Doosan's 14-metric-ton DX140R excavator with reduced swing radius produces the same bucket and arm breakout forces as the conventional DX140LC, but tractive effort and tracking speed is increased aboutrn6 percent and maximum pump flow has been pushed to 60 gpm. The counterweight extends justrn7 inches beyond the track width. The six-cylinderrnDoosan diesel in the DX140LC was swapped with a Cummins four cylinder to fit the DX140R's smaller compartment, but power remains the same with 96 horsepower at 1,850 rpm. Maximum dig depth is just over 18 feet.
