The new DX255LC-5 is an extra 500kg heavier than the LC-3 model but delivers 17% more lifting capacity over both the front and side and a 1 dBA reduction in sound levels.
At the heart of the new excavator is the well-proven 6-cylinder, turbocharged Doosan DL06P water-cooled diesel engine.
This meets Stage IV emission regulations without the need for a diesel particulate filter, through the use of cooled exhaust gas recirculation and selective catalyst reduction after-treatment technologies.
The DL06P engine provides an output of 141 kW (189 HP) at 1900 rpm, an increase of 5% in engine power.
Along with several other features this has helped to reduce fuel consumption further by an average of 4% to 9% compared to the DX255LC-3 model, says Doosan.
Operators can check fuel consumption daily directly from a new Trip Meter Setting screen and pre-set a new automatic shut down for the engine after the machine has been idling for anywhere between 3 to 60 minutes.
Further fuel savings of around 4% are won by the Smart Power Control, to optimise the balance between the pumps’ output and the diesel engine.
The new excavator is factory-installed with the new CoreTMSwireless fleet monitoring system, now standard in all new LC-5 generation machines above 14t.
