The bogies (4, 5) form a travel chassis movable into position below the crane underframe (1) and there secured to it. A cross-member can be secured to each bogie, pivoting in a vertical plane, and coupled to the other bogie via a ball-and-socket bearing. The cross-members can be of triangular section. The underframe can be supported on the bogies by devices (13) adjustable for height.

Description

Turmdrehkran mit RaupenfahrwerkTower crane with crawler chassis

Die Erfindung bezieht sich auf einen Tunadrehkran mit Raupenfahrwerk bestehend aus durch Querträger verbundene RauPenschiffe.The invention relates to a tuna slewing crane with a crawler track Consists of RauP ships connected by cross beams.

Es sind bereits Turmdrehkräne bekannt, an deren Untergestell zwei oder mehrere Raupenschiffe befestigt sind, um den Kran unabhängig von der Schiene im aufgebauten Zustand von einem Ort zum anderen fahren zu können. Diese Krone weisen jedoch den Nachteil auf, daß jeder Kran mit extra Raupenschiffen ausgerüstet sein muß, was-zu höheren Herstellungskosten führt.There are already tower cranes known, on the base of two or several caterpillars are attached to the crane independently of the rail to be able to drive from one place to another when set up. This crown wise however, the disadvantage that each crane can be equipped with extra caterpillar ships must, which leads to higher manufacturing costs.

Zur Vermeidung dieses Nachteils hat man versucht, die feste Montage der Raupenschiffe dadurch zu umgehen, daß seitwärts an dem Untergestell des Krans mit Antrieben versehene Raupenschiffe abnehmbar montiert sind. Hierdurch wird zwar erreicht, daß nicht jeder Kran eigene Raupenschiffe benötigt; dies Lösung hat jedoch den Nachteil, daß die Montage umständlich ist, da fiir die auf einem LKW herantransportierten Raupenschiffe zur Montaye ein extra Kran erforderlich ist. Soll der Kran auf einen Platz gefahren werden, auf dem seitlich wenig Raum ist, wird zudem die Demon-tage erschwert, wenn nicht gar unmöglich gemacht.To avoid this disadvantage, attempts have been made to use the fixed assembly to bypass the caterpillars by moving sideways on the undercarriage of the crane caterpillar ships provided with drives are removably mounted. This is true achieved that not every crane needs its own caterpillar ships; however, this solution has the disadvantage that the assembly is cumbersome, since they are transported on a truck Crawler ships to the Montaye an extra crane is required. Should the crane be on one In addition, dismantling is required to drive space where there is little space to the side made difficult, if not impossible.

Der Erfindung liegt die Aufgabe zugrunde einen Turmdrehkran im aufgebauten Zustand mittels abnehmbaren Raupen zu transportieren, wobei die Montage bzw. Demontage der Raupenschiffe unabhängig von den räumlichen Gegebenheiten durchführbar ist.The invention is based on the object of a tower crane in the built-up State to be transported by means of removable caterpillars, with assembly and disassembly the caterpillar ships can be carried out regardless of the spatial conditions.

Erfindungsgemäß wird diese Aufgabe durch die in dem Hauptanspruch entha1t+nen Merkmale ge1öt.According to the invention, this object is achieved by in the main claim Contains features required.

Weitere Ausgestaltungen der Erfindung sind in den Unteransprüchen enthalten Die mit der Erfindung erzielbaren Vorteile bestehen darin, daß die Raupenschiffe unabhängig von den räumlichen Gegebenheiten von dem Kran getrennt werden können. Ein weiterer Vorteil besteht darin, daß die Raupenschiffe selbständig zu einem nächsten Kran gefahren werden können, ohne daß ein Verladen auf einen LKW erforderlich ist.Further refinements of the invention are set out in the subclaims The advantages that can be achieved with the invention are that the caterpillar ships can be separated from the crane regardless of the spatial conditions. Another advantage is that the caterpillars can move independently to a next one Crane can be driven without loading it onto a truck is required.

Im folgenden wird die Erfindung anhand der beigefügten Zeichnung beispielhaft erläutert. Es zeigen: Fig. 1 einen Turmderhkran mit fest montiert Krantransportraupe; Fig. 2 die Krantransportraupe in Draufsicht; Fig. 3 die Krantransportraupe in Seitenansicht; Fig. 4 einen Querschnitt eines Raupenschiffes mit Höhenverstellvorrichtung und Befestigungsvorrichtung; Fig. 5 einen Querschnitt des Querträgergalenkes und Fig. 6 eine Detailzeichnung des hochklappbaren Stützfußes.In the following the invention is exemplified with reference to the accompanying drawing explained. 1 shows a tower crane with a permanently mounted crane transport caterpillar; 2 shows the crane transport caterpillar in plan view; 3 shows the crane transport caterpillar in side view; 4 shows a cross section of a caterpillar ship with a height adjustment device and a fastening device; FIG. 5 shows a cross section of the cross member joint and FIG. 6 shows a detailed drawing of the foldable support leg.

An dem Untergestell 1 eines Turmdrehkranes sind 4 Stütz-3 füße befestigt, zwischen deren die Krantransportraupe 2 an Holmen des Untergestelles 1 befestigt ist. Die Krantransportraupe 2 besteht aus zwei über Querträger 6, 7 miteinander verbundene Raupenschiffe 4, 5, die je einen Antriebsmotor 8, 9 besitzen und einem Aggregat 10. Ein Querträger 6 ist vertikal schwenkbar mit dem einen Raupenschiff 4 und der andere Querträger 7 vertikal schwenkbar mit dem Raupenschiff 5 verbunden.4 support feet are attached to the underframe 1 of a tower crane, between which the crane transport caterpillar 2 is attached to the spars of the underframe 1 is. The crane transport caterpillar 2 consists of two cross members 6, 7 with one another connected caterpillar ships 4, 5, each having a drive motor 8, 9 and one Unit 10. A cross member 6 is vertically pivotable with the one caterpillar ship 4 and the other cross member 7 are connected to the crawler ship 5 in a vertically pivotable manner.

Die beiden Querträger sind dreieckförmig ausgebildet, wie sich ohne weiteres aus Fig. 2 ergibt. Das freie Ende des Querträgers 6 des Raupenschiffes 4 ist über ein sphärisches Lager 11 an das Raupenschiff 5 und das freie Ende des anderen Querträgers 7 über ein weiteres sphärisches Lager 12 an das Raupenschiff 4 angelenkt. Diese kardanische Verbindung der Raupenschiffe erlaubt es, daß sich diese unabhängig voneinander an Bodenneigungen anpassen können.The two cross members are triangular, as if without further from FIG. 2 results. The free end of the cross member 6 of the caterpillar ship 4 is via a spherical bearing 11 to the caterpillar 5 and the free end of the other cross member 7 via a further spherical bearing 12 to the caterpillar ship 4 hinged. This gimbal connection of the caterpillars allows that can adapt these independently of each other to the slope of the ground.

Zur Herstellung der Verbindung der Krantransportraupe 2 mit dem Untergestell 1 des Krans und zum Senkrechtstellen des Krans in jeder Phase seiner Fahrstrecke sind an den beiden Raupenschiffen 4, 5 je zwei Niveauzylinder 13 befestigt, deren Kolbenstangen 14 die Befestigungsvorrichtungen 15 zur Verbindung mit an Holmen des Untergestells 1 des Krans angeordneten entsprechenden Gegenstücken 16 tragen, wobei die Befestigungsvorrichtungen (15, 16) Schnellkupplungen aufweisen.To establish the connection of the crane transport caterpillar 2 with the underframe 1 of the crane and for vertical positioning of the crane in every phase of its travel route are attached to the two caterpillar ships 4, 5 each two level cylinders 13, whose Piston rods 14, the fastening devices 15 for connection to the spars of the Carry underframe 1 of the crane arranged corresponding counterparts 16, wherein the fastening devices (15, 16) have quick-release couplings.

Falls erforderlich, können zwischen die beiden Raupenschiffe Balastplatten 17, 18 eingehängt werden, die dreipunktgelagert sind.If necessary, ballast plates can be placed between the two caterpillars 17, 18, which are mounted on three points.

Um den Schwerpunkt des Kranes während der Fahrt so tief wie möglich zu halzen, um die Gefahr das Umkippens auf ein Minimum zu reduzieren, ist das an dem Gegenauslager befindliche Gegengewicht auf das Untergestell 1 des Krans absenkbar.To keep the center of gravity of the crane as low as possible while driving Halving to reduce the risk of tipping over to a minimum is on the counterweight located on the counterweight can be lowered onto the underframe 1 of the crane.

Nachdem die Krantransportraupe 2 mit dem Untergestell 1 des Krans verbunden und der Kran mittels der Niveauzylinder 13 angehoben worden ist, werden die Stützfüße 3 des Krans hydraulisch hochgeklappt. Der Kran ist nun fahrbereit. After the crane transport caterpillar 2 with the underframe 1 of the crane connected and the crane has been raised by means of the level cylinder 13 the support legs 3 of the crane folded up hydraulically. The crane is now ready to go.
