewirken, dass sich das Gitterstück 1' zum Gitterstück 1c ausrichtet und die Verbindungsachsen ebenfalls horizontal ausgerichtet werden, wie es den Ansichten der Zeile B zu entnehmen ist.The twisted position of the lattice piece 1 'about its longitudinal axis is remedied by luffing the main boom. The traction means placed under tension cause the lattice piece 1 'to align with the
Durch Drehen des Kranoberwagens können die beiden Längsachsen der Gitterstücke 1c, 1' ausgerichtet werden, so dass diese in eine gemeinsame vertikale Ebene fallen, wie es in den Zeichnungen der Zeile C gezeigt ist. Ausgehend von diesem Zustand können die Gitterstücke 1c, 1' durch Teleskopieren des Hauptauslegers in eine Position mit zueinander fluchtenden Längsachse gebracht werden. Ferner wird eine Überdeckung der Verbolzstellen erriecht, so dass die Verbindungsbolzen gesteckt werden können (Zeile D).By rotating the crane superstructure, the two longitudinal axes of the
Die Demontage der Auslegererweiterungen 2, 2' erfolgt durch Umkehrung der voranstehend beschriebenen Verfahrensschritte. Der wesentliche Vorteil des erfindungsgemäßen Verfahrens bzw. des Mobilkrans 6 ist dadurch begründet, dass der erforderliche Aufwand für die Herstellung des Arbeits- bzw. Transportzustands des Krans 6 maßgeblich reduziert wird. Insbesondere lässt sich der notwendige Zeitaufwand für den Rüstvorgang verkürzen, was sich besonders positiv auf die anfallenden Betriebskosten auswirkt. Die montierten und arbeitsfähigen Auslegererweiterungen 2, 2' können unmittelbar nach dem Kraneinsatz zur nächsten Einsatzstelle transportiert und dort am nächsten Mobilkran eingesetzt werden. Selbstverständlich können mit den Zugmitteln 24, 24' auch mehrere verschiedene Auslegererweiterungen miteinander verbunden werden, nachdem diese von der zuerst hergestellten Verbindung getrennt wurden.The disassembly of the
Mögliche Ausführungsformen der Zugmittel 24, 24' sind in der
Als Alternative bietet sich die Verwendung eines einzelnen Zugmittels 34 (
Die einzelnen Zugmittel 24, 24', 34, 44 bestehen entweder aus ein oder mehreren Seilen, Ketten oder Klappstangen, die gegebenenfalls längenverstellbar ausgeführt sind. Unter Umständen kann ein einzelnes Zugmittel 24, 24', 34, 44 auch aus einer verknüpften Kombination aus einem oder mehreren Seilen, Ketten bzw. Klappstangen bestehen.The individual traction means 24, 24 ', 34, 44 consist either of one or more ropes, chains or folding rods, which are optionally made adjustable in length. Under certain circumstances, a single traction means 24, 24 ', 34, 44 also consist of a linked combination of one or more ropes, chains or folding rods.
