DOOSAN DH220LC-9 Crawler Excavator

Overview

The Doosan DH220LC-9 is a 22-ton class heavy-duty crawler excavator developed and manufactured by Doosan Infracore, as a core model of its high-reliability 9-series excavator lineup. Designed for both light and heavy construction scenarios, it balances high operation efficiency, excellent fuel economy, and outstanding durability, making it one of the most popular medium-sized excavators in global markets for infrastructure, mining, and municipal construction projects. The "LC" in its name stands for Long Crawler, which delivers lower ground pressure and better stability on soft terrain.

2. Power System

The DH220LC-9 is equipped with a Doosan DL06K 6-cylinder, 4-stroke, turbocharged & intercooled diesel engine, compliant with Tier 3 / Stage IIIA emission standards:

Rated Power: 110 kW (148 hp) at 1,950 rpm
Max. Torque: 590 N·m at 1,400 rpm
Fuel Tank Capacity: 320 L
Features: Electronic high-pressure common rail fuel injection system optimized for low fuel consumption, delivering 10-15% better fuel efficiency compared to the previous DH220LC-7 model, with low noise and emission performance suitable for urban construction scenarios.

3. Hydraulic System

It adopts Doosan’s proprietary e-EPOS (Electronic Power Optimizing System) intelligent hydraulic control system, with load-sensing negative flow control technology:

Main Pump: 2 × variable displacement axial piston pumps
Total Maximum Flow: 2 × 216 L/min
System Working Pressure: 34.3 MPa
Features: Precise flow matching between power and hydraulic system ensures smooth compound actions (simultaneous boom lifting, arm swinging, and travel). It has 3 selectable work modes: Power mode for heavy-duty operations, Standard mode for general construction, Economy mode for light tasks to save fuel, plus an automatic idle speed reduction function to cut unnecessary fuel waste during standby.

Structural Durability & Operator Comfort

Durability Design

Working Device: The standard 5.7 m boom and 2.9 m arm are welded with high-strength tensile steel, with reinforced plates added at stress-concentrated positions, capable of bearing long-term heavy load impacts in mining and breaking scenarios.
Chassis & Frame: X-type integral welded lower frame with reinforced crawler beams, sealed and lubricated track links, support rollers and idlers extend service life by 20% compared to ordinary undercarriage designs. The long crawler design ensures excellent stability even when operating with large attachments on sloped terrain.

Operator Cabin

ROPS/FOPS certified safety structure, protecting operators from falling objects and rollover risks.
Spacious interior with fully adjustable shock-absorbent seat, ergonomic control levers, and a multi-function LCD monitor that displays real-time operation data and fault self-diagnosis alerts.
Cabin noise level is controlled below 75 dB(A) during operation, paired with a high-efficiency air conditioning system and 360° wide field of view, greatly reducing operator fatigue during long working hours.

Core Advantages

High Operation Efficiency: Optimized power-hydraulic matching delivers fast action response and strong digging force, with working efficiency 8% higher than peer products of the same tonnage.
Low Operating Cost: Extended maintenance intervals (engine oil change every 500 operating hours, hydraulic oil change every 5,000 hours), all daily maintenance points are arranged at ground-accessible positions to cut downtime and maintenance costs.
Strong Adaptability: Low ground pressure makes it suitable for soft soil, swamp and muddy construction sites; optional auxiliary hydraulic pipelines support a wide range of attachments to meet demands of different working scenarios.
