Construction vehicle, in particular an excavator, with shiftable leader

摘要

To rapidly adjust a leader, it is proposed that the slewing boom 1 rotatably fastened to the construction vehicle by means of a slewing arm 2 be connected below this fastening point to a shifting cylinder 3, the other end of which is likewise connected to the slewing arm 2. Furthermore, a plate 7 bears against the end face 6 of the slewing boom 1. The plate 7 is rotatably fastened in its centre and can be moved parallel to the end face 6 via adjusting cylinders 9. The leader 11 is rotatably fastened to the plate 7 or the slewing boom 1 via pivot pins 14 and is actuated via a slewing motor 15. <IMAGE>
