The Vortok Stressing Roller (VSR) is designed to attach to the rail fastening and, by means of a rotating lift arm and bearing, contacts the underside of the rail head to lift the unclipped rail from the sleeper (tie).
Once lifted, the rail can be moved with very low friction for the purposes of rail stressing. The resultant stress distribution is, therefore, optimised. The VSR can also be used for changing rail pads.
