51.2" drum width
Articulated Tandem Roller

Pro roller series: 4.0-ton

The RD40 rollers offers well-balanced weight distribution on the front and rear drums ensuring very uniform compaction results as well as excellent driving stability and maneuverability. The tapered design provides an unobstructed view of the drum edges, machine environment and job site. The ergonomic operator’s platform with reduced vibration and articulated joint provide for maximum driving comfort. Drum offset allows for easy maneuvering when compacting along walls and provides a smooth finish.

Product availability can vary from country to country. It is possible that information / products may not be available in your country.


  • Three point articulated pendulum joint offers constant contact for better results, safety and a smoother ride
  • 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
  • Large drum diameter combined with low machine center of gravity ensure excellent compaction quality.
  • ROPS (Roll Over Protective Structure) can be folded back for transport



The drum offset allows for easy maneuvering when  compacting along walls. It reduces cut marks, increases productivity with less asphalt pushing and shoving.

Articulated Pendulum Joint


Uniform compaction, optimal driving stability: The three-point articulated pendulum joint ensures a uniform weight distribution on the front and rear drum at all times. This also improves the maneuverability and provides for maximum stability when turning curves.

Vibrating drum


Ideal for all traditional compaction work. 
The vibrating drum optimally oscillates the material to be compacted with quick successive vertical forces. The built-in eccentric weight provides for a fast rotation and an excellent compaction performance.

Oscillating drum


Flawlessly compacts even asphalt at low temperatures. Perfectly suited for the compaction of seams (hot to cold). Trouble-free operation on bridges. 
Rollers with an oscillating drum compact with a high efficiency, since the drums maintain permanent contact with the ground. With its two synchronous rotating eccentric weights, the drum uses forward and reverse movements to direct its entire compaction force into the ground.


Optimal view

Everything is perfectly within view: With the specially designed, tapered design of the roller, you always have an excellent view of the drum edges, the machine environment and the job site.
