A fixing device for chains (11) on a brush-clearing aggregate, containing in its plane a rotatable arranged head (1), centre (1), preferably in the form of a circular plate, at which the chains (11), normally three in number, are intended to be fixed and from which these are essentially designed to swing out in the named plane. Characterizing the fastening device is that the named centre (1) is comprised of three equal tracks (3) arranged in the named plane and equally divided with respect to the perimeter of the named centre (4), where each track (3) runs into two places (3, 6) on the periphery of the named curve (4) and run in an arc (7), preferably forming a part of a circle's arc (7), between these places (5, 6) and in each track (3) a securing ring (8) for a chain (11) is arranged and this part juts outside of the named periphery (4) of the centre (1) as well as where the track (3) at least is partly covered by a lid (9) or similar.<IMAGE> |
