A new EU Stage IIIB compliant 19 tonne class DX190W-3 wheeled excavator has been launched by Doosan Construction Equipment. Powered by a 129.4kW engine, the DX190W-3 boasts a 9% increase in engine power compared to the Stage IIIA model, while torque is up 4%, according Doosan. The new machine has also demonstrated a 12% reduction in fuel consumption in factory testing. A new ECO Gauge on the control panel monitors in real time the rate of fuel consumption and actual engine-percent load to help guide the operator to select the best operating mode for fuel economy.
