Komatsu introduced the PC365LC-11 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, according to Komatsu.
The PC365LC-11 features an 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 and delivering up to a 15 percent increase in productivity compared to Komatsu’s PC360LC-11 and PC360LCi-11, the company says. An ultracapacitor stores an additional 70 electric horsepower for acceleration when the engine is in ultra-low idle for on-demand power.
The ultra-low idle state reduces fuel consumption by up to 20 percent, Komatsu says, 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 is required. 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. The company adds that these features also make the PC365LC-11 significantly quieter.
Compared to the previous model, the PC365LC-11 includes new features and enhancements across three key areas: operator experience, technology and attachment flexibility.
A new heated air-suspension operator seat features a high leather back, improved cushioning and multiple adjustments for greater operator comfort, Komatsu says. New proportional joysticks offer an intuitive, ergonomic feel, reducing operator fatigue and wrist stress.
Featuring the KomVision camera system standard, operators can get a real-time, bird’s-eye view of the machine and its surroundings. An optional Smart Construction 3D machine guidance kit can be factory-installed and provides operators in the field and managers in the office access to 3D design and topography data that helps drive work accuracy, control load volumes and promote optimized operations.
A tool control system is standard for machine configurations with an additional hydraulic piping line, which allows operators to configure and store flow rates and target pressures for multiple attachments, according to the company. This information is then displayed on the in-cab monitor interface. Komatsu says this system improves efficiency, precision and performance by enabling quick switching between attachments with accurate, preconfigured hydraulic settings tailored to each tool. Optional hydraulic quick-coupler piping can be factory-installed for easy tool attachment.
“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 at Komatsu. “To highlight these performance enhancements, we’re emphasizing the concept of ‘multifunction plus’ as the defining feature of this machine.”
