Doosan Launches DX165W-5 Short Tail Wheeled Excavator

The new 16.5 tonne DX165W-5 Stage IV compliant wheeled excavator from Doosan Bobcat EMEA is a short tail machine that is perfect for jobs in tight spaces, particularly in urban areas or on narrow roads with heavy traffic. Tailored to meet specific customer demands, the new DX165W-5 has been designed to ensure it offers the same high performance as the market-leading conventional Doosan wheeled excavator models.

Key features of the DX165W-5 include:

• A very short swing radius (1850 mm) combined with excellent stability for maximum performance and lifting capacities though an optimal centre of gravity and an ideal weight distribution.
• Extremely precise, powerful and smooth digging control required for trenching and lifting work, along with the acclaimed cab comfort, space and controllability of Doosan wheeled excavators.
• Extra power and strong design and construction together with the lowest fuel consumption and easy servicing, resulting in the best return on investment on the market.

Like all Doosan Stage IV machines, the DX165W-5 has a distinctive new machine styling scheme which heralds the many design advances that go well beyond simply meeting Stage IV emission regulations and setting a new benchmark for wheeled excavators worldwide.

Extra Compactness with Incredible Stability
The DX165W-5 is built with the same undercarriage as the DX160W-3 model, providing an optimal centre of gravity thanks to the long wheel base and the ideal weight distribution. The DX165W-5 also features a new generation of heavy duty ZF axles offering the best possible dynamic and static axle load. From the standpoint of performance, the DX165W-5 has the same forces and lifting capacities depending on the application as the DX160W-3 Stage IIIB model. The DX165W-5 can therefore lift 5.87 tonne at 4.5 m reach over the front (at 3 m high) and 4.28 tonne over the side. This is a better performance than any other short tail wheeled excavator in its class.

With a rear swing radius of only 1850 mm and a very small turning circle, the minimum swing diameter of the DX165W-5 when fully retracted is only 4.5 m, which greatly facilitates use of the machine in inner-city locations and in all other tight spaces.

Power and Fuel Efficiency
At the heart of the new DX165W-5 excavator is the well-proven 4-cylinder, turbocharged Perkins 1204F 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 1204F engine provides an output of 102.1 kW (137 HP) at 2200 rpm. As a result, the DX165W-5 is the most powerful short tail wheeled excavator in its class, but also offers a 10% increase in fuel efficiency compared to the DX160W-3.

New innovative and exclusive features have been introduced that reduce fuel consumption. Among these are the engine auto shut-off, which shuts down the engine after the machine has been idling for a specified time; 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 four work modes (E, S, P and P+).

Further fuel efficiency results from the electric fan clutch on the excavator 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.

Travel speeds in the DX165W-5 range from 3 to 37 km/h (depending on local regulations) with two speeds (high & low and creeping) plus cruise control. The DX165W-5 also has the largest hydraulic capacity in its class with the main pump flow delivering 2 x 171 l/min with a system pressure of 340 to 360 kg/cm2 increasing the efficiency of machine functions and also maximising versatility and precision, particularly when using high flow attachments.

Outstanding Comfort and Controllability
The ergonomic and comfort features offered as standard in the new ROPS certified cab 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 from the joystick or pedal.

The last feature is standard on all ‘-5’ machines and increases operator comfort when controlling attachments (like a shear or breaker) from the joystick for long periods or very repetitively. 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 highly sensitive and low-effort joysticks are combined with clear convenient controls to enable operators to work safely, smoothly and confidently with minimum effort for increased comfort, efficiency and productivity.

The operator also has the benefit of improved side visibility, a heated air suspension seat, 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 pressurised cab incorporates sealing, air filters and increased inside air pressure to prevent dust from getting into the cab (ISO 10263-3). Operators have access to all filters/oil vehicle information for maintenance prevention. Nine intervals can be entered manually and monitored and there are 13 different warning alerts. For more comfort and safety, the front axle oscillation can be automatically or manually activated for better lifting and digging.

Other important aspects include the ‘CabSus’ cab suspension system which reduces vibration and cab noise, further increasing safety and comfort for the operator.

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.

A floating boom system is available to increase productivity and reduce fuel consumption. This is ideal for levelling, truck loading, rock scraping and hammer work. In addition, it reduces the stresses and vibrations transmitted to the machine and work group. Two modes are available: a flotation mode that leaves the boom free to move upwards and downwards following bucket and arm movements and a breaker mode where the boom is free to move downwards to maintain optimum hammering effect and avoid excessive force. The front components automatically follow the breaker as it penetrates into rock and other surfaces.

CoreTMS Fleet Management System as Standard
In common with all Doosan Stage IV excavators above 14 tonne, the DX165W-5 is 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 ‘W-5’ wheeled excavators and customers are provided with their own account so that they can manage the machines in their fleet using the system.

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.

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.

The Engine Emergency Stop Switch is located on 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 arti boom, short and long arms, twin or single tyres and hydraulic lines are available for the new DX165W-5.
