Model: DOOSAN DX300LC-9C – A 30-ton class heavy hydraulic crawler excavator, a core model of DOOSAN’s 9C series optimized for large-scale earthwork, small and medium-sized mining and high-rise building foundation construction scenarios. Powered by the DOOSAN DL08 6-cylinder turbocharged engine (159kW rated power) and equipped with DOOSAN’s exclusive variable displacement piston pump hydraulic system, it delivers a working weight of 30,220kg, a standard bucket capacity of 1.45~1.6m³, and a maximum bucket digging force of 183.3kN. With a rear swing radius of only 3,188mm and multi-mode operation, it has been proven to operate continuously for over 10,000 hours without major failures in Middle Eastern mining areas, and is widely used in Africa, the Middle East and Central Asia for its fuel efficiency and high reliability.
The DX300LC-9C is equipped with the
DOOSAN DL08 6-cylinder turbocharged diesel engine (7.640L displacement, 159kW/1900rpm rated power), which adopts high-pressure common rail fuel injection technology and meets EU Stage II emission standards—perfectly adapted to emerging markets with relatively loose emission regulations. The engine delivers a maximum torque of 800N·m, ensuring strong power output in heavy-load scenarios such as rock excavation and mine loading, while the fuel consumption is only 28-32L per working hour, 18% lower than that of peers in the same tonnage class.
The
air intake optimization design with a double-layer air filter effectively blocks dust and sand in desert and mining areas, extending the engine’s service life to 12,000 hours—25% longer than the industry average. The engine compartment adopts a side-by-side heat dissipation device, avoiding overheating in high-temperature environments above 45°C, and the fuel pre-filter with oil-water separation function adapts to low-quality fuel in emerging markets.
Paired with DOOSAN’s
variable displacement piston pump hydraulic system (main pump maximum flow of 2×248L/min), the DX300LC-9C realizes fast and smooth composite operations. The hydraulic system features load-sensing control, ensuring digging force is not affected by load changes, and the bucket digging force of 183.3kN and arm digging force of 128.4kN can easily handle hard soil and rock materials.
The
optimized pump flow distribution control reduces hydraulic loss by 15%, while the independent circuits for the working device and steering system eliminate mutual interference during composite operations, improving work efficiency by 12% in earthmoving and loading scenarios. The hydraulic components adopt high-quality seals and wear-resistant materials, with a service life of up to 8,000 hours, and the modular design allows for quick replacement of parts in remote overseas sites.
The DX300LC-9C is equipped with DOOSAN’s exclusive EPOS intelligent control system and SPC intelligent fuel-saving technology, offering multiple customizable working modes to meet different operation needs:
- Standard Mode (S Mode): For general construction scenarios such as earthwork, with balanced power and fuel consumption.
- Power Mode (P Mode): For high-efficiency construction scenarios such as large-scale mining, with maximum power output.
- Economy Mode (E Mode): Prioritizing fuel saving for light-load operations such as grading and loading, reducing fuel consumption by up to 20%.
- Breaker Mode (B Mode): Optimized for hydraulic breaker operations, with stable oil flow control to protect the hydraulic system.The multi-functional LCD dashboard supports 10+ languages (including English, Arabic and Russian), displaying real-time data such as fuel consumption, engine speed and hydraulic pressure, and alerts the operator of maintenance and fault information. The dashboard also allows customization of operating parameters, adapting to different working conditions.
The ROPS/FOPS certified sealed pressurized cab prioritizes operator comfort and safety for long-hour overseas operations:
- Ergonomic Design: The cab features a spacious space (internal noise ≤70dB), a suspended adjustable luxury seat with armrests, and an optimized control lever layout, reducing operator fatigue during 8-hour+ continuous shifts. The air conditioning system with multiple air outlets maintains a comfortable temperature in the cab, adapting to temperatures from -10°C to 45°C, and the Bluetooth radio allows operators to listen to music and weather forecasts during work.
- Safety Protection: The cab adopts a high-rigidity tubular structure, withstanding impact from falling objects and rollover accidents. The large front and side windows provide 360° wide vision, ensuring safe operation in crowded construction sites such as urban infrastructure projects. The anti-slip floor mat and safety belt reminder function further enhance operational safety.
- Easy Maintenance: Daily maintenance points such as oil level, coolant and air filter are accessible at ground level, cutting maintenance time by 30%. The main frame and boom are equipped with standard LED work lights, improving night work efficiency by 40%, and common spare parts (filters, bucket teeth, hydraulic hoses) are available in DOOSAN’s regional warehouses in Dubai, Moscow and Johannesburg, with a delivery time of 7-15 days.
With overall dimensions of 10,615×3,200×3,515mm and a rear swing radius of 3,188mm, the DX300LC-9C has a sturdy and compact body. The anti-corrosion DOOSAN yellow paint resists salt spray in coastal construction areas and sand abrasion in desert mining areas, while the reinforced counterweight ensures stable operation during 30-ton heavy-load digging.
The DOOSAN DL08 engine (159kW rated power, 7.640L displacement) is neatly arranged in a sealed engine compartment with a side-by-side heat dissipation device for efficient heat dissipation. The double-layer air filter and fuel pre-filter with oil-water separation function adapt to harsh working conditions in emerging markets, ensuring long-term stable operation.
The variable displacement piston pump hydraulic system with a main pump maximum flow of 2×248L/min drives the 1.45~1.6m³ standard bucket to achieve a maximum digging radius of 10,702mm and a maximum digging depth of 7,275mm. The reinforced boom (6,245mm) and arm (3,100mm) are made of high-strength steel, withstanding heavy-load operations in rock excavation scenarios.
The sealed pressurized cab is equipped with a multi-functional LCD dashboard, an ergonomic joystick and an air conditioning system (cooling capacity 6kW), adapting to temperatures from -10°C to 45°C. The EPOS system monitor displays real-time machine status, and the waterproof switches and dust-proof seals suit rainy tropical regions in Southeast Asia and high-dust mining areas in Africa.
