Product Description
Engineered with Yanmar's proven 4TNV94L engine delivering 39.7 kW at 2200 rpm, this 2020 Doosan DX75 combines precision hydraulics with reliable Japanese powertrain technology. The variable piston pump system drives impressive digging forces—53.4 kN bucket force and 36.9 kN arm force—making it highly capable in demanding excavation applications across its 7-ton weight class.
Built as a joint venture model in Yantai, China, this machine demonstrates Doosan's commitment to engineering excellence through its compact yet powerful design. With a maximum digging reach of 6,270 mm and depth capacity of 3,930 mm, the DX75 offers exceptional working range for its size. The 0.28 m³ bucket capacity, paired with 10.7 rpm rotation speed and 30° climbing ability, ensures productive performance in confined jobsites.
Key technical specifications include:
- Working weight: 7,350 kg with 111L fuel capacity
- Compact transport dimensions: 6,030 mm (L) × 2,100 mm (W) × 2,680 mm (H)
- Dual travel speeds: 3.0/4.7 km/h for versatile mobility
- 370 mm ground clearance with 2,110 mm track contact length
Currently located in Shaoxing, Zhejiang, this unit represents proven mid-size excavator techn
