DX190W Wheel Excavator


March 7, 2013 - Equipment

The DX190W-3 is powered by a 176-hp, 6-cylinder DL06KB water-cooled diesel engine that has been optimized for use with a cooled exhaust gas recirculation (CEGR) system, diesel oxidation catalyst (DOC), and diesel particulate filter (DPF). The engines in this configuration are optimized to reduce nitrogen oxide (NOX) and after-treatment is needed to reduce particulate matter, to comply with iT4 emission regulations. The turbocharged engine features a high-pressure common-rail design with direct fuel injection, electronic control and four valves per cylinder.

The Electronic Power Optimizing System (EPOS) features four work modes — digging, breaker, shear, and the new lifting mode —  and auto-idle. Operators can work more effectively with multiple operating modes, easy-to-read display monitors and precise control levers. The new Power + mode provides improved performance and faster workgroup speeds for heavy-duty work.

A new electronic fan clutch reduces fuel consumption and noise levels, while providing cooling system improvements. Outriggers can be controlled individually to level the machine on uneven surfaces.  The front axle oscillates for better steering angles, but can be locked for better digging and lifting performance.
