Doosan’s new crawler excavator simplifies transportation

Crawler excavator

Doosan Infracore North America is expanding its excavator lineup with the new 17-tonne DX170LC-5 crawler excavator.

The new model size allows for easier transportation, especially for small- to mid-size contractors who perform light excavation projects, such as digging residential basements or commercial building footings.

The crawler excavator reduces the need to obtain a special transport permit when moving to and from jobsites.

The width and combined weight between the machine, trailer and Class 7 towing vehicle meets current transportation requirements.

However, owners should still check local requirements when transporting equipment.

The DX170LC-5 excavator will be a step up from the smaller Doosan DX140LC-5 and DX140LCR-5 models, but it’s not as large as the DX180LC-5.

“We felt it was very important to offer a model in this size class to ensure our excavating customers could minimize transportation costs, while retaining the performance they expect from Doosan excavators,” said Aaron Kleingartner, Doosan Infracore North America marketing manager.

“The new model fits nicely in our crawler excavator lineup, giving our customers more options to suit their needs.”

As well, the DX170LC-5 offers many performance-driven features, including good visibility to the jobsite. Similar to current “dash 5” Doosan crawler excavators, the DX170LC-5 offers four power modes for more control to better balance fuel consumption and machine power to the working conditions.

Power modes include the following:

  • Power+ mode: Delivers the fastest workgroup speeds for loading trucks, top digging performance and extra power for digging in hard ground.
  • Power mode: Provides exceptional power and performance for tough digging conditions and truck loading tasks.
  • Standard power mode: Balances the excavator’s fuel consumption in everyday digging, grading and lifting tasks.
  • Economy mode: Reduces fuel consumption for low-demand applications and slows down machine movement for conditions that require extra precision.

To further match the machine to the application at hand, DX170LC-5 operators will be able to choose from four work modes — digging, breaker, shear and lifting — to maximize efficiency and fuel economy in specific applications. Operators can configure the work mode by adjusting a dial switch on the right-hand console.

A work mode icon displays on the monitor after the operator presses the mode button.

More news from Doosan:

Doosan crawler excavators come standard with a rearview camera, enhancing operator visibility on jobsites to help minimize damage to the machine and unnecessary downtime.

An optional sideview camera is also available. Camera views are easily accessible to operators on the 18 cm LCD screen mounted in the excavator cab. Operators have the option of a split screen to see both camera views at once.

Crawler excavator options

Factory-installed options for the new DX170LC-5 crawler excavator include:

  • Straight travel pedal, which allows the operator to travel in a straight line more easily.
  • Two-way auxiliary hydraulic pedal, in addition to joystick control.
  • Intelligent floating boom.
  • Cab guarding for special applications.
  • Sideview camera.
  • Additional work lamps.
  • Rotating beacon.
  • Air compressor.


The Doosan DX170LC-5 will come with a standard three-year subscription to the DoosanCONNECT telematics system, which allows equipment owners and fleet managers to remotely monitor machine location, hours, fuel usage, engine idle versus work time and error codes, as well as engine and hydraulic temperatures.

Machines can be monitored via an online account. In addition, Doosan dealers can provide improved customer support using the system by responding to machine warning messages and alerts, troubleshooting machine issues, and then sending a field service vehicle to help with repairs and deliver the proper parts.

Tier 4 solution

The Doosan DX170LC-5 crawler excavator complies with Tier 4 emission standards with modified diesel engine and aftertreatment technologies.

The engine is optimized for use with a high-pressure common-rail (HPCR) fuel delivery system and a cooled exhaust gas recirculation (CEGR) system.

The crawler excavators use a diesel oxidation catalyst (DOC) to reduce particulate matter and selective catalyst reduction (SCR) aftertreatment to reduce nitrogen oxides. Furthermore, a variety of aftertreatment systems have been implemented as part of Tier 4 compliance, such as DEF, which is used with SCR technology.
