Doosan introduce the DX225LC-5 excavator

New Stage IV-compliant machine offers performance, reliability and durability in the 21-tonne class  

DOOSAN Bobcat EMEA have recently launched the new Stage IV-compliant DX225LC-5 crawler excavator, which is said to offer 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 124kW (166hp) at 1,800 rev/min.  

In addition, the DX225LC-5 is said to offer very good performance levels in terms of speed, traction force and slew torque, while also delivering extra lifting capacity compared with other machines in the 21-tonne market.

The DX225LC-5 meets Stage IV emission regulations through the use of cooled exhaust gas recirculation (EGR) and selective catalyst reduction (SCR) after-treatment technologies, without the need for a diesel particulate filter (DPF), unlike some of the other 21-tonne machines on the market.  

As well as the fuel-efficient DL06P engine, other new innovative and exclusive features have been introduced to provide 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 the Doosan-developed Smart Power Control (SPC) system, to optimize the balance between the pumps’ output and the diesel engine.

The DX225LC-5 is factory-installed with the new DoosanConnect state-of-the-art wireless fleet monitoring system, providing comprehensive information about machine performance in a dual mode (satellite and GSM). This is supplied with a free three-year subscription in new LC-5 excavators above 14 tonnes.

The new cab in the DX225LC-5 is bigger than that in the previous DX225LC-3 and has been further refined for operator comfort and ease of operation. Features offered as standard in the cab include super controllability with a new system that allows 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.  Also, the operator console has been moved on to the seat suspension to reduce vibrations, giving the operator much better control with the joystick in rough operations.

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 have also added protection to the inner cab air filter and redesigned the cab air-conditioning filters for easier replacement.
