Product Description
Engineered with precision in Yantai, this 2019 Doosan DX75 delivers 7-ton performance through advanced hydraulic architecture and proven Yanmar power. The 4TNV94L engine generates 39.7kW at 2200rpm, paired with a variable piston pump system that produces exceptional digging forces: 53.4kN bucket force and 36.9kN arm force. Four-stroke water-cooled direct injection ensures consistent output across demanding jobsites.
Operational specifications demonstrate superior engineering:
- Maximum digging reach of 6270mm with 3930mm depth capability
- 10.7rpm rotation speed for efficient cycle times
- Compact footprint: 6030mm transport length, 2100mm width
- 30° climbing ability with 370mm ground clearance
- 111L fuel capacity supporting extended work shifts
- 0.28m³ bucket capacity optimized for versatility
Currently located in Sichuan, this joint-venture manufactured excavator combines Japanese engine reliability with Korean hydraulic expertise. Dual travel speeds (3.0/4.7 km/h) and minimal 1745mm front turning radius enable precision work in confined areas. Full technical documentation available for qualified buyers.
