DX420LC-5 Doosan excavator specs & Dimensions (2016 - 2021)

Controllability

Exclusive jog shuttle switch, 4 work & 4 power modes, proportional control, user-friendly 7” TFT LCD colour monitor.

Easy maintenance

Easy access to all compartments. Radiator and oil cooler separated for better cooling and easier access. Maintenance data directly available from control panel.

TFT LCD colour monitor panel

The upgraded 7” Thin-Film-Transistor (TFT is a technology that improves image quality) LCD panel features a day and night display. The user-friendly monitor gives full access to machine settings and maintenance data. Any abnormality is clearly displayed on the screen, allowing you to work safely and confidently with an accurate overview of all conditions. All functions are totally controllable, directly via the screen or using the exclusive jog shuttle switch.

Power

Exceptionally powerful - with high torque at low revs - the Stage IV compliant Scania engines are free from Diesel Particulate Filter (DPF) and associated regeneration system for more fuel efficiency.

Efficient fuel management

This generation of Scania engines uses up to 10% less fuel. A new SPC (Smart Power Control) system, combined with settable engine shut-off, provides an additional reduction of up to 5%. 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 emissionsEngine auto-shut-off: shuts down the engine after the machine has been idling for a specified timeElectronic control of fuel consumption optimises efficiencyAuto-idle function saves fuelEco 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 efficientlySeparate radiator & hydraulic oil cooler assemblies: allows the hydraulically-driven oil cooler’s fan speed to be controlled by the electronics in order to maintain the optimum oil temperature and reduce noise & fuel consumption.

Dynamic power management

Automatic travel speed function. Activating the power boost control system increases digging force by 10%. A one-touch deceleration button immediately reduces engine speed to low or idle. Auto-idling starts 4 seconds after all controls are returned to neutral - decreasing fuel consumption and reducing noise levels in the cab.

4 Work modes & 4 Power modes

Deliver the needed power according to your specific application while minimising fuel consumption: 1-way mode, 2-way mode, Digging mode and Lifting mode. Power-plus mode, Power mode, Standard mode, Economy mode.

Advanced filtration

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 filters as standard minimise fuel system failures. Cyclonic air pre-cleaner: air filter life & engine efficiency are directly related to the amount of debris ingested through the engine’s air intake. Therefore, a cyclonic air pre-cleaner (as standard) is the first stage of an air intake system that prevents the majority of heavier-than-air particles from entering. Self-cleaning and maintenance-free, the system is able to expel all types of mixed debris, including mud, snow, rain, leaves, sawdust, chaff, etc.

Special applications

Our long-reach machines - with a reach of 16 & 19.6 metres - are ideally suited for special applications.

CORE TMS Doosan Telematic system

Is the technology of sending, receiving and storing information via telecommunication devices in conjunction with affecting control on remote objects. It will provide in a dual mode (Satellite, GSM) many details about the performances of your equipment such as operation hours, fuel efficiency, GPS, fault code/warning and reports.

Undercarriage durability

Forged steel and deep-hardened top rollers – oil-lubricated rollers – heat-treated sprocket – deep-hardened, heat-treated, grease lubricated & longer life track chains. The chain is composed of sealed, self-lubricating links for long-term dependability. For improved protection, alignment and performance, there are 3 types of guard - normal, double or full-length - according to the model. 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.

Extra-strong X-chassis

Designed using Finite Element Analysis and 3D computer simulation, the X-shaped undercarriage ensures optimum structural integrity and durability.

Reliability

Reinforced castings and forged steel pivot points and reinforced heavy-duty arm and boom to withstand high-impact materials. Large, robust boom and arm cylinders for smooth, powerful operation. Advanced pin & bushing technology.

Intelligent floating boom mode (optional)

The “intelligent floating boom” function allows the boom to move up & down freely according to application. Hydraulic breaker setting: during boom down operation the boom moves down freely under its own weight, which reduces vibration, stress on the machine & increases breaker life. Fully floating mode: during boom down selection the boom is allowed to rise & fall as required while the bucket is drawn across the ground.

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.

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 surface pattern and self-lubricating coating to optimise greasing and make removal of debris more efficient. Ultra-hard wear-resistant discs & bucket pivot polymer shim increase durability even more.

Comfort

One of the most spacious cabs in the market, with low noise & vibration levels and excellent all-round visibility. Fully adjustable heated air suspension seat, air conditioning with climate control as standard.

Heated air suspension seat (standard)

In addition to being adjustable and providing lumbar support, the seat has an air suspension system to reduce vibrations. It also features a seat heating system (activated at the touch of a button). A storage box has been placed under the seat for extra convenience.

Air conditioning with climate control

The operator can choose from 5 different modes to regulate the airflow, while the system adjusts the air temperature & fan speed to maintain the operator's selected temperature. A recirculated air function is also available.

Cab suspension system

The cab's new suspension system (CabSus mount) dampens high vibrations and provides outstanding protection against impact. The system absorbs shocks and vibrations much more effectively than a conventional viscous suspension system.

Safety

Rear camera and large side mirrors, powerful lighting, & anti-slip steps and platforms. Catwalk (except DX420LC-5). Guard rails on upper structure.

Your safety

Standard cab and boom lights, large side mirrors and rearview camera improve all-round visibility and thus safety. Other standard safety features: anti-slip plates, automatic overheating alarm warning, low oil pressure sensor, engine emergency cut-off switch, auxiliary mode switch (allows a safe level of hydraulics operation in case of EPOS failure), overload warning device. Optional travel/swing alarm and side view camera are also available.

Track guards

To provide better protection, track alignment, and performance of machine while travelling. 3 guards per track as standard for DX490LC-5 & DX530LC-5 (full-length track guard optional) and, for DX420LC-5, 2 guards per track as standard (double and full-length track guards available as options). These various track guard options provide you with optimal solutions for your extreme applications.
