VH 270
 | VH 250 and VH 270 are small tandem vibratory rollers with an articulated frame and two smooth drums with a finished surface. Both drums are driven and vibrating.VH 250 K is a combined vibratory roller with an articulated frame. The front axle consists of a smooth vibratory drum with a machined surface, the rear axle is fitted with four rubber-tyred compaction wheels with a smooth tread. Both axles are driven. Vibration sources are one stage non-rectified vibration exciters placed in the drum axis. The drive of all machine functions is hydrostatical. The machine is equipped with Deutz engine, hydraulic Hydromatic-Rexroth. It fulfils the requirements of pollutants emission directives 97/68/ECE Stage 2 and EPA/CARB Tier 1. It meets the CE marking conditions. |
