Doosan DH210W-7 Wheeled Excavator Detailed Introduction

The Doosan DH210W-7 is a 21-ton class mid-sized wheeled excavator developed and manufactured by Hyundai Doosan Infracore, tailored for high-mobility construction scenarios that require frequent site transfers without damaging paved surfaces. It inherits Doosan’s consistent advantages in high reliability, strong power output and low whole-life operation cost, and is one of the most popular wheeled excavator models in global engineering markets.

2. Power System

The DH210W-7 is equipped with a self-developed Doosan DL06 6-cylinder inline water-cooled diesel engine:

It has 25% low-rpm torque reserve, strong adaptability to high-altitude, high-temperature and heavy-load working conditions, and can work stably at an altitude of less than 3000m without power reduction.
The optimized high-pressure common rail fuel injection system reduces comprehensive fuel consumption by 5~8% compared with the previous generation of wheeled excavators, and the hourly fuel consumption is controlled at 12~16L under conventional working conditions.
Equipped with 3-stage heavy-duty air filter and dual-stage fuel filter, it adapts to low-quality fuel in remote construction sites and effectively extends the engine service life.
It supports three working modes that can be switched freely: Power (P) mode for heavy-load digging operations, Standard (S) mode for conventional earthworks, and Economy (E) mode for light-load finishing operations to maximize fuel efficiency.

3. Hydraulic System

It adopts a mature negative flow control hydraulic system, matched with first-tier brand main pumps and control valves:

The system response speed is 15% faster than similar products, the compound action of boom lifting, arm retraction and swing is smooth without jitter, and the operation efficiency is greatly improved.
It is equipped with an independent travel hydraulic circuit and wet disc brake system, which ensures stable driving and reliable braking on slopes up to 35°.
The standard auxiliary hydraulic circuit supports the expansion of various attachments such as hydraulic breakers, wood grabs, augers and sweepers, which meets diversified construction needs.

4. Structural Durability

The high-strength steel welded box-type chassis has been subjected to strict stress relief treatment, with strong impact resistance, and can adapt to uneven gravel and muddy construction sites.
The boom, arm and bucket are all made of high-tensile steel, and key stress positions such as welding joints and hinge points are reinforced. It has passed 10,000 hours of extreme load test, effectively avoiding structural deformation and cracking under long-term heavy load operation.
The standard engineering-grade wear-resistant rubber tires are matched with a hub reduction axle, which has strong load-bearing capacity, and the service life of the tires can reach more than 3000 hours under conventional pavement operation.
The whole machine is treated with electrophoretic primer and high-performance anti-corrosion topcoat, which can adapt to harsh working environments such as coastal humid and salt spray areas.

5. Operation Comfort & Safety

The cab meets ROPS (Roll Over Protective Structure) and FOPS (Falling Object Protective Structure) safety certification, with excellent sealing performance, and the internal noise during operation is controlled below 75dB(A).
It is equipped with a fully adjustable air suspension seat with lumbar support, which effectively reduces the fatigue of long-term operation. The ergonomic hydraulic joystick has light operating force and reasonable layout, and the operator can complete all operations without excessive arm movement.
The large-area panoramic glass provides 360° dead-angle-free vision, and the standard rear-view camera ensures the safety of driving and operation.
The multi-function LCD monitor displays real-time operating parameters such as fuel level, hydraulic oil temperature, operating hours and fault codes in real time, which is convenient for operators to grasp the equipment status. The cab is also equipped with automatic air conditioning, radio and USB charging ports to improve operation convenience.

6. Maintenance Convenience

All daily maintenance points including oil filter, fuel filter, air filter and oil dipstick are arranged at ground-accessible positions, no need to climb the upper frame for daily maintenance, which saves 40% of maintenance time.
The long maintenance cycle: engine oil replacement every 500 hours, hydraulic oil replacement every 5000 hours, air filter replacement every 2000 hours under conventional working conditions, which greatly reduces the whole-life maintenance cost.
The on-board intelligent diagnosis system can automatically detect equipment faults, and display fault codes and troubleshooting schemes on the monitor, which is convenient for maintenance personnel to eliminate faults quickly.

7. Main Application Scenarios

The DH210W-7 can travel directly on paved roads without damaging the road surface, and short-distance transfer does not require flatbed trucks, so it is widely used in:

Municipal engineering: trench digging, pipe laying, road repair, waste removal
Urban landscaping: site leveling, pit digging for tree planting, green belt trimming
Road maintenance: asphalt pavement removal, slope trimming, guardrail installation
Emergency rescue: debris cleaning, road opening, post-disaster reconstruction
General earthworks: foundation excavation, material handling, site clearing

Non flooded

No accident
