The Unimat 09-475/​4S is a universal tamping machine for aligning the track position with millimeter precision. It works continuously as a leveling, lifting, straightening or tamping machine for tracks, switches and crossings. Continuous travel and cyclical tamping far into the switch area ensure extremely efficient work. The universal tamping machine is equipped with the digital recording device DRP (Data Recording Processing), which is used to record, evaluate and display various track parameters such as longitudinal height, direction, transverse height and torsion. Thanks to a newly installed tamping unit, it is significantly quieter, as the boxes only vibrate during immersion and loading.
