<p>The invention relates to a screw device for high-adjusting and aligning rails on a track infrastructure comprising a transversal cantilever beam which clamps the rail on the underside and is fixed to a long nut (4) which is variably high guided along a high- adjusting screw (3). The inventive screw device is characterised in that the transversal cantilever beam is embodied in the form of a horizontal screw plate (7) which is pivotally arranged around a horizontal axis (20) on the long nut and on which a truck provided with a clamp fixing device (10,11) for a rail base can perpendicularly move with respect to the high-adjusting screw with the aid of a second screw device (14, 16, 17).</p> |
