Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung, einen Kran eingangs erwähnter Art mit einfachen und kostengünstigen Mitteln so zu verbessern, dass eine vielseitige Verwendbarkeit ermöglicht wird.Proceeding from this, it is therefore the object of the present invention to improve a crane of the type mentioned at the beginning with simple and inexpensive means in such a way that it can be used in a variety of ways.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass an die an den Längs- und Querseiten des Kranmoduls vorgesehenen Andockelemente mit passenden Eingriffselementen versehene, bei auf seinen Stützbeinen aufgebocktem Kranmodul mittels des Auslegers manipulierbare Fahrwerksaggregate andockbar sind, die als an einen bestimmten Einsatzzweck angepasste, wahlweise einsetzbare Wechselaggregate ausgebildet sind.According to the invention, this object is achieved in that landing gear assemblies which can be manipulated by means of the boom and which can be manipulated by means of the boom when the crane module is jacked up on its support legs can be docked to the docking elements provided on the longitudinal and transverse sides of the crane module usable exchangeable units are formed.
Diese Maßnahmen stellen sicher, dass für jeden vorgesehenen Einsatzzweck des Krans die entsprechenden Fahrwerksaggregate angedockt werden können, wobei zum Andocken der gewünschten Fahrwerksaggregate der Kran auf den Stützbeinen seiner Stützbalken aufgebockt und die anzudockenden Fahrwerksaggregate mittels des Auslegers manipuliert werden können. Der erfindungsgemäße Kran ist daher sehr einfach und schnell auf jeden gewünschten Einsatz umrüstbar und damit variabel einsetzbar, was eine gute Auslastung und damit auch eine ausgezeichnete Wirtschaftlichkeit gewährleistet.These measures ensure that the corresponding chassis units can be docked for each intended use of the crane, the crane being jacked up on the support legs of its support beams and the ones to be docked to dock the desired chassis units Chassis units can be manipulated by means of the boom. The crane according to the invention can therefore be converted very easily and quickly to any desired use and can therefore be used variably, which ensures good utilization and thus excellent economic efficiency.
Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den Unteransprüchen angegeben.Advantageous refinements and expedient further developments of the superordinate measures are specified in the subclaims.
Gemäß einer ersten Ausführung können die Andockelemente direkt am Bett angebracht sein. Alternativ kann das Bett auf einer Ladeplattform aufgenommen werden, die ihrerseits mit den Andockelementen versehen ist. Dies ergibt in vorteilhafter Weise einen Nachrüstsatz, der eine einfache Nachrüstung bestehender Kräne mit den erfindungsgemäßen Maßnahmen ermöglicht. Gleichzeitig ist hierdurch sichergestellt, dass die bettseitig vorgesehenen Stützbalken kollisionsfrei über die der darunter sich befindenden Ladeplattform zugeordneten Andockelemente hinweggehen können. Natürlich können zwecks besonders hoher Vielseitigkeit auch sowohl am Bett als auch an der Ladeplattform Andockelemente angebracht sein.According to a first embodiment, the docking elements can be attached directly to the bed. Alternatively, the bed can be taken up on a loading platform, which in turn is provided with the docking elements. This advantageously results in a retrofit kit which enables existing cranes to be easily retrofitted with the measures according to the invention. At the same time, this ensures that the support beams provided on the bed side can pass over the docking elements assigned to the loading platform located below without collision. Of course, for the purpose of particularly high versatility, docking elements can also be attached to both the bed and the loading platform.
In weiterer Fortbildung der übergeordneten Maßnahmen können als Fahrwerksaggregate für eine Bewegung auf befestigtem Untergrund an zwei einander gegenüberliegenden Seiten, vorzugsweise an der Vorder- und Rückseite des Krans, jeweils wenigstens ein Wagenelement angedockt werden, das jeweils ein die den Andockelementen zugeordneten Eingriffselemente enthaltendes Fahrgestell und mindestens zwei paarweise angeordnete Rollen aufweist. Die vorne und hinten angedockten Wagenelemente, die kostengünstig bereitgestellt werden können, ermöglichen die Schaffung einer kompakten, auf einem befestigten Untergrund mobilen Krananordnung, wobei die Wagenelemente in vorteilhafter Weise auch mit einer Ladefläche ausgestattet sein und als beladbare Transporter dienen können.In a further development of the higher-level measures, at least one carriage element can be docked as chassis units for a movement on solid ground on two opposite sides, preferably on the front and rear of the crane, each of which contains a chassis containing the engagement elements assigned to the docking elements and at least has two rollers arranged in pairs. The car elements docked at the front and rear, which can be provided inexpensively, enable the creation of a compact crane arrangement that is mobile on a paved surface, the car elements advantageously also being equipped with a loading area and being able to serve as loadable transporters.
Die Rollen können als Einfachrollen für eine rollende Bewegung auf einem Hallenboden oder Werksgelände ausgebildet sein. Dies ermöglicht eine einfache Platzierung des Krans an der gewünschten Arbeitsposition. Alternativ können die Rollen auch als Straßenrollen ausgebildet sein, die zweckmäßig mit einer Schwerlastbereifung versehen sein können. Dies ergibt eine auf einer Straße verfahrbare Anordnung und macht es daher möglich, den Kran als Anhänger mittels einer Zugmaschine zu transportieren. Dabei kann ein vorderes Wagenelement zweckmäßig mit einer Anhängeeinrichtung versehen sein. Besonders zweckmäßig kann dabei ein an ein vorderes Wagenelement anbaubares Aufliegerelement vorgesehen sein, so dass ein an einen Sattelschlepper anhängbarer Anhänger entsteht.The rollers can be used as single rollers for a rolling motion on one Hall floor or factory premises. This enables the crane to be easily placed in the desired working position. Alternatively, the rollers can also be designed as road rollers, which can expediently be provided with heavy-duty tires. This results in an arrangement that can be moved on a road and therefore makes it possible to transport the crane as a trailer by means of a tractor. A front carriage element can expediently be provided with a trailer device. Particularly expediently, a trailer element that can be attached to a front wagon element can be provided, so that a trailer that can be attached to a semi-trailer is created.
Zur Bildung eines auf Schienen verfahrbaren Krans werden hinten und vorne jeweils wenigstens ein Wagenelement angedockt, das wiederum ein die den Andockelementen zugeordneten Eingriffselemente enthaltendes Fahrgestell und mindestens vier paarweise angeordnete, mit einem Spurkranz versehene Schienenlaufrollen aufweist, die an einem gemeinsamen Radträger gelagert sind, auf dem das Fahrgestell abgestützt ist. Diese Maßnahmen ergeben ein sicheres Schienenfahrzeug.To form a crane that can be moved on rails, at least one carriage element is docked at the rear and at the front, which in turn has a chassis containing the engagement elements assigned to the docking elements and at least four rail rollers arranged in pairs, provided with a flange and mounted on a common wheel carrier on which the chassis is supported. These measures result in a safe rail vehicle.
Zweckmäßig kann dabei jedes an einem Ende freie Wagenelement im Bereich seines freien Endes mit einer Anhängeeinrichtung zum Anhängen an einen jeweils benachbarten Waggon eines Zugs versehen sein. Auf diese Weise kann der erfindungsgemäße Ladekran einfach in einen mit einer Lokomotive ausgestatteten Zug integriert werden und benötigt daher keinen eigenen Antrieb.Appropriately, each carriage element free at one end can be provided in the region of its free end with a hitching device for hanging on a respective adjacent wagon of a train. In this way, the loading crane according to the invention can be easily integrated into a train equipped with a locomotive and therefore does not need its own drive.
Zusätzlich oder alternativ zu einer Anhängeeinrichtung kann vorgesehen sein, wenigstens ein angedocktes Wagenelement mit antreibbaren Rollen versehen ist. Dieses Wagenelement kann direkt an das Bett beziehungsweise die Ladeplattform oder an ein dort bereits angedocktes Wagenelement angedockt werden. Auf diese Weise lässt sich einfach eine hohe Unabhängigkeit von einer zusätzlichen Zugmaschine etc. erreichen.In addition or as an alternative to a hitching device, at least one docked carriage element is provided with drivable rollers. This trolley element can be docked directly to the bed or the loading platform or to a trolley element already docked there. In this way, a high degree of independence from an additional tractor, etc. can easily be achieved.
In weiterer Fortbildung der übergeordneten Maßnahmen können als Fahrwerksaggregate für eine Bewegung in unbefestigtem Gelände zwei einander gegenüberliegende, antreibbare Raupenfahrwerkselemente vorgesehen sein, die wahlweise an den Längs- oder Querseiten des Krans angedockt werden können. Diese Maßnahmen ermöglichen eine Einsetzbarkeit des erfindungsgemäßen Krans auch in unbefestigtem Gelände und ermöglichen eine Fahrtrichtung wahlweise in Längs- oder Querrichtung des Krans und damit eine hohe Vielseitigkeit.In a further development of the higher-level measures, two opposing, drivable crawler track elements can be provided as chassis units for movement in unpaved terrain, which can be docked either on the longitudinal or transverse sides of the crane. These measures enable the crane according to the invention to be used even in unpaved terrain and enable a direction of travel either in the longitudinal or transverse direction of the crane and thus a high level of versatility.
Zweckmäßig kann ferner vorgesehen sein, dass die wenigstens einer Seite des Krans zugeordneten Andockelemente in Richtung des hieran andockbaren Fahrwerksaggregats seitlich ausfahrbar sind. Dies ermöglicht auf einfache Weise eine Vergrößerung der Spurweite.It can also expediently be provided that the docking elements assigned to at least one side of the crane can be extended laterally in the direction of the chassis unit that can be docked thereon. This enables the track width to be increased in a simple manner.
Vorteilhaft können die Andockelemente jeweils ein Flanschpaar mit zwei parallelen, nach außen abstehenden, vertikalen Flanschen und die Eingriffselemente jeweils ein Flanschpaar mit zwei parallelen, vertikalen, das das zugeordnete Andockelement bildende Flanschpaar innen oder außen flankierenden Flanschen aufweisen, wobei ein Flanschpaar eine entgegen der Eingriffsrichtung offene Kerbe und das jeweils andere Flanschpaar einen in die Kerbe des ersten Flanschpaars einlegbaren Querbolzen trägt und wobei wenigstens zwei einander benachbarte Flansche, vorzugsweise alle Flansche der beiden Flanschpaare, eine fluchtende Querbohrung für einen durchsteckbaren Querriegel aufweisen. Diese Maßnahmen ergeben eine Schnellkupplung zur kippsicheren und wackelfreien Andockung jedes Fahrwerksaggregats und damit insgesamt eine hohe Bedienungsfreundlichkeit und Sicherheit.Advantageously, the docking elements can each have a pair of flanges with two parallel, outwardly protruding, vertical flanges and the engagement elements each have a pair of flanges with two parallel, vertical flanks flanking the associated docking element inside or outside, with one pair of flanges being open against the direction of engagement Notch and the other pair of flanges carries a transverse bolt that can be inserted into the notch of the first pair of flanges, and at least two adjacent flanges, preferably all of the flanges of the two pairs of flanges, have an aligned transverse bore for a cross bar that can be pushed through. These measures result in a quick coupling for the tilt-proof and wobble-free docking of each chassis unit and thus overall a high level of user-friendliness and safety.
Eine weitere Fortbildung der übergeordneten Maßnahmen kann darin bestehen, dass an freien, seitlichen Andockelementen jeweils wenigstens eine mit entsprechenden Eingriffselementen versehene Querstrebe andockbar ist, die mit an ihrem gegenüberliegenden Ende ebenfalls vorgesehenen Eingriffselementen an freien seitlichen Andockelementen eines weiteren Krans andockbar ist. Hiermit lässt sich in vorteilhafter Weise ein Kranverbund mit mehreren, aneinander angedockten Kränen erreichen, die in einer gewünschten Weise zusammenwirken können, was bei bestimmten Einsatzfällen zur Steigerung der Gesamttragfähigkeit erwünscht sein kann.A further development of the superordinate measures can consist in the fact that at least one cross strut provided with corresponding engagement elements can be docked on free, lateral docking elements, which can be docked with engagement elements also provided at its opposite end on free lateral docking elements of a further crane. This can be advantageously achieve a crane network with several cranes docked to one another, which can interact in a desired manner, which can be desirable in certain applications to increase the overall load-bearing capacity.
Weitere vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den restlichen Unteransprüchen angegeben und aus der nachstehenden Beispielsbeschreibung anhand der Zeichnung näher entnehmbar.Further advantageous refinements and expedient developments of the superordinate measures are specified in the remaining subclaims and can be found in more detail in the following description of the example with reference to the drawing.

Anstelle der dargestellten Ausführung mit zwei Flanschpaaren wäre es natürlich auch denkbar, eines der Flanschpaare durch einen vom jeweils anderen Flanschpaar flankierten Klotz zu ersetzen. So könnte beispielsweise anstelle der das Andockelement 10 bildenden Flansche 10a, b ein mittiger, die Kerbe 13 und Querbohrung 16 aufweisender Klotz vorgesehen sein, der von den den Querbolzen 14 tragenden Flanschen 11a, b außen flankiert wird. Ebenso wäre es denkbar, anstelle der Flansche 11a, b einen mittigen Klotz vorzusehen, der von den Flanschen 10a, b außen flankiert wird und der anstelle des Querbolzens 14 nach außen auskragende Stummel aufweist, welche zum Eingriff in die Kerbe 13 der Flansche 10a, b gebracht werden können. Für die Querbohrung 16 gilt dasselbe wie vorher.Instead of the embodiment shown with two pairs of flanges, it would of course also be conceivable to replace one of the pairs of flanges with a block flanked by the other pair of flanges. For example, instead of the flanges 10a, b forming the

Mit Hilfe der Rollen 20 kann der gesamte Kran am Einsatzort verschoben und so in eine exakte Einsatzposition gebracht werden. Bei den für eine derartige Rollbewegung vorgesehenen Rollen kann es sich um Einfachrollen ohne oder nur mit einfacher Bereifung handeln. Es wäre aber auch denkbar, für eine Straßenfahrt geeignete Rollen vorzusehen. Dabei kann es sich dann um mit einer geeigneten Schwerlastbereifung versehene Rollen handeln. In jedem Fall ermöglichen die angedockten, mit Rollen 20, 20a versehenen Wagenelemente 18 die erwünschte Mobilität auf befestigtem Untergrund.With the help of the
