Product Information Sheet

All of the technical information on this product at a glance on the Product Information Sheet.

Description

Due to the specially tapered design of the articulated tandem-axle rollers, the operator always has the drum edges, the machine environment and the job site in view. 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. In crab steering mode, you can also easily compact in narrow edge areas or along curbs.

  • Optimal visual conditions due to the slim design
  • Edge pressing and cutting equipment for a clean edge of the paths
  • Safe ROPS (Roll Over Protective Structure) that can be folded back for transport
  • Installed articulated pendulum joint ensures for uniform compaction, a high level of maneuverability and a high level of driving stability
  • Three model versions: Tandem-axle roller with 2 vibrating drums, combination roller or tandem-axle roller with oscillating drum
