Description

Die Erfindung betrifft ein Kransystem zur Zusammenstellung eines Krans, insbesondere eines Montagekrans für den Innenbereich.The invention relates to a crane system for assembling a crane, especially an assembly crane for indoor use.

Aus der DE 196 02 972 A1, die dem Oberbegriff des Anspruchs 1 entspricht, ist ein solches Kransystem einschließlich einem Montagekran bekannt, bei dem der Kranaufbau drehbar auf einem einteiligen Wagengestell aufgenommen ist. Der komplette Kran kann auf ein Transportfahrzeug aufgesetzt werden. Dabei ergeben sich eine vergleichsweise große Gesamthöhe sowie ein vergleichsweise hohes Gesamtgewicht.From DE 196 02 972 A1, which corresponds to the preamble of claim 1, such a crane system including an assembly crane is known, in which the Crane body is rotatably mounted on a one-piece carriage frame. The complete crane can be placed on a transport vehicle. This results in a comparatively large overall height and a comparatively high total weight.

Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung, einen Kran zu schaffen, der ein vergleichsweise großes Einsatzfeld hat.Proceeding from this, it is therefore the object of the present invention to create a crane that has a comparatively large field of application.

Diese Aufgabe wird mit den im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmalen gelöst. This object is with the specified in the characterizing part of claim 1 Features resolved.

Bei auf dem Transportfahrzeug aufgenommenem, den Kranaufbau tragendem Wagengestellteil ergibt sich ein Autokran. Bei vom Transportfahrzeug abgenommenem, den Kranaufbau enthaltendem Wagengestellteil kann unter Verwendung dieses Wagengestellteils und der dazugehörigen, weiteren Wagengestellteile ein den Kranaufbau enthaltender Wagen zusammengestellt werden wobei sich ein unabhängig vom Transportfahrzeug verfahr- und manövrierbarer Kran ergibt, der für vergleichsweise geringe Durchfahrtshöhen und/oder- breiten geeignet ist. Gleichzeitig ist das Transportfahrzeug frei für andere Verwendungen. Durch die erfindungsgemäßen Maßnahmen wird in vorteilhafter Weise sichergestellt, dass nicht der gesamte Wagen auf dem Transportfahrzeug aufgenommen werden muss, sondern nur das die den Kranaufbau enthaltende Aufnahmeeeinrichtung bildende, fahrwerkslose Gestellteil. Dabei entfällt der der Bodenfreiheit des Wagens entsprechende Abstand zum Transportfahrzeug, was in vorteilhafter Weise auch zu einer vergleichsweise geringen Gesamthöhe des Autokrans führt. Da die übrigen nicht zur Aufnahmeeinrichtung gehörender Wagengestellteile extra transportierbar sind, ergibt sich zudem eine Einsparung an Gewicht und Platz. Es ist daher in vorteilhafter Weise möglich, die Größe des Kranaufbaus selbst zu erhöhen, ohne dass sich eine aus der entsprechenden Vergrößerung des Wagens resultierende Beschränkung ergäbe. When the crane body is picked up on the transport vehicle carrying truck frame part results in a mobile crane. At from Transport vehicle removed, containing the crane superstructure Trolley frame part can be made using this trolley frame part and the associated, additional car frame parts a the crane superstructure Containing wagons are put together with an independent results from the transport vehicle movable and maneuverable crane that for comparatively low clearance heights and / or widths is suitable. At the same time, the transport vehicle is free for other uses. The measures according to the invention are advantageous ensured that not the entire car on the transport vehicle must be included, but only that the crane superstructure containing receiving device forming, chassis-less frame part. The distance corresponding to the ground clearance of the car is omitted to the transport vehicle, which advantageously also leads to a comparatively low overall height of the mobile crane. Because the rest Car frame parts not belonging to the receiving device are transportable, there is also a saving in weight and Place. It is therefore advantageously possible to adjust the size of the To raise the crane superstructure itself, without one from the corresponding enlargement of the car resulting restriction would result.

Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den Unteransprüchen angegeben und aus der nachstehenden Beispielsbeschreibung anhand der Zeichnung näher entnehmbar.Advantageous refinements and practical training of overriding measures are specified in the subclaims and from the example description below using the drawing removable.

Der der Figur 1 zugrundeliegende Kran besitzt einen auf einem Drehkranz 1 aufgenommenen Kranaufbau 2 mit einem ballastauslegerlosen Ständer 3 und einem hieran angelenkten Kranausleger 4, der zweckmäßig aus mehreren, zu einem Paket zusammenlegbaren, hydraulisch ausfahrbaren Abschnitten besteht. Der Drehkranz 1 ist auf einer zugeordneten Aufnahmeplattform einer Aufnahmeeinrichtung 5 montiert, die als massiver, rechteckförmiger Block ausgebildet ist. Der Drehkranz 1 ist dabei, wie Figur 2 zeigt, bezüglich der Längsachse der Aufnahmeeinrichtung 5 außermittig angeordnet, so daß das oben erwähnte, den Kranausleger 4 im zusammengelegten Zustand enthaltende Paket, das sich seitlich des Ständers 3 befindet, etwa mittig gestellt werden kann. The crane on which FIG. 1 is based has one on a slewing ring 1 recorded crane structure 2 with a stand without ballast boom 3 and a crane boom 4 articulated thereon, which expediently several hydraulically extendable collapsible into one package Sections exists. The slewing ring 1 is on an associated Recording platform of a recording device 5 mounted as massive, rectangular block is formed. The slewing ring is 1 here, as Figure 2 shows, with respect to the longitudinal axis of the Recording device 5 arranged off-center, so that the top mentioned, containing the crane boom 4 in the collapsed state Package that is located on the side of the stand 3, approximately in the middle can be.

Die Aufnahmeeinrichtung 5 kann, wie die Figuren 1 und 2 zeigen, in einen Wagen 6 integriert oder, wie aus Figur 3 entnehmbar ist, allein auf ein Transportfahrzeug 7, beispielsweise in Form eines serienmäßigen Lastkraftwagens, aufgesetzt werden. Im ersten Fall ergibt sich ein unabhängig vom Transportfahrzeug 7 verfahr- und manövrierbarer Montagekran, der jedoch nicht straßenfahrfähig ist. Im zweiten Fall ergibt sich ein straßenfahrfähiger Autokran, Insbesondere im Transportzustand wirkt sich dabei die oben erwähnte Außermittigkeit des Drehkranzes 1 vorteilhaft auf die Kippsicherheit aus.The receiving device 5 can, as shown in FIGS. 1 and 2, in integrated a carriage 6 or, as can be seen from FIG. 3, alone on a transport vehicle 7, for example in the form of a standard truck. In the first case results move independently of the transport vehicle 7 and maneuverable assembly crane, but it is not roadworthy. in the The second case is a mobile crane that can be driven on the road, in particular in transport condition, the one mentioned above has an effect Eccentricity of the slewing ring 1 advantageous on the safety against tipping out.

In der Verwendung gemäß Figuren 1 und 2 bildet die Aufnahmeeinrichtung 5 ein mittleres Gestellteil des Wagens 6, dessen Gestell in drei Gestellteile unterteilt ist, die lösbar aneinander festlegbar sind. Am die Aufnahmeeinrichtung 5 bildenden, mittleren Gestellteil sind dementsprechend die äußeren Gestellteile 8 und 9 lösbar festlegbar. In den Figuren 1 und 2 sind die Gestellteile des Wagens 6 aus Gründen der Übersichtlichkeit in einem ungekuppeltem, auseinandergezogenen Zustand dargestellt. Das mittlere, die Aufnahmeeinrichtung 5 bildenden Drehgestellteil ist fahrwerkslos. Die hiermit kuppelbaren äußeren Gestellteile 8 und 9 sind mit als Schwerlastradanordnungen 10 ausgebildeten Fahrwerkselementen versehen. Die fahrwerkslose Ausbildung des die Aufnahmeeinrichtung 5 bildenden Gestellteils stellt sicher, daß dieses, wie Figur 3 anschaulich zeigt, abstandslos auf die zugeordnete Ladefläche des Transportfahrzeugs 7 aufsetzbar ist.In the use according to Figures 1 and 2, the Recording device 5 is a central frame part of the carriage 6, the Frame is divided into three frame parts that can be releasably attached to one another are. On the middle frame part forming the receiving device 5 are accordingly the outer frame parts 8 and 9 detachable fixable. 1 and 2 are the frame parts of the carriage 6 for reasons of clarity in an uncoupled, exploded state shown. The middle, the Receiving device 5 forming bogie part is chassisless. The hereby connectable outer frame parts 8 and 9 are with as Heavy duty wheel assemblies 10 trained chassis elements Mistake. The chassis-less design of the receiving device 5 forming frame part ensures that this, as Figure 3 vividly shows, without a gap on the assigned loading area of the Transport vehicle 7 can be placed.

Das die Aufnahmeeinrichtung 5 bildende Gestellteil ist im Bereich seiner den beiden äußeren Gestellteilen 8 und 9 zugewandten Seitenflächen mit vorzugsweise am unteren Rand angeordneten Anschlußmitteln 11 versehen. Die beiden äußeren Gestellteile 8 und 9 sind im Bereich ihrer dem mittleren Gestellteil zugewandten Seitenflächen mit korrespondierenden, hier ebenfalls am unteren Rand angeordneten Anschlußmitteln 12 versehen. Die Anschlußmittel 11, 12 sind hier als durch vertikal angeordnete Laschen gebildete Lagerböcke ausgebildet, die so gegeneinander versetzt sind, daß sie verzahnungsartig ineinander geschoben werden können. Die genannten Laschen sind mit horizontalen Bohrungen 13 versehen, die so angeordnet sind, daß sich im ineinandergeschobenen Zustand eine fluchtende Durchgangsbohrung ergibt, durch die ein horizontaler Verriegelungsbolzen 14 durchsteckbar ist, wodurch sich eine scharnierartige Kupplung ergibt. Der Verriegelungsbolzen 14 kann manuell oder nach Art von bei Baumaschinen üblichen, sogenannten Schnellkupplungen hydraulisch ein- und ausgerückt werden.The frame part forming the receiving device 5 is in the area his facing the two outer frame parts 8 and 9 Side surfaces preferably arranged at the bottom Connection means 11 provided. The two outer frame parts 8 and 9 are in the area of the middle part of the frame Side surfaces with corresponding ones, here also at the bottom arranged connection means 12 provided. The connection means 11, 12 are here as bearing blocks formed by vertically arranged tabs trained, which are offset so that they can be pushed into each other like gears. The above Tabs are provided with horizontal holes 13, so are arranged that one in the nested state aligned through hole results through which a horizontal Locking bolt 14 can be pushed through, resulting in a hinge-like coupling results. The locking bolt 14 can manually or in the manner of what is known in construction machines Quick couplings can be hydraulically engaged and disengaged.

Die Anschlußmittel 11 des die Aufnahmeeinrichtung 5 bildenden Gestellteils dienen, wie aus Figur 3 entnehmbar ist, auch zur Festlegung der Aufnahmeeinrichtung 3 auf dem Transportfahrzeug 7. Hierzu sind transportfahrzeugseitig mit den Anschlußmitteln 11 korrespondierende Anschlußmittel 12a vorgesehen. Die Verriegelung erfolgt wiederum durch horizontale Verriegelungsbolzen 14. Die ebenfalls durch laschenformige Lagerböcke gebildeten Anschlußmittel 12a sind hier an einem Zwischengestellt 15 befestigt, das auf dem Rahmen 16 des Transportfahrzeugs 7 lösbar festlegbar ist. Hierzu können gegeneineander verriegelbare Halteklauen vorgesehen sein. Der die nach oben vorstehenden Anschlußmittel 12a enthaltende Zwischenrahmen 15 kann dementsprechend schnell vom Transportfahrzeug 7 abgenommen werden, so daß dieses für jede andere Verwendung frei ist.The connection means 11 of the receiving device 5 forming As can be seen from FIG. 3, frame parts also serve for Fixing the receiving device 3 on the transport vehicle 7. For this purpose, the connection means 11 are provided on the transport vehicle side Corresponding connection means 12a are provided. The lock is again done by horizontal locking bolts 14. Die also formed by bracket-shaped bracket 12a are attached here to an intermediate point 15 which is on the Frame 16 of the transport vehicle 7 is releasably fixable. For this locking claws which can be locked against one another can be provided. The the above-mentioned connection means 12a containing Intermediate frame 15 can accordingly quickly from Transport vehicle 7 are removed so that this for each other use is free.

Ebenso ist es denkbar, den Zwischenrahmen 15 samt hierauf aufgenommenem Kran auf einem geeigenten Untergrund, beispielsweise auf dem Boden einer Halle, abzustellen, sofern man mit einem stationären Kran auskommt und kein verfahrbarer Wagen 6 benötigt wird. Der Zwischenrahmen 15 dient sowohl im auf das Transportfahrzeug 7 montiertem Zustand als auch im abgenommenen Zustand, d.h. sowohl beim Autokran als auch beim stationären Kran, zur Aufnahme von hier nicht näher dargestellten Ballastanordnungen. It is also conceivable to place the intermediate frame 15 on it picked up crane on a suitable surface, for example on the floor of a hall, provided you can use a stationary crane gets by and no mobile carriage 6 is required becomes. The intermediate frame 15 serves both in the Transport vehicle 7 assembled state and in the removed Condition, i.e. both with the mobile crane and with the stationary crane, to accommodate ballast arrangements not shown here.

Bei stationärer Anordnung kann auch eine zusätzliche Verankerung am Untergrund vorgesehen sein.In the case of a stationary arrangement, an additional anchoring on Be provided underground.

Der das als Aufnahmeeinrichtung 5 fungierende, mittlere Gestellteil bildende, rechteckförmige Block ist im Bereich seiner Ecken mit weiteren Anschlußmitteln 17 versehen, an denen mit hiermit korrespondierenden Anschlußmitteln 18 versehene Organe anschließbar sind. Die Lagerböcke 17 und 18 sind jeweils mit vertikalen Bohrungen 19 versehen, die. in der Eingriffsstellung eine durchgehende vertikale Bohrung ergeben, durch die ein vertikaler Verriegelungsbolzen 20 durchsteckbar ist, wodurch sich eine scharnierartige Kupplung mit vertikaler Drehachse ergibt.The middle frame part that acts as the receiving device 5 forming, rectangular block is in the area of its corners provided further connection means 17, on which with this corresponding connecting means 18 provided organs can be connected. The bearing blocks 17 and 18 are each vertical Provided holes 19, the. a continuous in the engaged position vertical hole through which a vertical locking bolt 20 can be pushed through, which results in a hinge-like coupling vertical axis of rotation results.

Bei den an den Lagerböcken 17 anschließbaren Organen kann es sich, wie aus Figur 2 erkennbar ist, um mit geeigneten Lagerböcken 18 versehene Stützbalken 21 handeln. Diese sind im angeschlosenen Zustand um die durch den vertikalen Verriegelungsbolzen 20 gebildete, vertikale Achse schwenkbar. Die Stützbalken 21, die zur Erhöhung der Kippsicherheit dienen, sind zweckmäßig teleskopartig verlängerbar und an ihrem vom Lagerbock 18 abgewandten Ende mit einem in vertikaler Richtung einstellbaren Stützfuß 22 versehen, der einen auf den Untergrund aufsetzbaren Stützteller 23 trägt. Zur Bildung des Stützfußes 22 kann zweckmäßig ein Hydraulikaggregat vorgesehen sein, an dessen ausfahrbarer Kolbenstange der Stützteller 23 befestigt ist. Die Stützfüße 21 können sowohl dem fahrbaren Montagekran gemäß Figuren 1 und 2 als auch dem Autokran gemäß Figur 3 als auch einem durch Absetzen des Autokrans gebildeten stationären Kran oben erwähnter Art zur Erhöhung der Kippsicherheit zugeordnet sein. Die Ausfahrbarkeit der Stützfüße 22 gewährleistet dabei eine Anpassung an die erforderliche Stützhöhe. Es wäre aber auch denkbar, die Stützfüße für die einzelnen Einsatzfälle gegeneinander auszutauschen.In the case of the organs which can be connected to the bearing blocks 17, as can be seen from FIG. 2, with suitable bearing blocks 18 provided support beams 21 act. These are in the connected State around the formed by the vertical locking bolt 20 vertical axis swiveling. The support beams 21, which increase the Serve against tipping, are expediently extendable and telescopic at its end facing away from the pedestal 18 with a vertical one Direction adjustable support foot 22 provided one on the Supportable support plate 23 supports. To form the Supporting foot 22 can expediently be provided with a hydraulic unit be attached to the extendable piston rod of the support plate 23 is. The support feet 21 can both the mobile assembly crane according to Figures 1 and 2 as well as the mobile crane according to Figure 3 as well a stationary crane formed by placing the truck crane on top be mentioned to increase the safety against tipping. The Extendibility of the support feet 22 ensures an adaptation to the required support height. But it would also be conceivable to use the support feet exchange for the individual applications.

Im dargestellten Beispiel sind die beiden äußeren Gestellteile 8, 9 des Wagens 6 unterschiedlich lang, wie die Figuren 1 und 2 erkennen lassen. Das kürzere Gestellteil 8 ist als Einachser ausgebildet; d.h. es sind zwei einander gegenüberliegende Fahrwerkselemente 10 vorgesehen. Das längere Gestellteil 9 ist demgegenüber als mit vier Fahrwerkselementen 10 versehener Zweiachser ausgebildet. Dieser besitzt eine vergleichsweise große Ablagefläche und ist hier im Bereich seines vom mittleren Gestellteil abgewandten Endes mit eigenen, quer zur Wagenlängsrichtung ausfahrbaren Stützbalken 24 versehen, die bei Verwendung des Wagens 6, wie in Figur 2 angedeutet ist, zwei direkt am die Aufnahmeeinrichtung 5 bildenden Gestellteil angreifende Stützbalken 21 ersetzen können. An den so nicht benötigten Anschlußmitteln 17 des die Aufnahmeeinrichtung 5 bildenden Gestellteils wird bei der dargestellten Ausführung das längere Gestellteil 9 zusätzlich angekuppelt.In the example shown, the two outer frame parts 8, 9 of the Wagens 6 of different lengths, as shown in Figures 1 and 2 to let. The shorter frame part 8 is designed as a single axle; i.e. it are two mutually opposite chassis elements 10 intended. The longer frame part 9 is in contrast to four Chassis elements 10 provided two-axle. This has a comparatively large storage area and is here in the area its end facing away from the middle part of the frame with its own, across extendable to the longitudinal direction of the support beam 24 provided at Use of the carriage 6, as indicated in Figure 2, two directly engaging on the frame part forming the receiving device 5 Support beam 21 can replace.
