Doosan has added more power, performance, and speed to the 16-ton (14.5-t) excavator market with the T4 Interim DX140LCR-3, providing 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.
The tail swing radius on the DX140LCR-3 is only 5 ft (1.5 m), which results in a tail swing overhang of just 9 in (230 mm) over the side of the machine, making it suitable for working in congested job sites 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 DX140LCR-3 features an electronic power optimizing system that provides optimum power and fuel efficiency via four work modes, auto-idle, and machine diagnostics. Operators can work more effectively with multiple operating modes, easy-to-read display monitors, and precise control levers. 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 job sites.
A straight travel pedal is available for the DX140LCR-3. This new option streamlines the travel and transport of the machine. It is particularly suitable for the straight-forward and -backward travel common in trenching applications, as it provides a single foot pedal in the right-front corner of the cab floor that operates both tracks.
Doosan continues to focus on operator comfort with enhancements 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%, enabling operators to work longer days with less fatigue.
