METHOD AND MACHINE FOR LOWERING A TRACK

摘要

For the controlled lowering of a track (2), in a rear scanning location (11) of a measuring system (10) a longitudinal slope (a) of the track (2) is captured and recorded. For a length extending back at least (10) meters, a current height profile (16) is generated and a rear compensation line (17) overlaid thereon and representing a target track position is calculated. The rear scanning location (11) is computationally guided along the rear compensation line (17) such that a compensation value for the position of the measurement axis (12) results at a center scanning location (11) positioned between the rear and a front scanning location (11).
