Abstract
A railway maintenance device movable on a railroad track having a pair of spaced rails, the device including a frame configured for movement relative to the track and having at least two side members. At least one track contacting element is associated with at least one of the sides. An adjustment mechanism is provided for adjusting the relative position of at least one of the track contacting elements to the frame to thus position the frame relative to the rails. The device preferably includes a fluid power cylinder associated with each track contacting element to control the position of the wheel relative to the frame, as well as a stop mechanism for adjustably limiting the pivoting action of the contacting element relative to the frame, and thus control the displacement of the element.
