For reduced machine length and added maneuverability, choose the DX140LCR. It has a reduced short tail swing profile to work in confined areas without sacrificing performance. The DX140LCR-3 is ideal for roadways, railroad rights of way, bridge areas and urban jobsites.

The DX140LCR-3 shares the performance strengths of the entire Doosan excavator lineup. Increased torque provides efficient digging power and movements. The high pressure common rail fuel system on the engine teams with the EPOS (Electronic Power Optimizing System) for optimum power and fuel efficiency. The EPOS also provides multiple working modes, automatic deceleration and machine diagnostics. Work more effectively with multiple operating modes, helpful control panels and the easy to use and precise control lever.

The world-class cabin combines superior comfort, excellent visibility, low noise levels and a roomy environment. The reclining, height- and weight adjustable standard suspension seat has a headrest and adjustable armrest. Work naturally with the easy to use, intuitive controls. The high-performance air conditioning offers adjustable air flow, electronic controls and five operating modes. Store your belongings in the storage bins.

Designed for long life with an extra-sturdy frame and reinforced superstructure, the DX140LCR is built for reliability. Bushings and ultra hard wear disks are designed for extended service intervals and steady performance. The permanently sealed and lubricated track links maximize uptime and reduce operating costs

Reduce your operating costs with longer service intervals and easy access to key daily checkpoints. Get easy access to radiators and other key components. Rely on excellent filter design, efficient air cleaner and centralized grease points.
