Description

Die Erfindung betrifft ein Lastaufnahmemittel zum Handhaben eines Hebegutes, vorzugsweise eines Teils einer Windkraftanlage, mittels einer kranartigen Hebeeinrichtung, so einem Kran oder einer vergleichbaren Hebeeinrichtung, um im Zusammenhang mit einem Transportvorgang, so einem Heben, die Lage des Hebegutes von einer Lager- in eine Montageposition zu verändern.The invention relates to a load handling device for handling a lifting material, preferably a part of a wind turbine, by means of a crane-like lifting device, such a crane or a comparable lifting device, in connection with a transport process, such a lifting, the position of the load from a storage in a Change mounting position.

Lastaufnahmemittel, bei denen während des Hebevorgangs eine Lageänderung des Hebegutes erfolgen kann, sind beispielsweise aus der EP 2 118 483 B1 bekannt. Beim Einsatz derartiger Lastaufnahmemittel hat sich gezeigt, dass für jedes Hebegut, so jede Nabe einer Windkraftanlage, gesondert eine Traverse angefertigt werden muss, weil das Lastaufnahmemittel der Größe und konstruktiven Gestaltung des Hebegutes ausgerichtet ist. Darüber hinaus besteht das Problem, dass bei Aufnahme des Hebegutes, nämlich einer Nabe einer Windkraftanlage, das Anlegen des Lastaufnahmemittels seitlich erfolgt und nach dem Festlegen und Beginn des Hebevorgangs die Nabe bereits auf eine Seite gekippt wird. Dies führt zu einer hohen Belastung des Bereichs der Nabe, der während des Kippvorgangs noch am Lagerboden aufliegt, was zu Beschädigungen führen kann.Lifting devices in which a change in position of the lifting material can take place during the lifting process are known, for example, from US Pat EP 2 118 483 B1 known. When using such lifting equipment has been shown that for each load, so every hub of a wind turbine, a traverse must be made separately, because the load-carrying means of the size and structural design of the load is aligned. In addition, there is the problem that when picking up the material to be lifted, namely a hub of a wind turbine, the application of the load-carrying means takes place laterally and after setting and beginning of the lifting operation, the hub is already tilted to one side. This leads to a high load of the region of the hub, which still rests on the bearing bottom during the tilting operation, which can lead to damage.

Darüber hinaus ist durch die seitliche Festlegung relativ viel Fläche notwendig, zumindest mehr Fläche, als wenn ein Lastaufnahmemittel über dem Hebegut angeordnet wird und dieses sodann gleichmäßig ohne Kippvorgang hebt.In addition, by the lateral fixing relatively much area necessary, at least more area than when a load-receiving means is disposed above the lifting material and this then raises evenly without tipping.

Ferner hat sich gezeigt, dass zum weiteren Ausrichten des Hebegutes in die Montageposition ein relativ hoher Kraftaufwand notwendig ist, weil das eine Drehzentrum des Lastaufnahmemittels mit dem Hebegut nicht mit dessen Schwerpunkt (COG, Centre of Gravity) übereinstimmt oder nahezu übereinstimmt.Furthermore, it has been found that a relatively high expenditure of force is necessary for further alignment of the lifting material in the mounting position, because the one center of rotation of the lifting device does not coincide with the lifting material with its center of gravity (COG, Center of Gravity) or nearly coincides.

Andere Varianten zur Ausrichtung des Hebegutes von einer Transport- in eine Montageposition sehen den Einsatz von zwei Kränen vor, was kostenintensiv ist.Other variants for aligning the load from a transport to a mounting position provide for the use of two cranes, which is costly.

Die Aufgabe der Erfindung besteht demgemäß darin, ein Lastaufnahmemittel bei dem im Zusammenhang mit dem Transportvorgang das Hebegut von einer Lager- in eine Montageposition verändert, insbesondere geneigt, werden kann, bereitzustellen, welches flexibler einsetzbar und nicht nur für ein bestimmtes Hebegut vorgesehen ist. Dabei sollte eine verbesserte Justierung des Hebegutes von der Lagerposition aus erfolgen. Vorteilhafterweise soll der Kraftaufwand für die Ausrichtung bzw. Lageänderung möglichst reduziert werden.The object of the invention is accordingly to provide a load-receiving means in which in connection with the transport process the load from a storage to a mounting position, in particular inclined, can be provided, which is more flexible and not only intended for a particular lifting. In this case, an improved adjustment of the material to be lifted should take place from the storage position. Advantageously, the force required for the alignment or change in position should be reduced as far as possible.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Vorrichtungsanspruchs 1, der Befestigungsanordnung gemäß Anspruch 20 und dem Verfahrensanspruch 21 gelöst, wobei die Unteransprüche weitere erfindungsgemäße Ausgestaltungsvarianten dieser Lösungen beinhalten.This object is achieved by the features of the device claim 1, the mounting arrangement according to claim 20 and the method claim 21, wherein the dependent claims include further inventive embodiments of these solutions.

Danach weist das erfindungsgemäße Lastaufnahmemittel zum Handhaben eines Hebegutes mittels einer kranartigen Hebeeinrichtung, so einem Kran oder einer vergleichbaren Hebeeinrichtung, eine Aufnahme zur Anordnung des Lastaufnahmemittels an die Hebeeinrichtung und mehrere Zugmittel zur Anordnung des Hebegutes an das Lastaufnahmemittel auf. Ferner besitzt es mindestens zwei drehbar gelagerte, arretierbare und die Zugmittel führende Rotationskörper, an welche jeweils mindestens ein Zugmittel festgelegt ist. Unter Festlegung ist zu verstehen, dass das jeweilige Zugmittel einseitig an dem jeweiligen Rotationselement festgelegt ist. Die Rotationskörper sind erfindungsgemäß mittels eines Antriebes steuerbar. Anstelle von kranartiger Hebeeinrichtung wird nachfolgend nur von Hebeeinrichtung gesprochen.Thereafter, the load receiving means according to the invention for handling a lifting material by means of a crane-like lifting device, such as a crane or a comparable lifting device, a receptacle for the arrangement of the load receiving means to the lifting device and a plurality of traction means for arranging the lifting material to the load receiving means. It also has at least two rotatably mounted, lockable and the traction means rotating body, to which at least one traction means is fixed. By definition is to be understood that the respective traction means is fixed on one side to the respective rotational element. The rotary bodies are controlled according to the invention by means of a drive. Instead of crane-type lifting device is only spoken by lifting device.

Die Rotationskörper selbst können gemeinsam oder unabhängig voneinander steuerbar sein. Ebenfalls kommt eine gleich- oder gegenläufige Steuerung in Betracht. Die Steuerung durch den Antrieb gewährt auch die Arretierbarkeit der Rotationskörper, sodass eine Lageänderung des Hebegutes gezielt steuerbar ist.The rotary bodies themselves may be controllable together or independently of each other. Likewise, an equal or opposite control comes into consideration. The control by the drive also ensures the lockability of the rotating body, so that a change in position of the lifting material is specifically controlled.

Bei einer unabhängigen Steuerung durch eine Drehbewegung mindestens eines Rotationskörpers kann beispielsweise die Lage des Hebegutes verändert werden. In diesem Fall liegt aber lediglich ein einseitiges Heben vor, das in bestimmten Konstellationen zur besseren Ausrichtung des Hebegutes genutzt werden kann.In an independent control by a rotational movement of at least one rotating body, for example, the position of the lifting material can be changed. In this case, however, there is only a one-sided lifting, which can be used in certain constellations for better alignment of the material to be lifted.

Allgemein ist durch eine gleich- oder gegenläufig gesteuerte Drehbewegung der Rotationskörper, in der Regel zwei, die Lage des Hebegutes veränderbar. Durch eine gleichläufige Drehbewegung der Rotationskörper ist das Hebegut kippbar und kann so für eine Montage ausgerichtet werden. Bei einer gegenläufigen Bewegung der Rotationskörper kommt es dagegen zu einem Heben des Hebegutes, was in bestimmten Fällen zur besseren Justierung des Hebegutes genutzt werden kann, so wenn beispielsweise nicht die Hebeeinrichtung, so ein Kranseil des Krans, betätigt werden kann.Generally, by a same or opposite direction controlled rotational movement of the rotary body, usually two, the position of the lifted material changeable. By a co-rotating rotational movement of the rotary body, the lifting material is tilted and can be aligned for assembly. In an opposite movement of the rotary body, however, there is a lifting of the lifting material, which can be used in certain cases for better adjustment of the material to be lifted, so if, for example, not the lifting device, such a crane crane rope, can be operated.

Durch eine Drehbewegung mindestens eines Rotationskörpers wird in der Regel ein an dem Rotationskörper festgelegtes Zugmittel von diesem aufgenommen oder freigegeben. Die Rotationsmittel führen so die Zugmittel. Das ist jedenfalls bei biegeschlaffen Zugmitteln, wie Ketten oder Seilen, der Fall, die durch die Drehbewegung entweder auf- oder abgewickelt werden. Es können aber auch biegesteife Zugmittel zum Einsatz kommen, wie Zugstangen, die an dem Rotationskörper exzentrisch beweglich festgelegt sind, sodass auch so die Rotationskörper die Zugmittel führen. Die Zugmittel der Rotationskörper können dabei gleich lang sein oder auch eine unterschiedliche Länge aufweisen, je nach konstruktiver Ausgestaltung und zu transportierendem Hebegut.As a result of a rotational movement of at least one rotational body, a traction means fixed to the rotational body is generally received or released by the rotational body. The rotation means so lead the traction means. In any case, this is the case with pliable traction means, such as chains or ropes, which are either wound up or unwound by the rotational movement. However, bending-resistant traction means can also be used, such as tie rods, which are fixed eccentrically movable on the rotation body, so that the rotational bodies also guide the traction means. The traction means of the rotating body can be the same length or have a different length, depending on the structural design and transported to be transported.

In weiterer Ausgestaltung der Erfindung sind die Rotationskörper wechselbar, um eine bessere Abstimmung des Lastaufnahmemittels auf ein bestimmtes Hebegut zu gewährleisten. Die Rotationskörper können ferner auf einer Achse gelegen sein oder sie sind unabhängig voneinander am Lastaufnahmemittel angeordnet. In diesem Fall erfolgt der Antrieb über zwei Teilantriebe, so beispielsweise zwei Motoren oder zwei Hydraulikantriebe.In a further embodiment of the invention, the rotary bodies are interchangeable in order to ensure a better matching of the load-carrying means to a specific load. The rotational bodies may also be located on an axis or they are arranged independently of each other on the load receiving means. In this case, the drive via two sub-drives, such as two motors or two hydraulic drives.

Als Rotationskörper können Seil- oder Kettenscheiben, Kurvenscheiben, Winden / Winschen oder Spills zum Einsatz kommen. Die Rotationskörper besitzen in der Regel eine radialsymmetrische oder nicht radialsymmetrische Form, sie können somit kreisförmig oder auch elliptisch geformt sein; aber auch teilkreisförmige oder teilelliptische Gestaltungen liegen im Rahmen der Erfindung. In weiterer Ausgestaltung der Erfindung weisen die Rotationskörper eine oder mehrere stirnseitige Rillen oder mehrere stirnseitige Zähne zur Aufnahme der Zugmittel auf.As a rotation body can rope or sprockets, cams, winches / winches or spills are used. The rotating bodies usually have a radially symmetric or non-radially symmetric shape, they can thus be circular or elliptical in shape; but also part-circular or partially elliptical designs are within the scope of the invention. In a further embodiment of the invention, the rotational body on one or more frontal grooves or more frontal teeth for receiving the traction means.

Des Weiteren können die Rotationskörper beispielsweise eine derartige Form und Größe besitzen, dass durch weniger als eine Umdrehung der Rotationskörper bei gleichläufiger Drehbewegung der Rotationskörper die Lage, in diesem Fall die Neigung des Hebegutes um 90 Grad veränderbar ist. Es ist somit um 90 Grad kippbar. Es sind aber grundsätzlich auch Rotationskörper vorstellbar, die eine derartige Form und Größe besitzen, dass durch weniger als eine Umdrehung mindestens eines Rotationskörpers die Lage des Hebegutes um 90 Grad veränderbar ist.Furthermore, the rotary bodies may, for example, have a shape and size such that the position, in this case the inclination of the material to be lifted, can be changed by 90 degrees by means of less than one rotation of the rotary body with the rotary body moving in the same direction. It is thus tiltable by 90 degrees. However, in principle rotational bodies are also conceivable which have such a shape and size that, by means of less than one rotation of at least one rotational body, the position of the lifting material can be changed by 90 degrees.

In einer Ausgestaltung der Erfindung weist das Lastaufnahmemittel eine Spreiztraverse auf, die auch wechselbar ausgestaltet sein kann. Ferner kann ihre Länge veränderbar sein. Die Spreiztraverse ist, sofern sie zum Einsatz kommt, im Bereich zwischen Rotationskörper und Hebegut an den Zugmitteln angeordnet.In one embodiment of the invention, the load-receiving means on a Spreiztraverse, which can also be configured changeable. Furthermore, their length can be changed. The Spreiztraverse is, if it is used, arranged in the region between the rotating body and lifting on the traction means.

Die Zugmittel des Lastaufnahmemittels selbst sind derart an den Rotationskörpern angeordnet, also festgelegt, dass sie sich jeweils gegenüberliegend in einem definierten Abstand zueinander von den mindestens zwei vorhandenen Rotationskörpern in Richtung einer zum Lastaufnahmemittel ebenfalls gehörenden Spreiztraverse und/oder des Hebegutes erstrecken, an welche sie jeweils angeordnet sind. Die Zugmittel verlaufen wegen des symmetrischen Aufbaus des Lastaufnahmemittels in der Regel jeweils sich gegenüberliegend. Der definierte Abstand ist dabei so ausgewählt, dass je nach Art des Hebegutes und Art und Anordnung der Rotationskörper sowie Art der Zugmittel eine Neigbarkeit des Hebegutes sichergestellt ist, um das Hebegut von einer Transport- in eine Montageposition zu bewegen. Ihr Abstand gegenüberliegend zueinander vergrößert sich in der Regel in Richtung des Hebegutes, an dem die Zugmittel auch jeweils sich gegenüberliegend in einem weiteren definierten Abstand zueinander angeordnet sind, der durch die Anschlagpunkte des Hebegutes bestimmt wird.The traction means of the lifting device itself are arranged on the rotating bodies, so determined that they each extend opposite each other at a defined distance from each other at least two existing rotational bodies in the direction of a load-receiving means also belonging Spreiztraverse and / or the lifted, to which they each are arranged. The traction means run because of the symmetrical structure of the lifting device usually each opposite each other. The defined distance is selected so that, depending on the type of material to be lifted and the type and arrangement of the rotary body and the type of traction means tiltability of the material to be lifted is ensured to move the load from a transport to a mounting position. Their distance opposite one another generally increases in the direction of the material to be lifted, on which the traction means are also respectively arranged opposite each other at a further defined distance from each other, which is determined by the attachment points of the material to be lifted.

Sofern eine Spreiztraverse zum Einsatz kommt, erlangen die Zugmittel auch durch die Spreiztraverse den definierten Abstand zueinander, der sich in Richtung der Spreiztraverse in der Regel vergrößert und im weiteren Verlauf in Richtung Hebegut in der Regel sodann parallel verläuft. Die konkrete Ausgestaltung der Spreiztraverse, so ihre Länge, ist jeweils an das zu transportierende Hebegut ausgerichtet, sodass eine Einsatzvariabilität gegeben ist. Die Zugmittel sind sodann an Endbereichen der Spreiztraverse und, wie bereits dargestellt, am Hebegut angeordnet.If a Spreiztraverse is used to obtain the traction means by the Spreiztraverse the defined distance from each other, which increases in the direction of the Spreiztraverse in the rule and in the further course in the direction of load usually then runs parallel. The specific design of the Spreiztraverse, so their length is aligned in each case to the transported material to be transported, so that a deployment variability is given. The traction means are then arranged on end portions of the spreader beam and, as already shown, on the load.

Das Hebegut ist in einer vorteilhaften Ausgestaltung der Erfindung derart an dem Lastaufnahmemittel anordenbar beziehungsweise bei Lastaufnahme, die von einer Lagerposition ausgeht, angeordnet, dass das Drehzentrum bzw. das virtuelle Drehzentrum des Lastaufnahmemittels, das je nach Ausgestaltung und Anordnung der Rotationskörper und der Spreiztraverse verschieden ist, und das Drehzentrum des Hebegutes vertikal verschoben auf einer Lotrechten gelegen sind, wobei der COG, der Schwerpunkt, des Hebegutes mit seinem Drehzentrum übereinstimmt. Dies gewährleistet ein leichteres Kippen des Hebegutes mit geringem Kraftaufwand und bringt daher Vorteile bei der Handhabung des Hebegutes. Zu beachten ist aber, dass sich der COG des Hebegutes in aller Regel beim Kippen in Kipprichtung verschiebt, wobei das Hebegut dann leichter kippt. Die Rotationskörper werden bei Erreichen der Montageposition wieder arretiert, was durch den Antrieb sichergestellt wird.In an advantageous embodiment of the invention, the material to be lifted can be arranged on the load-receiving means or, in the case of load-bearing starting from a storage position, arranged such that the center of rotation or the virtual center of rotation of the load-receiving means, which differs depending on the design and arrangement of the rotating body and the Spreiztraverse , and the center of rotation of the material to be lifted are vertically displaced on a vertical, the COG, the center of gravity, of the material to be lifted coinciding with its center of rotation. This ensures easier tilting of the material to be lifted with little effort and therefore brings advantages in handling the material to be lifted. It should be noted, however, that the COG of the lifting material usually shifts when tilting in the direction of tilt, whereby the load then tilts more easily. The rotating bodies are locked again on reaching the mounting position, which is ensured by the drive.

Als Antrieb der Rotationskörper kommen beispielsweise ein oder mehrere Motoren oder ein oder mehrere Hydrauliksteuerungen in Betracht, wobei jede Art von Antrieb prinzipiell eingesetzt werden kann.As a drive of the rotary body, for example, one or more motors or one or more hydraulic controls come into consideration, with each type of drive can be used in principle.

Die Handhabung des Hebegutes umfasst in der Regel ein Transport des Hebegutes ausgehend von einer Lagerposition vom Transportort in eine Montageposition am Montageort, einschließlich einer Lageänderung. Als Hebegüter kommen regelmäßig bauliche Anlagen oder Maschinen oder Teile von diesen in Betracht, wobei vorteilhafter Weise die baulichen Anlagen Windkraftanlagen und deren Teile sind, insbesondere Naben mit oder ohne Rotorblätter.The handling of the load usually includes a transport of the load from a storage position from the transport to a mounting position at the installation, including a change in position. As lifting goods are regularly structural equipment or machines or parts of these into consideration, wherein advantageously the structures are wind turbines and their parts, in particular hubs with or without rotor blades.

Der Transportvorgang des Hebegutes mittels der vorbeschriebenen Traverse von einem Transport- zu einem Montageort bei Veränderung der Lage, so der Neigung des Hebegutes, erfolgt erfindungsgemäß in folgenden Schritten.The transport process of the lifting material by means of the above-described traverse from a transport to a mounting location when changing the position, so the inclination of the material to be lifted, according to the invention in the following steps.

Zuerst wird das Lastaufnahmemittel zum Hebegut geführt, sodass es im Wesentlichen über dem Hebegut angeordnet ist.First, the load-carrying means is guided to the lifting material, so that it is arranged substantially above the lifting material.

Danach werden die Zugmittel gegenüberliegend in dem weiteren definierten Abstand zueinander an dem Hebegut festgelegt. Sie werden dabei funktionssicher an das Hebegut in bekannter Weise angeschlagen. Das Lastaufnahmemittel befindet sich dabei im Wesentlichen über dem Hebegut, sodass ein seitliches Angreifen bei größerem Raumbedarf entbehrlich ist. Die Rotationskörper sind dabei arretiert. Vorteilhafterweise, aber nicht erfindungsnotwenig, erfolgt die Anordnung bei Lastaufnahme wie vorbeschrieben, sodass das Drehzentrum des Lastaufnahmemittels und das Drehzentrum des Hebegutes vertikal verschoben auf einer Lotrechten gelegen sind, wobei der COG des Hebegutes mit seinem Drehzentrum übereinstimmt.Thereafter, the traction means are set opposite each other in the further defined distance from each other on the load. You will be struck functionally safe to the load in a known manner. The load-carrying means is located substantially above the load, so that a lateral attack in larger space is unnecessary. The rotating bodies are locked. Advantageously, but not erfindungsnotwenig, the arrangement is carried out at load picking as described above, so that the center of rotation of the lifting device and the center of rotation of the lifting vertically displaced are located on a perpendicular, the COG of the lifting material coincides with its center of rotation.

Eine Hebeeinrichtung, so ein Kran, hebt sodann das Hebegut an und transportiert dieses zu einem Montageort, wobei im Zusammenhang mit dem Transport - während oder nach dem Transport - die Lage, so beispielsweise die Neigung, des Hegegutes verändert wird, indem entweder der eine Rotationskörper der vorbeschriebenen Lastaufnahmevorrichtung nach Lösung seiner Arretierung durch seine gesteuerte Drehbewegung das an ihm festgelegte eine Zugmittel aufnimmt oder freigibt oder die mindestens zwei Rotationskörper nach Lösung ihrer Arretierung durch eine gleichläufige gesteuerte Drehbewegung das an dem ersten Rotationskörper festgelegte erste Zugmittel freigeben und das an dem weiteren Rotationskörper festgelegte weitere Zugmittel aufnehmen. Bei Erreichen des Montageortes nimmt dann das Hebegut seine Montageposition ein bzw. hat diese bereits eingenommen. Die Rotationskörper werden dann nach Änderung der Lage und der damit einhergehenden Einnahme der Montageposition erneut arretiert und das Hebegut kann sodann am Montageort montiert werden. Wenn im Zusammenhang mit dem Transport - während oder nach dem Transport - die Lage, so beispielsweise die Neigung, des Hebegutes verändert wird, dann kann dies gemäß dem erfindungsgemäßen Lastaufnahmemittel bereits auch vor Beginn des Transportvorgangs beginnen. Zu beachten ist aber, dass in diesem Fall durch leichtes Heben des Krans oder eine gegenläufige Bewegung der Rotationskörper das Hebegut leicht angehoben beziehungsweise justiert wird und sodann die vorbeschriebene Neigung erfolgt, um ein einseitiges Anheben des Hebegutes, so der Nabe der Windkraftanlage, auf dem Lagerboden und damit eine hohe Belastung der noch aufliegenden Kante der Nabe zu verhindern.A lifting device, such a crane, then lifts the load and transports it to a mounting location, wherein in connection with the transport - during or after transport - the position, such as the inclination of the goods is changed by either the one rotation body the above-described load bearing device after solving its locking by his controlled rotational movement which receives a traction means or releasing him or release the at least two rotating body after solving their locking by a co-rotating controlled rotational movement fixed to the first body of rotation first traction means and fixed to the other body of revolution take up further traction means. When the installation site is reached, the lifting material then assumes its mounting position or has already occupied it. The rotating bodies are then locked again after changing the position and the concomitant taking of the mounting position and the load can then be mounted at the installation site. If, in connection with the transport - during or after transport - the situation, such as the inclination, of the material to be lifted, then this can already begin according to the load handling device according to the invention before the start of the transport process. It should be noted, however, that in this case by slightly lifting the crane or an opposite movement of the rotating body, the lifting material is slightly raised or adjusted and then the prescribed inclination takes place to a one-sided lifting of the lifting material, so the hub of the wind turbine, on the storage floor and thus to prevent a high load on the still resting edge of the hub.

So kann beispielsweise eine Nabe einer Windkraftanlage von einer Lagerposition aufgenommen - Lastaufnahme - und um 90 Grad gedreht, die für dieses Bauteil erforderliche Montageposition, zur Windkraftanlage transportiert und zur Montage einfach positioniert werden, wobei das Lastaufnahmemittel durch seine Ausgestaltung für verschiedene Arten von Naben und anderen Bauteilen von Windkraftanlagen einsetzbar ist. Bei der Lagerposition ruht die Nabe in der Regel auf einer umlaufenden Kante ihrer Basis.For example, a hub of a wind turbine taken from a storage position - load picking - and rotated by 90 degrees, transported for this component assembly position, transported to the wind turbine and easily positioned for mounting, the load handling means by its design for different types of hubs and others Components of wind turbines can be used. In the storage position, the hub usually rests on a peripheral edge of its base.

Es wird somit ein Lastaufnahmemittel bereitgestellt, bei dem im Zusammenhang mit dem Hebevorgang das Hebegut von einer Lager- in eine Montageposition ausgerichtet werden kann, was jedoch flexibel für mehrere Hebegüter und nicht nur für ein bestimmtes Hebegut vorgesehen ist. Dabei ist es ferner möglich, je nach Anordnung des Hebegutes an dem Lastaufnahmemittel den Kraftaufwand für die Ausrichtung bzw. Lageänderung gegenüber der bekannten Vorrichtung zu reduzieren. Ferner kann mit dem erfindungsgemäßen Lastaufnahmemittel sowohl ein ein- oder beidseitiges Heben so über ein oder beide Rotationskörper gesteuert werden, als auch ein Kippen des Hebegutes. Auch ist so eine bessere Austarierung und Justierung gegenüber der bekannten Vorrichtung möglich. Gerade die mindestens zwei Rotationskörper mit ihren Zugmitteln gewährleisten eine verbesserte Einsatzvariabilität. Das trifft auch noch bei einem Einsatz der Spreiztraverse zu, gerade dann, wenn diese in ihrer Länge veränderbar ist, wobei die Spreiztraverse selbst ebenfalls einen vorbeschriebenen Antrieb zur Längensteuerung aufweisen kann. Eine fakultative Tauschbarkeit der Rotationskörper erhöht die Variabilität. Ferner ist ein seitliches Angreifen an die Nabe einer Windkraftanlage als Hebegut nicht notwendig, was ihre Flexibilität verbessert. Ferner muss die Nabe bei Aufnahme des Hebevorgangs nicht einseitig angehoben werden, wodurch eine Beschädigung der umlaufenden Kante ihrer Basis reduziert wird. Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Figur näher erläutert. Dabei ergeben sich weitere Vorteile, Merkmale und Ausgestaltungen der Erfindung.Thus, a load-receiving means is provided, in which, in connection with the lifting operation, the lifting material can be aligned from a storage position to an assembly position, but this is provided flexibly for a plurality of lifting goods and not only for a certain lifting goods. It is also possible, depending on the arrangement of the lifting material on the load-receiving means to reduce the force required for the alignment or change in position relative to the known device. Furthermore, with the load-carrying device according to the invention both a one- or two-sided lifting can be controlled via one or both bodies of rotation, as well as a tilting of the lifting material. Also, such a better balance and adjustment over the known device is possible. Especially the at least two rotating bodies with their traction means ensure an improved versatility. This is also true when using the Spreiztraverse, just when this is variable in length, the Spreiztraverse itself may also have a drive for length control described above. An optional interchangeability of the rotating bodies increases the variability. Furthermore, lateral engagement with the hub of a wind turbine as a lifting load is not necessary, which improves its flexibility. Furthermore, the hub does not have to be lifted on one side when the lifting operation is started, which reduces damage to the peripheral edge of its base. The invention will be explained in more detail using an exemplary embodiment with reference to the figure. This results in further advantages, features and embodiments of the invention.
