Technical Description
The Komatsu PC390LC-10 SLF is a large hydraulic excavator engineered for high productivity and stability in demanding earthmoving applications. Designed with a super long front (SLF) configuration, this model delivers exceptional reach and digging depth, making it ideal for large-scale excavation, dredging, and slope work. The machine is powered by a Komatsu SAA6D107E-1 engine, producing a net output of 257 horsepower (192 kW) at 1,950 rpm, meeting EPA Tier 4 Interim and EU Stage 3B emissions standards. Its advanced electronic control system optimizes air flow, EGR gas flow, fuel injection, and aftertreatment functions, ensuring efficient operation and enhanced diagnostic capabilities. The PC390LC-10 SLF features a closed-center load-sensing (CLSS) hydraulic system that improves fuel efficiency and provides rapid response to operator inputs. With six selectable working modes—P, E, L, B, ATT/P, and ATT/E—the excavator adapts to various job requirements, balancing power and economy. The machine’s operating weight reaches up to 91,540 lbs, providing excellent stability and lifting capacity. Maximum digging depth is 40.3 feet, and maximum reach along the ground extends to 59.5 feet, enabling efficient work in deep or wide trenches. The excavator is equipped with a Komatsu Diesel Particulate Filter (KDPF) and a variable geometry turbocharger for improved emissions control and engine performance. Additional features include a spacious ROPS cab with operator comfort enhancements, easy maintenance access points, and Komtrax telematics for remote monitoring and management. The PC390LC-10 SLF is built for durability, featuring high-strength steel components and a robust undercarriage, making it a reliable choice for heavy-duty construction and mining environments.
