Description

Die vorliegende Erfindung betrifft einen Kran mit den Merkmalen des Oberbegriffs des Anspruchs 1.The present invention relates to a crane having the features of the preamble of claim 1.

Im Stand der Technik sind viele verschiedene Lösungen zur Realisierung des Verlaufes der wenigstens einen Schlauchleitung (im Folgenden auch kurz "Schlauchverlauf") im Bereich des Übergangs von der Kransäule zum ersten Kranarm bekannt.Many different solutions for realizing the course of the at least one hose line (hereinafter also referred to as "hose run") in the region of the transition from the crane column to the first crane arm are known in the prior art.

Bei einer ersten Lösung erfolgt der Schlauchverlauf zwischen Kransäule und erstem Kranarm von einer außen an der Kransäule montierten Anschlussstelle zu einer an einer Außenseite des ersten Kranarms angeordneten Anschlussstelle.In a first solution, the hose path between the crane column and the first crane arm takes place from a connection point mounted on the outside of the crane column to a connection point arranged on an outer side of the first crane arm.

Bei einer zweiten Lösung befindet sich die Anschlussstelle an der Kransäule an der vom ersten Kranarm abgewandten Seite der Kransäule. Der Schlauchverlauf erfolgt an der Außenseite der Kransäule entlang über das erste Gelenk zu einer Anschlussstelle, die sich an der Oberseite des ersten Kranarms befindet und/oder die wenigstens eine Schlauchleitung passiert das erste Gelenk seitlich in dessen unterem Bereich und verläuft dann nach oben zu einer an der Unterseite des ersten Kranarms angeordneten Anschlussstelle.In a second solution, the connection point on the crane column is located on the side of the crane column facing away from the first crane arm. The course of the hose takes place on the outside of the crane pillar via the first joint to a connection point located at the top of the first crane arm and / or the at least one hose line passes laterally in the lower region of the first joint and then runs upward to one the underside of the first crane arm arranged connection point.

Diese Schlauchführungen sind in der Praxis problematisch wegen des Risikos der Beschädigung der wenigstens einen Schlauchleitung, vor allem im Betrieb des Krans.These hose guides are problematic in practice because of the risk of damaging the at least one hose line, especially in the operation of the crane.

Aufgabe der Erfindung ist es, bei einem gattungsgemäßen Kran die Gefahr der Beschädigung der wenigstens einen Schlauchleitung zu reduzieren.The object of the invention is to reduce the risk of damage to the at least one hose line in a generic crane.

Diese Aufgabe wird durch einen Kran mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a crane having the features of claim 1.

Bei der Erfindung weist der Kran eine um eine vertikale Achse drehbar an einem Grundgestell angeordnete Kransäule und einen über ein erstes Gelenk schwenkbar an der Kransäule montierten ersten Kranarm auf. Wenigstens eine Schlauchleitung führt von einer ersten Anschlussstelle an der Kransäule oder dem Grundgestell zu einer zweiten Anschlussstelle in oder an einem zum ersten Gelenk nahen Bereich des ersten Kranarmes. Durch eine Schwenkbewegung des Kranarms relativ zur Kransäule kommt es zu einer Vergrößerung oder Verkleinerung des Abstandes zwischen der ersten und der zweiten Anschlussstelle. Die bei einer Verkleinerung des Abstandes überschüssig werdenden Abschnitte der wenigstens einen Schlauchleitung sind im Inneren des ersten Kranarmes angeordnet.In the invention, the crane has a crane column which is arranged rotatably about a vertical axis on a base frame and a first crane arm which is mounted pivotably on the crane column via a first joint. At least one hose leads from a first connection point on the crane column or the base frame to a second connection point in or on a region of the first crane arm which is close to the first joint. By a pivoting movement of the crane arm relative to the crane column, there is an increase or decrease in the distance between the first and the second connection point. The sections of the at least one hose line that become excess when the distance is reduced are arranged in the interior of the first crane arm.

Durch den gewählten Schlauchverlauf ergibt sich eine kompakte und straffe Führung der wenigstens einen Schlauchleitung zwischen der Kransäule und dem ersten Kranarm.Due to the selected hose path results in a compact and tight leadership of at least one hose between the crane column and the first crane arm.

Vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen definiert.Advantageous embodiments of the invention are defined in the dependent claims.

Bei der Ausbildung des Krans als Knickarmkran, wird der erste Kranarm häufig als Haupt- oder Hubarm und der zweite Kranarm als Knickarm bezeichnet. Der zweite Kranarm kann eine oder mehrere teleskopierbare Auslegerverlängerungen tragen.In the design of the crane as articulated crane, the first crane arm is often referred to as the main or lifting arm and the second crane arm as articulated. The second crane arm may carry one or more telescopic boom extensions.
