Abstract

Bei einem Ladekran (1) mit wenigstens einem an einem Krangerüst (2) um eine im wesentlichen horizontale Achse (4) verschwenkbaren Auslegerarm (3), wobei an dem gegebenenfalls um eine im wesentlichen vertikale Achse (5) verdrehbaren Krangerüst (2) und dem Auslegerarm (3) ein hydraulisches ZylinderKolbenaggregat (6) zum Verschwenken des Auslegerarmes (3) gelenkig angelenkt ist und wobei beim Beginn der Schwenkbewegung des Auslegerarmes (3) aus der vollkommen eingeschwenkten Lage des Auslegerarmes (3) eine Verschiebung der Anlenkstelle (10) des hydraulischen Zylinder-Kolbenaggregates (6) am Auslegerarm (3) von dem Krangerüst (2) weg erfolgt, weist das hydraulische Zylinder-Kolbenaggregat (6) zum Verschwenken des Auslegerarmes (3) einen zusätzlichen Verschiebeantrieb (13) integriert auf, dessen Bewegungsrichtung im wesentlichen normal auf die Bewegungsrichtung des hydraulischen Zylinder-Kolbenaggregates (6) zum Verschwenken des Auslegerarmes (3) ist und durch welchen die Verschiebung der Anlenkstelle (10) des hydraulischen Zylinder-Kolbenaggregates (6) am Auslegerarm (3) von dem Krangerüst (2) weg beim Beginn der Schwenkbewegung des Auslegerarmes (3) erfolgt.

Figure 00000001
In a loading crane (1) with at least one boom arm (3) which can be pivoted about a substantially horizontal axis (4) on a crane frame (2), with the crane frame (2) which can be rotated about a substantially vertical axis (5) and the Cantilever arm (3) a hydraulic cylinder-piston unit (6) for pivoting the cantilever arm (3) is articulated and, at the beginning of the pivoting movement of the cantilever arm (3) from the completely swiveled-in position of the cantilever arm (3), a displacement of the articulation point (10) of the hydraulic Cylinder-piston unit (6) on the boom arm (3) away from the crane frame (2), the hydraulic cylinder-piston unit (6) for pivoting the boom arm (3) has an additional displacement drive (13) integrated, the direction of movement of which is essentially normal on the direction of movement of the hydraulic cylinder-piston unit (6) for pivoting the cantilever arm (3) and through which the displacement d he articulation point (10) of the hydraulic cylinder-piston unit (6) on the extension arm (3) away from the crane frame (2) at the start of the pivoting movement of the extension arm (3).
