Description

Die Erfindung bezieht sich auf einen Wippkran für waagerechten Lastwippweg, der eine die Seilablenkrolle tragende, durch eine Verbindung mit dem Ausleger in bezug auf den Ausleger und das Krangerüst bewegliche Schwinge aufweist. Ihr Wesen besteht darin, daß die die Seilablenkrolle tragende ,Schwinge von zwei Lenkern getragen wird. Hierdurch wird vor allem der Vorteil einer besseren. Angleichung des Lastwippwegs an eine horizontale Gerade als bei den bekannten Wippkranen erreicht, die nicht ein Kurvenstück zur Verschiebung der Seilablenkrolle aufweisen. Ein weiterer Vorteil des Erfindungsgegenstandes besteht darin, daß man die Höhe der Aufbauten über dem Kranhaus, welche die mit der Seilablenkrolle versehene Schwinge tragen, herabsetzen kann, selbst dann, wenn man beim Wippen geringe Neigungen des Auslegers herbeiführen will, die man bisher im Hinblick auf die Notwendigkeit eines Ausgleichs großer Seillängen vermeiden mußte. Man kann sogar ohne ein über dem Kranhaus befindliches Gerüst auskommen, ohne hierdurch einen Wippweg zu erhalten, der von einer horizontalen Geraden wesentlich abweicht.The invention relates to a luffing crane for horizontal load luffing path, the one the rope deflection pulley supporting, by a connection with the boom with respect to the Has boom and the crane frame movable rocker. Their essence is that the swing arm carrying the pulley is carried by two links. Through this first of all, the benefit of a better one. Alignment of the load luffing path to a horizontal one Just as achieved with the known luffing cranes, which do not have a curved piece for moving the rope deflection roller. Another advantage of the subject matter of the invention is that the height of the superstructures above the crane house, which carry the rocker arm provided with the rope deflection roller, can lower itself then, if you want to bring about slight inclinations of the boom when luffing, the has been avoided so far in view of the need to compensate for long pitches had to. You can even get by without a scaffold located above the crane house, without thereby obstructing a luffing path obtained, which deviates significantly from a horizontal straight line.

Die Abbildung veranschaulicht ein Ausführungsbeispiel der Erfindung.
Der Ausleger 1 ist um die Achse 2 drehbar, die im Obergurt eines Gerüstes gelagert ist. Die die Seüablenkrolle 4 tragende Schwinge 3 ist ihrerseits von zwei Kreislenkern 8, 9 und 8"j ga getragen, deren Fußpunkte 9, ψ am Obergurt des Gerüstes gelagert sind, in dem die Wippachse 2 des Auslegers 1 gelagert ist. Die Kreislenkerfußpunkte 9, ga sind nur etwas über dem Dach des Führerhauses 6 angeordnet. Die Bewegung des Auslegers 1 wird mittels des Lenkers 10 auf das Gelenkviereck 8> 8") 9, 9a übertragen. Am Ausleger r ist ein Seil 11 befestigt, das über eine um die Achse 5 drehbare Rolle geführt ist und das Gegengewicht 12 zum Ausgleich des Auslegereigengewichts trägt.The figure illustrates an embodiment of the invention.
The boom 1 can be rotated about the axis 2, which is mounted in the top flange of a scaffolding. The Seüablenkrolle 4-supporting rocker arm 3 is supported in turn by two circular arms 8, 9 and 8 "j ga, the base points 9, ψ on the upper flange of the framework are mounted, in which the rocker axle 2 is mounted the boom. 1 the Kreislenkerfußpunkte 9, g a are arranged only slightly above the roof of the driver's cab 6. The movement of the boom 1 is transmitted by means of the link 10 to the four-bar linkage 8> 8 ″) 9, 9 a . A rope 11 is attached to the boom r, which is guided over a roller which can be rotated about the axis 5 and which carries the counterweight 12 to compensate for the boom's own weight.

Die am Krangerüst drehbar gelagerten Kreislenker 8, 9 und 8a, ga können so kurz bemessen sein, daß die Höhe der gesamten Seilablenkrolleneiiirichtung nur sehr gering wird. Über dem Kranhaus 6 befindet sich kein besonderes Gerüst.The circular links 8, 9 and 8 a , g a rotatably mounted on the crane frame can be made so short that the height of the entire Seilablenkrolleeiiirrichtung is only very small. There is no special scaffolding above the crane building 6.
