Connecting device for coupling tool to crane arm

摘要

The connecting device comprises two plate-shaped members (5,6), one member (5) for fixing on the crane arm (2) and the other member (6) for fixing on the tool (4). Sleeves are fastened on the opposite lying sides of the plate-shaped members and form a mutual extension if the elements are interconnected. The members can be interconnected by means of connecting pins running through the sleeves. One plate-shaped member (6) is provided on one side with two sleeves spaced apart and between which fits a sleeve connected to the other plate-shaped member (5).
