New High Performing Doosan DX225LC-5 Excavator

 

Doosan Bobcat EMEA has launched the new Stage IV compliant DX225LC-5 crawler excavator, offering an unmatched combination of high performance, operating features, fuel efficiency, reliability and durability in the 21 tonne excavator class.

 

Presented in the distinctive new machine styling scheme common to all new Doosan LC-5 generation excavators, the DX225LC-5 is powered by the well-proven 6-cylinder, turbocharged Doosan DL06P water-cooled diesel engine, providing a high power output of 124 kW (166 HP) at 1800 RPM.

 

 

The DX225LC-5 therefore combines plenty of power with high torque at a lower number of revolutions, ensuring higher reliability over time than other 21 tonne machines, which have 4-cylinder engines running at much higher revs.  In addition, the DX225LC-5 offers very good performance levels in terms of speed, force and noise, especially the traction force and slew torque which are much higher than those in other machines, while also delivering extra lifting capacity compared to other machines in the 21 tonne market.  Machine noise (2000/14/EC, ISO 6395) has been reduced by 1 dBA.

 

Trouble-free Operation

 

The DX225LC-5 offers convenience and lower costs by meeting Stage IV emission regulations through the use of cooled exhaust gas recirculation (EGR) and selective catalyst reduction (SCR) after-treatment technologies.  With the DL06P engine, the DX225LC-5 ensures trouble-free performance as it operates without a DPF, unlike some of the other 21 tonne machines on the market.

 

As well as the DL06P engine, which is one of the most reliable and fuel efficient ever produced by Doosan, new innovative and exclusive features have been introduced providing an overall 9% increase in fuel efficiency.  Among these features is the new ‘Trip Meter Setting’ screen which allows operators to check fuel consumption daily (or over a desired period) directly from the control panel and to save even more fuel, there is a special Doosan-developed system, Smart Power Control (SPC), to optimise the balance between the pumps’ output and the diesel engine.

 

The Auto Shut-Off feature saves on fuel and warranty hours.  When the feature is enabled, the engine shuts down after it has been idling for a specified amount of time (3-60 minutes, configurable by the operator).

 

The DX225LC-5 is factory-installed with the new Doosan Connect state-of-the-art wireless fleet monitoring system, providing comprehensive information about machine performance in a dual mode (satellite, GSM).  Also available for retro-fitting in a kit form, the Doosan Connect system is supplied with a free 3-year subscription in new LC-5 excavators above 14 tonne and customers are provided with their own account so that they can manage the machines in their fleet using the system.

 

Already excelling in spaciousness and ergonomics, the new cab in the DX225LC-5 is bigger than that in the previous DX225LC-3 and has been further refined for outstanding operator comfort and ease of operation.  The features offered as standard in the cab are among the best in the market and include super controllability with a new system that enables attachments to be operated from either the joystick or a two-way pedal.  The operator can select 10 pre-set configurations for attachments and hydraulic flow and pressure data can be pre-selected directly from the control panel, allowing a quick change of attachments without the need for a manual set-up.

 

The joysticks have also been shortened to reduce the effort required to operate them and an additional pedal for straight travel has now been installed on the left of the main travel pedals, a very useful feature when travelling straight over longer distances.  The operator console has been moved onto the seat suspension to reduce vibrations.  This gives the operator much better control with the joystick in rough operation.

 

Lower Total Cost of Ownership

 

Like all new LC-5 excavators above 20 tonne, the DX225LC-5 incorporates a thicker inside plate in the arms and booms, providing front reinforcement to relieve stress concentration and a different welding method has also been applied.  To further maximise durability and reduce noise, all LC-5 models are equipped with EM (Enhanced Macro-surface) bushings, which are also much more effective than regular bushings when greased.

 

Air pre-cleaners are fitted as standard on the DX225LC-5, to blow much of the dust, dirt, insects, rain and snow out of the air intake, to ensure cleaner air is sent to the engine air filter.   This extends air cleaner servicing intervals, enhancing uptime and productivity.  Doosan has also added protection to the inner cab air filter and redesigned the cab air-conditioning filters for easier replacement.

 

All current options including narrow tracks, short and long arms, shoes and hydraulic lines are available for the new DX225LC-5.  A new Trimble Ready option is also available, enabling a faster and simplified installation of Trimble® 2D or 3D Grade Control System components − with no welding, repainting, drilling or disassembly required.
