Abstract

The crane has a stand (2) on its own chassis, on which an extendable boom (3) can turn. The stand, without the ballast boom, is on another vehicle (4), independent of the road vehicle and of smaller dimensions. The vehicle has a ballast arrangement. On the free end there are support beams carrying a leg. The small vehicle can be mounted on and released from the road vehicle, and when removed from it, can travel and manoeuvre independently.

Description

Die Erfindung betrifft einen Kran, insbesondere einen Montagekran für den Innenbereich.The invention relates to a crane, in particular a Assembly crane for indoor use.

Aus der DE-U 91 14 464.7 ist ein als selbst straßenfahrfähiges Spezialfahrzeug ausgebildeter Schwerlastkran bekannt. Dieser besteht aus einem kastenförmigen Träger, der mit einen vergleichsweise großen Durchmesser aufweisenden Rädern und diesen zugeordneten Stoßdämpfern versehen ist und auf dem ein Drehkranz aufgenommen ist, auf dem ein einen ausfahrbaren Ausleger tragender Ständer aufgenommen ist. Dieser trägt auch einen Antriebsmotor, der als Antriebsaggregat und gleichzeitig als Ballasteinrichtung fungiert. Der Träger ist mit quer zur Fahrzeugachse ausfahrbaren Stützbalken versehen.From DE-U 91 14 464.7 is as self roadworthy special vehicle trained Heavy duty crane known. This consists of one box-shaped carrier that compares with a large diameter wheels and these assigned shock absorbers is provided and on the one Slewing ring is included, on which an extendable Boom supporting stand is added. This carries also a drive motor that acts as a drive unit and also acts as a ballast facility. The carrier is with support bars that can be extended transversely to the vehicle axis Mistake.

Der Nachteil eines straßenfahrfähigen Krans der aus der DE-U 91 14 464.7 entnehmbaren Art besteht darin, daß der große, zur Bereitstellung der Straßenfahrfähigkeit erforderliche Aufwand nur bei den Fahrten auf der Straße genutzt wird. Bei den in der Regel einen viel längeren Zeitraum als die Straßenfahrten einnehmenden Kranarbeiten im Innenbereich liegt der genannte Aufwand brach und wird praktisch nicht benutzt, da hier eine einfache Manövrierbarkeit ausreicht. Ein weiterer Nachteil ist darin zu sehen, daß bei einem straßenfahrfähigen Fahrzeug ein Motor benötigt wird, der Abgase erzeugt, die bei Innenarbeiten unerwünscht sind. Zu dem kann sich hierdurch eine Beschränkung des Schwenkraums ergeben. Außerdem ergeben sich eine vergleichsweise große Höhe und Breite. Die Durchfahrt durch enge und niedere Tore etc. ist mit derartigen Fahrzeugen daher nicht möglich. Diese eignen sich dementsprechend nicht für den Innenbereich.The disadvantage of a roadworthy crane from the DE-U 91 14 464.7 removable type is that the large, to provide roadworthiness effort required only when driving on the road is being used. Usually a much longer one Period as the crane work taking up the road trips indoors, the effort mentioned is and will be wasted practically not used because here a simple one Maneuverability is sufficient. Another disadvantage is to see that in a roadworthy vehicle an engine is needed that generates exhaust gases at Indoor work is undesirable. To that can this results in a limitation of the swivel space. In addition, there is a comparatively large height and Width. The passage through narrow and low gates etc. is therefore not possible with such vehicles. This Accordingly, they are not suitable for indoor use.

Ein weiterer Nachteil der bekannten Anordnung ist darin zu sehen, daß die Stützbalken zur Vermeidung einer Beeinträchtigung der Lenkbarkeit der großen, das Gestell flankierenden Räder nur quer zur Fahrzeuglängsachse ausfahrbar sein können. Dies ist jedoch gerade im Innenbereich ungünstig, da hier von vergleichsweise schmalen Wegen auszugehen ist, so daß der seitliche Ausfahrweg beschränkt ist.Another disadvantage of the known arrangement is that to see that the support beams to avoid a Impaired the steerability of the large, the frame flanking wheels only transversely to the vehicle's longitudinal axis can be extendable. However, this is precisely in Indoor area unfavorable, because of comparative here narrow paths to go out, so that the side Exit path is limited.

Aus der DE-A 20 17 058 ergibt sich ein Kran mit einem lösbar auf einem als Straßenfahrzeug ausgebildeten Unterwagen aufnehmbaren, eigenständigen Oberwagen, der einen Kranaufbau aufweist. Hierbei handelt es sich jedoch um einen Schwerlastkran, bei dem nicht nur der Unterwgen, sondern auch der den Kranaufbau enthaltende Oberwagen als straßenfahrfähige Spezialfahrzeuge ausgebildet sind, die separat voneinander auf Fahrt gehen müssen, um das im Straßenverkehr zulässige Gesamtgewicht nicht zu überschreiten. Beim Unterwagen handelt es sich um ein Spezialfahrzeug mit einem Drehkranz und mit Abstützeinrichtungen. Der auf dem Drehkranz aufnehmbare Oberwagen besitzt selbst keine Dreheinrichtung und keine Abstützeinrichtung. Der Oberwagen ist daher zwar im vom Unterwagen abgenommenen Zustand als einfaches Hebezeug verwendbar, nicht jedoch als drehbarer Montagekran. Auch eine universelle Verwendbarkeit des Unterwagens ist in Folge seines Charakters als Spezialfahrzeug mit Drehkranz und Abstützeinrichtungen nicht möglich. DE-A 20 17 058 results in a crane with a releasably on a trained as a road vehicle Undercarriage, removable, independent superstructure, the has a crane structure. However, this is a heavy-duty crane, in which not only the undercarriage, but also the superstructure containing the crane structure as roadworthy special vehicles are trained that have to go separately from each other in order to Total weight not permissible on the road exceed. The undercarriage is a Special vehicle with a slewing ring and with Supports. The one that can be picked up on the slewing ring The superstructure itself has no rotating device and none Support device. The superstructure is therefore in the Undercarriage removed condition as a simple hoist usable, but not as a rotating assembly crane. Also universal use of the undercarriage is in As a result of its character as a special vehicle with a slewing ring and supports are not possible.

Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung, einen Kran zu schaffen, der zusammen mit einem normalen Straßenfahrzeug als Autokran verwendbar ist und der unabhängig vom Straßenfahrzeug einen Montagekran für den Innenbereich ergibt.Based on this, it is therefore the task of present invention to provide a crane which together with a normal road vehicle as a truck crane can be used and is independent of the road vehicle results in an assembly crane for indoor use.

Diese Aufgabe wird durch den Anspruch 1 gelöst. Hiermit kommt ein Kran mit einem selbst nicht straßenfahrfähigen Wagen in Vorschlag, der kleinere Abmessungen als ein durch einen LKW gebildetes Straßenfahrzeug aufweist und zur Bildung eines Autokrans lösbar auf dem zugeordneten Straßenfahrzeug aufnehmbar ist und der im vom Straßenfahrzeug abgenommenen Zustand unabhängig hiervon verfahrbar und manövrierbar ist, wobei der Wagen ein eine Ballastanordnung enthaltendes Gestell mit lenkbaren, vorderen und hinteren Schwerlast-Lauforganen aufweist und mit abnehmbren, schwenkbar angeordeten, an ihrem freien Ende jeweils ein Standbein tragenden Stützbalken versehen ist, und wobei auf dem Gestell ein Drehkranz aufgenommen ist, der einen ballastauslegerlosen Ständer trägt, auf dem ein ausfahrbarer Ausleger schwenkbar aufgenommen ist.This object is solved by claim 1. Herewith comes a crane with one that is not even roadworthy Carriage in proposal of smaller dimensions than one has road vehicle formed by a truck and to form a mobile crane releasably on the assigned Road vehicle is recordable and in the Road vehicle removed condition regardless of this is movable and maneuverable, the car being a one Frame containing ballast arrangement with steerable, has front and rear heavy duty running elements and with removable, swivel-mounted, at their free Provide a supporting beam with a supporting leg at the end is, and wherein a turntable is added to the frame is on a stand without a ballast boom which an extendable boom is pivotally received.

Mit diesen Maßnahmen werden die Nachteile der bekannten Anordnungen vollständig vermieden.Der selbst nicht straßenfahrfähige Wagen enthält alles, was ein Montagekran für den Innenbereich benötigt und nichts, was hierfür hinderlich wäre. Allein der Wagen mit seinem Aufbau ergibt daher einen Montagekran für den Innenbereich, der separat vom zugeordneten Straßenfahrzeug verwendbar ist. Dieses kann daher bei abgenommenem Wagen separat eingesetzt werden. Andererseits wird als Straßenfahrzeug auch kein Spezialfahrzeug benötigt, was die separate Verendbarkeit des Straßenfahrzeugs noch fördert. Die dem Wagen zugeordnete Stützeinrichtung ist nicht nur für eine separate Verwendbarkeit als Montagekran förderlich, sondern ermöglicht in vorteilhafter Weise auch ein Absetzen des Wagens vom Straßenfahrzeug mittels der Stützeinrichtung. Eine Rampe etc. ist daher nicht unbedingt erforderlich. Da das Gestell des Wagens im transportfähigen Zustand gegenüber dem Straßenfahrzeug nicht bewegt wird und der auf dem Gestell aufgenommene Ständer keine eigene Ballasteinrichtung aufweist, kommt die erfindungsgemäße Anordnung in jedem Fall mit einem vergleichsweise geringen Platz aus. Ein Schwenkraum für eine Ballastanordnung ist nicht erforderlich. Dies gilt sowohl bei separater Verwendung als Montagekran im Innenbereich als auch bei Verwendung als Autokran. Dennoch sind in jedem Fall eine hohe Tragfähigkeit und Kippsicherheit gewährleistet, da der erforderliche Ballast in das Gestell integriert ist. Die schwenkbaren Stützbalken können in vorteilhafter Weise diagonal gestellt werden. Sofern der Montagekran schräg in eine Hallenwegkreuzung gestellt wird, können die Stützbalken dabei in die sich kreuzenden Wege hineinragen, was eine große Stützlänge ermöglicht. Beim Transport können die Stützbalken einfach abgenommen werden, so daß sich eine kompakte, auf einem normalen LKW aufnehmbare Anordnung ergibt. Der vom Transportfahrzeug abgesetzte Montagekran benötigt in Folge seiner geringen Breite und Höhe nur eine vergleichsweise geringe lichte Durchfahrtsbreite und -höhe, was im Innenbereich außerordentlich wichtig ist. Außerdem ist sichergestellt, daß der erfindungsgemäße Kran in Folge der nicht benötigten Straßenfahrfähigkeit ohne eingebautes Antriebsaggregat auskommt, so daß ein bei Innenarbeiten unerwünschter Abgasausstoß unterbleibt.With these measures, the disadvantages of the known Orders completely avoided, but not himself roadworthy wagon contains everything a Assembly crane for indoor use and nothing needed would be a hindrance to this. The car alone with his Construction therefore results in an assembly crane for the Interior, which is separate from the assigned Road vehicle is usable. This can therefore at removed car can be used separately. On the other hand, as a road vehicle, none Special vehicle needs what the separate applicability of the road vehicle still promotes. The car assigned support device is not only for one separate usability as an assembly crane, but also advantageously enables one Lower the car from the road vehicle using the Support device. There is therefore no ramp etc. absolutely necessary. Since the frame of the car in transportable condition compared to the road vehicle is not moved and the one recorded on the frame Stand does not have its own ballast facility the arrangement according to the invention in any case with a comparatively small space. A swivel space for a ballast arrangement is not required. this applies both when used separately as an assembly crane in the Indoors as well as when used as a mobile crane. Nevertheless, are in any case a high load capacity and Guaranteed tipping safety as the required Ballast is integrated into the frame. The swiveling Support beams can advantageously be diagonal be put. If the assembly crane slants into a The support beams can be placed at the intersection of the Hallenweg protrude into the intersecting paths, what a large support length enables. During transport, the Support beams can be easily removed so that there is a compact arrangement that can be accommodated on a normal truck results. The assembly crane set apart from the transport vehicle only needs due to its small width and height a comparatively small clear passage width and -height, which is extremely important indoors. It also ensures that the invention Crane due to the unneeded road driving ability manages without a built-in drive unit, so that a undesirable exhaust emissions are avoided when working inside.

Der in Figur 1 dargestellte Kran enthält einen auf einem hydraulisch drehbaren Drehkranz 1 aufgenommenen, ballastauslegerlosen Turm oder Ständer 2, an den ein mittels eines Hydraulikaggregats schwenkbarer Ausleger 3 angelenkt ist. Dieser kann mehrere, durch Knickgelenke verbundene Abschnitte enthalten, die ihrerseits jeweils mehrere teleskopartig ineinander angeordnete Stücke enthalten können, die durch Hydraulikaggregate ausfahrbar sind. In der Transportstellung sind die Abschnitte auf die kleinste Länge verkürzt und so gegeneinander geknickt, daß sich ein Paket ergibt. Der Kran ist auf einem zugeordneten Wagen 4 montiert, der ein auf Lauforganen, hier auf mit einer Schwerlastbereifung versehenen Vorder- und Hinterrädern 5 aufgenommenes Gestell 6 aufweist. Dieses besitzt die Vorder- und Hinterräder 5 übergreifende Aufleger 7 und ein zwischen diesen angeordnetes, stufenartig nach unten abgesetztes, mittleres Tiefbatt 8, auf dem der Drehkranz 1 montiert ist. Dieser ist, wie am besten aus Figur 2 erkennbar ist, zentral angeordnet. Die Aufleger 7 und vorzugsweise auch das Tiefbett 8 sind als massive Stahlplatten ausgebildet, die als dem Kran zugeordnete Ballastgewichte fungieren. Anstelle der Räder könnten auch die Lauforgane bildende Schwerlastraupen vorgesehen sein, um die Flächenbelastung möglichst klein zu halten.The crane shown in Figure 1 contains one on a hydraulic rotatable slewing ring 1 incorporated, ballast-free tower or Stand 2, to which a pivotable by means of a hydraulic unit Boom 3 is articulated. This can be multiple, through articulated joints contain connected sections, which in turn each contain several telescopically nested pieces can contain through Hydraulic units are extendable. They are in the transport position Sections shortened to the smallest length and kinked against each other, that there is a package. The crane is on an assigned carriage 4 mounted, one on running elements, here with heavy-duty tires provided front and rear wheels 5 received frame 6. This has the front and rear wheels 5 cross overlap 7 and an arranged between them, stepped down, medium low-lying 8 on which the slewing ring 1 is mounted. This is how am is best seen from Figure 2, arranged centrally. The trailer 7 and preferably also the deep bed 8 are designed as solid steel plates, that act as ballast weights assigned to the crane. Instead of the wheels could also be provided heavy duty caterpillars forming the running elements, in order to keep the area load as small as possible.

Zur Erhöhung der Kippsicherheit des Wagens 4 sind Stützbalken 9 vorgesehen, die wagenseitig jeweils um eine stehende Achse schwenkbar gelagert sind und an ihrem freien Ende ein auf den Untergrund ausetzbares Standbein 10 tragen. Zur schwenkbaren Lagerung der Stützbalken 9 sind im Bereich der Ecken des Tiefbetts 8 Scharnierlager 11 vorgesehen, auf denen die Stützbalken 9 lösbar aufnehmbar sind. Dies ermöglicht eine einfache Abnahme der Stützbalken 9, sofern diese für einen Manövriervorgang etc. hinderlich sein sollten. Die Stützbalken 9 bestehen aus mehreren, teleskopartig ineinander angeordneten und dementsprechend ein- und ausfahrbaren Stücken, so daß sich eine große Gesamtlänge erreichen läßt. Die am freien Ende der Stützbalken 9 jeweils vorgesehenen Standbalken 10 können einfach als Zylinderaggregate ausgebildet sein, deren ausfahrbare Stange mit einem auf dem Untergrund ausetzbaren Teller versehen ist. Die Standbeine 10 sind am jeweils zugeordneten Stützbalken 9 lösbar festlegbar, was eine einfache Austauschbarkeit ermöglicht, worauf im Zusammenhang mit Figur 3 noch näher eingegangen werden wird.Support beams 9 are provided to increase the safety against tipping of the carriage 4 provided, which can be pivoted on the carriage side in each case about a standing axis are stored and at their free end an exposed to the ground Wear leg 10. For the pivotable mounting of the support beams 9 are in Area of the corners of the low bed 8 hinge bearing 11 provided on which the support beams 9 are releasably receivable. This enables easy Removal of the support beams 9, provided that they are used for maneuvering etc. should be a hindrance. The support beams 9 consist of several telescopically arranged and accordingly in and extendable pieces, so that a large overall length can be achieved. The standing beams 10 provided in each case at the free end of the support beams 9 can simply be designed as cylinder units, the extendable Rod is provided with a plate that can be deployed on the surface. The Legs 10 can be detached from the associated support beam 9 definable, which enables easy interchangeability, what in In connection with Figure 3 will be discussed in more detail.

In der Fahrstellung sind die Stützbalken 9 so gestellt, daß sie sich in Wagenlängsrichtung erstrecken, wie in Figur 2 unten angedeutet ist. Zur Aufnahme der Stützbalken 9 in der Fahrstellung ist der Wagen 4 gestellseitig mit in Längsrichtung von den Scharnierlagern 11 abgehenden Nischen 12 versehen, in welche die Stützbalken 9 in der Fahrstellung einschwenkbar sind, sodaß die Wagenbreite hierdurch nicht vergrößert wird. In Längsrichtung können die Stützbalken 9 über die Wagenenden auskragen. In der Arbeitsstellung sind die Stützbalken 9 sternförmig ausgestellt, wie in Figur 2 oben angedeutet ist. Das Verschwenken der Stützbalken 9 kann manuell vorgenommen werden. In der ausgestellten Stellung können die Stützbalken dabei jeweils mittels einer am Wagengestell 6 angelenkten Stützstrebe 13 gesichert sein. Es wäre aber auch denkbar, zum Verschwenken der Stützbalken 9 Stellzylinder vorzusehen. Ebenso können die Stützbalken 9 manuell oder mittels eines Stellzylinders teleskopierbar sein.In the driving position, the support beams 9 are set so that they are in Extend the longitudinal direction of the carriage, as indicated in FIG. 2 below. For Receiving the support beams 9 in the driving position, the carriage 4 is on the frame side with niches extending in the longitudinal direction from the hinge bearings 11 12 provided, into which the support beams 9 can be pivoted in the driving position are, so that the carriage width is not increased. Longitudinal can the support beams 9 protrude over the car ends. In the In the working position, the support beams 9 are shown in a star shape, as in FIG. 2 is indicated above. The pivoting of the support beams 9 can be done manually be made. In the displayed position, the support beams can each by means of a support strut 13 articulated on the carriage frame 6 be secured. But it would also be conceivable to pivot the support beams 9 positioning cylinders to be provided. The support beams 9 be telescopic manually or by means of an actuating cylinder.

Die Räder 5 sind, wie aus Figur 2 erkennbar ist, zur Erzielung einer großen Wendigkeit nicht an durchgehenden Achsen aufgenommen, sondern als Lenkräder ausgebildet. Dabei ist jedem Rad 5 eine kurze, nicht durchgehende Achse 14 zugeordnet, die auf einem vereinfacht dargestellten, am zugehörigen Aufleger 7 aufgenommenen Lagerbock um eine stehende Achse schwenkbar gelagert ist. Jedem Rad 5 kann ein Antriebsmotor, z.B. ein elektrischer oder hydraulischer Antriebsmotor, zugeordnet sein. Das zugehörige Versorgungsaggregat, bei hydraulischem Antrieb die Hydraulikpumpe, kann mittels eines Motors, vorzugsweise eines Gasmotors, der aus einer Gasflasche mit Gas versorgbar ist, das rückstandslos oder -arm verbrennt, antreibbar sein. Zur Aufnahme des Motors samt eventuell vorgesehener Gasflasche und des Versorgungsaggregats bzw. der -aggregate kann ein dem Wagen 4 zugeordneter Beistellwagen 26 vorgesehen sein, wie Figur 1 zeigt. Stromverbraucher können über Kabel an das Stromnetz angeschlossen werden. Der Beistellwagen 26 kann dabei eine geeignete Verbindungs- und/oder Umspanneinrichtung etc. enthalten. Mit Hilfe der genannten oder einer separaten Pumpe können auch die übrigen Hydraulikaggregate, beispielsweise zum Drehen, Auf- und Abschwenken sowie Ein- und Ausfahren des Auslegers 3 etc. mit Druckflüssigkeit versorgt werden.As can be seen from FIG. 2, the wheels 5 are large in order to achieve them Maneuverability is not recorded on continuous axles, but as Steering wheels trained. Each wheel 5 is a short one, not assigned continuous axis 14, which simplifies on a illustrated, on the associated support 7 received bracket a standing axis is pivotally mounted. Each wheel 5 can Drive motor, e.g. an electric or hydraulic drive motor, be assigned. The associated supply unit, for hydraulic The hydraulic pump can be driven by means of a motor, preferably one Gas engine that can be supplied with gas from a gas bottle, the burns residue-free or low, be drivable. To accommodate the Engine including any gas bottle and the Supply unit or units can be a 4 associated trolley 26 may be provided, as shown in Figure 1. Electricity consumers can be connected to the mains via cables become. The trolley 26 can be a suitable connection and / or Transformer etc. included. With the help of the mentioned or The other hydraulic units, For example, for turning, swiveling up and down as well as swiveling in and out Extending the boom 3 etc. can be supplied with hydraulic fluid.

Die genannten, den Rädern 5 zugeordneten Antriebsmotoren ergeben eine selbstfahrende Anordnung. Zur Lenkung kann eine Vielweglenkeinrichtung vorgesehen sein, mittels der die einzlen aufgehängten Räder 5 einzeln oder paarweise unabhängig voneinander einstellbar sind. Die Vielweglenkeinrichtung kann elektronisch gesteuert sein. Hierzu kann ein geeigneter Rechner beigestellt oder auf dem Wagen 4 angeordnet sein.The mentioned drive motors assigned to the wheels 5 result in a self-driving arrangement. A multi-way steering device can be used for steering be provided, by means of which the individual suspended wheels 5 individually or can be set independently in pairs. The Multi-way steering device can be electronically controlled. For this, a suitable computer provided or arranged on the carriage 4.

Im dargestellten Beispiel ist der Wagen 4, wie Figur 2 anschaulich erkennen läßt, nicht selbstfahrend, sondern als mittels einer Zugmaschine zieh- bzw. schiebbarer Anhänger ausgebildet. Den Rädern 5 zugeordnete Antriebsmotoren kommen dabei in Wegfall. Die Achsen 14 sind hierbei über an einem Schwenkhebel angeordnete Lenker 15 mit einem um einen Zugnagel 16, der eine stehende Achse bildet, schwenkbaren, mittleren Deichselträger 17 verbunden. Beim Schwenken des zugeordneten Deichselträgers 17 werden somit beide hiermit verbundenen Räder 5 entsprechend eingeschlagen. Der Wagen 4 ist hier symmetrisch aufgebaut, d.h. dem vorderen und dem hinteren Räderpaar ist jeweils ein Deichselträger 17 zugeordnet. An einem der Deichselträger 17 ist eine Zugdeichsel 18 angebracht. Diese ist abnehmbar und bei Bedarf am anderen Deichselträger 17 anbringbar.In the example shown, the carriage 4 is, as can clearly be seen in FIG leaves, not self-propelled, but as pulling or by means of a tractor sliding trailer trained. 5 assigned to the wheels Drive motors are eliminated. The axes 14 are here arranged on a pivot lever 15 with one Pull nail 16, which forms a standing axis, pivotable, middle Drawbar carrier 17 connected. When swiveling the assigned Drawbar carrier 17 are thus both wheels 5 connected to it struck accordingly. The carriage 4 is constructed symmetrically here, i.e. the front and rear pair of wheels is one Drawbar carrier 17 assigned. On one of the drawbar carriers 17 is one Drawbar 18 attached. This is removable and if necessary on other drawbar carrier 17 attachable.

Der mittels der Zugdeichsel 18 bewerkstelligbare Einschlag des jeweils zugeordneten Radpaares wird mittels einer Steuereinrichtung auf das jeweils andere Radpaar übertragen. Hierzu sind die beiden Deichselträger 17 mit diametral einander gegenüberliegenden, am Gestell 6 abgestützten Zylindern 19 verbunden, die mittels einer hydraulischen Steuerleitung so miteinander verknüpft sind, daß der durch die Zugdeichsel 18 bewirkte Einschlag des mit der Zugdeichsel 18 verbundenen Deichselträgers 17 automatisch auf den gegenüberliegenden Deichselträger 17 übertragen wird. Die beiden Zylinderaggregate 19 fungieren dabei als Tast- und Stellzylinder eines geschlossenen Steuerkreises. Selbstverständlich ist es auch denkbar, an beiden Deichselträgern 17 eine Deichsel anzubringen und hiermit individuell zu manövrieren. In diesem Fall sind die Zylinderaggregate 19 der vorstehend beschriebenen Nachführeinrichtung außer Betrieb zu setzten.The impact that can be achieved by means of the drawbar 18 assigned wheel pair is controlled by a control device on the transmit each other pair of wheels. For this purpose, the two drawbar supports 17 with diametrically opposed, supported on the frame 6 Cylinders 19 connected by means of a hydraulic control line are linked to each other that that caused by the drawbar 18 Impact of the drawbar carrier 17 connected to the drawbar 18 automatically transferred to the opposite drawbar carrier 17 becomes. The two cylinder units 19 act as feeler and actuating cylinders a closed control circuit. Of course it is conceivable to attach a drawbar to both drawbar supports 17 and hereby to maneuver individually. In this case, the cylinder units are 19th the tracking device described above out of operation set.

Sofern anstelle der Räder 5 Raupen vorgesehen sind, können die oben geschilderten Maßnahmen hinsichtlich Antrieb und Lenkbarkeit auch hierfür gelten. Die Raupen sind jedoch zweckmäßig paarweise auf einem zugeordneten Träger aufgenommen, der um einen gemeinsamen Zapfen drehbar ist.If 5 caterpillars are provided instead of the wheels, the above described measures with regard to drive and steerability also for this be valid. However, the caterpillars are expediently in pairs on one assigned carrier added to a common pin is rotatable.

Zur Bildung eines Autokrans und/oder zum Transport des oben beschriebenen Krans kann dieser samt seinem Wagen 4 auf einem LKW aufgenommen werden. Diese Situation liegt der Figur 3 zugrunde. Dabei ist auf dem Fahrzeugrahmen 20 des als ganzes mit 21 bezeichneten Lastkraftwagens ein lösbar festlegbarer Zwischenrahmen 22 positioniert, auf dem der Wagen 4 aufgenommen ist. Der Zwischenrahmen 22 ist durch ineinander eingreifende und gegeneinander verriegelbare Halteklauen 23 auf dem Fahrzeugrahmen 20 lösbar verankert. Der Wagen 4 ist durch Riegel 24 und Spanner 25 auf dem Zwischenrahmen 22 lösbar verankert.To form a mobile crane and / or to transport the above Crane described can this together with his car 4 on a truck be included. This situation is the basis of Figure 3. It is on the vehicle frame 20 of the whole designated 21 Truck positioned a releasably fixable intermediate frame 22 on which the carriage 4 is included. The intermediate frame 22 is through interlocking and mutually lockable holding claws 23 releasably anchored to the vehicle frame 20. The carriage 4 is bolted 24 and tensioner 25 releasably anchored on the intermediate frame 22.

Die Abmessungen des Wagens 4 sind kleiner als die entsprechenden Abmessungen des LKWs 21, wodurch unerwünschte Überstände vermieden werden. Bei Versuchen hat sich ein Wagen mit einer Spurbreite von 140 cm, einer Breite von 180 cm und einer Länge von 400 cm bewährt. Dennoch werden bei einer der Figur 3 zugrundeleigenden Verwendungsweise eine vergleichsweise große, durch den LKW 21 diktierte Durchfahrsbreite und - höhe benötigt. In der der Figur 1 zugrundeliegenden, abgesetzten Verwendungsweise kommt man dagegen mit einer kleineren, allein vom Wagen 4 vorgegebenen Durchfahrtsbreite und -höhe aus.The dimensions of the carriage 4 are smaller than the corresponding ones Dimensions of the truck 21, thereby avoiding unwanted protrusions become. During trials, a wagon with a track width of 140 cm a width of 180 cm and a length of 400 cm. Yet are one in the use of FIG. 3 comparatively large passage width dictated by the truck 21 and - height needed. In the basis of Figure 1, offset In contrast, use comes with a smaller one, only from Car 4 predetermined passage width and height from.

Sofern der LKW 21 über eigene, seitlich ausfahrbare Stützbalken verfügt, können die Stützbalken 9 des Wagens 4 in der der Figur 3 zugrundeleigenden, aufgesetzten Verwendungsweise abgenommen sein. Hierzu sind die Stützbalken 9 lösbar gelagert. Sofern der LKW 21 nicht über eigene Stützbalken oder nur über zu kurze Stützbalken verfügt, können die Stützbalken 9 des Wagens 4 auch in der der Figur 3 zugrundeliegenden, aufgesetzten Verwendungsweise beibehalten werden. In diesem Fall ist es jedoch zweckmäßig, die bei der abgesetzten Verwendungsweise gemäß Figur 1 Verwendung findenden, in der Länge an die Höhe des Wagens 4 angepaßten und dementsprechend vergleichsweise kurzen Standbeine 10 gegen längere auszutauschen, sodaß auch bei der aufgesetzten Verwendungsweise gemäß Figur 3 ein zuverlässiger Bodenkontakt der unteren Stützteller der Standbeine 10 schnell herstellbar ist. Dementsprechend sind die Standbeine 10, wie weiter oben schon ausgeführt wurde, austauschbar angeordnet.If the truck 21 has its own, laterally extendable support beams, can the support beams 9 of the carriage 4 in the figure 3 underlying, put-on mode of use have been accepted. For this purpose, the support beams 9 are detachably mounted. Unless the truck 21 over own support beams or only too short support beams, can Support beam 9 of the carriage 4 also in the one on which FIG. 3 is based, applied use are retained. In this case it is however expedient, according to the remote use Figure 1 used, in length to the height of the carriage 4th adapted and accordingly comparatively short pillars 10 to be exchanged for longer ones, so that it can also be used 3 a reliable ground contact of the lower Support plate of the legs 10 can be produced quickly. Are accordingly the legs 10, as already explained above, are interchangeable arranged.

Während der Fahrt ist der Kranausleger 3, wie oben schon angedeutet wurde, zu einem Paket zusammengelegt. Der Ständer 2 wird dabei in eine Drehstellung gebracht, in welcher sich das genannte Paket etwa in Fahrzeuglängsrichtung erstreckt. Hiedurch ist sichergestellt, daß in der Breite vergleichsweise wenig Platz benötigt wird. Dies ist hier ohne weiteres möglich, da sich der auf seinem Wagen 4 verbleibende Kran mit seiner Achse etwa im mittleren Bereich der LKW-Ladefläche befindet. Sofern der LKW 21 samt Zwischenrahmen anderweitig benötigt werden oder die von einer Anordnung gemäß Figur 3 benötigte Durchfahrtsbreite oder -höhe nicht zur Verfügung stehen sollte, wird der Wagen 4 samt Kran abgenommen und gemäß Figur 1 mit seinen Lauforganen, hier inform der Räder auf dem Untergrund abgestellt, wobei dann die gegenüber der LKW-Breite kleinere Wagenbreite und eine um die LKW-Ladehöhe kleinere Durchfahrtshöhe ausreichen. Anstelle eines LKW der Figur 3 entnehmbaren Art kann zum Transport auch ein LKW-Anhäger, zweckmäßig in Tieflader-Bauweise, Verwendung finden.While driving, the crane boom 3 is, as already indicated above was merged into one package. The stand 2 is in one Brought rotary position, in which the said package is approximately in Vehicle longitudinal direction extends. This ensures that in the Comparatively little width is required. This is straightforward here possible because the crane remaining on his wagon 4 with his Axis is located approximately in the middle of the truck bed. If the Truck 21 including intermediate frame are otherwise required or by an arrangement according to Figure 3 required passage width or height should not be available, the wagon 4 including crane removed and according to Figure 1 with its running elements, here inform the Wheels parked on the ground, then the opposite of the truck width smaller wagon width and a smaller truck loading height Sufficient headroom. Removable instead of a truck of Figure 3 Type can also be a truck trailer for transport, conveniently in low-loader construction, Find use.
