Komatsu introduces the new PC365LC-11 multifunction plus excavator to the North American market.

It features a refreshed exterior design, an enhanced operator cab, and several new standard and optional features built and optimized for the North American construction market.

The PC365LC-11 is the only excavator in its class featuring an innovative electric swing system with “boom-up” power assist. The dedicated electric swing motor improves swing speeds and operational efficiency, reducing cycle times in multifunction applications delivering up to a 15% increase in productivity.* The ultracapacitor stores an additional 70 electric horsepower for acceleration when the engine is in ultra-low idle for instantaneous power to the work equipment on demand.

Komatsu's new PC365LC-11 excavator is built to excel in multifunction applications by enhancing productivity, fuel efficiency and operator comfort.

The ultra-low idle state reduces fuel consumption by up to 20%, extending runtimes and lowering total cost of ownership. All electrical energy used in this system is generated during normal operation and stored in the ultracapacitor — no external charging needed. Without the need for hydraulic power for swing operations, this power is fully available for the boom, arm and bucket cylinders. Optimizing hydraulic flow further reduces digging cycle times and reduces work equipment lag, enabling smoother operation in multifunction applications. These features also make the PC365LC-11 significantly quieter.

Warranty

For added peace of mind, this machine’s electric powertrain components are covered by a 7-year/15,000-hour transferable warranty.
“The PC365LC-11 was engineered for excellence in multifunction applications by leveraging its innovative electric powertrain system to boost jobsite productivity while reducing fuel consumption,” says Matthew Moen, Product Manager.
“To highlight these performance enhancements, we’re emphasizing the concept of ‘multifunction plus’ as the defining feature of this machine.”
