The collapsible fixture can be fitted on the arm (2) of a normal excavator for drilling holes for posts, and when not in use can be folded up to allow the excavator to be used normally. The fixture comprises a hydraulically foldable arm (3) in the end of which a drilling fixture (7,8) is fitted in an articulated manner, and which can be folded in towards (and locked against) the arm by turning the drill (8). |
