The company said that the new ‘-7’ models provide significantly higher performance in every area than the previous generation Stage IV machines.


“They combine novel operator assist features, enhanced comfort and increased tool carrier capability with new features to boost fuel efficiency, uptime and return on investment, with a focus on increased power, robustness and agility,” said Doosan Infracore.


“The state-of-the-art cab on the DX140W-7 and DX160W-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.”


The DX140W-7 and DX160W-7 wheeled excavators offer, as standard, the new ‘Auto Digging Brake’ feature, which automatically holds the service brake in position when the vehicle stops, without the driver having to step on the brake pedal. The driver can activate or deactivate the function by pressing a specific button on the control panel. When the accelerator pedal is then pressed, the Auto Digging Brake function is released.


‘Joystick Steering’ is a new option, enabling the driver to steer the machine by using the joystick thumbwheel, without using the steering wheel, when working and driving in the work mode. The Joystick Steering system only works under 20 kph when first or second speed gears are engaged. The function is activated or deactivated by pressing the thumbwheel steering button on the control panel for at least one second.


The ‘Load Isolation System’ (LIS) is another new option that enhances the operator’s driving comfort by mitigating the impact transmitted to the front of the machine, when driving off road on uneven and tough terrain. The Boom Suspension (LIS) function is also actuated by pressing a button on the control panel- it can be activated when the driving speed is 5 kph ±0.5 kph or higher, and the function is deactivated at 4 kph ±0.5 kph.


There is also a new Tiltrotator Mode on the control panel in the DX140W-7 and DX160W-7, which can be selected to ensure an optimized hydraulic flow and helps to maximise the accuracy of tiltrotator work by eliminating back pressure.


This new tiltrotator mode is a special two-way flow mode, but it is managed by the EPOS like a one way flow mode, with direct return to the tank in each direction, to avoid back pressure and increase flow and controllability.


Another standard new feature is the Fine Swing function which minimises the shaking that a lifted object undergoes at the start or stop of a swing movement with the excavator, to increase operator comfort with smooth movements and to help to protect the safety of nearby workers, whilst preventing damage caused by the object falling from the excavator.
