Stressing Roller
The Pandrol Vortok Stressing Roller attaches to the rail fastening and, using a rotating lift arm and bearing, contacts the underside of the rail head to lift the unclipped rail from the sleeper.
Throughout this process, the rail is kept centralised between the fastening shoulders for safety and accuracy as the lift action self-locks the VSR in the raised position. Once lifted, the rail can be moved with very low friction, optimising stress distribution for maximum results.
