The power to raise productivity
Máy đào bánh xích Doosan DX420LC-5 takes even the heaviest tasks in its stride with efficient, dependable performance that saves you time and money:
- Improved hydraulic system uses the engine power more effectively, maximising pump output and offering more comfort, smoothness and accuracy
- Increased digging power, lifting capacities and traction force combine for performance you can rely on, day after day
- Greater fuel efficiency means you can keep costs down and reduce environmental impact
OPTIMISED POWER MANAGEMENT
Máy đào bánh xích Doosan DX420LC-5 is equipped with a Perkins engine. Famous for excellent fuel efficiency, reliability and long service life, it combines exceptional power output and high torque at low revs. Engine is fitted with common rail fuel injection combined with an wastegate turbocharger which increases the density of the air enabling the engine to produce more power.
Selective Catalytic Reduction (SCR) technology - combined with a Diesel Oxidation Catalyst (DOC) - ensures compliance with Stage IV regulations. As there is no need for a particulate filter, there is no need for regeneration.
If the engine is the heart of the excavator, the e-EPOS is its brain - providing a perfectly synchronised communication link between the engine’s ECU (Electronic Control Unit) and the hydraulic system. A CAN (Controller Area Network) system enables a constant flow of information between engine and hydraulic system, so that power is delivered exactly as needed.
EFFICIENT FUEL MANAGEMENT
Choice between 4 power modes and 4 working modes guarantees optimum performance in all conditions
SPC (Smart Power Control): reduces engine RPM during low load demand & ensures pump torque control, thus ensuring fuel efficiency and low emissions
Engine auto-shut-off: shuts down the engine after the machine has been idling for a specified time
Electronic control of fuel consumption optimises efficiency
Auto-idle function saves fuel
Eco guidance in real time: eco gauge provides information about fuel consumption relative to machine performance in real-time. By trying to keep the right-hand LED bar from rising, the operator can teach himself how to save fuel and work efficiently
For optimum cooling, fan speed is controlled by a viscous clutch resulting in a lower fan noise & better fuel efficiency
Wastegate turbocharger: Allows diverting of exhaust gases away from the turbine wheel to better regulate max boost pressure & protect engine. It also results in less lag time before turbo begins to spool/create boost maximizing torque, plus reduce wear in high rpm & low load conditions. Turbocharger increases the density of the air, enabling the engine to produce more powerwith few effects from altitude.
Electronic viscous fan clutch: For optimum cooling, fan speed is controlled electronically by a fan clutch, resulting in lower fan noise and better fuel efficiency.

Reliability, the habit of a lifetime - MÁY ĐÀO DOOSAN DX420LC-5 HOẠT ĐỘNG BỀN BỈ, TUỔI THỌ CAO
Designed for long-term all-round heavy duty performance
In your profession, you need equipment you can depend on. At Doosan, we use highly specialised design and analysis tools to make sure our machines are as robust and durable as can be. Our materials and structures undergo stringent testing for strength and resilience under the most extreme conditions. And we continually manufacture the most durable machines to ensure lower cost of ownership.
Designed using Finite Element Analysis and 3D computer simulation, the X-shaped undercarriage ensures optimum structural integrity and durability.
The chain is composed of sealed, self-lubricating links for long-term dependability
The track spring and idler are joined for long-lasting performance and easy maintenance
Cast steel heavy-duty sprockets guarantee the highest resistance
Track rollers lubricated for life
Strengthened boom & arm
Finite Element Analysis has been used to calculate the best load distribution throughout the boom structure. Combined with thicker material, this means that element fatigue is limited and both reliability and component life are increased. To better protect the base of the arm, reinforced bars have been added and the arm centre and end boss have been strengthened.
Fuel filters & water separator: a filter-type high-performance water separator effectively captures moisture in the fuel, reducing impurities and helping minimise any fuel-related issues. Pre-filters and dual main
Air cleaner: the large capacity forced air cleaner removes over 99% of airborne particles, reducing the risk of engine contamination and making the cleaning and cartridge change intervals greater
Pin & bushing advanced technology
Highly lubricated metal is used for the boom pivot to increase the component's lifetime and lengthen greasing intervals. The bucket pivot features EM (Enhanced Macrosurface) bushings, which have a tailored
Sturdy & reinforced dozer structure:
- Wide angles of lifting height and digging depth to fit any working site
- Big anchor points for a maximal durability
- Large protection of the cylinders & hoses
- Lifting eyes on dozer for secure transport
- Parts in contact with the ground have been carefully designed to prevent damage to the surface
