2023 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 high-strength steel castings on the boom, arm and bucket link
- Closed-center load-sensing hydraulics for precise, fine control
- Large displacement high-efficiency pumps provide optimal attachment flow
- Large, spacious, quiet cab featuring standard air suspension seat
- 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.
- A ROPS cab that conforms to ISO 12117-2 comes as standard equipment. It also satisfies requirements for level 1 operator protective guard (OPG) and top guard (ISO 10262).
- An operator identification ID can be set up for each operator and used to manage operation information of individual machines using Komtrax data. Data can analyze operation status by operator and by machine.
- Auto idle shutdown automatically shuts the engine down after idling for a set period to reduce unnecessary fuel consumption and exhaust emissions. Time before engine is shutdown can be programmed from 5 to 60 minutes.
