Description
Bei den bekannten Schwimmkranen mit zwei voneinander unabhängigen, als Auslegerkrane ausgebildeten Hebezeugen verschiedener Tragkraft kann das Arbeitsgebiet des Lastorganes für große Lasten nicht vom Lastorgan für kleine Lasten bestrichen werden und umgekehrt, d. h. das Arbeitsgebiet des einen Lastorganes greift nicht in dasjenige des anderen Lastorganes ein. Diese Einrichtung ist mitIn the known floating cranes with two independent, as jib cranes trained hoists of various load capacities can be the work area of the load organ for large loads are not covered by the load organ for small loads and vice versa, d. H. the work area of one load organ does not intervene in that of the other Load organs a. This facility is with
ίο verschiedenen Nachteilen verknüpft. Soll z. B. bei einer solchen Anordnung eine Last mit dem kleinen Haken angehoben werden, die sich im Bereich des großen Hakens befindet, so muß vorher der ganze Schwimmkran gedreht oder verfahren werden, bis dieser in einer solchen Lage ist, daß die Last von dem kleinen Haken erfaßt werden kann. Gemäß vorliegender Erfindung ist nun die Anordnung derart getroffen, daß der Ausleger des einenίο linked to various disadvantages. Should z. B. in such an arrangement a load can be lifted with the small hook, which is in the area of the large hook, the entire floating crane must first be turned or be moved until it is in such a position that the load is removed from the small hook can be detected. In accordance with the present invention, the arrangement is now taken in such a way that the boom of one
ao Hebezeuges ringsum drehbar ist, und daß den Ausleger des anderen Hebezeuges am Untergestell des ersten Hebezeuges angeordnet ist. Bei einer solchen Anordnung beherrscht der eine Haken das Arbeitsgewicht des anderen Hakens vollständig und der letztere wiederum beherrscht einen mehr oder weniger großen Teil des Arbeitsgebietes des ersten Hakens.ao hoist is rotatable all around, and that the The boom of the other hoist is arranged on the underframe of the first hoist. With such an arrangement, one hook controls the working weight of the other Hook completely and the latter in turn dominates a more or less large one Part of the working area of the first hook.
Auf der Zeichnung ist der Gegenstand der Erfindung schematisch veranschaulicht.The subject matter of the invention is illustrated schematically in the drawing.
Fig. ι ist eine Seitenansicht und Fig. 2 eine Stirnansicht.Fig. 1 is a side view and Fig. 2 is an end view.
Auf dem Schwimmkörper α ist exzentrisch die Stützsäule b angeordnet. Letztere trägt oben in bekannter Weise einen drehbaren und, falls erforderlich, auch wippbaren Ausleger c, der so bemessen ist, daß er nur zum Anheben kleinerer Lasten benutzt werden kann. Zum Heben der schweren Lasten dient der Ausleger d, der so an der Stützsäule b angeordnet ist, daß seine Längsachse in Richtung derjenigen des Schwimmkörpers verläuft bzw. mit dieser zusammenfällt. Der Ausleger d kann starr oder wippbar mit der Stützsäule b verbunden sein. In welcher Weise die beiden Hebezeuge c und d im einzelnen gestaltet sind, ist für den Erfindungsgegenstand belanglos.The support column b is arranged eccentrically on the floating body α. The latter carries above in a known manner a rotatable and, if necessary, luffing boom c, which is dimensioned so that it can only be used for lifting smaller loads. To lift the heavy loads, the boom d is used, which is arranged on the support column b that its longitudinal axis runs in the direction of that of the floating body or coincides with this. The boom d can be connected rigidly or rockably to the support column b . The way in which the two hoists c and d are designed in detail is irrelevant to the subject matter of the invention.
