Product Description
Engineered with precision hydraulics delivering 75.6 L/min dual-pump flow and 28 MPa working pressure, this 2018 Doosan DX80 represents proven mid-size excavator technology. Built around the reliable Yanmar 4TNV98 engine producing 41.4 kW at 2100 RPM, this 8-ton machine combines robust performance with operational efficiency.
Key technical specifications demonstrate superior engineering:
- Bucket digging force: 56 kN with 0.30-0.32 m³ capacity
- Maximum digging reach: 6,350 mm with 4,165 mm depth capability
- Transport dimensions: 6,000 × 2,290 × 2,685 mm for versatile job site access
- Ground pressure: 37 kPa minimizing surface damage
- Fuel capacity: 145L supporting extended operation cycles
Located in Jiangxi Province, this DX80 showcases Doosan's joint-venture manufacturing quality from their Yantai facility. The 4-stroke, water-cooled direct injection system ensures consistent power delivery across demanding applications. With 30° climbing capability and dual-speed travel (4.9/3.1 km/h), this excavator handles diverse terrain conditions while maintaining productivity standards expected from professional construction operations.
