Product Description
Engineered with precision hydraulics and a proven Yanmar 4TNV98-ZCV engine, this 2018 Doosan DX88-9C delivers 44.4 kW at 2100 rpm through a straight, naturally aspirated configuration. Dual variable piston pumps supply 2 × 70.4 L/min maximum flow, powering exceptional bucket digging force of 5.55 tons and rod force of 4.05 tons—critical metrics for demanding excavation tasks.
Operating at 7,970 kg working weight, this 8-ton compact excavator combines maneuverability with robust performance. Key specifications include:
- Maximum digging reach: 6,500 mm with 4,170 mm depth capability
- 0.38 m³ backhoe bucket capacity paired with 3,820 mm boom and 1,700 mm arm
- Compact transport dimensions: 6,300 × 2,340 × 2,680 mm
- Efficient fuel system: 135 L tank with 106 L hydraulic reservoir
- Dual-speed travel: 4.9 km/h high / 3.1 km/h low via axial piston hydraulic motors
Currently located in Nanning, Guangxi, this joint venture-manufactured machine represents Doosan's commitment to engineering excellence, offering reliable performance for contractors requiring precision excavation in confined spaces.
