2024 Komatsu Excavators PC390LC-11

High production earthmoving from an excavator designed to be easily transportable.

The large undercarriage design of the PC390LC-11 large hydraulic excavator increases over-side lift capacity and stability in applications that require long arms or heavy attachments. It’s ideally sized for high production earthmoving applications while being easily transportable.

Features may include:

Large displacement high efficiency pump
  • Large displacement hydraulic implement pumps provide high flow output at lower engine RPM, operation at the most efficient engine speed.
Closed-center load-sensing hydraulic system
  • Smooth operation, quick cycle times, great multi-function, while lowering fuel consumption from closed-center load-sensing hydraulic system.
Built for strength
  • Equipment designed for long-term durability with high resistance to bending and torsional stress. Booms and arms are constructed with thick plates of high tensile strength streel and designed with large cross-sectional areas.
Cleaner emissions
  • A heavy-duty aftertreatment system that combines a Komatsu Diesel Particulate Filter (KDPF) and selective catalytic reduction (SCR). The system injects the correct amount of diesel exhaust fluid at the proper rate, decomposing nitrogen oxide.
Easy access
  • Engine oil check and filter locations integrated into one side to allow easier maintenance access.
Advanced ergonomic design
  • Wide spacious cab includes a heated air suspension seat with reclining backrest. Seat height and position are easily adjusted using a pull-up lever. Armrest position easily adjusted with the console.
