DOOSAN has announced the launch of its new 25-tonne DX245NHD-7 crawler excavator.
Described by the manufacturer as being designed for the ‘most abrasive’ of applications, the machine features 30-tonne class undercarriage components, with the chains, rollers, sprocket and chassis all ‘oversized’ to increase working lifetime.
Stephane Dieu, excavator product specialist at Doosan, explained, “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 2.54m.”
New features in and around the cab include the 8-inch Doosan Smart Touch, DAB audio (Handsfree and Bluetooth), smart key, leatherette heating seat, parallel wiper system, new design pedals, and eight LED work lights as standard. Optional extras include four more LED lamps, Around View Monitor (AVM) with 360° cameras, and ultrasonic sonic detection of obstacles.
To meet Stage V emission regulations, the DX245NHD-7 is powered by a Doosan DL06V diesel engine, providing 131 kW (176 HP) at 1800 RPM.
The model also boasts a heavy 5.0 tonne standard counterweight, said to be particularly suited for working with heavier attachments such as tiltrotators. The heavier counterweight also contributes to higher lifting and digging capacities.
Doosan added that a smart hydraulic system offers an improvement of around 30% in attachment work when compared to previous excavator models.
There is a tiltrotator mode, which can be selected to ensure an optimised hydraulic flow and helps to maximise the accuracy of tiltrotator work by eliminating back pressure. Another standard new feature is the Fine Swing function, which Doosan explained minimises the shaking that a lifted object undergoes at the start or stop of a swing movement.
