Product Description
Engineered with Doosan's proven D34D engine platform, this 2017 DX120-9C delivers 71 kW at 1850 rpm, providing consistent hydraulic performance across demanding jobsite conditions. Operating at 12 tons with a 12,200 kg working weight, this mid-size excavator combines power density with fuel efficiency through its joint venture manufacturing standards.
Hydraulic performance defines this machine's capability:
- Bucket digging force: 99-105 kN with 0.51 m³ capacity
- Rod digging force: 63.2-67 kN for precision trenching
- Maximum digging reach: 7,620 mm with 5,150 mm depth
- Turning torque: 2,495 Nm for stable slewing operations
- Compact swing radius: 2,130 mm rear clearance
Dual travel speeds (4.5/2.8 km/h) optimize both transport efficiency and grading precision. With transport dimensions of 7,315 × 2,540 × 2,745 mm, this unit balances jobsite mobility with substantial reach capabilities. Maximum vertical digging depth of 3,605 mm suits utility installation and foundation work. Currently located in Luzhou, Sichuan, this DX120-9C represents Doosan's commitment to hydraulic reliability in the 12-ton excavator class.
