Product Description
Engineered with precision, this 2017 Doosan DX75-9C mini excavator delivers 39kW of reliable power through its Yanmar 4TNV98-EXS engine, operating at 2200 rpm with straight, naturally aspirated combustion. Built for demanding applications, the machine features a variable piston pump feeding robust hydraulic circuits at 3.9 Mpa, generating impressive bucket digging force of 53.4 kN and rod digging force of 36.9 kN. Operating at 7,420 kg working weight with a 0.3 m³ bucket capacity, this compact powerhouse combines maneuverability with serious performance.
- Maximum digging depth: 4,080 mm with 6,115 mm reach radius
- Axial piston rotary motor achieving 10.4 rpm swing speed
- Variable axial piston travel motors with dual-speed capability (4.5/2.8 km/h)
- 3,620 mm boom and 1,670 mm arm configuration for optimal geometry
- 111L fuel tank and 90L hydraulic reservoir for extended operation
- Compact transport dimensions: 6,030 mm × 2,180 mm × 2,680 mm
- Currently located in Chongqing, ready for global shipment
