Description
Die Erfindung bezieht sich auf einen Wagendrehkran mit den Führersitz und den Ausleger tragender, im völligen Kreise drehbarer Plattform. Es sind Krane dieser Art bekannt, bei denen die Kransäule in dauernder Verbindung mit dem vorderen Fahrgestell ist, dessen Räder durch getrennte Elektromotoren angetrieben werden. Die Drehung erfolgt dann dadurch, daß die Laufräder in entgegengesetzter Richtung gedreht werden. Durch diese dauernde Verbindung ist dem Kran eine ganz bestimmte Bahn vorgeschrieben. Außerdem wird durch die Anordnung der Lenkräder zur Kransäule die Standfestigkeit beim Drehen vermindert.The invention relates to a slewing crane with the driver's seat and the Cantilever-bearing platform that can be rotated in a complete circle. They are cranes like that known, in which the crane column in permanent connection with the front chassis is whose wheels are driven by separate electric motors. The rotation then takes place in that the running wheels rotated in the opposite direction. This permanent connection means that the crane is given a very specific path. In addition, the arrangement of the steering wheels to the crane column reduces the stability when turning.
Es sind auch Krane dieser Art bekannt, bei denen zwischen Lenkrädern und Plattform ein ein- und ausrückbares Getriebe vorgesehen ist, derart, daß die DrehbewegungThere are also known cranes of this type, in which between the steering wheels and the platform an engageable and disengageable gear is provided, such that the rotary movement
ao der Plattform entweder unabhängig von der Lenkbewegung des Fahrzeuges erfolgen kann oder in Abhängigkeit davon. Bei den bekannten Kranen dieser Art ist die Anordnung dabei so getroffen, daß keine feste Beziehung zwischen den Stellungen des Steuerrades und den Lenkrädern und den Stellungen des Auslegers besteht, so daß der Kranführer die Empfindung für die Richtung verliert, in welcher die Lenkräder des Wagens stehen.ao the platform can either be done independently of the steering movement of the vehicle or depending on it. In the known cranes of this type, the arrangement taken in such a way that there is no fixed relationship between the positions of the steering wheel and the steering wheels and the positions of the boom, so that the crane operator loses sense of the direction in which the steering wheels of the car are facing.
Die Erfindung will diesen Nachteil vermeiden und dafür sorgen, daß der Fahrer, wenn die zum Steuern dienenden Lenkräder mit der Plattform gekuppelt sind, aus der Richtung, in welcher der Ausleger zeigt, auch ohne weiteres erkennt, in welcher Richtung der Kran fährt. Infolgedessen ist der Fahrer leicht imstande, Hindernisse in der Bahn des Kranwagens zu vermeiden.The invention aims to avoid this disadvantage and to ensure that the driver, when the steering wheels used for steering are coupled to the platform, from the Direction in which the boom is pointing also easily recognizes in which direction the crane moves. As a result, the driver is easily able to clear obstacles in the path of the Avoid crane trucks.
Gemäß der Erfindung ist das Getriebe derart ausgebildet, daß bei Abhängigkeit von Lenkradgetriebe und Plattform, also Auslegerdrehung, der Ausleger sich stets im gleichen Winkel; dreht wie die Steuerräder.According to the invention, the transmission is designed such that when dependent on Steering wheel gear and platform, so boom rotation, the boom is always at the same angle; turns like the steering wheels.
Die Erfindung ist durch die Zeichnung beispielsweise dargestellt, und zwar zeigt Abb. ι einen Aufriß,The invention is illustrated by the drawing, for example, namely shows Fig. Ι an elevation,
Abb. 2 eine Unteransicht,Fig. 2 is a bottom view,
Abb. 3 einen Schnitt nach Linie 3-3 in Abb. 2,Fig. 3 a section along line 3-3 in Fig. 2,
Abb. 4 einen Teilgrundriß (unter Weglassung der Plattform).Fig. 4 is a partial plan (omitting the platform).
Abb. 5 bis 8 sind im kleinen Maßstabe gehaltene schematische Darstellungen, welche die Grenze der abhängigen Bewegung von Steuerrädern und Ausleger zeigen.Figs. 5 through 8 are small-scale schematic representations, which show the limit of the dependent movement of steering wheels and boom.
