Wacker Neuson RD28-120 O

RD28-120 O

Perfect view – perfect performance

Due to the specially tapered design of the articulated tandem-axle rollers, the operator maintains an excellent view of the drum edges, the machine environment and the job site. This ensures ideal compaction results. The ergonomic operator's platform, the vibration-reduced driver's cabin and the 3-point articulated joint provide for maximum driving comfort. Drum offset allows for easy maneuvering when compacting along walls and provides a smoother finish.

  • Three model version available: Tandem-axle roller with two vibrating drums; combination roller with vibrating front drum with pneumatic rear tires; vibrating front drum with oscillating rear drum
  • Vibration and oscillation can be adjusted in two levels
  • ROPS (Roll Over Protective Structure) can be folded back for transport
  • Three point articulated pendulum joint offers constant contact for better results, safety and a smoother ride
  • Large drum diameter combined with low machine center of gravity ensure excellent compaction quality.
