Technical Powerhouse and Fuel Efficiency

The mechanical heart of this Doosan DH300LC-9 is the turbocharged DE08TIS engine, known worldwide for its massive torque output and high thermal efficiency. This power unit delivers a consistent 147 kW, ensuring you have the digging power needed for dense clay or loose rock without engine derating. The advanced e-EPOS (Electronic Power Optimizing System) coordinates the engine speed and hydraulic pump flow with absolute precision, providing 4 distinct work模式 and 3 power modes to match every task perfectly. This intelligent synchronization allows the machine to achieve up to 15% better fuel economy in Eco-mode compared to earlier generations, a critical advantage for contractors in high-fuel-cost regions like Africa and the Middle East. The high-flow hydraulic system features dual axial piston pumps with a combined flow of over 400 L/min, ensuring smooth simultaneous coordination of the heavy-duty boom and 1.4 m³ rock bucket.

Reinforced Mining-Grade Structures

Built to withstand over 10,000 hours of continuous heavy-duty service, the DH300LC-9 features a reinforced mining-grade X-frame undercarriage and a heavy-duty boom/arm assembly constructed from high-tensile strength steel with internal baffle plates. The 'LC' (Long Undercarriage) configuration provides a significantly larger footprint than standard models, offering unmatched stability when lifting heavy loads or working on steep, unstable terrain. Every track link, roller, and sprocket on this unit shows virtually zero wear, verified by digital ultrasonic testing. Furthermore, the specialized high-ambient cooling package ensures that the engine and hydraulic oil remain within optimal temperature ranges even in extreme heat conditions up to 52°C (125°F).
