The Doosan DX340LC-9C excavator, designed for medium-sized mines and large-scale earthmoving projects, demonstrates significant advantages in power efficiency, operating performance, durability, and operating comfort, as detailed below:
Powerful and Fuel-Efficient Engine: This model is equipped with a Doosan DL08 high-pressure common rail electronic injection engine, with a rated power of 191kW, providing stable and durable power output. It also features the EPOS intelligent control system and SPC intelligent fuel-saving mode, which intelligently senses the workload and automatically adjusts the engine speed and main pump torque to achieve a balance between performance and fuel consumption. Furthermore, its positive control system and enlarged control valve bore reduce energy loss while improving equipment response speed, further contributing to high efficiency and energy saving.
Stable Operation and Outstanding Excavation Capability: The wide track design and large track contact area, combined with a reasonable overall weight distribution, significantly improve stability during dynamic operation, reducing vibration during equipment movement and preventing tipping during slope or side lifting operations. The boom and arm have been optimized, with the boom's lower plate being a single piece of steel, and the arm thickened and reinforced with reinforcing ribs. Coupled with a reinforced bucket that conforms to the excavation trajectory, the digging force reaches 246kN, and the maximum digging depth is 7533mm, ensuring stable output even in high-load working conditions such as mining. In addition, the efficient swing motor and swing reducer work together to provide superior performance during swing operations such as slope excavation and loading.
Durable Structure and Convenient Maintenance: Key components are coated with wear-resistant and corrosion-resistant materials, and the oil filter system's filtration efficiency has been optimized, improving its adaptability to low-quality fuels and reducing the probability of malfunctions. It is also equipped with a fully automatic fuel heating function to cope with cold working conditions. Furthermore, the maintenance parts are centrally located, and the heat dissipation performance is significantly improved, making daily cleaning and maintenance easier, reducing equipment maintenance costs and downtime.
The DOOSAN DH140W-7 is a wheel excavator with remarkable performance. Manufactured by Doosan, it has an operating weight of 14350 kg and a bucket capacity of 0.6 m³. Powered by a Doosan DL06 engine with 98 kw of power, it has a rated speed of 5.5 km/h. It features high operating efficiency and is widely used in construction digging work.
