A look to the new Doosan DX170LC-5 Crawler Excavator

Doosan is expanding its crawler excavator lineup with the new DX170LC-5 excavator. The 17-metric-ton model falls below the 80,000 gross vehicle weight rating limit for simplified and less expensive transportation.

This new Doosan® excavator 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. This model reduces the need to obtain a special transport permit when moving to and from job sites. The width and combined weight between the machine, trailer and Class 7 towing vehicle meet current transportation requirements. Owners should still check local requirements when transporting equipment.

“Load ratings vary from state to state, so owners still need to check federal, state and local laws and regulations regarding weight, width, length, and height of a load before making preparations to transport their machine on public roads, bridges, highways, and interstates,” says Aaron Kleingartner, Doosan Infracore North America marketing manager.

The DX170LC-5 excavator will be a step up from the smaller Doosan DX140LC-5 and DX140LCR-5 models, but it won’t be 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,”

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

Performance Features

In addition, the DX170LC-5 will offer many performance-driven features, including good visibility to the job site. Similar to current “dash 5” Doosan crawler excavators, the DX170LC-5 will offer four power modes for more control to better balance fuel consumption and machine power to the working conditions.

    Delivers the fastest workgroup speeds for loading-trucks, top digging performance and extra power for digging in hard ground.
    Provides exceptional power and performance for tough digging conditions and truck loading tasks
    Balances the excavator’s fuel consumption in everyday digging, grading and lifting tasks.
    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.

Doosan crawler excavators come standard with a rearview camera, enhancing operator visibility on job sites to help minimize damage to the machine and unnecessary downtime. An optional side-view camera is available. Camera views are easily accessible to operators on the 7-inch LCD screen mounted in the excavator cab. Operators have the option of a split-screen to see both camera views at once.

DoosanCONNECT telematics

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, the 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 complies with Tier 4 emission standards with a modified diesel engine and after-treatment 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. It uses a diesel oxidation catalyst (DOC) to reduce particulate matter (PM) and selective catalyst reduction (SCR) after-treatment to reduce nitrogen oxides (NOx). Additionally, a variety of after-treatment systems have been implemented as part of Tier 4 compliance, such as DEF, which is used with SCR technology.


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

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
