Description
Die Erfindung bezieht sich auf einen Wippkran, dessen Ausleger durch zwei Kreislenker derartig geführt ist, daß. die Last sich beim Wippen auf einer Waagerechten bewegt. Erfindungsgemäß wird nun vorgeschlagen, den Spitzenausleger mit der AuslegerroUe durch den vorderen Lenker hindurchschlagen zu lassen, so daß die Last über den vorderen Lenker drehpunkt hinaus- weit nach hintenThe invention relates to a luffing crane whose boom is supported by two circular links is performed in such a way that. the load moves on a horizontal plane when rocking. According to the invention it is now proposed that the fly jib with the boom roller to let through the front handlebar, so that the load on the front Handlebar pivot point far to the rear
xo durchgewippt und beliebig zwischen den beiden Lenkerdrehpunkten abgesetzt werden kann. Um dabei in jeder Lage einen genügenden Hebelarm zum Wippen zu erhalten, ist die Lastseilrolle unterhalb der Verbindungslinie der beiden oberen Lenkerdrehpunkte angeordnet. Der Umschlag vom Schiff zum Eisenbahnwagen oder zur Laderampe kann hierdurch in einfachster Weise erfolgen, ohne daß man den Kran drehen muß.xo can be rocked through and placed anywhere between the two handlebar pivot points can. In order to have a sufficient lever arm for rocking in every position, the rope pulley is below the connecting line of the two upper handlebar pivot points. The transshipment from the ship to the railroad car or to the loading ramp can be done in the simplest way without turning the crane got to.
Der Vorschlag, mit dem Spitzenausleger durch einen Lenker hindurchzuschlagen, ist bereits früher in Verbindung mit einer Fähre gemacht worden. Man kam bei. dieser Ausführung jedoch mit dem Spitzenausleger nicht über die senkrechte Stellung hinaus, in welcher er -beim weiteren Zurückwippen frei nach unten pendelnd hängenblieb.The suggestion to punch through a handlebar with the fly jib is has been made earlier in connection with a ferry. One came at. this version but with the luffing jib not beyond the vertical position in which he - when rocking back further, remained hanging freely swinging downwards.
Bei einem anderen Kran mit waagerecht liegendem Spitzenausleger ist zwar die Schnabelrolle bis kurz hinter den Drehpunkt des vorderen Lenkers 'einziehbar, der Spitzenausleger kann aber nicht durch den vorderen Lenker hindurchschlagen.Another crane with a horizontally lying jib has the beak pulley Retractable to just behind the pivot point of the front link, the fly jib but cannot penetrate the front handlebar.
Bei dem neuen Kran ist dagegen der Spitzenausleger in allen Lagen zwangläufig geführt und kann genau zu einer bestimmten Absetzstelle selbst bis in die Nähe des hinteren Lenkerdrehpunktes bewegt werden. Die zugehörige Abbildung zeigt ein Ausführungsbeispiel des Erfindungsgegenstandes im Aufriß. With the new crane, however, the luffing jib is inevitable in all positions guided and can be guided to a specific deposition point even up to the vicinity of the rear Handlebar pivot point are moved. The corresponding figure shows an exemplary embodiment of the subject matter of the invention in elevation.
ι ist das nach vorn offene Bortal, auf dem der Ausleger 2 durch die vorderen, seitlich am Ausleger angeordneten Kreislenker 3 und den hinteren Kreislenker 4 geführt wird. Das Lastseil ist über die AuslegerroUe 5 oder 6 und die Lenkerdrehpunkte 7 und 8 zum Windwerk 9 geführt. Das Wippwerk 10 und das Wippausgleichgewicht 11 greifen am vorderen Lenker an. Durch die Wippbewegung des Auslegersystems kann die Last aus der äußersten Stellung I durch das offene Portal bis in die innerste Stellung II gewippt werden.ι is the Bortal open to the front, on which the boom 2 through the front, laterally on the boom arranged circular control arm 3 and the rear circular control arm 4 is guided. The load rope is via the boom 5 or 6 and the link pivot points 7 and 8 to the winch 9 led. The luffing mechanism 10 and the luffing balance weight 11 grip the front Handlebar on. Due to the luffing movement of the boom system, the load can be taken from the outermost Position I can be rocked through the open portal to the innermost position II.
