2024 Komatsu Excavators PC290LC-11
High production earthmoving from an excavator designed to be easily transportable.The PC290LC-11 is a mid-size hydraulic excavator designed for long reach arm and boom combined with a heavy-duty undercarriage provide extended reach with a stable platform.
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.
- Updated, large, high-resolution LCD color monitor to ease accurate and smooth work. Key machine information displayed in user-friendly interface, rearview camera and DEF level gauge display added to default main screen.
