Doosan unveil new Stage IV-compliant crawler excavator
Latest 21-tonne DX225LC-5 machine offers high performance and increased fuel efficiency
DOOSAN Bobcat EMEA have launched the new DX225LC-5 – a 21-tonne crawler excavator offering a combination of high performance, operating features, fuel efficiency, reliability and durability.
Featuring a distinctive new machine styling scheme common to all new Doosan LC-5 generation excavators, the DX225LC-5 is powered by a six-cylinder, turbocharged Doosan DL06P water-cooled diesel engine, providing a power output of 124kW (166hp) at 1,800 rev/min.
The DX225LC-5 unit also offers convenience and lower costs by meeting Stage IV emission regulations through the use of cooled exhaust gas recirculation and selective catalytic reduction after-treatment technologies.
As well as the DL06P engine, which is said to be one of the most reliable and fuel efficient ever produced by Doosan, other new innovative and exclusive features have been introduced to the DX225LC-5, providing an overall 9% increase in fuel efficiency.
Among these features is: a new trip meter setting screen that allows operators to check fuel consumption daily (or over a desired period) directly from the control panel; an auto shut-off function that provides automatic shutdown for the engine after a pre-set time when the machine has been idling for a specified time; and a special Doosan-developed Smart Power Control (SPC) system that optimizes the balance between the pumps’ output and diesel engine.
The DX225LC-5 model is factory-installed with Doosan Connect – a new state-of-the-art wireless fleet-monitoring system that provides machine performance information via satellite or GSM.
The Doosan Connect system – also available for retrofits – is supplied with a free three-year subscription on all new LC-5 excavators above 14 tonnes in which customers are provided with their own account so that they can track/manage machines across their fleet using the system.
Already spacious and ergonomic, the new cab in the DX225LC-5 is bigger than the previous DX225LC-3 model and has been further refined for superior operator comfort and ease of operation. The cab offers greater 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 while 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 setup.
The joysticks have also been shortened to reduce the effort required to operate them and an additional pedal for straight travel has been installed on the left of the main travel pedals – a useful feature when travelling straight over longer distances. The operator console has been moved on to the seat suspension to reduce vibrations, giving the driver much better control via the joystick during demanding operation.
