Mining-Grade Used Doosan DH300LC-7 Excavator 30 Ton with DB08TIS Engine 10m Digging Depth

The used Doosan DH300LC-7 represents the previous generation of Doosan's celebrated 30-ton excavator family, and it remains a favorite among operators who value proven mechanical simplicity and rugged build quality. Equipped with the Doosan DB08TIS engine, this machine delivers dependable power with straightforward, serviceable design that keeps maintenance costs low over the long term. The DH300LC-7 offers a maximum digging depth of 10 meters and a dumping height of 3.5 meters, with a blade width of 3.5 meters available for grading and backfilling duties. This unit has been checked by our workshop team, and the engine starts easily, the hydraulics respond crisply, and the track assembly shows even wear across all components.

• Doosan DB08TIS Engine: Time-tested powerplant with mechanical injection, easy to maintain in remote locations without dealer support.
• 30-Ton Class Performance: Full-size excavator power for heavy construction, mining support, and quarry operations.
• 10 m Digging Depth: Deep digging envelope suitable for pipelines, foundations, and drainage channels.
• 3.5 m Blade Width: Integrated dozer blade option for grading, backfilling, and site cleanup tasks.
• Proven LC Undercarriage: Long-track configuration delivers superior stability and flotation on soft terrain.
• Cost-Effective Ownership: Simple mechanical systems mean lower repair costs and easier parts sourcing than newer electronic machines.

The DH300LC-7 is well suited for general contracting, road construction, mining auxiliary duties, and large agricultural land reclamation projects. The optional dozer blade adds versatility, allowing one machine to handle both excavation and site grading, which is a major advantage on remote projects where mobilization costs are high. Its mechanical engine and proven hydraulics make it a favorite in developing markets where workshop facilities are basic and operator skill levels vary.

We prepare the DH300LC-7 for export with a complete service overhaul: all fluids replaced, filters renewed, track tension adjusted, and the machine test-run under load for 30 minutes. Loading is arranged on a 40-foot flat rack or by RO-RO, depending on your port requirements. You will receive photos and videos before shipment, and our team provides after-sales technical support by video call during machine commissioning. We can also supply matched spare parts kits including filters, hoses, and seals to accompany your order.
