Description
Die Erfindung betrifft einen Mastkran mit Last- und Gegenausleger und besteht im wesentlichen' darin, daß der Lastausleger und der Gegen ausleger um .einen gemeinsamen Zapfen drehbar und unabhängig voneinander einstellbar sind.The invention relates to a mast crane with load and counter jib and consists in essential 'in the fact that the load boom and the counter boom to .a common Spigots are rotatable and adjustable independently of each other.
In der Zeichnung ist eine Ausführungsform des vorliegenden Mastkrans für Bauzwecke veranschaulicht, welcher Bauteile verschiedener Art, z. B. Querträger (Binder) und Längsträger (Pfetten) eines eisernen Dachstuhles, zu heben gestattet.In the drawing is an embodiment of the present mast crane for construction purposes illustrates which components of different types, e.g. B. Cross member (binder) and Longitudinal beams (purlins) of an iron roof truss, allowed to be lifted.
Der Mast 4 steht auf einer Plattform 3, die mittels des mit dem Mast gleichachsigen Zapfens 2 auf einem fahrbaren Wagen 1 drehbar ist. Die Rollen 5, 6 am oberen Ende des Mastes nebst Seil oder Kette 7 und Winde 8 dienen zum Heben der Querträger oder Binder. Außerdem sind zum Heben der Längsträger oder Pfetten ein Lastausleger 9 und ein Gegenausleger 11 um einen gemeinsamen Zapfen 10 im Mast drehbar und unabhängig voneinander einstellbar, indem sie durch Rollen 16 und Seil 17 untereinander und weiterhin mit einer Winde 18 auf der Plattform verbunden sind, so daß die Ausladung des Lastauslegers 9 beliebig geändert werden kann. Zum Heben der dem Lastausleger 9 zugehörigen Last dienen Rollen 12,13 nebst Seil 14 und Winde 15.The mast 4 stands on a platform 3, which is coaxial with the mast by means of Pin 2 is rotatable on a mobile carriage 1. The rollers 5, 6 at the top of the mast together with rope or chain 7 and winch 8 are used to lift the crossbeams or trusses. Also are for lifting the longitudinal beams or purlins have a load boom 9 and a counter boom 11 around a common one Pin 10 in the mast rotatable and independently adjustable by by rollers 16 and rope 17 with each other and continue with a winch 18 on the Platform are connected, so that the extension of the load boom 9 changed at will can be. Rollers 12, 13 are used to lift the load associated with the load boom 9 together with rope 14 and winch 15.
Der Gegenausleger 11 ist sonach durch die Seil- oder Kettentrume 17, 14- mit der Plattform 3 kraftschlüssig verbunden und infolgedessen wird, solange diese Trume ebenso wie das die Last tragende Trum des Seiles oder der Kette lotrecht verlaufen, die Resultierende aller auf den Mast wirkenden Kräfte durch den Drehzapfen 10 gehen und lotrecht verlaufen. Dadurch wird eine Beanspiuchung des Mastes auf Biegung mit Sicherheit verhütet, so daß der Mast 4 und die Plattform 3 nebst Wagen 1 verhältnismäßig leicht gebaut sein können. Der Gegenausleger 11 kann mit der Plattform 3 auch unmittelbar durch ein Seil oder eine Kette 20 kraftschlüssig verbunden sein.The counter jib 11 is therefore through the Rope or chain strands 17, 14- with the platform 3 frictionally connected and as a result, as long as these dreams as well as that the load-bearing strand of the rope or chain run perpendicular, the resultant of all forces acting on the mast go through the pivot 10 and run perpendicular. This prevents the mast from being subjected to bending stress with certainty, so that the mast 4 and the platform 3 together with the carriage 1 are built relatively easily could be. The counter jib 11 can with the platform 3 also directly through a Rope or a chain 20 be positively connected.
