Doosan’s 14-metric-ton DX140LC-5 and DX140LCR-5 Tier 4-compliant crawler excavators are designed for long life with an extra-sturdy frame and reinforced superstructure. They come standard with permanently sealed and lubricated track links, and the bushings and hard-wear disks are designed for reliability as well as extended service intervals.

The DX140LCR-5 model offers a shorter tail swing, allowing operators greater flexibility where space is a premium.

Both excavators come standard with an improved 7-inch liquid-crystal display (LCD) screen that allows operators to continue monitoring the excavator parameters while viewing the rearview or optional side-view camera image. Critical machine data appears next to the camera view.

Doosan added auto shutdown to both models to help owners save fuel during non-working conditions. Operators can configure the idle time from 3 to 60 minutes. When enabled, the feature will shut down the excavator’s engine when the preset idle time is met. This is particularly helpful in California where state regulations require idling for only 5 minutes for off-highway machines.

In addition to SPC, auto shutdown and LCD screen updates, the new Doosan DX140LC-5 and DX140LCR-5 crawler excavators have the following updates:

  • Improved anti-skid plates: for easier engine access for machine maintenance
  • Emergency engine stop: relocated for easier operator access
  • Improved serviceability: allows for easier access to components and less time for maintenance
  • Upgraded alternator: delivers improved power for electrical components
  • New front window design: provides good visibility to the work area

A new selectable feature, Smart Power Control (SPC), is available on both models and consists of two systems — Variable Speed Control and Pump Torque Control — that work together to improve machine efficiency while maintaining productivity and reducing fuel consumption.

The crawler excavators comply with Tier 4 emission standards with modified diesel engines 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. It utilizes a diesel oxidation catalyst (DOC) to reduce particulate matter (PM) and selective catalyst reduction (SCR) aftertreatment to reduce nitrogen oxides (NOx). Additionally, a variety of aftertreatment systems have been implemented as part of the Tier 4 compliance, such as DEF, which is used with SCR technology.
