Abstract

Die Erfindung betrifft einen fahrbaren Kran (1) mit einem Teleskopausleger (12), bestehend aus einem Grundkasten (13) und mehreren mittels einer Teleskopiereinrichtung aus- und einfahrbaren Teleskopschüssen (14-18), wobei mindestens ein Teleskopschuß in Richtung des neigbaren Auslegers (12) durch eine schließ- und öffnenbare mit einem Scharnier (26) und einem Verstellmechanismus versehene Abknickstelle (19) verschwenkbar ist. Dabei ist mindestens der innerste Schuß (18) verschwenkbar und rückwärtig daran schließt sich wenigstens ein nicht abgeknickter Teleskopschuß (14) an.
