Snow plough with swivelling frontal plough blade - ensures equal side projections for blade swung to right or left

摘要

The snow plough has a clearing blade able to rotate about the vertical axis of a supporting vehicle. The vehicle frame has two pivoting arms of equal length which are in contact with pivot bearings on a yoke behind the blade. A clamping arrangement holds the blade in the rotated positions. The rotation of the arm and of the blade ensures skew or straight positions and the side projections remain equal on both sides. - The support yoke is held parallel to the vehicle transverse axis. The separating distance between the front pivot axis (4) is smaller than the distance between the rear pivoting axis (6) on the vehicle. The swivelling arms (5) can be adjusted vertically on the rear pivot axis (6).
