Abstract A device for the levelling and profiling of railroad ballast beds has two lateral ploughs, one designed to operate outside each rail. Each lateral plough is identical and comprises a blade connected through a joining member to a main support arm which is movable in a plane substantially perpendicular to the longitudinal axis of the track. The support arm is connected to the chassis of the device by means of a hydraulic jack acting at one point on the arm and a double link connected to a second spaced point on the arm. The hydraulic jack is operable to adjust the height of the blade and a further hydraulic jack is connected to the double link to adjust the lateral position of the blade. The arm is preferably of rectangular cross-section and arranged between two lateral supporting walls of the chassis. The joining member is capable of pivoting action about two mutually perpendicular axes and two further hydraulic jacks are arranged to change the angular position of the joining member in relation to the support arm and the angular position of the blade in relation to the joining member.
A mobile device moveable on a track having at least one rail for the levelling and transverse profiling of railroad ballast beds, the device comprising a chassis, at least one lateral plough associated with one rail for operating outside the rail, in which the lateral plough comprises a blade, an arm movable in a plane substantially perpendicular to the longitudinal axis of the track and connected to the chassis by at least two connecting links parallel with said plane and pivotally connected at their one ends to two points spaced along the arm and pivotally connected at their other ends to two spaced points on the chassis, one of the two connecting links being in the form of an extensible element adjustable in length and the other of the two connecting links being connected to an element for adjusting the angular position of the other link in relation to the chassis whereby through movement of the two links the height and lateral position of the blade is controllable, the blade being pivotally connected at a third point on the arm by means of a joining member having two pivot axes ar right angles to each other, the joining member being connected to an element for adjusting the angular position of the joining member in relation to the arm, and being connected to an element for adjusting the angular position of the blade of the plough in relation to the joining member.
