Higher productivity. More efficiency.
In the 28-33 metric ton size class, few machines match the Doosan® DX300LC-5. It has the horsepower to tackle larger projects, but is designed to keep fuel and maintenance costs low.

Its high-pressure common rail fuel injected engine teams with the electronic power optimizing system (EPOS) provide optimum power and fuel efficiency. Choose between four work modes, auto-idle and machine diagnostics. For further fuel savings, auto shutdown helps owners save fuel during non-working conditions.

Comfort and Convenience
Work naturally inside the cab with controls that are placed where you need them. Easily control machine functions with comfortable joysticks. Change between ISO to BHL control patterns. Select the correct auxiliary flow rate using a switch on the control pattern.

A spacious cab provides visibility in all directions, while a standard rear camera gives you an even better view to your work. Choose the optional side camera for the most visibility.

Enter and exit easily through the large door opening. The high-performance air conditioning offers adjustable airflow and five operating modes. The adjustable reclining air suspension seat offers lumbar support. An emergency engine stop is located at the base of the seat.

Reduced, Simplified Maintenance
Designed for long life with a robust frame and reinforced superstructure, the DX300LC-5 is built for reliability. Boom and arm bushings and ultra-hard wear disks are designed for extended service intervals and steady performance. The permanently sealed and lubricated track links maximize uptime and reduce operating costs. Maintenance is simple with fast access to the battery, oil filter, air cleaner, fuel filter, radiators, and other components. Monitor your Doosan heavy equipment and manage maintenance to reduce operating costs with Doosan Connect Telematics.

Further reduce your operating costs with easy access to key checkpoints, the cooling system and other key components. Rely on excellent filter design, efficient air cleaner and centralized grease points.

Tier 4 Technology
To reach Tier emissions standards, the DX300LC-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).
