Doosan's new DX170W-7 Wheeled Excavator offers a host of redesigned features and new technologies to ensure smooth operation, superior productivity and stability, top-class operator comfort and improved fuel efficiency. This powerful machine will give your job site a huge boost.

Advanced disc brake system

The new improved system allows a more efficient braking of the machine. This eliminates the rocking effect associated with working on wheels. The ZF axles are designed for low maintenance, and the oil change intervals have been increased to 2000 hours, further reducing owning and operating costs.

Pin and bushing advanced technology

Highly lubricated metal is used for the boom pivot to increase the component’s lifetime and lengthen greasing intervals. The bucket pivot features EM (Enhanced Macrosurface) bushings. These have a tailored surface pattern and self-lubricating coating for optimized greasing and more efficient debris removal. Ultra-hard wear-resistant discs and bucket pivot polymer shims increase durability even more.

New Doosan Engine

Exceptionally powerful – with high torque at low revs – the new Doosan engine combines reliability and low environmental impact. This Stage V compliant 6 cylinder engine delivers 152 hp at 2000 rpm.

Full Control Over Fuel Consumption

The latest evolution of the legendary Stage V Doosan DL06V engine, with significantly improved fuel economy thanks to a new travel mode using the flow of 2 pumps, automatically adjusts the required engine power and engine rpm to avoid lost energy. Take full control over your fuel consumption with a settable engine shut off and the automatic Smart Power Control (SPC). Easy on your wallet and the environment.

Efficient Fuel Management

Choice of 4 power modes (Eco - Standard - Power - Power Plus) and automatic Smart Power Control system for optimal power and reduced fuel consumption in all conditions. The Smart Power Control (SPC) system reduces engine speed and adjusts pump torque according to work conditions. It automatically adjusts engine power and hydraulic output to improve fuel efficiency and reduce emissions. A new traveling mode, using the flow of the 2 hydraulic pumps, reduces the engine rpm and fuel consumption. The engine auto-shut-off feature shuts down the engine after the machine has been idling for a specified time, and the operator can set the delay before shut-off via the Doosan Smart Touch screen.

Variable Pressure Turbocharger

Provides optimal air flow to the engine combustion chamber under all speed and load conditions, ensuring that exhaust gas is cleaner and fuel economy is improved.

New Drive Line Concept

The new travel motor and powershift transmission control in the drive line provide comfortable travel due to increased smoothness, improved hydraulic retarding, and improved gear shifting. A new travel mode, using the flow of 2 pumps, automatically adjusts the required engine power and rpm to avoid lost energy and provide the best fuel consumption.

Advanced Filtration

Fuel filters and water separator: a filter-type high-performance water separator effectively captures moisture in the fuel, reducing impurities and helping minimize any fuel-related issues. Pre-filters and dual main filters as standard achieve a high degree of purity that minimizes fuel system failures. The cyclonic air pre-cleaner, which is standard, is the first stage of an air intake system that prevents the majority of heavier-than-air particles from entering. Self-cleaning and maintenance-free, the system is able to expel all types of mixed debris, including mud, snow, rain, leaves, sawdust, and chaff.

Total control

Enjoy significantly reduced shock and better productivity when handling loads. Thanks to our switchable Fine Swing feature, you avoid bumps at the start and end of any boom movement (only recommended on flat surfaces). To increase accuracy, engage the Tilt Rotator mode, which enables smart distribution of hydraulic flow to eliminate back pressure.

4 work modes and 4 power modes

These modes deliver the needed power, according to your specific application, while minimizing fuel consumption: With the 2-way mode, we offer a priority valve on the attachment line to increase the machine's productivity when using an attachment and moving the arm at the same time. Engage the Tilt Rotator mode for increased accuracy by enabling smart distribution of hydraulic flow to eliminate back pressure.

Hydraulic system

The e-EPOS (Electronic Power Optimising System) is the brain of the excavator – minimising fuel consumption and optimizing the efficiency of the hydraulic system for all working conditions. To harmonize the operation of the engine and the hydraulics, the e-EPOS is connected to the engine's electronic control unit (ECU) via a data transfer link. The hydraulic system enables independent or combined operations 2 travel speeds offer either increased torque or high speed Cross-sensing pump system for fuel savings Auto-deceleration system 4 operating modes. 4 power modes Flow and pressure control of auxiliary hydraulic circuits from control panel Computer-aided pump flow control.

Comfortable ride

Bumpy terrain ahead? We have you covered. Our switchable Load Isolation System largely mitigates the impact of bumps on the cab. You enjoy a smooth ride, increased productivity and improved safety even on bumpy ground.

Cab Suspension

The cab's suspension system (CabSus mount) dampens vibrations and provides outstanding protection against impact. This system absorbs shocks and vibrations much more effectively than a conventional silentblock suspension system.

Hydraulic cylinders

High-strength steel piston rods and cylinder bodies. Shock-absorbing mechanism fitted in all cylinders for shock-free operation and extended piston life.

Swing mechanism

The swing mechanism uses an axial piston motor, driving a 2-stage planetary reduction gear bathed in oil for maximum torque. Swing bearing: single-row, shear type ball bearing with induction hardened internal gear Internal gear and pinion immersed in lubricant Increased swing torque reduces swing time The swing brake for parking is activated by spring and released hydraulically.

Drive

The wheels are driven by a bent axial piston engine via a 2-speed powershift transmission. In addition to the 2-speed powershift transmission there is also an economy mode and a switch for the creep speed. A button makes it possible to pass from high to low in work mode. Two travel speed ranges offer a choice between increased torque or high speed.

Easy maintenance

Maintenance data are directly available from the control panel. Easy access to filters from ground level. To protect coolers and minimize downtime, the cooling compartment is equipped with fine mesh for the intake air. These innovations make maintenance operations a pleasure.

Reliability – the habit of a lifetime

In your profession, you need equipment you can depend on. At Doosan, we put durability and reliability at the core of our machines’ development. Our materials and structures undergo stringent testing for strength and resilience under the most extreme conditions.

Strengthened boom and arm

During the development of our machines, we use intensive testing to calculate the best load distribution throughout the boom structure. Combined with thicker material, this means that element fatigue is limited and both reliability and component life are increased. To better protect the base of the arm, reinforced bars have been added and the arm center and end boss have been strengthened.

Doosan buckets

4 More. More choice - More durable - More strength - More performance! The General purpose bucket is designed for digging and re-handling soft to medium materials (e.g. materials with low wear characteristics such as top-soil, loam, coal). The Heavy duty bucket is designed for mass excavations in dense materials such as hard packed clay, shot limestone, limited rock content and gravel. The Severe duty bucket is designed for durability in digging compact materials like loose or blasted rock, hard packed clay and stone. The X-treme duty bucket is designed as a long-life version of the Severe duty bucket for digging in the most abrasive materials.

Lifting capacities

Lifting capacities are in compliance with ISO 10567:2007(B). The load point is at the end of the arm. The nominal loads are based on hydraulic capacity. The nominal loads shown do not exceed 75% of tipping loads or 87% of hydraulic lifting capacity. For lifting capacity with bucket, simply subtract the actual weight of the bucket from the values. The configurations indicated do not necessarily reflect the standard equipment of the machine.
