DOOSAN DH220LC-9 Crawler Hydraulic Excavator Detailed Introduction

The Doosan DH220LC-9 is a classic 22-ton class medium crawler excavator developed and manufactured by Doosan Infracore (now part of HD Hyundai Infracore), belonging to Doosan’s high-reliability -9 series product line. It is designed for balanced performance of heavy-load operation, fuel efficiency and long service life, and is widely used in infrastructure construction, mining, municipal engineering and other scenarios globally.

1. Engine & Hydraulic Performance

Power System

It is equipped with a Doosan DL06 6-cylinder, 4-stroke, turbocharged intercooled diesel engine, with a rated power of 110 kW (148 HP) at 1950 rpm. The engine meets Tier 3/China Stage III emission standards (Tier 2 version is available for emerging markets), features low speed and high torque output, and adapts to high altitude, high temperature and harsh working environments.

Hydraulic System

Adopts Doosan’s proprietary EPOS (Electronic Power Optimization System), which dynamically matches the output of the engine and the dual axial piston hydraulic pumps in real time, reducing unnecessary power loss by 6~9% compared with previous generation models. The system has a maximum total flow of 440 L/min, the slewing speed reaches 11.5 rpm, and the response speed of the working device is 15% faster than similar products in the same class.

Core Operation Performance:

Standard bucket capacity: 0.92~1.2 m³
Maximum bucket digging force: 152 kN
Maximum arm digging force: 112 kN
Maximum travel speed: 3.2~5.5 km/h
Gradeability: 35° (70%)

2. Structural Durability

The "LC" in the model name stands for long crawler chassis, with a ground pressure of only 0.47 kg/cm², which can operate stably on soft ground, muddy and low-bearing capacity sites:

The X-type central frame of the undercarriage is integrally welded with high-strength low-alloy steel, which has strong torsional resistance and impact resistance, and has a service life of more than 15,000 hours under heavy-load working conditions.
The boom and arm are reinforced with thickened steel plates and built-in stiffeners, and the bucket is made of wear-resistant manganese steel with forged tooth seats, which is suitable for hard rock excavation and quarry operations.
The track rollers, carrier rollers, idlers and drive sprockets are all subjected to high-frequency quenching treatment, which effectively reduces wear and extends the replacement cycle.

3. Operator Cabin & Control

The cabin is certified by ROPS (Roll-over Protective Structure) and FOPS (Falling Object Protective Structure), which fully guarantees the safety of operators:

The internal noise is controlled below 70 dB(A), with a fully adjustable air-suspension seat, and the pilot control handle has a light operating force, which reduces the fatigue of long-term operation.
The 5-inch color LCD instrument panel displays real-time parameters such as fuel consumption, water temperature, hydraulic oil pressure and fault codes, which is convenient for operators to grasp the equipment status.
The large-area curved glass design reduces the blind area of vision by 20%, and the high-efficiency air conditioning system, USB charging port and large storage space improve the comfort of operation.

4. Maintenance & Cost Efficiency

All daily maintenance points are arranged at ground-accessible positions, and the replacement of oil filters, fuel filters, air filters and other consumables can be completed without climbing the car, reducing the maintenance time by 30%.
The extended maintenance interval: engine oil replacement every 500 hours, hydraulic oil replacement every 5000 hours, pilot filter replacement every 1000 hours, which reduces the later use cost.
The automatic idle function and intelligent power control mode reduce the comprehensive fuel consumption to 13~16 L/h, which is 5~8% lower than similar products in the same class. Doosan's global after-sales service network and sufficient spare parts supply also ensure the high residual value of second-hand equipment.

5. Application Versatility

The DH220LC-9 can be matched with a variety of auxiliary tools to meet diversified operation needs:

Standard configuration for earthwork excavation, road construction, municipal engineering, water conservancy construction
Equipped with hydraulic breaker for demolition and hard rock crushing
Equipped with grapple, log grab for bulk material handling and forestry operations
Equipped with ripper for frozen soil and hard ground loosening
