The 16-tonne DX160W-3 and 14-tonne DX140W-3 wheeled excavators offer several new features and product improvements beyond meeting the stricter emissions requirements.
The DX140W-3 was first seen at the Intermat exhibition.
Main pump flow of the new models has increased by 8% and system pressure has risen to 350-370 kg/cm2.
Bucket forces have been increased by 16% and arm forces by between 6% and 16%.
Lifting capacities have been increased by between 3% and 12% over the front of the excavators.
Power is increased by 2%, with 12% more torque and a 10% increase in traction force, Doosan says.
In additional, fuel consumption is reduced by up to 9%, the manufacturer says.
