Product Description

Powered by a Doosan DE12TIS engine delivering 210 kW at 2000 rpm, this 2020 DH420LC-7 combines proven hydraulic architecture with exceptional digging performance. Operating at 41,200 kg working weight with dual 315 L/min main pumps, the machine generates bucket digging force up to 264.6 kN and rod force reaching 218.5 kN—engineered for high-production quarrying, deep foundation work, and mass excavation.

  • Hydraulic System: Parallel inclined axial piston pumps, 34.3 MPa boost circuit, water-cooled efficiency
  • Reach Capability: 11,520 mm maximum digging radius, 7,725 mm digging depth
  • Bucket Range: 1.44–2.18 m³ capacity with multiple rod configurations (2600/3250/4000 mm)
  • Mobility: 5.5 km/h travel speed, 3,660 mm rear swing radius, 600 mm track plates
  • Location: Wenzhou, Zhejiang Province

Built at Doosan's Yantai facility, the DH420LC-7 represents joint-venture manufacturing standards with consistent component sourcing. Current availability in Zhejiang offers regional buyers reduced logistics costs and faster deployment timelines.
