VH 850 A

VH 850 AK  is a new generation of a combined roller with the high comfort for an operator, with up-to-date design and with splendid visibility from the operator's place. The machine is based on a rigid frame. The front axle consists of a vibratory smooth split drum with a machined surface, the rear axle is fitted with four rubber-tyred compaction wheels with a smooth tread. Both axles are driven and steerable. The VH 850 AK is designed for mid and large scale compaction jobs at asphalt, loose and semi-cohesive materials. It is equipped with a hydrostatic drive system, three mode steering system including the "crabbing mode", Cummins engine and hydraulic Sauer-Danfoss. It fulfils require-ments of pollutants emission directives 97/68/ECE Stage 1 and EPA/CARB Tier 1. The machine meets the CE marking conditions.
