The adoption of a rotor type pre-cleaner has increased filtering efficiency.
The sprocket structure and tooth have been strengthened to prevent debris and increase durability.
CENTRALIZED FUEL FILTRATIONS
The water separator, pre-fuel filter and main filter are located in one place to provide greater convenience and ease of maintenance, guaranteeing longer engine life as well
ELECTRIC FUEL TRANSFER PUMP [ETP] (OPTIONAL)
The adoption of pump switch enables easy refueling of the machine after inspection or repair
The fuel water separator filters out water from fuel, enhances the engine’s durability, and reduces quality problems caused by the presence of water in fuel (Extra Filter + Pre Filter + Main Filter).
INDUSTRY-LEADING PERFORMANCE AND PRODUCTIVITY
Best-in-Class Productivity with Unparalleled Lifting Capacity and Machine Stability. The DX12 is a whole new mechanical engine built on. Doosan’s continuously evolving engine technology. Its quality and durability have been significantly improved against the previous engine, delivering greater maximum engine output through various system improvements, and thereby reducing the engine’s workload during machine operation.
Doosan has also improved the engine’s components to eliminate any possibility of failure in the field. The improved design and materials of key components such as the engine block, cylinder head and piston has extended the engine’s lifespan to a significant extent. The new engine represents a breakthrough to even greater operational comfort, safety and productivity.
Excavator control improved by the New EPOSTM system. As the brain of the hydraulic excavator, the EPOSTM (Electronic Power Optimizing system) has been improved and perfectly synchronized with the newly adopted CAN (Controller Area Network) communication link.
How the DX420LCA-K performs has a direct impact on productivity. The combination of a newly improved engine and a redesigned EPOS-driven hydraulic system with an attractive cost-performance ratio is unrivalled by any other hydraulic excavators in its class.
Incomparable Lifting Capacity. The counterweight and undercarriage are built on the solid structure of this huge and powerful machine to create the best lifting capacity in its class.
Manufactured with surprisingly strong materials and structures, the DX420LCA-K is unrivalled in durability and safety, allowing it to pass rigorous performance tests under extreme conditions. Whenever you work in a tough environment, you can count on Doosan’s DX420LCA-K
HEAVY DUTY BOOM & ARM
With its state-of-the-art computer-aided design technology, Doosan’s machines are manufactured from highly durable materials and adopted structural design, enabling the machines to pass rigorous performance testing under the harshest conditions.
- Center Boss Plate - Size increased.
- Boom End Bracket - Single piece of casting type.
- Arm Bottom Plate - Increase plate thickness.
- Arm Side Plate - Increased plate thickness
- Arm Back Plate - Reinforced bar.
- Heavy Duty Bucket - New bucket with effective design
- Boom Plate - Increased boom foot height and decreased width, increased plate thickness
The boom pivot is made with a highly lubricated metal to increase the lifespan and extend greasing intervals to 250 hours.
ABRASION-RESISTANT ARM END DISK
New disks have been adopted to increase wear resistance and service intervals
INTEGRATED TRACK SPRING AND IDLER
The track spring and idler have been joined directly for even greater durability and improved maintenance convenience.
DX420LCA-K is equipped with a relief cutoff system that automatically detects excess hydraulic pressure in the cylinder and controls it by redirecting a portion of the hydraulic flow running into the cylinder back to the main pump, thereby eliminating the risk of cylinder damage due to excess pressure. The Relief Cutoff function ensures that the DX420LCA-K is permanently maintained in the optimal state.
DX420LCA-K is equipped with the Auto Idle function which automatically puts the engine and pump into the Standby mode when it detects a pause during operation. This function helps reduce fuel consumption by lowering idling RPM
PUMP MATChING TEChNOLOGY
Engine and pump matching, a new Doosan technology, fully resolves such problems as the low response time of the system and unnecessary fuel consumption. Matching the response time between pump and engine efficiently reduces unnecessary fuel consumption as well as reducing exhaust fumes.
More space, wider visibility, better air conditioning, and a very comfortable seat - all these elements allow the operator to work safely and comfortably for long hours in the best possible conditions.
3 power modes for maximum efficiency: Power mode, Standand mode, Economy mode
3 work modes to suit your application: 1-way mode, 2-way mode, Digging mode.
Levelling operations, the movement of lifted loads and tricky maneuvers are all controlled easily and precisely with the control levers. The buttons integrated into the levers can also be used to operate additional equipment such as grabs, crushers and grapples and to activate the power boost function.
REAR VIEW CAMERA (OPTIONAL)
AIR CONDITIONING WITH CLIMATE CONTROL
The high-performance air conditioning adjusts and electronically controls the flow of air according to the work conditions. The choice of five operating modes will keep even the most demanding operator happy and satisfied.
Short maintenance operations at long intervals increase the machine’s availability onsite at all times. DOOSAN has developed the DX420LCA-K to deliver even higher profitability to the customer.
Access to the various radiators is very easy, making cleaning easier. Access to the various parts of the engine is from the top and via side panels.
ENGINE OIL FILTER
The engine oil filter offers a high level of filtration allowing the oil change interval to be increased to 500 hours. It is easy to access and is positioned to avoid contaminating the surrounding environment.
PC MONITORING (DMS)
A PC monitoring function enables connection to the EPOSTM system, allowing various parameters to be checked during maintenance, such as pump pressures, engine rotation speed, etc. and these can be stored and printed for subsequent analysis.
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.
Install rotor type pre-cleaner (Donaldson Top Spin 5”). So filtering efficiency 20% increased
High efficiency and large capacity water separator protect the engine by removing most moisture from the fuel (additional water separator as strandard)
CENTRALIZED GREASE INLETS FOR EASY MAINTENANCE
