System for distributing ballast in a track bed

摘要

A machine for distributing ballast in a track bed comprises a machine frame supported on the track by undercarriages for mobility in an operating direction, a ballast plow adjustably mounted on the machine frame for distributing the ballast in the track bed, drives for adjusting the ballast plow relative to the machine frame, a contactless sensor arranged ahead of the ballast plow in the operating direction for detecting an existing track bed profile extending perpendicularly to the longitudinal direction, a position indicator for indicating a change in the position of the ballast plow relative to the machine frame, and a control for the drives comprising a memory storing a desired track bed profile.
