Easier to Transport
Make equipment transportation easier with the Doosan® DX170LC-5. Ideal for light excavation – such as in landscaping and residential basement digging – this reliable performer doesn’t need a special transport permit because of its narrow width and reduced weight: The combined weight of the crawler excavator, its trailer and the class-7 tow vehicle can easily fall under the 80,000-pound GVWR limit.

Exceptional Power and Control
The DX170LC-5 delivers outstanding performance with the high-pressure common rail fuel system on the engine and Electronic Power Optimizing System (EPOS). Choose between four work modes, auto-idle and machine diagnostics. Smart Power Control (SPC) improves 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 only is active in the digging work mode. Auto shutdown helps owners save fuel while the machine isn't working. The EPOS links to the engine's Electronic Control Unit, electronically synchronizing the engine and hydraulic system. The system enables power and work operating modes, electronic control of fuel consumption, auto-idle, hydraulic oil flow regulation and control, and machine diagnostics. It also improves control, allowing you to precisely place material and easily level ground.

Comfort and Convenience
Like all Doosan excavators, the DX170LC-5 is known for operator comfort. Advantages include a roomy cab, simple controls, excellent visibility, high-performance air conditioning and extra storage. The standard air suspension seat includes height and weight adjustments, headrest and armrest, and reclining options. If equipped with the optional two-way auxiliary hydraulics, use the optional foot pedal or joystick buttons to control hydraulic attachments.

The standard 7-inch color LCD monitor shows machine information, including operation history, flow rate control and filter/oil information. It also displays video from the rearview camera, which is uniquely placed to give you better visibility in blind spots. A split-screen mode enables you to see critical machine information and the camera simultaneously.

Designed for Durability
Durable materials and extensive testing ensure long-term reliability. The D-type frame and chassis adds strength and minimizes distortion, while the arm assembly is reinforced for longer life. The bucket pivot pin features a polymer shim to reduce wear and increase grease retention.

Reduced, Simplified Maintenance
Longer maintenance intervals — and easy maintenance — minimize your time in the shop. Key maintenance areas are easy to access, and grease points are centralized for easy maintenance.

Enjoy reduced maintenance costs and extended machine life with the durable x-chassis, strengthened boom and arm assembly, and extended greasing intervals. Easily access the oil filter, air cleaner, fuel filter, radiators and other engine components. The centralized boom and arm grease points are grouped for easy maintenance. The DX170LC-5 also comes with a standard three-year subscription to DoosanCONNECT®, which lets you remotely monitor and manage maintenance to reduce operating costs.

Tier 4 Technology
To comply with Tier 4 emissions standards, the DX170LC-5 incorporates a high-pressure common-rail (HPCR) fuel delivery system as well as cooled exhaust gas recirculation (CEGR) combined with a diesel oxidation catalyst (DOC) and selective catalyst reduction (SCR).
