DOOSAN DX530LC-5 SLR CRAWLER EXCAVATOR

Technical Description

The Doosan DX530LC-5 SLR is a heavy-duty crawler excavator engineered for demanding earthmoving and material handling applications. Powered by a robust engine delivering 373 horsepower (278 kW), this machine combines superior excavation capacity with operational efficiency through advanced hydraulic systems and intelligent power management features. The excavator weighs 117,112 pounds in operating condition, providing substantial stability and traction across challenging job sites. This model excels in deep excavation work, achieving a maximum digging depth of 49.6 feet with a maximum reach along the ground of 63.8 feet, making it ideal for large-scale mining, quarrying, and construction projects. The DX530LC-5 SLR incorporates dual variable displacement tandem axial piston pumps with cross-sensing pump technology for enhanced fuel efficiency and reduced operational costs. The swing mechanism utilizes an axial piston motor with 2-stage planetary reduction gearing, delivering maximum swing torque of 20,130 kgf/m at 8.6 rpm, enabling rapid material repositioning and efficient bucket cycles. The machine features independent track drives through high-torque axial piston motors and planetary reduction gearboxes, providing travel speeds of 3.1 to 5.4 km/h with excellent gradeability. Advanced control systems include four operating modes and four power modes with Smart Power Control (SPC) technology that reduces engine RPM during low-load demands, optimizing fuel consumption and emissions. The excavator's long undercarriage configuration, combined with its substantial bucket capacity, delivers outstanding digging forces and lift capacities suitable for high-production applications.
