Doosan’s interim Tier 4 DX140LCR-3 provides greater capabilities for site development, commercial construction, and highway/street development projects. The DX140LCR-3 excavator is a reduced tail swing machine that offers reduced machine length and added maneuverability for ease when operating in tight quarters.

The tail swing radius on the DX140LCR-3 is only 5 feet, which results in a tail swing overhang of just 9 inches over the side of the machine, making it an ideal candidate for working in congested jobsites such as streets, highways, and rail lines without blocking traffic in adjacent lanes or tracks. Reduced tail swing also minimizes the potential for machine damage when working close to buildings or walls.

The 12-foot-4-inch overall track length on the DX140LCR-3 provides stability for digging and lifting operations.

The DX140LCR-3 features an electronic power optimizing system (EPOS), which provides optimum power and fuel efficiency via four work modes, auto-idle, and machine diagnostics. The selectable work modes permit operators to get maximum efficiency and fuel economy in specific applications. A maximum speed of 2.9 mph for the excavator provides more efficient movement around jobsites.

Inside the Roll-Over Protective Structure (ROPS) cabin, both a height lever and tilting function were added to the air suspension heated seat to allow the operator to find an optimum seating position. The cabin mounting mechanism has been improved with a thickened dampening plate, and an internal coil spring has been added to reduce cabin vibration 20%.

The Doosan DX140LC-3 — like every new Doosan machine — is covered by a 48-Hour Parts Guarantee.
