Abstract

Die Erfindung betrifft einen Kran mit einem Teleskopausieger, dessen austeleskopierbare Schüsse nach dem Lösen von arretierenden Bolzenverbindungen durch Kupplung mit einer Verschiebeeinrichtung aus- und einfahrbar und in der jeweils aus- oder eingefahrenen Stellung verriegelbar sind, wobei eine Kupplungs- und Verriegelungseinheit, die mit den austeleskopierbaren Schüssen über ein Kupplungselement kuppelbar ist, am verschiebbaren Element der Verschiebeeinrichtung vorgesehen ist und an jedem austeleskopierbaren Schuß an seinem hinteren Ende auf der Innenseite mindestens ein Verriegelungselement angeordnet ist, das mit der Kupplungs- und Verriegelungseinheit verbindbar und das in eine Aufnahme des den teleskopierbaren Schuß umfassenden Schusses ein- und ausschiebbar ist. Dabei ist am verschiebbaren Element (8) der die Teleskopschüsse (1,2) ein- und austeleskopierenden Verschiebeeinrichtung mindestens ein senkrecht zur Achse der Verschiebeeinrichtung liegendes Kupplungselement (7,7. 1) mit einem in radialer Richtung bewegbaren Kupplungsteil (15, 15.1) vorgesehen, das mit einem achsgleich bewegbaren Verriegelungsbolzen (24, 24.1) eines Verriegelungselementes (6,6.1) formschlüssig kuppelbar ist, wobei in Entriegelungsstellung der Verriegelungsbolzen (24, 24. 1) in Kombination mit dem Kupplungsteil (1 5, 15. 1) die Kupplung zwischen der Verschiebeeinrichtung (8) und dem jeweiligen ein- und auszuteleskopierenden Teleskopschuss (2) darstellt, wobei in der Übergangsphase zwischen Entriegelung und Verriegelung jeweils ein vorstehender Bereich des Kupplungsteiles (1 5,15. 1) und des Verriegelungsbolzens (24,24. 1) formschlüssig zur Anlage kommen.
