Abstract

Die Erfindung betrifft eine Klappspitzen-Abwinklungsvorrichtung für einen Mobilkran (20), mit einem Gelenkbereich (9), durch dessen Abwinklung der Winkel der Klappspitze (10) eingestellt wird und der ein Gelenk (8) im oberen bzw. im Zuglast-Bereich aufweist, bei welcher der Gelenkbereich (9) im unteren bzw. im Drucklast-Bereich eine mechanisch feststellbare Teleskopiereinrichtung (7) aufweist.

Figure 00000001
The invention relates to a folding tip bending device for a mobile crane (20), having a hinge region (9), by the angling of which the angle of the folding tip (10) is adjusted and which has a joint (8) in the upper or in the tensile load region, in which the hinge region (9) has a mechanically detectable telescopic device (7) in the lower or in the pressure load region.
