Exceptional Power and Control
The high-pressure common rail fuel injected engine and electronic power optimizing system (EPOS) provide optimum power and fuel efficiency. Four work modes, auto-idle and machine diagnostics help you manage your fuel costs. For even greater fuel efficiency, auto shutdown helps owners save fuel while the machine isn't working.

Designed for long life with a robust frame and reinforced superstructure, the Doosan® DX255LC-5 is built for reliability. Boom and arm bushings and ultra-hard wear disks deliver dependable performance and extended service intervals. The permanently sealed and lubricated track links maximize uptime and reduce operating costs.

Comfort and Convenience
A spacious cab means better visibility and more productivity. High-performance air conditioning, extra storage and the reclining, height- and weight-adjustable standard air suspension seat with a headrest and adjustable armrest give you better comfort.

Reduced, Simplified Maintenance
Enjoy reduced maintenance costs and extended machine life with the durable x-chassis, strengthened boom and arm assembly, and extended greasing intervals. Easily access the oil filter, air cleaner, fuel filter, radiators and other engine components. The centralized boom and arm grease points are grouped for easy maintenance. Monitor your Doosan heavy equipment and manage maintenance to reduce operating costs with Doosan Connect Telematics.

Tier 4 Technology
To comply with Tier 4 emissions standards, the DX255LC-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).
