Daewoo 225 Long Reach Excavator: Extending the Versatility of a 22-Ton Classic
The Daewoo DH225 series (and its successor, the Doosan DX225) has long been a benchmark in the 22-ton excavator class, renowned for its reliability, fuel efficiency, and smooth hydraulics. While it excels in general construction and earthmoving, there are scenarios where the standard 5.7m boom and 2.9m arm simply don’t provide enough reach. For these situations, converting a Daewoo 225 to a long reach configuration unlocks a new level of versatility.
Why Convert a Daewoo 225 to Long Reach?
The 22-ton class offers the perfect balance of portability and power. Adding a long front attachment to a Daewoo 225 creates a machine that can compete with larger excavators in specific applications, such as:
Canal and Pond Dredging: Clearing sediment and vegetation from waterways without the machine needing to enter the water.
Deep Utility Trenching: Excavating below the reach of standard booms for sewer, water, and gas lines.
Slope and Embankment Work: Profiling road and rail embankments from a safe, stable position on the shoulder.
Industrial and Scrap Handling: Extended reach allows for working over obstacles or reaching into deep bins and hoppers.
Technical Highlights of the Daewoo 225 Platform
The standard Daewoo DH225LC-7 is a robust machine with an operating weight of approximately 21,500 kg and a bucket capacity ranging from 0.5 to 1.28 m³. It is powered by the DB58TI engine, delivering 108 kW of reliable power, and offers a maximum travel speed of up to 5.4 km/h. This established platform provides an excellent base for a long reach conversion.
What a Long Reach Conversion Delivers？
While the standard configuration gives a maximum digging depth of approximately 7 meters, a long reach conversion can extend this significantly. Aftermarket manufacturers have offered long reach solutions for the Daewoo 225 that can achieve maximum digging depths of over 13 meters and maximum digging reaches approaching 15.5 meters. This dramatic increase in operating envelope allows the machine to tackle jobs that would otherwise require a much larger, more expensive unit.
Important Conversion Considerations
Structural Reinforcement: Extending the front places greater stress on the boom, arm, and turntable. A proper conversion uses reinforced steel and high-quality welding to handle the increased leverage and forces.
Hydraulic System Tuning: The Daewoo 225’s hydraulic system must be properly calibrated or fitted with a flow divider to ensure the long arm operates smoothly without sacrificing power or control.
Counterweight Requirements: A longer front shifts the machine’s center of gravity forward. Additional counterweight is typically required to maintain stability and prevent the machine from tipping at maximum reach.
Conclusion
The Daewoo 225 long reach conversion offers a cost-effective alternative to purchasing a larger machine for specialized deep excavation and high-reach projects. By extending the proven capabilities of the DH225 platform, operators can maximize their return on investment and take on a wider variety of challenging jobs.
