Abstract
The invention relates to a method for load monitoring of a tamping unit of a track maintenance machine, wherein at least one sensor is arranged for recording a load on the tamping unit. In this, measuring data recorded by means of the sensor are stored over a time period (T) in an evaluation device, wherein at least one load-time progression for cyclical penetration operations of the tamping unit into a ballast bed is derived from the stored measuring data. With this, conclusions can be drawn as to the load stress situation of the tamping unit and the condition of the ballast bed.
