Overview and Key Strengths

The Used Doosan DX300 Excavator is a heavy-class hydraulic excavator purpose-built for demanding construction, quarrying and mining tasks. This 2023 unit with 910 operating hours combines proven hydraulic performance, durable undercarriage design and a spacious operator environment to deliver consistent productivity on medium-to-large job sites.

Performance and Durability

Powered by a Doosan engine series and rated at 71 kW, the DX300 balances fuel efficiency with torque for heavy digging cycles. The machine’s 30-ton operating weight provides stability for high breakout forces and safe handling of large buckets and attachments. Key wear components — boom, arm, pins and undercarriage — are designed for straightforward inspection and maintenance, reducing downtime in long projects.

Versatility and Attachments

The DX300 supports a wide range of attachments including multiple bucket sizes, hydraulic breakers, grapples and quick couplers. Its reach of up to 8.16 m and digging depth of 5.65 m make it suitable for trenching, foundation excavation, material loading and light demolition. Configurable hydraulics let operators match flow and pressure to the chosen tool for optimal cycle times.

Operator Comfort and Safety

The cab layout prioritizes visibility and ergonomic control placement. Standard safety features include robust ROPS/ FOPS cab protection, good sightlines to the stick and bucket, and service access points that simplify daily checks. These design elements help reduce operator fatigue and improve overall site safety.

Who Benefits Most
