Doosan DX490LC-5

Dig with power and confidence, work in comfort, and stay on the job longer with the Doosan® DX490LC-5. It’s a steady performer in the 40-50 metric ton size class.

Strength starts with an unbeatable engine and hydraulic system. The high pressure common rail fuel injected engine and electronic power optimizing system (EPOS) deliver the most power and fuel efficiency.

The hydraulic system output requirements are optimized with engine horsepower. The resulting efficiency increases productivity and reduces fuel consumption. Improved feedback through the controls results in smoother machine control and enhanced operator comfort. For further fuel savings, auto shutdown helps owners save fuel during non-working conditions.

Enjoy reduced maintenance costs and extended machine life with the durable x-chassis, strengthened boom and arm assemblies, the extended greasing intervals. Easily access the battery, oil filter, air cleaner, fuel filter, radiators and other engine components.

The arm grease points are grouped for easy maintenance. A variable speed hydraulic fan regulates airflow through the oil cooler. Monitor your Doosan heavy equipment and manage maintenance to reduce operating costs with Doosan Connect Telematics.

A spacious cab offers excellent visibility, adjustable controls and high-performance air conditioning. The reclining, height and weight-adjustable standard air suspension seat has a headrest and adjustable armrest. A rear view camera, and optional side view camera provide even better visibility. A split screen function allows up to three camera displays to be viewed at once. 

To reach Tier 4 emissions standards, the DX490LC-5 incorporates a high-pressure common-rail (HPCR) fuel delivery system as well as cooled exhaust gas recirculation (CEGR) combined with a diesel oxidation catalyst (DOC) and selective catalyst reduction (SCR).
