Used Doosan DH300LC-7 Excavator

The Doosan DH300LC-7 excavator offers the following advantages:

Powerful: Equipped with a Doosan DE08TIS or DB08TIS engine rated at 147kW/1900rpm, this high-powered engine and advanced hydraulic system deliver powerful digging force during operation. Bucket digging forces reach 188-199.9kN, and arm digging forces range from 155.8-164.6kN, enabling the excavator to meet the demands of diverse and complex working conditions.

Excellent Operability: Equipped with advanced control valves and joysticks, the excavator delivers fast, smooth, and responsive control. During travel operations, the advanced hydraulic circuit optimally distributes oil flow between travel and boom, ensuring more precise and safe operation. During complex operations, flow distribution between the boom, arm, and bucket is more optimized, ensuring operational stability. Furthermore, the swing torque has been increased by 14%, and a standard swing check valve allows the operator to precisely control the upper swing angle during acceleration and deceleration, significantly improving operating efficiency. Excellent Fuel Economy: Equipped with an air-to-air intercooled engine and a new, improved electronic EPOS system, it reduces fuel consumption while ensuring excellent operating performance, resulting in excellent energy efficiency.
High Stability: Featuring a reinforced chassis with an increased counterweight of over 400 kg, the machine’s center of gravity is lowered and optimized, significantly improving dynamic stability and side digging capability, enabling stable operation even in challenging working conditions.
Comfortable Operation: The cab meets international standards, offering spacious space and excellent visibility. Its low-noise, low-vibration design and comfortable seat provide the operator with a safe, comfortable, and ergonomic driving environment. Furthermore, a series of user-friendly features, such as a folding cup holder, long wiper blades, and a front window defrost system, further enhance the operator experience.
Easy Maintenance: The electrical control connection box features a pull-out drawer design for easy maintenance and repair. Quick-connect oil hoses enable rapid oil draining, prevent leaks, and reduce pollution. Furthermore, key components are constructed of high-strength steel, resulting in a durable and robust structure that reduces the risk of failure and lowers maintenance costs. High Reliability: Doosan maintains a world-class reliability testing center to ensure its products meet or exceed market standards. The boom ends and center utilize an integrated casting process to prevent cracking and have passed stress analysis and durability testing. The connections between the main frame, boom, and counterweight are reinforced to increase rigidity, enabling the main frame to better support extended booms and heavy-duty attachments, ensuring operational safety.
