The heavyweight class. BOMAG's heavy duty BW 211 D-5 compactor can withstand any challenge. All construction projects have one thing in common: they require load-bearing subsoil. Which is why single drum rollers play a crucial part in the construction process. Specifications, however, are highly diverse. A contractor working next to a listed house has to use an entirely different compaction method to that used in conventional road construction. This model is used on larger projects – for compaction work on a major site or for road construction, inside or outside towns.
