Brand: DOOSAN – A globally trusted South Korean heavy machinery brand, operating in over 140 countries. Renowned for robust engineering, cost-effectiveness, and user-centric design, its mid-tonnage excavators are favored for international construction, mining, and infrastructure projects, balancing power and reliability.
Model: DX225-7 – A flagship 22.5-ton class crawler excavator, designed as a versatile workhorse for medium-to-heavy intensity operations. It integrates strong power, industrial-grade durability, and intuitive operation, making it ideal for international building construction, road construction, mining, and large-scale earthworks.
Equipped with DOOSAN’s optimized 6-cylinder diesel engine (D6AC), featuring turbocharging and electronic fuel injection technology. It delivers a rated power of 110kW/2000rpm and strong torque output, easily handling hard soil, weathered rock, and bulk material loading. The intelligent power matching system adjusts fuel supply based on workload, reducing unnecessary consumption while maintaining operational efficiency—ideal for long-term overseas projects seeking cost savings. The engine meets global Tier 3 emission standards, ensuring compliance with international environmental regulations.
The boom and arm are constructed from high-tensile steel, with reinforced welding at stress points and integrated structural optimization to resist torsion and impact during heavy-duty operations. The standard 1.0m³ rock bucket (optional larger capacity) is lined with wear-resistant alloy steel, with replaceable bucket teeth and side cutters extending service life. The heavy-duty undercarriage features thickened track plates, sealed lubricated rollers, and reinforced idlers, adapting to rough mining terrain, muddy construction sites, and uneven roadbeds. Key components such as hydraulic cylinders and pipelines adopt high-pressure resistance designs, minimizing leakage risks and enhancing system reliability.
Adopts DOOSAN’s advanced load-sensing hydraulic system, ensuring smooth, coordinated movements and precise digging/loading operations. Whether handling composite tasks (digging, lifting, rotating) or grading complex slopes, the operation feels intuitive and stable. The cab is equipped with ROPS (Roll-Over Protective Structure) and FOPS (Falling Object Protective Structure) as standard, safeguarding operators in harsh conditions. The ergonomic adjustable air-suspension seat reduces fatigue during long shifts, while large panoramic windows and a rearview camera (standard) eliminate blind spots. The centralized digital display monitors real-time engine status, fuel level, and hydraulic pressure, with clear alerts for potential faults.
Maintenance points are centrally arranged for convenient access: the engine hood and side panels open wide, allowing easy reach to filters, oil fill ports, and hydraulic components. The large-capacity fuel tank and extended service intervals minimize downtime, while modular design of core components (engine, hydraulic pump) simplifies troubleshooting and replacement. DOOSAN’s global spare parts network covers major regions (Southeast Asia, Africa, Europe, Americas), ensuring fast delivery of common parts (bucket teeth, track links, filters) to remote job sites. The machine’s high adaptability to diverse working environments reduces wear and tear, lowering long-term maintenance costs.
DOOSAN’s iconic heavy-duty design, with a balanced weight distribution and sturdy frame for stable operation. The exterior is coated with anti-corrosion, anti-rust, and scratch-resistant paint, withstanding tropical humidity, desert dust, and cold temperatures—suitable for long-term outdoor work in diverse global environments.
The boom and arm feature reinforced structural design, with thickened steel at key stress points for enhanced load-bearing capacity. The standard 1.0m³ rock bucket is made of wear-resistant alloy, with replaceable bucket teeth and side cutters—ideal for digging hard soil, rock, and loading bulk materials. The articulated boom design ensures flexible movement in confined spaces.
The D6AC diesel engine runs smoothly with low noise and meets global Tier 3 emission standards for cross-border use. DOOSAN’s advanced hydraulic system delivers precise control and stable power output, ensuring efficient operation even during continuous high-intensity tasks. The integrated cooling system with oversized radiators prevents overheating in harsh environments.
The spacious cab features effective sound insulation and vibration damping, creating a quiet working environment. The adjustable air-suspension seat and automatic climate control system reduce fatigue during long shifts. The centralized control levers and clear digital display allow intuitive operation, while ROPS/FOPS protection and 360° visibility enhance operational safety.
The DOOSAN DX225-7’s versatility and power make it suitable for a wide range of international projects:
- Building Construction: Foundation excavation for residential and commercial buildings, backfilling trenches, and handling construction materials (sand, cement, steel).
- Road & Infrastructure: Highway and rural road subgrade digging, slope shaping, drainage system construction, and bridge pier excavation.
- Mining & Quarries: Surface soil stripping, ore loading, and aggregate handling in small-to-medium mines and quarries.
- Water Conservancy & Agricultural Projects: Irrigation canal excavation, reservoir construction, and large-scale farmland leveling.
We provide end-to-end support to simplify international procurement:
- Transparent Inspection Reports: Detailed documents covering mechanical performance (engine power, digging force), structural integrity, track wear, and safety component checks—with videos showing the machine in real operating scenarios.
- Customs Clearance Assistance: Expert help with preparing import documents (certificate of origin, emission compliance report, commercial invoice) and adapting to local regulations (e.g., import tariffs, safety certifications, environmental standards).
- Tailored Logistics Solutions: Flexible shipping options (ro-ro shipping for whole-machine transport, bulk shipping for spare parts) with anti-rust and anti-collision packaging. Real-time cargo tracking is provided until delivery to your construction site, with on-site assembly, commissioning, and operator training available if needed.
