2. Power and Emission System

The DX150W-9C is equipped with the original Doosan DL06 6-cylinder water-cooled turbocharged intercooled diesel engine, adopting high-pressure common rail fuel injection technology and optimized combustion chamber design:

High power reserve and strong load adaptability, can operate stably in harsh environments such as high altitude (up to 4,000 m), high temperature (up to 52℃) and low temperature (down to -25℃).
3 optional working modes are available: Power (P) mode for heavy load operations such as rock digging and crushing; Standard (S) mode for daily construction to balance efficiency and fuel consumption; Economy (E) mode for light load operations such as material handling to reduce operating cost.
Equipped with automatic idle and auto shut-off functions, which reduce unnecessary fuel consumption and operating noise when the equipment is idle for a short time.

3. Hydraulic System

Doosan's mature hydraulic system optimized for wheeled excavators ensures high operation precision and response speed:

Main pump output flow reaches 2×140 L/min, matched with high-precision control valves, smooth compound action coordination (digging, swinging and traveling can be carried out simultaneously without lag, improving operation efficiency by 12% compared with the previous generation model.
Closed-circuit travel hydraulic system + four-wheel drive switchable design, strong climbing ability, can adapt to muddy, uneven off-road sites.
Wet disc brake system, maintenance-free within design life, reliable braking performance, ensuring safe driving on both public roads and construction sites.
Independent hydraulic oil cooling system keeps the system working temperature stable under long-term heavy load, extending the service life of hydraulic components.

4. Structural Design and Working Performance

Key structural parts (boom, arm, undercarriage frame) are made of high-strength alloy steel, with stress relief treatment after welding, strong impact resistance, service life extended by 20% under heavy load operation.
Wheeled walking design will not damage the paved road surface, can travel directly on public roads without flatbed transport, saving 30% of transfer time and cost compared with crawler excavators, especially suitable for scattered urban construction sites.
Supports a variety of optional attachments: breaking hammer, auger, log grapple, ripper, snow plow, etc., to meet the needs of road crushing, drilling, material handling, land clearing, snow removal and other diversified operations.

5. Operator Comfort and Safety

The cab adopts ROPS (Roll-over Protective Structure) and FOPS (Falling Object Protective Structure) certified safety design, which effectively protects the operator's safety in case of rollover or falling object impact.
Full adjustable air suspension seat + ergonomic low-effort control joystick, large-area sound insulation and heat insulation material, the internal operating noise is controlled below 75 dB, greatly reducing long-term operation fatigue.
7-inch full-color LCD instrument panel displays real-time working parameters, fault codes and mode information in real time, which is convenient for operators to grasp equipment status timely.
Large curved panoramic glass provides 360° no-blind-area vision, ensuring operation safety in crowded construction sites. It is also equipped with high-efficiency air conditioning, multiple storage compartments, USB charging ports and other humanized configurations.

6. Maintenance Convenience

All daily maintenance points are arranged at ground-accessible positions, no need to climb to the upper part of the equipment, saving 40% of daily inspection time.
Fuel filter, oil filter, air filter and hydraulic oil filter are centrally arranged on the same side of the fuselage, with long replacement cycle, reducing daily maintenance cost.
Equipped with the original DoosanCONNECT remote management system, which can monitor equipment location, working hours, fuel consumption and fault information remotely in real time, convenient for fleet managers to carry out asset management and pre-maintenance reminder, reducing equipment downtime.

7. Main Application Scenarios

The DX150W-9C is suitable for:

Urban municipal works: road repair, pipeline laying, greening construction, old building demolition
Logistics and freight yard: bulk material handling, container unpacking
Farmland water conservancy construction: channel dredging, farmland renovation
Emergency rescue: disaster relief, emergency road clearing, emergency engineering
Special operations: snow removal in winter, waste sorting, etc.

Overall, the Doosan DX150W-9C is an ideal choice for users who need frequent site transfer and diversified operation needs, with excellent comprehensive performance and low total cost of ownership.
