2024 Komatsu Excavators PC490LC-11
High production, easily transportableBuilt for high production jobs, the PC490LC-11 is a large but portable excavator with a heavy-duty reinforced undercarriage for high lift capacity, lateral stability and added durability.
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.
- Smooth operation, quick cycle times, great multi-function, while lowering fuel consumption from closed-center load-sensing hydraulic system.
- 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.
- 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.
- Engine oil check and filter locations integrated into one side to allow easier maintenance access.
- 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.
