Product Description
Engineered for precision and reliability, this 2018 Doosan DX80 excavator delivers exceptional performance in the 8-ton class. At its core sits the proven Yanmar 4TNV98 VDB24 engine, generating 41.4 kW at 2100 rpm through a robust 4-cylinder, water-cooled direct injection system. Hydraulic efficiency defines this machine, with dual main pumps flowing 75.6 l/min each plus an auxiliary 18.7 l/min circuit, operating at 28 MPa across both travel and working systems.
Performance specifications demonstrate superior capability:
- Bucket digging force: 56 kN with rod force of 41 kN
- Maximum digging reach: 6,350 mm with 4,165 mm depth capacity
- Operating weight: 7,900 kg with 0.30-0.32 m³ bucket capacity
- Ground pressure: 37 kPa for minimal site disturbance
- Climbing ability: 30° gradient capability
Built through joint venture manufacturing in Yantai, China, this unit combines Doosan's engineering standards with practical jobsite durability. Currently located in Guizhou, the DX80 offers compact dimensions (6,000 mm transport length) while maintaining a 1,800 mm rear swing radius for confined workspace efficiency. Dual-speed travel at 4.9/3.1 km/h ensures productive cycle times
