Product Description
Engineered with a DC13 powerplant delivering 257 kW at 1800 rpm, this 2022 Doosan DX520LC-9C excavator represents joint venture manufacturing at its finest. Twin variable axial piston pumps supply 2×355 L/min hydraulic flow, operating at 33 MPa working pressure to generate exceptional bucket digging force of 282.2 kN and stick force reaching 247.0 kN. Weighing 50,800 kg with bucket capacity ranging from 2.72 to 3.2 m³, this 52-ton machine combines raw power with precision control.
Hydraulic architecture includes dedicated circuits for travel (33 MPa), swing (30 MPa), and pilot control (35 MPa), ensuring responsive operation across all functions. The rotating platform achieves 8.3 rpm with 16,304 Nm torque, while maximum digging reach extends to 10,765 mm with 6,765 mm depth capability. Transport dimensions of 11,530×3,340×4,125 mm facilitate efficient logistics.
Located in Wenzhou, Zhejiang, this unit features 600 mm track plates across 5,455 mm track length, supported by triple-roller undercarriage configuration. Fluid capacities include 626L fuel, 390L hydraulic reservoir, ensuring extended operational intervals between service.
