Mobile tamping, leveling and lining machine

摘要

A mobile track tamping, leveling and lining machine comprises a vertically and laterally movable lifting and lining tool carrier for correcting the track position. Two track rail engaging rollers or each track rail are mounted on the carrier and the rollers are arranged on opposite sides of each rail and have a circumferential configuration conforming to the side faces and undersides of the head of the rail on opposite sides thereof. A pivoting arm is connected to each roller and is pivotal on the tool carrier about a vertical axis for pivoting the rollers in a plane substantially parallel to the track. Drives are connected to each pivoting arm for driving the rollers into force-transmitting engagement with the conforming side face and underside of a respective track rail.
