ABSTRACT:
A mobile rail grinding machine comprises a machine frame extending in a longitudinal direction, and undercarriages supporting the machine frame on the track rails for movement in an operating direction. A mounting frame is supported on the track rails by flanged wheels, and a drive vertically adjustably connects the mounting frame to the machine frame. At least one rail head grinding unit is arranged on the mounting frame and comprises an abrasive belt having opposite ends, a storage spool holding one of the belt ends and a collecting spool holding the opposite belt end whereby the abrasive belt may be reeled off the storage spool and onto the collecting spool, and a pressure element arranged to press the abrasive belt against the surface area of the rail head off which the irregularities are to be ground. The grinding unit is positioned adjustably horizontally and in the longitudinal direction, and a driving mechanism imparts an oscillating motion to the grinding unit, which motion is superimposed on the movement of the machine frame in the operating direction.
