DOOSAN DX300LC-3 SLR CRAWLER EXCAVATOR

Technical Description

The Doosan DX300LC-3 SLR is a robust long-reach hydraulic excavator designed for heavy-duty digging and extended reach applications. Equipped with a powerful Doosan DL06 engine delivering a net power output of 213 hp (159 kW) at 1800 rpm, it offers efficient torque for demanding tasks. The machine features a super long reach (SLR) boom measuring 10 meters and a 7-meter stick, paired with a 0.64 m³ bucket, optimizing it for precise excavation deep and far from the base. It achieves a maximum digging depth of 45.3 feet and a maximum reach along the ground of 57 feet, providing superior reach capabilities beyond standard models. The DX300LC-3 SLR maintains an operating weight of approximately 68,167 lbs, balancing stability with mobility on varying ground conditions. The excavator operates on a tracked undercarriage with 600 mm wide shoes for enhanced traction and lower ground pressure. Its hydraulic system is engineered to deliver high system pressures (up to around 350 bar) for powerful boom, arm, and bucket operations, ensuring efficient digging force and smooth hydraulic response. The machine’s swing mechanism provides a strong swing torque, critical for rotating the long boom and arm during extended reach operations. Additional operating specifications include travel speeds suitable for both job site mobility and transport. The overall design supports durability with bolt-on cutting edges and reinforced boom and arm structures for long-term performance under intense operational conditions. The DX300LC-3 SLR’s blend of power, reach, and advanced hydraulics makes it ideal for specialized tasks such as dredging, riverbank works, and large excavation projects requiring extended reach and precision.
