<p>Apparatus for removing weld surplus formed after the aluminothermic welding of two rail butt ends, and incorporating a frame, a first cutting tool secured to the frame and a second cutting tool movable relative to the frame towards the first tool to remove the weld surplus. This apparatus is characterized by the fact that both tools have a cutting edge each with a profile suitable for cutting only the weld surplus on top of the rail head, and the second tool may either be moved horizontally and parallel or perpendicularly to the longitudinal axis of the rail by a hydraulic jack whose body is attached to the frame and whose ram is fixed to the second tool above its cutting edge.</p> |
