New Doosan DX140W-5 and DX160W-5 Wheeled Excavators offer outstanding class-leading performance

Like all Doosan Stage IV compliant machines, the new DX140W-5 14 tonne and DX160W-5 16 tonne wheeled excavators from Doosan Bobcat EMEA feature a distinctive new machine styling scheme marking the many design advances they incorporate, which go well beyond simply meeting Stage IV emission regulations and set a new benchmark for wheeled excavators worldwide.

The new DX140W-5 and DX160W-5 wheeled excavators provide significantly higher performance in every area than the previous generation Stage IIIB machines, combining enhanced comfort and controllability together with new features to boost fuel efficiency, uptime and return on investment, with a focus on increased power, robustness and agility.

Both new models have the same 6-cylinder Doosan engine and power outputs as the Stage IIIB machines, but have 5% more traction force, ensuring superior performance compared to both of the previous generation machines. Another important aspect of the new ‘-5’ models is the ‘CabSus’ cab suspension system which reduces vibration and provides a 1 dBA reduction in cab noise, further increasing safety and comfort for the operator.

Outstanding Comfort and Controllability

The operator also benefits from the ergonomic and comfort features offered as standard in the new cab on the DX140W-5 and DX160W-5 wheeled excavators, which are among the best on the market and include the world exclusive Doosan jog shuttle switch; four work and four power modes; control of pressure and flow of the auxiliary lines directly from the operator’s seat; and joystick and pedal proportional control with super controllability via short and low stroke joysticks and a new system allowing usage of the two-way lines either via the joystick or pedal.

This last feature is standard on all ‘-5’ machines and provides an alternative to controlling attachments (like a shear or a breaker) solely via the joystick, which may become uncomfortable after several hours or following continuous repetition and thus increases operator comfort. It is also helpful when precision is required – as the operator can keep full control of the excavator via the joystick while using the two-way pedal for attachments.

The operator also has the advantage of improved side visibility, a new user-friendly 7 inch FT LCD colour monitor control panel, a fully automatic climate control system, more storage compartments for paperwork and other items, as well as an improved layout with the most important switches grouped together within easy reach on the right console. The new pressurised cab incorporates sealing, air filters and increased air pressure inside to prevent dust from getting into the cab (ISO 10263-3).

CoreTMS Fleet Management System as Standard

In common with all Doosan Stage IV excavators above 14 tonne, the DX140W-5 and DX160W-5 are factory-installed with the new CoreTMS state-of-the-art wireless fleet monitoring system. Designed specifically for the Doosan range, the CoreTMS system is a new tool providing comprehensive information about machine performance in a dual mode (satellite, GSM).

Because the software in the CoreTMS system has been upgraded to communicate directly with the EPOS system on a Doosan excavator, it is the only tool of its type capable of providing this level of information, delivering insightful and cost-saving data about equipment to help customers work more effectively. Also available for retro-fitting in a kit form, the CoreTMS system is supplied with a free 3-year subscription in new Doosan ‘-5’ excavators and customers are provided with their own account so that they can manage the machines in their fleet using the system.

No Diesel Particulate Filter

At the heart of the new DX140W-5 and DX160W-5 excavators is the well-proven 6-cylinder, turbocharged Doosan DL06P water-cooled diesel engine which offers convenience and lower costs by meeting Stage IV emission regulations without the need for a diesel particulate filter (DPF), through the use of cooled exhaust gas recirculation (EGR) and selective catalyst reduction (SCR) after-treatment technologies. The DL06P engine provides power outputs of 102.2 kW (137 HP) and 113.3 kW (152 HP) at 2000 rpm, respectively, in the DX140W-5 and DX160W-5 excavators.

As well as the DL06P engine, which is one of the most reliable and fuel efficient ever produced by Doosan, new innovative and exclusive features have been introduced that reduce fuel consumption by an average of 10% compared to the previous generation models. Among these features is the new ‘Trip Meter Setting’ screen which allows operators to check fuel consumption daily (or over a desired period) directly from the control panel and to save even more fuel, there is a special Doosan-developed system, Smart Power Control (SPC), which monitors both engine and pump power and limits unnecessary outputs depending on whether the work is light or heavy. The SPC can be used with all 4 work modes (E, S, P, P+).

Further fuel efficiency results from the electric fan clutch on both models, which drives the cooling fan at optimum speed. Based on coolant, hydraulic oil, cooled charged air temperatures and target engine speeds, the fan speed is controlled electrically – resulting in much lower fan noise and better fuel efficiency.

A side-view camera is available as an option and the control panel allows the views from both the rear and side view cameras to be combined on the same screen, simply by pressing a button on the control panel. For more safety when using the cameras, a menu bar now stays open so that the operator can keep an eye out for warning symbols and the levels of key gauges. New boom lights on the front equipment more than double the lighting available and for better protection, a guard has been added as standard.

The auto-idling rpm on the DX140W-5 and DX160W-5 automatically increases from 800 rpm to 1100 rpm when the temperature goes below 10 °C. This boosts the efficiency of the heating inside the cab.

Lower Total Cost of Ownership

In the undercarriage, the chassis frame has been reinforced to reduce stress and improve durability. The outrigger frame has also been strengthened by moving to a box type assembly, with an increase in the thickness of most parts for additional strength. The dozer blade and H-Link have been reinforced to increase rigidity and optimise tightening between the two structures. The height of the dozer blade has been increased along with an improved shape to facilitate pulling and mixing of materials. The size of the outrigger covers has been reduced to lessen the possibility of damage.

Made from cast steel, the arm end boss and arm link boss and side plates have been combined to increase durability. Piping layouts have been redesigned to avoid interferences between hoses and pipes, decreasing pressure loss as a result. The twin tyre rubber spacer has a new symmetric design and a new tight rim connection ensures no bending and a good connection to withstand impacts from stones/other materials.

To further maximise durability and reduce noise, all ‘-5’ models are equipped with EM (Enhanced Macro-surface) bushings, which are also much more effective than regular bushings when greased.

Air pre-cleaners are fitted as standard on all ‘-5’ wheeled excavators, to blow much of the dust, dirt, insects, rain and snow out of the air intake, to ensure cleaner air is sent to the engine air filter. This extends air cleaner servicing intervals, enhancing uptime and productivity. Doosan has also added protection to the inner cab air filter and redesigned the cab air-conditioning filters for easier replacement.

To avoid permanent engine damage, an acoustic alarm has been added to call the operator’s attention to ‘water in fuel’. If the operator ignores the signal after several alerts, the engine and pump are automatically derated. In addition, to make it easier for operators to understand the importance of warnings and to communicate the proper warning codes, pop-up menus appear with detailed information with easier to identify warnings.

The Engine Emergency Stop Switch has been relocated at the side of the seat so that it is directly accessible from ground level, for faster access in case of emergency. Star-shaped anti-slip plates ensure that the steps stay much cleaner and more effective and to meet new EU regulations, safety bars are installed as standard.

All current options including mono bloc and arti boom, short and long arms and hydraulic lines are available for the new DX140W-5 and DX160W-5.
