Abstract

A compaction device includes at least one traveling drum rotatable about a drum shaft and having vibration exciters including unbalanced masses rotating out of phase by 180 degrees in the same direction of rotation and generating an oscillation torque about the drum shaft, and having a drive shaft running coaxial to the drum shaft for driving the vibration exciters. The drum is divided at least once and each drum part includes at least two coupled vibration exciters mounted at a distance from the drum shaft in the drum.
