New DX140W-7 and DX160W-7 Wheeled Excavators Launched
We are pleased to announce the launch of the new DX140W-7 and DX160W-7 Stage V compliant wheeled excavators. These 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.
New Operator Assist Features
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 (speed is zero), without the driver having to step on the brake pedal.
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 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.
New Tiltrotator Mode
There is 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 maximize the accuracy of tiltrotator work by eliminating back pressure.
Another standard new feature is the Fine Swing function which minimizes 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.
The cab on the DX140W-7 and DX160W-7 features as standard a deluxe steering wheel with a chrome plated spoke and logo. The new two spoke wheel design provides increased operator visibility. The steering column also has a new design including an 80 mm telescopic function, which allows the operator to bring the steering wheel closer to them, so that they can find their optimal driving position.
Other key new features in and around the cab include:
- New 8-inch Doosan Smart Touch screen, giving more information via a 30% larger screen
- DAB audio (Hands-free calling system and Bluetooth)
- Keyless start (Doosan Smart Key) & remote door lock/unlock
- Fully adjustable air suspension seat with heating (with optional cooling function)
- Parallel wiper system and new design pedals
- Improved air flow for defrosting and air conditioning
- Centre High Mounted Stop Light (CHMSL)
- 9 x LED work lights as standard
- 4 more LED lamps as an option
- AVM - Around View Monitor with 360° cameras (option)
- Ultrasonic detection of obstacles (option)
Enhanced Tool Carrier Capability
The DX140W-7 and DX160W-7 offer improved front movement for rotating tools such as mulchers and the working range for articulated fronts has also been improved. The articulated boom cylinder stroke has also been increased whilst the mounting position remains the same. A lock valve has now been added on top of the boom cylinder, to prevent unexpected releasing of the articulated boom cylinder when doing digging work.
The DX140W-7 incorporates a heavier 2.5 tonne counterweight as standard, for both monoboom and articulated boom configurations. The DX160W-7 is equipped with a 2.5 tonne counterweight as standard, but can be equipped with an optional 3 tonne counterweight. This contributes to the higher lifting and digging capacities in both the DX140W-7 and DX160W-7, compared to the previous generation models. With the optional 20% heavier counterweight, the DX160W-7 is particularly suited for working with heavier attachments such as tiltrotators.
