Product Description
The used Doosan 140 is a versatile 14-ton mid-size excavator, engineered to deliver consistent performance across construction, landscaping, and utility projects. Combining compact agility with robust power, this machine has become a go-to choice for contractors seeking a balance of efficiency and capability, making it ideal for both small-scale jobs and larger site operations.
Advantages
A standout advantage of the Doosan 140 is its exceptional maneuverability. With an operating weight of approximately 14,000 kg, it navigates tight spaces—such as residential yards or urban construction sites—with ease, while maintaining enough stability for heavy lifting and digging. Powered by a Doosan DL06 diesel engine generating around 93 kW (125 HP) at 2,000 rpm, it offers ample power to tackle compacted soil, trenching, and material handling without sacrificing fuel efficiency.
Fuel economy is a key strength, thanks to the engine’s advanced injection system, which optimizes fuel burn and reduces emissions. This not only lowers operational costs but also aligns with modern environmental standards, making it a sustainable choice for long-term use.
Durability is built into its design, with a reinforced boom and arm, high-strength steel components, and a rugged undercarriage that resists wear from daily use. The hydraulic system, operating at 31.9 MPa, ensures smooth, responsive movements, minimizing stress on parts and reducing maintenance needs—critical for maximizing uptime on busy job sites.
Features
The Doosan 140 is packed with features that enhance productivity. Its maximum digging depth of approximately 5,500 mm and reach of 8,500 mm at ground level allow it to handle deep trenches and long-reach tasks, while the 5,200 mm maximum dump height ensures efficient loading into trucks. The bucket capacity, ranging from 0.6 to 1.0 cubic meters, adapts to various materials, from loose soil to gravel.
The undercarriage, with a 3,600 mm track length, 2,100 mm track gauge, and 500 mm track width, provides stable traction on uneven terrain, with a ground pressure of around 45 kPa—gentle enough for soft surfaces like lawns or paved areas.
Operator comfort is prioritized in the cab, which includes air conditioning, an adjustable suspension seat, and intuitive controls. A 7-inch LCD monitor displays real-time data on fuel usage, engine performance, and maintenance alerts, keeping operators informed. The ROPS/FOPS-certified structure ensures safety, while large windows and mirrors enhance visibility for precise operation.
Additional features include a 250-liter fuel tank for extended work sessions, a 110-liter hydraulic oil capacity, and a swing speed of 11.5 rpm for quick positioning. Travel speeds of 3.0 km/h (low) and 5.0 km/h (high) enable efficient movement across job sites.
