Patent ID: 8186070

Claim:
A method for the controlled lowering of a track, which comprises the following method steps: setting the track in transverse vibrations with the aid of dynamic striking forces and loading the track with a vertical static load, and controlling a settlement defining the lowering of the track with a measuring system for tracing a track position, the measuring system having a measuring chord extending in a longitudinal direction of the machine and having tracing points configured to roll on the track and including a rear tracing point and a front tracing point, with reference to a working direction; detecting and storing a longitudinal inclination of the track at the rear tracing point in connection with a distance measurement; from the stored values for the longitudinal inclination and the distance measurement, forming a current vertical profile of the track for a length of track reaching back at least 10 meters from the rear tracing point with regard to the working direction, and calculating a rear compensation straight line that is superimposed upon the vertical profile and renders a target track position; guiding the rear tracing point by calculation along the rear compensation straight line so that a compensation value for the position of the measuring chord ensues at a middle tracing point positioned between the rear tracing point and the front tracing point.
