The Doosan stand at the CONEXPO-CON/AGG exhibition will provide the launch-pad for the company’s latest excavators and wheel loaders. The line-up of new Final Tier 4/Stage IV compliant machines on the Doosan Booth No 1501 will be revealed on the first day of the show, but the Doosan booth will also feature a number of recently launched interim Tier 4/Stage IIIB compliant excavators and wheel loaders being shown for the first time at CONEXPO-CON/AGG, including the new DX140LCR-3 crawler excavator, the DX190W-3 wheeled excavator and the DL200-3 wheel loader.
The DX140LCR-3 reduced swing excavator is powered by the Cummins QSB 4.5 common rail 4-cylinder turbocharged diesel engine featuring the latest evolution in maintenance-free Diesel Oxidation Catalyst (DOC) after-treatment technology to meet Stage IIIB engine emission regulations. The engine runs at 2200 RPM and delivers 11 percent more power (81 kW) and 10 percent more torque (49.8 kgf.m) compared to the previous Stage IIIA compliant DX140LCR model.
Arm and bucket forces have been increased by up to eight percent along with the travel speed which can now reach 3.2 and 5.3 km/hour in the low and high range, respectively. Owing to the incorporation of a 400 kg heavier counterweight (3,500 kg), the lifting capacities for the new DX140LCR-3 excavator have also been boosted by up to seven percent.
With operating weights varying from 18.4 to 20.3 tonnes, the new Doosan DX190W-3 wheeled excavator is a true 18-19 tonne class machine. Powered by the well-proven Stage IIIB compliant Doosan DL06KB 6-cylinder ‘common rail’ diesel engine, fitted with a waste gate turbocharger with intercooler as standard and developing 129.4 kW at 1900 RPM, the DX190W-3 model offers more power than other machines in this class. This is combined with a huge hydraulic capacity to produce the highest arm and bucket forces together with the highest traction force on the market.
Like all Doosan new generation machines, the DL200-3 wheel loader features a new cab design offering better visibility thanks to a wider front glass section and an extended wiper blade area. Now that the reservoir for the wiper water is located on the outside of the cab, space inside has been increased, providing more foot room. The air conditioning system is regulated automatically by a temperature sensor.
A new instrument panel has an integrated VCU (vehicle control unit). The control panel has been redesigned for more convenience, allowing the operator to choose the information they wish to have displayed. Using the Main Menu, the operator has access to several functions and machine information. Data such as pressure, temperature and engine speed can be monitored in real time. The operator and service staff are able to get detailed information via the Special Menu.
Powered by the Doosan DL06K ‘common rail’ 6-cylinder turbocharged diesel engine delivering 119 kW at 2,100 RPM, the DL200-3 wheel loader combines high engine power with a number of new features to minimise fuel consumption and provide better operator comfort, exceptional performance, ease of handling, easier serviceability and extended durability.
