Description

Die Erfindung betrifft ein Fahrwerk für weit ausladende Arbeitsvorrichtungen gemäß dem Oberbegriff des Anspruchs 1 und 2. Hierbei ist unter "weitausladend" zu verstehen, daß die Arbeitsvorrichtung zumindest im zu transportierenden Zustand weitausladend ist. Insbesondere betrifft die Erfindung ein Fahrwerk für einen Bauhochkran, besonders bevorzugt für einen untendrehenden Baukran, wobei das Fahrwerk eine Doppel- oder Tandemachse besitzt, die eine vordere und hintere Achse umfaßt.The invention relates to a chassis for wide working devices according to the preamble of claim 1 and 2. Here it is to be understood by "far reaching" that the working device at least in the condition to be transported is expansive. In particular, the invention relates to a Chassis for a high-rise building crane, particularly preferred for one rotating crane, the chassis being a double or Has tandem axle that includes a front and rear axle.

Nach dem Stand der Technik, beispielsweise gemäß der FR-A-2 155 850, die ein Fahrwerk gemäß dem Oberbegriff des Anspruchs 1 und 2 offenbart, sind Bauhochkräne, insbesondere untendrehende Baukräne, mit Fahrwerk bekannt, bei denen das Fahrwerk, nachdem der Bauhochkran mittels desselben an den Aufstellungsort transportiert worden ist, vor dem Aufstellen des Bauhochkrans abmontiert wird. Denn wegen der relativ sehr großen Länge, die ein solcher Bauhochkran im zusammengelegten Zustand hat, ist es äußerst schwierig und in vielen Fällen sogar immöglich, den Bauhochkran im bebauten Gelände aufgrund der Enge des zur Verfügung stehenden Platzes an den genauen Aufstellungsort zu rangieren, wenn sich der Bauhochkran noch im zusammengelegten Zustand befindet.According to the prior art, for example according to FR-A-2 155 850, which is a landing gear according to the preamble of the claim 1 and 2 disclosed, are high construction cranes, in particular rotating Construction cranes, known with running gear, where the running gear, after the construction crane by means of the same to the installation site has been transported before the construction crane is erected is dismantled. Because because of the relatively very long length, such a construction crane in the collapsed state it is extremely difficult and in many cases even impossible the construction crane in the built-up area due to the narrowness of the available space at the exact location to maneuver when the construction crane is still merged Condition.

So muß bei dem Bauhochkran nach der FR-A-2 155 850 das für den Überlandtransport des Bauhochkrans zum Aufstellungsort anmontierte Fahrwerk am Aufstellungsort abmontiert werden, um den Bauhochkran mittels Schienenraddrehgestellen, die permanent daran angebracht sind, an der Baustelle auf Schienen rangieren und verfahren zu können.So with the high-rise crane according to FR-A-2 155 850 that for the Overland transport of the construction crane installed on site The undercarriage can be dismantled at the place of installation Construction crane using rail wheel bogies that are permanent attached to it, maneuvering on rails at the construction site and to be able to move.

Da das Ab- und Anmontieren des Fahrwerks für den Überlandtransport zeitaufwendig ist, verursacht das Aufstellen und Abbauen des Bauhochkrans relativ hohe Kosten und eine entsprechende zeitliche Planung, wobei es zur Behinderung von vom Bauhochkran unabhängigen Bauarbeiten kommen kann. Außerdem muß das Fahrwerk während der Aufstellungszeit des Bauhochkrans anderweitig untergebracht werden, was einen entsprechenden Platzbedarf und gegebenenfalls zusätzliche Transportkosten erfordert.Since the removal and removal of the chassis for overland transport is time consuming, causes erection and dismantling of the high-rise construction crane relatively high costs and a corresponding scheduling, whereby it hinders from from Construction crane independent construction work can come. In addition, must the undercarriage elsewhere during the erection of the construction crane be housed what a corresponding Requires space and possibly additional transport costs.

Für den Überlandtransport ist daher aus der FR-A-2 155 850 ein Bauhochkran bekannt, der zusätzlich zu den Merkmalen des Oberbegriffs des Anspruchs 1 und 2 auch noch die Merkmale des Anspruchs 11 aufweist. Für den Überlandtransport wird das freie Ende des zusammengelegten und horizontal ausgerichteten Kranturms auf einem Zugfahrzeug angebracht, so daß die Zugkraft des Zugfahrzeugs über den Kranturm und den Kranunterbau auf das Fahrgestell des Krans übertragen und so der Kran mit seinem Fahrgestell beim Überlandtransport über die Straße gezogen wird.For the overland transport is therefore from FR-A-2 155 850 Construction crane known in addition to the features of the generic term of claims 1 and 2 also the features of the claim 11 has. For the overland transport the free End of the collapsed and horizontally aligned crane tower mounted on a towing vehicle so that the traction of the towing vehicle over the crane tower and the crane substructure transferred the chassis of the crane and so the crane with his Chassis pulled across the road during overland transport becomes.

Zur Lenkung des Fahrgestells des Krans wird das dessen Räder verbindende Lenkgestänge mittels zweier Stränge eines elastischen Seils mit dem Fahrgestell des Zugfahrzeugs über je eine Seilumlenkrolle so verbunden, daß der eine Seilstrang von der Achsschenkellenkung der linken vorderen Räder des Fahrgestells des Krans über die eine Seilumlenkrolle zu der rechten hinteren Seite des Fahrgestells des Zugfahrzeugs verläuft, und der andere Seilstrang verläuft symmetrisch zum ersteren. Durch diese Zwangslenkung wird die Kurvenfahrt des Zugfahrzeugs aufgrund der Seilspannung in eine Lenkung des Fahrgestells des Krans umgesetzt. To steer the chassis of the crane, this becomes its wheels connecting steering linkage by means of two strands of an elastic Rope with the chassis of the towing vehicle over one each Rope pulley connected so that one rope strand from the Axle steering of the left front wheels of the chassis of the crane over the rope pulley to the right rear Side of the chassis of the towing vehicle runs, and the other rope run runs symmetrically to the former. By this forced steering is due to the cornering of the towing vehicle the rope tension in a steering of the chassis of the Crane implemented.

Ein derartiges Fahrwerk mit einer solchen Zwangslenkung ist zwar für den Überlandtransport eines Krans ausreichend, wofür es gemäß der FR-A-2 155 850 auch nur bestimmt ist, es ist jedoch für ein Rangieren des Krans an der Baustelle unter verhältnismäßig beengten Platzverhältnissen überhaupt nicht geeignet, d.h. ein solches Rangieren ist mit einem derartigen Fahrwerk nicht möglichSuch a chassis with such a forced steering is Sufficient for the overland transport of a crane, for what it is only determined according to FR-A-2 155 850, but it is for maneuvering the crane at the construction site under proportionately cramped space not suitable at all, i.e. such maneuvering is with such Chassis not possible

Aufgabe der Erfindung ist es, ein Fahrwerk, insbesondere für einen Bauhochkran, vorzugsweise einen untendrehenden Baukran, zur Verfügung zu stellen, das es ermöglicht, weit ausladende Arbeitsvorrichtungen, wie insbesondere Bauhochkräne, in Schnellmontage und unter relativ beengten Platzverhältnissen praktisch problemlos mit dem Überlandfahrwerk aufzustellen.The object of the invention is a chassis, in particular for a construction crane, preferably a non-rotating construction crane, to provide, which makes it possible to reach far Working devices, such as, in particular, construction cranes, in Quick assembly and in relatively confined spaces practically easy to set up with the overland chassis.

Diese Aufgabe wird in einem ersten Aspekt mit einem Fahrwerk gemäß dem Oberbegriff des Anspruchs 1 gelöst, welches das erste kennzeichnende Merkmal und eines oder mehrere der alternativen Merkmale (1) bis (3) des Kennzeichens dieses Anspruchs aufweist.This task is done in a first aspect with a chassis solved according to the preamble of claim 1, which the first distinctive feature and one or more of the alternative Features (1) to (3) of the characterizing part of this claim having.

Durch den vorstehenden Aufbau sind die erste und zweite Achse 3 bzw. 4 lenkgeometrisch synchron verstellbar, und mit Hilfe dieser Lenkung wird ein ausgezeichnetes Rangieren des erfindungsgemäßen Fahrwerks 2, vorliegend Bauhochkran 1, an der Baustelle ermöglicht, -insbesondere kann ein leichtes Einrangieren in enge Baustellen-Einfahrten bewerkstelligt werden.Due to the above structure, the first and second axes are 3 or 4 steering geometrically adjustable, and with the help this steering is an excellent maneuvering of the invention Chassis 2, in the present high-rise crane 1, on the Construction site enables, in particular, easy maneuvering in narrow construction site entrances.

Die Lenkeinrichtung ist, z.B. vorliegend für den Krantransport, in der Geradeausfahrposition durch eine Arretierung 62 (siehe Figur 2) arretierbar, und zwar in der dargestellten Ausführungsform durch einen Sicherungsbolzen 25 (siehe Figur 1), der in zwei miteinander fluchtende Hülsen 26 und 27 einsteckbar ist, von denen die eine Hülse 26 am Fahrgestell 15 und die andere Hülse 27 an dem einen der beiden Drehgestelle 12a, 12b fest angebracht ist, so daß bei eingefügtem Sicherungsbolzen 25 beide über die Kraftübertragung 18 miteinander zwangsgekoppelten Drehgestelle, die zusammenfassend mit 12 bezeichnet werden, in der Geradeausfahrposition arretiert sind.The steering device is e.g. in the present case for crane transport, in the straight-ahead driving position by a lock 62 (see Figure 2) lockable, in the illustrated Embodiment by a securing bolt 25 (see figure 1), which can be inserted into two sleeves 26 and 27 aligned with one another is one of which a sleeve 26 on the chassis 15th and the other sleeve 27 on one of the two bogies 12a, 12b is firmly attached so that when the securing bolt is inserted 25 both via the power transmission 18 with each other positively coupled bogies, collectively designated 12 are locked in the straight ahead driving position.

Die Zugeinrichtung 28 (siehe insbesondere Figur 1) bildet einen vom Fahrgestell 15 gesonderten Teil des Fahrwerks 2 und ist insgesamt am Bauhochkran 1, vorliegend am unteren Kranturmabschnitt 9a, angebracht und durch denselben mit dem Fahrwerk 2 verbunden. Wenn anstelle des Krans 1 eine andere, ähnlich weit ausladende Arbeitsvorrichtung, wie beispielsweise eine extrem lange Feuerwehrleiter, ein Langrohrgeschütz, eine Raketenabschußrampe oder dgl. mit dem erfindungsgemäßen Fahrwerk 2 ausgerüstet ist, dann ist auch hier die Zugeinrichtung an dem in Transportfahrtrichtung vorderen Endbereich der Arbeitsvorrichtung angebracht, und die Arbeitsvorrichtung bildet ebenso wie vorliegend der Kran 1 funktionell einen Teil des gesamten "Fahrgestells", indem sie die Zugeinrichtung mit dem Fahrwerk 2 bzw. dessen Fahrgestell 15 verbindet.The traction device 28 (see in particular FIG. 1) forms one from the chassis 15 separate part of the chassis 2 and is in total on the construction crane 1, in the present case on the lower section of the crane tower 9a, attached and by the same with the chassis 2 connected. If instead of crane 1 another, similar wide working device, such as an extremely long fire ladder, a long barrel gun, one Rocket launcher or the like. With the landing gear according to the invention 2 is equipped, then here is the pulling device at the front end region of the working device in the transport direction attached, and forms the working device just as in the present case the crane 1 functionally part of the entire "chassis" by connecting the drawbar with the Chassis 2 or its chassis 15 connects.

Die Zugeinrichtung 28 besteht in der vorliegenden Ausführungsform im wesentlichen aus einem Führungsrohr 42, einem Zugrohr 29, einer Schleifplatte 30 und einem Sattelzapfen 31. Das Zugrohr 29 ist mittels des Führungsrohrs 42 zu einer Ein- und Ausschiebebewegung geführt, wie in Figur 1 dargestellt ist, wo das Zugrohr 29 durch strichpunktierte Linien in der herausgeschobenen Position und durch ausgezogene Linien in der eingeschobenen Position dargestellt ist. Am vorderen Ende des Zugrohrs 29 befindet sich eine Zugöse 32, die am Zugrohr 29 angeschraubt ist, so daß die Arbeitsvorrichtung 1, in der vorliegend bevorzugten Ausführungsform, also der gezeigte Bauhochkran, über die Zugöse 32 mit der Bolzenkupplung eines Lastkraftwagens verbunden werden kann. Das Zugrohr 29 ist an dem Führungsrohr 42 arretierbar, und zwar vorliegend mittels zweier Steckbolzen 33; und das Führungsrohr 42 ist über Befestigungsplatten 43 an der Arbeitsvorrichtung 1, vorliegend am Kranturmabschnitt 9a, befestigt.The pulling device 28 is in the present embodiment essentially from a guide tube 42, a draw tube 29, a grinding plate 30 and a saddle pin 31. Das Draw tube 29 is by means of the guide tube 42 to an input and Extending movement performed, as shown in Figure 1, where the draw tube 29 by dash-dotted lines in the pushed out Position and by solid lines in the inserted Position is shown. At the front end of the There is a towing eye 32 on the pull tube 29, which is on the pull tube 29 is screwed so that the working device 1, in the present preferred embodiment, that is the construction crane shown, via the drawbar eye 32 with the pin coupling one Truck can be connected. The draw tube 29 is on the guide tube 42 can be locked, in the present case by means of two socket pins 33; and the guide tube 42 is over mounting plates 43 on the working device 1, in the present case on Crane tower section 9a attached.

Unter dem Führungsrohr 28 ist die Schleifplatte 30 befestigt, beispielsweise durch Anschweißen, und an dieser Schleifplatte 30 ist der Sattelzapfen 31 angebracht, beispielsweise angeschraubt, so daß die Arbeitsvorrichtung 1 dadurch mit der Sattelkupplung an einem Lastkraftwagen oder einem Sattelschlepper verbunden werden kann, nachdem das Zugrohr 29 in die eingeschobene Position gebracht und in dieser mittels der Steckbolzen 33 arretiert worden ist.The grinding plate 30 is fastened under the guide tube 28, for example by welding, and on this grinding plate 30 the saddle pin 31 is attached, for example screwed on, so that the working device 1 thereby with the fifth wheel on a truck or semi-trailer can be connected after the draw tube 29 is inserted into the Positioned and in this by means of the plug pins 33 has been arrested.

Die Abstützung der Arbeitsvorrichtung 1, vorliegend des Bauhochkrans, erfolgt mittels Abstützfüßen 36, von denen, wie die Figur 5 zeigt, vier in zentralsymmetrischer Anordnung vorgesehen sind, wobei dieselben vorzugsweise als Hydraulik-Abstützfüße ausgebildet sind, die durch ein Hydraulikaggregat 22 versorgt werden (siehe Figur 2). Diese ermöglichen - im Gegensatz zu den herkömmlichen mechanischen Abstützspindeln - ein schnelles und mittels einer elektronischen Nivelliereinrichtung (nicht gezeigt) automatisches Ausnivellieren und Aufstellen der Arbeitsvorrichtung 1, wie des Bauhochkrans, ohne großen Kraftaufwand durch nur eine einzige Bedienungsperson, insbesondere eine flexible Montage und Demontage auf schwierigstem Gelände bzw. Baugelände.The support of the working device 1, in the present case the construction crane, takes place by means of support feet 36, of which, like that Figure 5 shows four provided in a centrally symmetrical arrangement are, preferably the same as hydraulic support feet are formed, which are supplied by a hydraulic unit 22 be (see Figure 2). In contrast, these enable to the conventional mechanical support spindles - a fast and by means of an electronic leveling device (not shown) automatic leveling and setting up the working device 1, such as the construction crane, without large Exertion of force by only one operator, in particular flexible assembly and disassembly on the most difficult Terrain or building site.

Wie die Figur 5 weiter zeigt, sind die Räder 11 des Fahrwerks 2 innerhalb des Bereichs der Abstützfläche der Arbeitsvorrichtung 1, also hier des Bauhochkrans, angeordnet, d.h. der Fläche, welche von einer die Abstützfüße 36 miteinander verbindenden Linie umschlossen wird.As FIG. 5 further shows, the wheels 11 of the undercarriage 2 within the area of the support surface of the working device 1, i.e. here of the high-rise crane, i.e. the area, which of a connecting the support feet 36 together Line is enclosed.

Die Hydraulik-Abstützfüße 36 haben ein entsperrbares Rückschlagventil integriert und als zusätzliche Sicherheit einen Absperrhahn pro Abstützfuß 36 eingebaut.The hydraulic support feet 36 have an unlockable check valve integrated and one as additional security Shut-off valve installed per support foot 36.

Die Abstützfüße 36 werden durch das Hydraulik-Aggregat 22 mit Hydrauliköl versorgt und können auch unabhängig von der automatischen elektronischen Nivelliereinrichtung einzeln mittels Handsteuerventilen 37 (siehe Figur 2) angesteuert werden, die erste Steuerventile 37a für die Abstützfüße auf der einen Seite des Fahrwerks 2 und zweite Steuerventile 37b für die Abstützfüße auf der anderen Seite des Fahrwerks 2 umfassen (siehe Figur 2). Die Stromversorgung des Hydraulikaggregats 22 erfolgt im Arbeitseinsatz vom Schaltschrank des Bauhochkrans 1 aus.The support feet 36 are supported by the hydraulic unit 22 Hydraulic oil is supplied and can also be used independently of the automatic electronic leveling device individually by means of Manual control valves 37 (see Figure 2) can be controlled first control valves 37a for the support feet on one side of the chassis 2 and second control valves 37b for the support feet on the other side of the chassis 2 (see Figure 2). The power supply of the hydraulic unit 22 takes place when working from the control cabinet of the construction crane 1 out.

Wie Figur 7 durch die dortigen vier Pfeile veranschaulicht, sind die Abstützfüße 36 aus einer an das Fahrgestell 15 beigeklappten Transportposition (gestrichelte Darstellung) in ihre Arbeitsposition (ausgezogene Linien) seitlich ausklappbar und zum Transport wieder beiklappbar.As illustrated by the four arrows there, are the support feet 36 from a folded to the chassis 15 Transport position (dashed line) in your Working position (solid lines) can be folded out sideways and collapsible for transport.

Außerdem sind noch, wie Figur 2 zeigt, Anschlüsse 57 für Versorgungsleitungen, ein Hauptschalter 59 und ein Staukasten 61 auf dem Fahrgestell 15 vorgesehen. In addition, as FIG. 2 shows, there are connections 57 for supply lines, a main switch 59 and a storage box 61 provided on the chassis 15.

Wie die Figur 4 veranschaulicht, braucht das Zugrohr 29 zum Aufstellen der Arbeitsvorrichtung 1, vorliegend des Bauhochkrans, nur in die eingeschobene Position gebracht zu werden, um nicht in störenden Eingriff mit einem Teil der Arbeitsvorrichtung 1, wie vorliegend mit dem Kranausleger 10 bzw. dem daran vorgesehenen Laufwerk 34, zu kommen. Infolgedessen kann das Führungsrohr 42, in dem das Zugrohr 29 geführt ist, starr an der Arbeitsvorrichtung 1, wie z.B. am Kranturm 9, angebracht sein und in diesem Zustand an der vollständig aufgestellten Arbeitsvorrichtung 1 bzw. dem Bauhochkran verbleiben, wie die Figur 6 veranschaulicht. In Figur 4 sind durch Pfeile 39, 40 und 41 die Verschwenkbewegungen des unteren und oberen Kranturmabschnitts 9a, 9b und der Kranauslegerabschnitte 10a, 10b beim Aufstellen des Krans angedeutet.As illustrated in FIG. 4, the draw tube 29 needs to Setting up the working device 1, in the present case the construction crane, just to be put in the inserted position so as not to interfere with part of the working device 1, as in the present case with the crane boom 10 or the provided drive 34 to come. As a result, can the guide tube 42, in which the draw tube 29 is guided, rigid on the working device 1, e.g. attached to crane tower 9 be and in this condition at the fully erected Work device 1 or the high-rise crane remain, as Figure 6 illustrates. In Figure 4 are by arrows 39, 40 and 41 the pivoting movements of the lower and upper Crane tower sections 9a, 9b and crane boom sections 10a, 10b indicated when setting up the crane.

Die Kran-Gegengewichte 35 können, wie die Figur 1 zeigt, am zusammengelegten Bauhochkran 1 während dessen Transport verbleiben.The crane counterweights 35 can, as shown in FIG. 1, on folded construction crane 1 remain during its transport.

Schließlich kann am Kranturm 9, insbesondere am unteren Kranturmabschnitt 9a, ein klappbarer und in der Höhe veränderbarer Stützfuß 38 abnehmbar (Fig. 1) oder beiklappbar (Fig. 8 und 9) angebracht sein, um die weit über das Fahrwerk 2 hinausragende Arbeitsvorrichtung 1, wie den Bauhochkran, in dem Zustand derselben, in dem sie nicht an einen Lastkraftwagen oder eine Zugmaschine angekuppelt ist, abzustützen. Dieser Stützfuß 38 hat in Fig. 8 und 9 ein Rad 39, mit dem er auch beim Rangieren der Arbeitsvorrichtung 1 abgestützt werden kann.Finally, the crane tower 9, in particular the lower crane tower section 9a, a foldable and changeable in height Support foot 38 removable (Fig. 1) or foldable (Fig. 8 and 9) be attached to the projecting far beyond the chassis 2 Working device 1, such as the construction crane, in the same state, in which they are not connected to a truck or a Tractor is coupled to support. This support foot 38 8 and 9 has a wheel 39, with which it also when maneuvering the working device 1 can be supported.

Die Figuren 8 und 9 zeigen das in Transportrichtung des zusammengelegten Krans vordere Ende desselben mit einem daran befestigbaren doppelachsigen Vorderachsenfahrwerk 43 (Figur 8) und einem daran befestigten einachsigen Vorderachsenfahrwerk 44 (Figur 9). Denn bei Baukränen schwerer Ausführungen überschreitet die Belastung am Zugrohr eine Tonne. Da mehr als eine Tonne vom Gesetzgeber nicht erlaubt ist, kann man ein Zugrohr nicht mehr einsetzen. Es'kommt deshalb eine zusätzliche (gebremste) Vorderachsenkonstruktion 43 oder 44 zum Einsatz. Entsprechendes gilt für andere Arbeitsvorrichtungen, wie Langrohrgeschütze etc. (siehe oben).Figures 8 and 9 show this in the transport direction of the folded Crane front end of the same with an attachable to it double-axle front axle chassis 43 (Figure 8) and a single-axle front axle chassis 44 attached to it (Figure 9). Because in the case of construction cranes, heavy designs exceed the load on the draw tube is one ton. Because more than one Ton is not allowed by law, you can use a draw tube no longer use. There is therefore an additional one (braked) front axle construction 43 or 44. The same applies to other work devices, such as long-barrel guns etc. (see above).

Der Kran 1 kann, je nach Zugfahrzeug, als Sattelanhänger oder als mehrachsiger Deichselanhänger gezogen werden.The crane 1 can, depending on the towing vehicle, as a semi-trailer or can be pulled as a multi-axle drawbar trailer.

Im einzelnen umfaßt die, vorzugsweise gebremste, Vorderachsenkonstruktion 43 gemäß Figur 8 zwei Achsen 45 und 46 mit Rädern 47 und Federung 55 (Blatt- oder Luftfederung), einem Fahrgestell 48, einem darauf befindlichen Drehkranz 49 (Kugellenkkranz) und einem Aufbaurahmen 50, an dem Laschen 51 zum Anbolzen des Vorderachsenfahrwerks 43 an die Zugeinrichtung 28 der Arbeitsmaschine 1, wie vorliegend des Krans, angebracht sind. An der Schleifplatte 30 der Zugeinrichtung 28 sind Aufnahmevorrichtungen 52 für die Laschen 51 angebracht, und sowohl die Laschen 51 als auch die Aufnahmevorrichtungen 52 sind mit Durchgangslöchern oder Bohrungen 53 für Steckbolzen (nicht dargestellt) versehen. Mittels der Bohrungen oder Durchgangslöcher 53 und der Steckbolzen wird die gesamte Vorderachsenkonstruktion 43 an der Arbeitsvorrichtung 1, im Beispiel am Kran, befestigt.Specifically, the, preferably braked, front axle construction 43 two axles 45 and 46 with wheels according to FIG 47 and suspension 55 (leaf or air suspension), a chassis 48, a slewing ring thereon 49 (ball joint ring) and a mounting frame 50, on which tabs 51 can be bolted on of the front axle chassis 43 to the traction device 28 of the Working machine 1, as in the present case of the crane, are attached. On the grinding plate 30 of the pulling device 28 there are holding devices 52 attached for the tabs 51, and both the Tabs 51 and the receiving devices 52 are also included Through holes or bores 53 for socket pins (not shown). By means of the holes or through holes 53 and the socket pin becomes the entire front axle construction 43 on the working device 1, in the example on Crane, attached.

In Fig. 9 ist eine - ebenfalls bevorzugt gebremste - einachsige Vorderachsenkonstruktion 44 im bereits an der Arbeitsvorrichtung 1, vorliegend am Kran, befestigten Zustand gezeigt. Diese ist, abgesehen von der nur einzigen Achse 54 und der daraus resultierenden Modifikation, im übrigen so ausgebildet wie die Vorderachsenkonstruktion 43 der Figur 8, so daß insoweit auf deren Beschreibung Bezug genommen wird.9 is a - also preferably braked - uniaxial Front axle construction 44 already on the working device 1, shown here on the crane, attached state. This is, apart from the only axis 54 and the resulting modification, otherwise designed like the front axle construction 43 of FIG. 8, so that in this respect to the description of which reference is made.

Die Vorderachsenkonstruktion 43, 44 ist mittels einer Zugdeichsel 56 an ein Zugfahrzeug ankuppelbar.The front axle construction 43, 44 is by means of a drawbar 56 can be coupled to a towing vehicle.

Als Alternative kann die Befestigung der Vorderachsenkonstruktion mittels einer Sattelkupplung am Sattelzapfen 31 erfolgen; bei dieser Konstruktion ist eine Doppelachse 45, 46 unbedingt erforderlich. Die Sattelkupplung ersetzt dann auch den Drehkranz 49, da die Drehbewegung über die Schleifplatte 30 bzw. den Sattelzapfen 31 erfolgt.As an alternative, the front axle construction can be attached by means of a fifth wheel coupling on the saddle pin 31; in this construction, a double axis 45, 46 is essential required. The fifth wheel then also replaces the slewing ring 49, since the rotational movement via the grinding plate 30 or the saddle pin 31 takes place.
