ABSTRACT:
The invention relates to a vibrator roller for soil compaction, comprising an undercarriage having at least two roller drums disposed one after the other in the travel direction. Front and rear imbalance generators in the form of weights rotating with 180.degree. phase displacement are assigned to the roller drums, and the undercarriage carries the superstructure, via elastic resilient pads. These resilient pads are positioned at least in the vicinity of the minimum vibration of the undercarriage, so that practically total vibrational decoupling between the undercarriage and the superstructure is brought about.
