Komatsu PC390LC-10SLF LARGE EXCAVATORS
Product Feature
Large Digging Force
The PC390LC-10 Super Long Front is equipped with the Power Max system. This function temporarily increases digging force for 8.5 seconds of operation.
Maximum arm crowd force (ISO):
160 kN (16.3 t) → 171 kN (17.4 t) 7 % UP
(with Power Max.)
Maximum bucket digging force (ISO):
213 kN (21.7 t) → 228 kN (23.2 t) 7 % UP
(with Power Max.)
Efficient Hydraulic System
The PC390LC-10 SLF uses a Closed Center Load Sensing (CLSS) hydraulic system that improves fuel efficiency and provides quick response to the operator's demands. The PC390LC-10 SLF also introduces new echnology to enhance the engine and hydraulic pump control. This total control system matches the engine and hydraulics at the most efficient point under any load condition. There have also been improvements in the main valve and hydraulic circuit to reduce hydraulic loss, resulting in higher efficiency and lower fuel consumption.
Two Boom Mode Settings
Smooth boom mode provides easy operation for gathering blasted rock or when scraping down. Power boom mode maximizes digging force for more effective excavating.
Large Undercarriage Design
The PC390LC-10 SLF uses a large undercarriage design that increases overside lift capacity by up to 20% and improves lateral stability, especially for applications that require long arms or heavy attachments.
Large Maximum Drawbar Pull
Large maximum drawbar pull provides excellent steering and slope climbing performance (13.3% up over the PC390LC-10 SLF)
Maximum Drawbar Pull 329 kN 33510 kgf 73,880 lb
Working Mode Selection
The PC390LC-10 SLF excavator is equipped with six working modes (P, E, L, B, ATT/P and ATT/E). Each mode is designed to match engine speed, pump flow, and system pressure to the application. The PC390LC-10 SLF features a new mode (ATT/E) which allows operators to run attachments while in Economy mode.
Eco-Gauge Assists with Energy Saving Operations
The Eco-gauge and new fuel consumption gauge are viewed on the right side of the color monitor and assist the operator in maintaining low fuel consumption and environment friendly operation.
Newly Designed Wide Spacious Cab
The newly designed wide spacious cab features a high back, fully adjustable seat with a reclining backrest. The console and seat have an integrated design so that they move together and provide additional comfort for the operator. The new higher capacity operator seat has been enhanced to provide more comfort.
Low Vibration with Viscous Cab Mounts
The PC390LC-10 SLF uses viscous mounts for the cab that incorporate a longer stroke and the addition of a spring. The cab damper mounting combined with a high rigidity deck reduces vibration at the operator’s seat.
Large High Resolution LCD Monitor Panel
A new large, user-friendly, high resolution LCD color monitor enables accurate and smooth work. Screen visibility and resolution are further improved compared to the previous LCD monitor panel. The switches and function keys are easy to operate and provide simple navigation through the monitor screens.
Data is displayed in 25 languages to support operators around the world.
Operational "ECO" Guidance
The monitor panel provides operational advice to the operator to help improve machine efficiency and lower fuel consumption. The operator can access the ECO guidance menu to check the Operation Records, Eco Guidance Records, and Average Fuel Consumption Logs.
Improved Attachment Control
The PC390LC-10 Super Long Front is capable of storing up to ten different attachments in the new monitor panel. The name of each attachment can be changed for better tool management. Hydraulic flow rates can be easily adjusted for one-way and two-way flow attachments.
KDPF Regeneration Notification
The LCD color monitor panel provides the operator with the status of the KDPF regeneration, without interfering with daily operation. When the machine initiates active regeneration an icon will appear to notify the operator.
Abnormalities Display with Code
When an abnormality occurs an error code is displayed on the monitor. When an important code is displayed, a caution lamp blinks and warning buzzer sounds to alert the operator to take action. The monitor also stores a record of abnormalities for more effective troubleshooting.
Advanced Monitoring System
The monitor provides advanced monitoring diagnostics to assist with troubleshooting and reduce costly downtime.
Maintenance Tracking
When the machine approaches or exceeds the oil and filter replacement interval, the monitor panel will display lights to inform the operator.
Rear-view Monitoring System (standard)
On the large LCD color monitor the operator can view the image from one camera that will display areas directly behind the machine. An optional 2-camera system is available.
