Doosan Construction Equipment has launched the DX210W-5, a 21-tonne Stage IV-compliant wheeled excavator. As well as meeting the latest Stage IV emission regulations, the DX210W-5 goes much further and sets a new benchmark for wheeled excavator design worldwide. This achievement is marked by a distinctive new machine styling scheme that is common to all new Stage IV machines from Doosan. The new DX210W-5 offers enhanced comfort and controllability together with new features to boost fuel efficiency, uptime and return on investment, with a focus on increased power, robustness and agility.
In common with all Doosan Stage IV excavators above 14 tonnes, the DX210W-5 is factory-installed with the new CoreTMS state-of-the-art wireless fleet monitoring system. Designed specifically for the Doosan range, the CoreTMS system is a new tool providing comprehensive information about machine performance in a dual mode (satellite, GSM). Because the software in the CoreTMS system has been upgraded to communicate directly with the EPOS system on a Doosan excavator, it is the only tool of its type capable of providing this level of information, delivering insightful and cost-saving data about equipment to help customers work more effectively.
The new DX210W-5 excavator is powered by the well-proven 6-cylinder, turbocharged Doosan DL06P water-cooled diesel engine, which is one of the most reliable and fuel efficient ever produced by Doosan, providing an output of 141.2kW (189hp) at 1,900rpm, a massive 17% increase in engine power over the previous-generation machine. The DL06P engine offers convenience and lower costs by meeting Stage IV emission regulations without the need for a DPF, through the use of cooled EGR and SCR aftertreatment technologies.
As well as the DL06P engine, new innovative and exclusive features have been introduced that reduce fuel consumption by an average of 10%. Among these features is the new Trip Meter Setting screen which allows operators to check fuel consumption daily (or over a desired period) directly from the control panel; and to save even more fuel, there is a special Doosan-developed system, Smart Power Control (SPC), which monitors both engine and pump power and limits unnecessary outputs depending on whether the work is light or heavy. The SPC can be used with all four work modes (E, S, P, P+).
Further fuel efficiency results from the electric fan clutch on the DX210W-5 excavator, which drives the cooling fan at optimum speed. Based on coolant, hydraulic oil, cooled charged air temperatures and target engine speeds, the fan speed is controlled electrically resulting in much lower fan noise and better fuel efficiency.
As well as the 17% increase in engine power, the DX210W-5 has 14% more engine torque. The new Posicon hydraulic system also offers a 3% increase in hydraulic capacity, which translates into an 8% improvement in the bucket force and 6% more arm force. The 900kg weight increase and the greater machine width result in front-lifting capacities being increased by 4 8% (attachment down/up), while the over-the-side capacities have increased by 12 15% (attachment down/up).
