Description
Bei einem Stripperkran wird die Traverse, auf der die Strippeinrichtung und deren Drehwerk angeordnet ist, in einem an der Katze befestigten Gerüst geführt, das aus vier Längsholmen· besteht, die untereinander durch Querstreben gitterartig verbunden sind. Diese Verstrebungen sind unerwünscht. Sie wirken nicht nur unschön, sondern verteuern auch das Gerüst. Außerdem zwingen sie dazu, die Querschnittsfläche des Gerüstes so großIn the case of a stripper crane, the traverse on which the stripping device and its slewing mechanism are arranged is guided in a frame attached to the trolley, which consists of four longitudinal spars, which are connected to one another in a grid-like manner by cross struts. These struts are undesirable. Not only do they look unattractive, they also make the scaffolding more expensive. They also force in addition, the cross-sectional area of the framework is so large
ίο zu wählen, daß alle auf der Traverse unterzubringenden Einrichtungen innerhalb dieser Querschnittsfläche liegen.'Dies zwingt aber z.B. bei hydraulisch betriebenen Stripperwerken, bei denen die hydraulische Einrichtung einen erheblichen Raum einnimmt, zu einer wesentlichen Vergrößerung des Gerüstquerschnittes und damit zu einem höheren Gewicht. Außerdem werden damit die Sichtverhältnisse für den Kranführer verschlechtert. Die Erfindung schafft einen Stripperkran, der von' diesen Mangeln frei ist. Hier wird1 das Führungsgerüst für die Traverse erfindungsgemäß von zwei od'er mehr Säulen gebildet, die lediglich an ihren Unterenden miteinander verbunden sind. Da diese Säulen aber wegen der fehlenden Verstrebung erheblichen Biegungsbeanspruchungen ausgesetzt sind1, wenn die Zange gegen ein Hindernis fährt, würde die durch den Fortfall der Verstrebung erzielte Gewichtsersparnis durch die dann erforderliche Verstärkung der Säulen wieder verlorengehen.ίο to choose that all devices to be accommodated on the traverse are within this cross-sectional area. However, in the case of hydraulically operated stripper works, in which the hydraulic device takes up a considerable amount of space, this forces the scaffold cross-section to be increased significantly and thus to a higher weight. In addition, the visibility for the crane operator is impaired. The invention provides a stripper crane which is free from these shortcomings. Here, the guide frame for the crosshead according to the invention is formed by two od'er more uprights 1, which are joined together only at their lower ends. Since these columns are exposed to considerable bending stresses due to the lack of bracing 1 when the tongs hit an obstacle, the weight savings achieved by eliminating the bracing would be lost again through the reinforcement of the columns that would then be required.
Die Erfindung schlägt deshalb "weiterhin vor, die Traverse so auszubilden, daß sie die Säulen führend umfaßt. Auf diese Weise lassen sich die Biegungsmomente in erträglichen Grenzen halten, so daß man mit verhältnismäßig leichteni Säulen auskommen.· kann. Bei der erfindungsgemäßen Ausbildung durchsetzen die Säulen also die Traverse, wie es in der Zeichnung dargestellt ist, die ein Ausführungsbeispiel des Erfindungsgedankens wiedergibt. The invention therefore "also proposes to design the traverse so that it guides the pillars includes. In this way, the bending moments can be kept within tolerable limits, so that one can get by with relatively light columns. In the training according to the invention enforce the columns so the traverse, as shown in the drawing, the one embodiment of the concept of the invention reproduces.
Die Katze 1 mit der Hubwinde 2' ist auf dem Kranträger 3 verfahrbar und weist zwei hier als breitflanschige I-Träger ausgebildete Säulen 4 auf, die an ihren Unterenden durch einen Bügel 5 (Abb. 2) miteinander verbunden sind. Bei Anwendung von vier Säulen erhält der Bügel 5 die in Abb. 3 wiedergegebene Form. In beiden Fällen erhält der Kranführer durch diese Aussparungen eine gute Sicht.The trolley 1 with the hoist winch 2 'is on the Crane girder 3 can be moved and has two columns 4, which are designed here as wide-flanged I-girders, which are connected to each other at their lower ends by a bracket 5 (Fig. 2). When using four pillars, the bracket 5 is given the shape shown in Fig. 3. In both cases the crane operator receives a good view through these recesses.
Die Säulen 4 dienen als Führung für die Traverse 6, welche die Strippeinrichtung 7 trägt und gleichzeitig als Führerkanzel ausgebildet sein· kann.The columns 4 serve as a guide for the traverse 6, which carries the stripping device 7 and can be designed as a driver's cab at the same time.
An Stelle von I- oder anderen Profilen können auch Rohre für die Säulen verwendet werden, die in Abb. 3 mit 8 bezeichnet sind.Instead of I or other profiles, tubes can also be used for the columns, which are denoted by 8 in Fig. 3.
