TRACK MAINTENANCE MACHINE FOR COMPACTING BALLAST

摘要

TRACK MAINTENANCE MACHINE FOR COMPACTING BALLAST A continuously advancing track maintenance machine for compacting ballast comprises a self-propelled machine frame supported on the track for continuous advancement, a powerdriven and vertically adjustable track stabilization assembly mounted on the machine frame and comprising rail engaging roller tools, drive means for spreading the roller tools into engagement with the gage sides of the rails, and vibrating means for imparting oscillations to the roller tools in a direction extending substantially in a horizontal plane transversely to the longitudinal machine frame extension whereby the roller tools engaging the rails transmit the oscillations to the track, a device for measuring the amplitudes of the horizontal oscillations, and a reference system for monitoring the track level between an actual level of the track and a desired level thereof.
