ABSTRACT:
A plough to be applied to a machine for rehabilitating a railway track, for performing the operation consisting in displacing the ballast to be renewed. Lateral ejectors are applied to the lower portion of the plough and actuated alternatively for breaking the compact ballast and push the gravel so as to gradually accumulate same on the sides and afford and easy forward travel of the plough for making a relatively deep cutting into which the new ties can be laid without requiring a subsequent sinking thereof. The lateral ejectors are actuated two at a time, one to the right and the other to the left, for compensating side stress. A possible mechanism for actuating the lateral ejectors comprises rockers having unequal arms and actuated by a hydraulic cylinder.
