Greater fuel efficiency, improved digging performance and revised styling are among the changes to be found on Volvo’s latest D-series wheeled excavators. The four-model EW range spans 14-21tonnes and benefits from a new engine, cab, hydraulics, substructure, boom, arm and controls. There is more power with D-series, from stage IIIB engines that use V-ACT technology. The four cylinder (EW140D) and six cylinder engines produce high torque at low engine speeds, said Volvo, giving rise to low fuel consumption.
