The Doosan DX140W wheel excavator combines increased power and performance with interim Tier 4 updates, and new technologies make this excavator a good solution for highway and street development, commercial construction, bridge and railway development and dealer rental.

The DX140W is powered by a 135-hp, 6-cylinder DL06KB water-cooled diesel engine that has been optimized for use with cooled exhaust gas recirculation system, diesel oxidation catalyst and diesel particulate filter. The turbocharged 359-cubic-inch engine features a high-pressure common-rail design with direct fuel injection, electronic control and four valves per cylinder.

The Electronic Power Optimizing System is designed to provide optimum power and fuel efficiency via four work modes, auto-idle and machine diagnostics. Operators can work more effectively with multiple operating modes, easy-to-read display monitors and precise control levers. The new Power Plus mode provides improved performance and faster workgroup speeds for heavy duty work. Four work modes — digging, breaker, shear and the new lifting mode — allow operators to get maximum efficiency and fuel economy in specific applications.

“A new feature on the Doosan DX140W is that the forward/neutral/reverse has been moved from a lever on the right steering column to a switch on the front right hand joystick,” says Mike Stark, Doosan heavy excavator product specialist. “This allows the operator to change directions without removing his hands from the joystick or steering wheel. The four power modes and four work modes of the new Doosan DX140W allow the operator to adjust the performance of the excavator to their specific task.”
