Additional blade for ploughs on road maintenance machinery, with which blade it is possible, where necessary, to prevent a wall of snow or ice forming at individual road junctions 5 and at road crossings during ploughing, without changing the ploughing angle of the actual plough blade 1. The additional blade 3 describes simultaneously, between the rest position and the work position, both a rotating movement and a vertical movement. In the work position, the additional blade removes the accumulated snow from the road junction. <IMAGE> |
