Product Description
Built to handle the toughest excavation demands, this 2014 Doosan DH420LC-7 delivers 42-ton performance that integrates seamlessly into high-volume operations. Powered by a Doosan DE12TIS engine producing 210 kW at 2000 rpm, this crawler excavator maintains consistent productivity across extended job cycles. Currently located in Lishui, Zhejiang, the machine features a 6700mm boom with multiple rod configurations (2600/3250/4000mm) for versatile reach requirements.
- Operating weight: 41,200 kg with bucket capacity ranging 1.44-2.18 m³
- Maximum digging reach: 11,520mm / Maximum digging depth: 7,725mm
- Dual main pumps: 2 × 315 L/min for responsive hydraulic flow
- Bucket digging force: 242.1 kN standard / 264.6 kN supercharged
- Water-cooled system with 9.5 rpm rotation speed for continuous operation
For contractors managing multiple sites or requiring backup capacity during peak seasons, this DH420LC-7 offers proven joint-venture manufacturing quality from Yantai. The machine's 600mm track plates and 2750mm gauge provide stable footing across varied terrain, while the 3660mm rear turning radius enables efficient work in confined staging areas.
