Technical Description

The Doosan DX140LCR-3 is a compact crawler excavator designed for versatile construction and earthmoving applications. Powered by a Cummins QSB 4.5 engine, this machine delivers 109 horsepower at 2,200 rpm, providing efficient power for consistent work cycles while maintaining fuel economy. The excavator features a robust hydraulic system with a main pump capacity of 2x114 l/min at 1,850 rpm, enabling precise control and reduced cycle times for digging and material handling tasks. With an operating weight of 33,510 lbs and a track width of 600 mm, the DX140LCR-3 offers excellent stability and maneuverability on job sites while maintaining a compact footprint suitable for confined spaces. The machine boasts impressive reach capabilities with a maximum digging depth of 19.7 feet and a digging reach of 28 feet, making it effective for foundation work, trenching, and general excavation. The spacious cab provides operator comfort during extended shifts, featuring intuitive controls and excellent visibility. Transport dimensions are 7.19 meters in length, 2.59 meters in width, and 3.09 meters in height, facilitating easy relocation between job sites. The hydraulic system is complemented by a high-capacity gear pump that improves pilot line efficiency, enhancing overall operational performance. While the DX140LCR-3 excels in standard excavation work with its strong hydraulic precision, it may be better suited for light to medium-duty applications rather than extremely heavy-duty tasks requiring maximum power. This model represents an ideal balance between capability, portability, and operational efficiency for contractors seeking a reliable mid-sized excavator.
