Description

Die Erfindiung betrifft einen Wippkran mit nach zwei Seiten durchschlagendem, die Last seitlich am Krangerüst vorbeiführendem Ausleger, der unter Benutzung eines hinter dem. Ausleger gelagerten, gegenläufig zu ihm angetriebenen, eine Lastseilurnlenkrolle tragenden· Schwinghebels die Last anhebt. Dadurch, daß bei Kranen dieser Art der Schwinghebel nicht gleichachsig zum Ausleger sitzt und das Lastseil unmittelbar von der Schwinghebelrolle zur Spitzenrolle geführt ist, ergeben sich bei mehrfacher Aufhängung der Last verschiedene freie Seillängen beim Schwenken. Um diesen Nachteil zu vermeiden, werden beim Gegenstand der Erfindung die Lastseile von der Auslegerkopfrolle, die pendelnd gelagert ist, über eine im Ausleger ebenfalls pendelnd gelagerte Zwischenrolle zu der Rolle am Schwinghebel -geführt, der gleichachsig mit dem Ausleger gelagert ist.The invention relates to a luffing crane with a break through on two sides Load on the side of the crane frame passing jib, using a behind to the. Cantilever mounted, driven in the opposite direction, carrying a load rope swivel pulley Rocker arm lifts the load. The fact that in cranes of this type the rocker arm is not on the same axis as the boom sits and the load rope is led directly from the rocker arm pulley to the top pulley If the load is suspended multiple times, there are different free rope lengths when panning. In order to avoid this disadvantage, in the subject matter of the invention, the load ropes are removed from the jib head pulley, which is mounted pendulum, via an intermediate roller also pendulum mounted in the boom to the roller on the rocker arm -guided, which is mounted coaxially with the boom.

Die Zeichnung stellt den Erfindungsgegenstand dar, und zwar zeigt:The drawing represents the subject matter of the invention, namely shows:

Abb. 2 einen. Seitenriß.Fig. Ι an elevation,
Fig. 2 a. Side crack.

Der Ausleger« und der Schwinghebel δ werden durch das Einziehwerk c parallel in entgegengesetzter Richtung bewegt. Das Lastseil ist über zwei pendelnd aufgehängte Seilrollen d, d in der Auslegerspitze zu der Umlenkrolle geführt, die an dem auf der Drehachse des Auslegers α gelagerten Schwinghebel & angeordnet ist.The boom and the rocker arm δ are moved in parallel in opposite directions by the retraction mechanism c. The load rope is guided via two suspended rope pulleys d, d in the jib tip to the deflection pulley, which is arranged on the rocker arm & mounted on the axis of rotation of the jib α.

Das Hubwerk kann auf dem Schwinghebel aufgebaut werden.The hoist can be built on the rocker arm.
