Product Description
Engineered with precision in Yantai, this 2020 Doosan DX75 mini excavator delivers exceptional performance through superior hydraulic integration and proven mechanical design. Powered by a robust Yanmar 4TNV94L four-cylinder engine generating 39.7 kW at 2200 rpm, this 7-ton machine combines a variable piston pump system with optimized hydraulic circuits to produce 53.4 kN bucket digging force and 36.9 kN arm digging force—figures that outclass comparable models in its weight category.
Key technical specifications include:
- Operating weight: 7,350 kg with 0.28 m³ bucket capacity
- Maximum digging reach: 6,270 mm with 3,930 mm depth capability
- Rotation speed: 10.7 rpm for rapid cycle times
- Compact transport dimensions: 6,030 × 2,100 × 2,680 mm
- Dual travel speeds: 3.0/4.7 km/h with 30° grading ability
- 111-liter fuel capacity for extended operation
Currently located in Qingdao, Shandong, this joint-venture manufactured excavator represents Doosan's commitment to hydraulic efficiency and structural integrity in the compact excavator segment.
