Technical Description
The Caterpillar 390F L hydraulic excavator is engineered for high productivity and efficiency in heavy-duty applications such as quarrying, road construction, and large-scale earthmoving. It is powered by a robust Cat C18 ACERT engine delivering 524 hp (391 kW) net power at 1,700 rpm, with a displacement of 18.1 liters (1104.5 in³), a bore of 5.7 in (145 mm), and a stroke of 7.2 in (183 mm). The engine meets stringent EU Stage IV emission standards without power derating below 2300 m altitude, ensuring compliance and environmental responsibility. It boasts a maximum drawbar pull of 132,637 lbs (590 kN) and a top travel speed of 2.8 mph (4.5 km/h).
The excavator features a powerful hydraulic system with a main implement pump flow capacity totaling 266 gallons per minute (952 L/min) and a travel pump flow of 281 gal/min (1064 L/min), operating at pressures up to 5076 psi (35,000 kPa) for equipment and travel functions, and 3770 psi (26,000 kPa) for swing system operations. Its boom and stick cylinders have bores of 8.3 in (210 mm) and 8.7 in (220 mm), with stroke lengths of 77 in and 89 in, respectively. The machine’s operating weight is approximately 190,204 lbs (86,275 kg) with a fuel capacity of 328 gallons (1242 L) and hydraulic system capacity of 263 gallons (996 L), enabling long operational shifts.
Dimensionally, the 390F L stands 12.6 ft tall at the cab, has a ground clearance of 3 ft, a track length on ground of 20.9 ft, a width of 9.1 ft across tracks, and a tail swing radius of 15.5 ft. The undercarriage consists of 51 shoes per side, 9 track rollers, and 3 carrier rollers designed for stability and durability. Its advanced hydraulic system includes an ACS valve for enhanced responsiveness and fuel savings, while the cab provides an ergonomic, quieter operator environment enhanced by Cat Connect technology for cost and production optimization.
