Introducing the Next-Gen Doosan Wheel Excavators

Doosan Infracore North America is rolling out its next-generation -7 Series wheel excavators: the Doosan DX140W-7, DX190W-7, and DX210W-7. The “dash 7” excavators replace the “dash 5” models in the Doosan excavator lineup.

“Each day comes with unexpected challenges, so it’s critical that Doosan excavators are equipped with machine features that help our customers take on whatever comes their way,” says Joel Escalante, senior product specialist. “With our new wheel excavators, customers can achieve powerful digging and more maneuverability, all while reducing fuel consumption. We’ve also enhanced the excavator cab with additional comfort features and now offer an all-around view monitor camera system for even better visibility of the jobsite.”

Powerful Digging and Maneuverability

The new -7 Series wheel excavators have a modular design that allows owners to easily configure the machine’s undercarriage to level, backfill material with the front dozer blade or stabilize the machine when digging. Owners can choose from four independent outriggers or a front dozer blade and independent rear outriggers.

A wheel excavator customer can drive on the shoulder of a road to dig in an adjacent ditch or use a bucket with a hydraulic thumb or tiltrotator to pick up materials and load them into a truck for disposal. Plus, a one-touch power boost feature can be enabled to help amplify hydraulic power for digging in tough material. 

Maximize Productivity, Fuel Consumption With Smart Technologies 

The redesigned wheel excavators feature Smart Power Control (SPC) to improve machine efficiency while maintaining productivity through variable speed control and pump torque control. Each of the four power modes will function with SPC engaged or disengaged. However, SPC is only active in the digging work mode. 

Four work modes, auto idle, auto shutoff, and machine diagnostics help wheel excavator owners manage their fuel costs. In addition, each machine is equipped with engine auto shutdown to save fuel and help lower warranty hours.

Improved Visibility and Comfort

The redesigned Doosan wheel excavator cab offers more floor space, automotive-style heating and air conditioning, and excellent visibility through the front, rear and overhead windows. Inside the cab is an optional deluxe air-suspension seat that is heated and cooled, ergonomically designed joystick controls and a new 8-inch Smart Touch screen. 

The multilingual Doosan Smart Touch screen, standard on -7 Series excavators, displays settings and information on one screen. From the touch screen, operators can monitor machine functions and control machine settings, rearview camera, heating and cooling, radio and Bluetooth® wireless technology.

All-Around View Monitoring (AVM) System

The optional 360-degree all-around view monitoring (AVM) camera system displays a full view of the machine’s surroundings. Five unique visual perspectives can be seen from the separate AVM monitor: top view, rear view, top+right view, rear+corner view, and 3D view. The AVM camera system can be linked with optional ultrasonic detection sensors for an additional level of awareness of objects behind the machine.

New Machine Offerings

The optional load isolation system engages automatically at 3.1 mph (5 km/h), reducing attachment and machine bouncing when traveling on uneven road surfaces. The standard auto hold brake system engages the digging brake automatically while the fine swing function reduces the shock from excavator swing starts and stops. An optional trailer-ready feature allows wheel excavator operators to pull a 5- to 10-ton trailer. In addition, a tilt-rotator working mode and a priority valve enable the use of mulchers, grass cutters and other specialty attachments.

Four Selectable Power Modes

Doosan offers four selectable power modes for more control over the excavator’s performance and to reduce fuel consumption. 

• Power+ mode for severe digging conditions and mass loading (top loading)
• Power mode for extremely deep trenching and simultaneously truck loading
• Standard power mode for general ground utility applications: digging and pipe laying
• Economy mode for precise grading and to maximize controllability and machine efficiency

DoosanCONNECT Telematics

The DoosanCONNECT Telematics system comes standard on all -7 Series wheel excavators to remotely monitor and maintain machines. DoosanCONNECT Telematics is an equipment diagnostic tool that monitors the health, location, and productivity of Doosan construction equipment from a mobile app and website.
