2021 Caterpillar 390FLME
Product Description
Engineered for large-scale excavation, this 2021 Caterpillar 390FLME delivers exceptional performance through advanced hydraulic architecture and proven powertrain technology. Operating at 90 tons with a 92,020 kg working weight, the machine centers on a Cat C18 ACERT engine producing 391 kW of rated power from an 18.1-liter displacement. Hydraulic efficiency reaches professional-grade standards with main pump flow of 952 L/min in equipment mode and 1,064 L/min while traveling, supported by 35 MPa circuit pressure across all major systems.
- Power System: Cat C18 ACERT engine, 391 kW at optimal RPM, 590 Nm turning torque
- Hydraulic Capacity: 813L tank, 997L total system volume, 35 MPa working pressure
- Cylinder Configuration: 220×2262 mm arm cylinders, 210×1967 mm boom cylinders, reinforced 200×1451 mm bucket cylinders
- Rotation Performance: 6.2 RPM swing speed with dedicated 35 MPa rotary circuit
- Fuel Autonomy: 1,240L tank capacity for extended operational cycles
Currently located in Xuzhou, Jiangsu, this joint venture-manufactured excavator represents Caterpillar's commitment to engineeri
