Product Description

Built for precision and operator confidence, this 2020 Doosan DH420LC-7 excavator delivers 42-ton performance with exceptional machine control. Powered by a Doosan DE12TIS engine producing 210 kW at 2000 rpm, this water-cooled workhorse combines robust digging force—242.1 kN bucket force and 218.5 kN arm force—with refined hydraulics that respond predictably under load. Dual 315 L/min main pumps ensure smooth, simultaneous functions across boom, arm, and swing operations.

  • Spacious cab positioned at 3,150 mm height offers commanding visibility across the 11,520 mm working envelope
  • Low 9.5 rpm swing speed enhances load stability and reduces operator fatigue during repetitive cycles
  • 540 mm ground clearance and 3,660 mm rear swing radius enable confident positioning on uneven terrain
  • Variable arm configurations (2,600/3,250/4,000 mm) adapt to trench work or mass excavation tasks
  • Hydraulic pilot controls with 24 L/min flow provide fingertip precision for delicate grading or truck loading

Currently located in Wenzhou, Zhejiang, this joint-venture manufactured machine represents proven Doosan engineering with 41,200 kg operating weight and 1.44–2.18 m³ bucket capaci
