Heavy-Duty Used Doosan DX300 Excavator 30 Ton Mining Grade with DL08 Engine 10m Digging Depth

The used Doosan DX300 is a 30-ton hydraulic crawler excavator built for the toughest jobs in mining support, quarry operations, and large infrastructure construction. Under the hood sits the Doosan DL08 diesel engine, a powerplant engineered for high torque at low engine speeds, giving the machine excellent fuel economy even under continuous heavy loading. The DX300 measures 10.62 meters in length, 3.34 meters in width, and 2.96 meters in height, with a maximum digging depth of 10 meters and a dumping height of 3.5 meters. This particular unit has been inspected and tested, with all hydraulic functions operating smoothly and the undercarriage in good condition. For contractors stepping up from 20-ton class machines, the DX300 delivers a noticeable jump in productivity.

• Doosan DL08 Engine: High-torque six-cylinder diesel engineered for heavy workloads, low fuel consumption, and long service intervals.
• 30-Ton Operating Weight: Superior digging force and stability for mining, quarrying, and heavy earthmoving applications.
• 10 m Maximum Digging Depth: Deep excavation capability for trenches, foundations, and water management projects.
• Large Capacity Bucket: High-volume bucket shortens loading cycles and increases daily production rates.
• Reinforced Front Structure: Heavy-duty boom and arm with extra plate thickness for continuous production work.
• Advanced Hydraulic Control: Fine metering and low-flow-loss design give operators precise control for finishing work.

The DX300 excels in open-pit mine support, aggregate quarry loading, large-diameter pipeline installation, and heavy construction projects such as bridges and dams. Its deep digging capability makes it particularly valuable for water reservoir and canal excavation, while its high dumping height allows efficient loading of large dump trucks. The machine also handles demolition work effectively when fitted with a hydraulic breaker, making it a versatile flagship unit for medium-to-large contractors.

Before shipment, the DX300 undergoes a full functional test including boom, arm, bucket, swing, and travel operations under load. It is then cleaned, serviced, and loaded on a 40-foot flat rack or via RO-RO vessel according to your logistics preference. We provide complete export documentation and a pre-shipment video tour of the machine. Our after-sales engineers accompany the delivery with online support for assembly and commissioning, and we can arrange shipping of genuine Doosan spare parts together with the machine to reduce your logistics costs.
