Date Jun. 1, 1989.Snow-ploughs for frontal mounting on road vehicles are provided with an avoidance device, which in known types can be implemented by means of two circular curved guides. This poses problems, however, during mounting as well as during avoidance, particularly on hard surfaces. In order to ensure firm and reliable mounting of the plough blade (1) on the curved guide and hence problem-free avoidance, the curved guide is designed as a sliding bearing. To this end, it comprises a first and a second curved actions. A forced limiter with a descending characteristic curve is also provided. The snow-plough is suitable for use as road snow-plough. |
