Abstract

L'invention concerne un système de grue automotrice (1), comprenant une grue automotrice (2) qui comprend une pièce de montage (7), en particulier un dispositif d'ancrage, pouvant être montée sur la flèche télescopique ou démontée de celle-ci, ainsi qu'une unité de transport de pièce de montage (5) conçue pour le transport de la pièce de montage (7), pour une pièce de montage (7) d'une flèche télescopique (3) d'une grue automotrice (2). Pour pouvoir effectuer le transport et le déplacement de la pièce de montage (7) de manière plus rentable et plus réalisable, le dispositif de transport (6) mobile conçu selon l'invention pour le transport de la pièce de montage (7) est muni d'au moins un bras de chargement (13), dont l'extremite de support (15) libre peut être couplée à une pièce de montage (7) étant ou devant être reçue sur le dispositif de transport (6). Le bras de chargement (13) est disposé de manière mobile sur le dispositif de transport (6) de telle façon que la pièce de montage (7) peut être déplacée entre le dispositif de transport (6) et la flèche télescopique (3). Le dispositif de transport (6) possède en outre un dispositif inclinable (9), lequel est conçu pour le levage et l'abaissement unilatéral de la pièce de montage (7) étant ou devant être reçue sur le dispositif de transport (6).
