Abstract

Die vorliegende Erfindung betrifft einen Fahrzeugkran mit einem um eine liegende Achse wippbaren und um eine aufrechte Achse drehbaren Teleskopausleger (3) mit einem Anlenkschuss (4), aus dem Anlenkschuss austeleskopierbaren Teleskopschüssen (16-19) sowie mit zwei Abspannstützen (6), die gelenkig an einem der Schüsse gelagert sind, so dass sie aus einer zueinander im wesentlichen parallelen an den Schuss angeklappten Transportstellung in eine aufgerichtete Betriebsstellung schwenkbar, insbesondere V-förmig aufspreizbar, sind. Die Erfindung betrifft des weiteren ein Verfahren zur Montage bzw. Demontage der genannten Abspannstützen des Teleskopauslegers des Fahrzeugkrans. Erfindungsgemäß sind die Abspannstützen bei im wesentlichen horizontal liegendem Teleskopausleger abbaubar, werden auf neben dem Teleskopausleger vorgesehenen Konsolen abgelegt und nach Aufwippen des Teleskopauslegers von dem Teleskopausleger selbst von den Konsolen angehoben und verladen.The present invention relates to a vehicle crane with a lying around a lying Axis tiltable and about an upright axis rotatable telescopic boom (3) with a pivoting joint (4) telescopic telescopic shots (16-19) from the pivoting joint as well as with two guy supports (6), which are hinged to one of the shots are so that they are essentially parallel to the shot tilted transport position pivotable in an erect operating position, in particular V-shaped spreadable, are. The invention further relates to a Method for assembling or disassembling said guy supports of the telescopic boom of the vehicle crane. According to the invention the guy supports are included essentially horizontal lying telescopic boom degradable, are on next to stored the telescopic boom provided consoles and after teetering of the telescopic boom lifted by the telescopic boom itself from the consoles and loaded.
