Doosan has launched the new DX245NHD-7 25 tonne heavy duty crawler excavator, a completely new model in the Doosan range, designed for the most abrasive of applications.
Whilst it is a real 25 tonne excavator, the DX245NHD-7 incorporates 30 tonne class undercarriage components - the chains, rollers, sprocket and the chassis itself are oversized to increase the working lifetime of the machine, even on the toughest jobs.
Stephane Dieu, excavator product specialist at Doosan, said: “The DX245NHD-7 adds a new highly sturdy option in the medium-sized range of crawler excavators from Doosan. With regard to the name of the machine, the ‘N’ stands for ‘Narrow Track’ and the ‘HD’ stands for ‘Heavy Duty’ illustrating its suitability for the most challenging applications. Complementing this, the ‘narrow’ design of the DX245NHD-7 offers the further advantage of a transportation width of only 2.54 m.”
Complementing the robust build, the state-of-the-art cab on the DX245NHD-7 excels in terms of spaciousness and ergonomics, taking operator comfort and ease of operation to new levels. As well as a new high quality seat, the enhanced cab offers more features as standard than other machines on the market, ensuring super controllability and high precision in all applications.
To meet Stage V engine emission regulations, the new DX245NHD-7 excavator is powered by the latest generation Doosan DL06V diesel engine, providing 131 kW (176 HP) at 1800 RPM. The DL06V engine offers a new solution to exceed Stage V regulations without exhaust gas recirculation (EGR), that boosts the quantity of air available during combustion, increasing the temperature of the process and greatly reducing the amount of particulates produced.
This is combined with super-efficient DOC/DPF+SCR after-treatment technology to ensure minimal emissions. Thanks to the new technology, maintenance of the diesel particulate filter (DPF) has been greatly reduced, with no maintenance required until the machine has operated for 8000 hours.
