Rail grinding machine for grinding rails of a track

Abstract

A rail grinding machine for grinding rails of a track has a machine frame, on which guide rollers for manual movement of the rail grinding machine in a longitudinal direction are mounted. By use of a cross slide, which is mounted on the machine frame, a grinding unit can be moved in a transverse direction. The cross slide contains a closed cross slide frame, which extends in the longitudinal direction and the transverse direction. The closed cross slide frame enables a simple and stable construction of the rail grinding machine and flexible adjustability of the grinding unit.
