Get power and efficiency where it counts with the only excavator in its class with a fully electric swing system. This innovation increases swing speeds while converting wasted energy into a 70-horsepower boost for work-equipment performance and lower fuel consumption. When swinging, all available hydraulic power is sent to the boom, arm and bucket to help improve cycle time and increase productivity.
- Electric swing system yields up to a 15 percent increase in productivity and up to a 20 percent reduction in fuel consumption — a rare dual gain in power output and efficiency*
- Tool control system for efficient, fast changes and versatile attachment operation
- Redesigned cab features a heated, air-suspension seat, ergonomic joysticks and a standard** KomVision 360° camera system
*Compared to the conventional PC360LC-11
**To be introduced as a running change after model release

Features and benefits
High-performance swing
Superb swing power and speed with an ultracapacitor that captures energy, then charges and discharges rapidly to power the electric swing motor.
High-response engine
Great engine response, performance and efficiency with an engine-mounted motor/generator powered by the ultracapacitor, which provides up to a 70 hp boost to the engine.
Operate more effectively
Help control costs while driving productivity by combining Komatsu’s PC365LC-11 electric swing motor and the Tier 4 engine to reach up to 20% in fuel savings compared to a non-hybrid excavator model in the same size class.
Complete jobs quicker
Get fast cycle times and boost productivity with a powerful electric swing motor and a closed-center load sensing system (CLSS). The CLSS delivers hydraulic power to the excavator for an immediate high performance, smooth and precise operation.
Enhanced operator experience
Your operators will love the updated working environment. The cab includes a new premium, heated, air-suspension seat, ergonomic joysticks to help reduce operator fatigue and access to a KomVision 360-degree camera system.
Improved stability
The PC365LC-11 excavator features a 6% increase in operating weight* designed to help its stability so operators can dig, lift and handle heavy materials confidently and effectively, especially when working on uneven or challenging terrain. *Compared to a traditional Komatsu 36-ton diesel engine excavator.
Efficient attachment operation
The tool control system improves efficiency, precision and performance by enabling quick switching between attachments — with accurate, preconfigured hydraulic settings tailored to each tool.
Add Smart Construction 3D Guidance
An optional Smart Construction 3D Machine Guidance kit can be factory-installed to provide access to 3D design and topographic data, helping drive work accuracy, control load volumes and promote optimized operations.
Transferable warranty
All electric swing system components come with an extended warranty for added peace of mind. These vital components on your PC365LC-11 are covered by a 7-year/15,000-hour fully transferable warranty.
