The Doosan DX140LC-3 and DX180LC-3 excavators are interim Tier 4 (iT4) compliant machines that have been upgraded to allow operators to customize the excavator to a variety of working conditions.

Powered by 6-cylinder DL06K engines, the DX140LC-3 and DX180LC-3 engines feature 109 and 125 hp, respectively. Both excavators use a water-cooled diesel engine that has been optimized for use with cooled exhaust gas recirculation (CEGR) system, a diesel oxidation catalyst (DOC), and a diesel particulate filter (DPF). Engines with this configuration are optimized to reduce nitrogen oxides, and after-treatment is needed to reduce particulate matter, to comply with iT4 emission regulations. The turbocharged engines feature a high-pressure common-rail design with direct fuel injection, electronic control, and four valves per cylinder.

A new electronic fan clutch reduces fuel consumption and noise levels, while providing cooling system improvements. The Electronic Power Optimizing System (EPOS) provides 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 + mode provides improved performance and faster workgroup speeds for heavy-duty work. The machines feature four work modes — digging, breaker, shear, and the new lifting mode. The maximum speeds are 3.1 mph for the DX140LC-3 and 3.2 mph for the DX180LC-3.

For operator comfort, the machine provides enhancements to the Roll-Over Protective Structure (ROPS) cabin. Both a height lever and tilting function were added to the air suspension heated seat. The cabin mounting mechanism has been improved with a thickened dampening plate, and an internal coil spring has been added to reduce cabin vibration 20%.

The Doosan DX140LC-3 and DX180LC-3 — like every new Doosan machine — are covered by an 48-hour parts guarantee. The program guarantees that if a “machine-debilitating” part is needed, Doosan will deliver it directly to the end user within two business days or Doosan will pay for a replacement machine rental. The 48-Hour Parts Guarantee is subject to carrier delivery restrictions and/or governmental agency delays.
