Abstract

Eine Befestigungseinrichtung zur verkippbaren Anbringung von Zusatzgeräten (50) an wenigstens einem Auslegerarm (22) eines Laders (10), bei der wahlweise Mittel für eine permanente Befestigung durch Montage oder Mittel für eine Schnellkupplung gegeneinander austauschbar sind, weist eine durch einen Drehzapfen (32) gebildete Kippachse zwi­ schen Auslegerarm (22) und Zusatzgerät (50) auf, deren re­ lative Lage, unabhängig von der Wahl zwischen einer per­ manenten Befestigung oder einer Schnellkupplung, in etwa beibehalten wird. Unabhängig von der Art der Befestigung behalten damit bestimmte Punkte des Zusatzgerätes (50) ihre relative Lage zum Auslegerarm (22) bei, so daß die wirksamen Abmessungen und kennzeichnenden Konstruktions­ merkmale von Lader (10) und Zusatzgerät (50) unverändert bleiben. A fastening device for tiltable attachment of additional devices (50) on at least one cantilever arm (22) of a loader (10), in the case of which optionally means for a permanent attachment by assembly or means for one Quick coupling are interchangeable, points a tilt axis formed by a pivot (32) cantilever arm (22) and additional device (50), the right relative location, regardless of the choice between a per manent attachment or a quick coupling, approximately is maintained. Regardless of the type of attachment keep certain points of the additional device (50) their relative position to the extension arm (22) so that the effective dimensions and distinctive construction Features of loader (10) and additional device (50) unchanged stay.
