Komatsu expands electric product range with new PC20E-6 mini excavator
Vilvoorde, August 2025 — Komatsu is pleased to announce the commercial availability of their latest addition to their electric product range, PC20E-6. Designed to meet the demands of a full working day, the Komatsu PC20E-6 is ideal for both traditional jobsites and noise-sensitive or indoor applications where zero emissions are required.
The aim of the design is to provide a machine that fulfils the requirements of a realistic working day on the construction site while being as cost-efficient as possible.
Absolute peace of mind with Komatsu E-support
The 11.8 kW battery-powered mini excavator with 23.2 kWh battery capacity and an operating weight of 2110 kg has a drive train specially developed by Komatsu in Europe. This not only means a major advantage through comprehensive quality control options, but also offers a special guarantee on the Komatsu electric components. This machine also comes with Komatsu “E-Support” customer program. Specially developed for owners of Komatsu electric mini excavators, this program consists of three parts:
- Factory scheduled, free maintenance by a Komatsu-trained technician using genuine Komatsu parts;
- 3 years or 2,000 hours warranty for the machine;
- 5-year or 10,000-hour parts warranty for the high-quality components of the electric driveline.
“The Komatsu E-Support customer program is included free of charge with every market-ready electric mini excavator and offers exclusive machine support,” adds Emanuele Viel, Group Manager Utility at Komatsu Europe.
The bottom line is that the risk for the end customer is significantly reduced, especially when it comes to exploring the electrification advances in the industry.
Data-driven development for reliable performance
Numerous data-driven findings from Komatsu have been incorporated into the development of the machine.
The Komatsu fleet management system Komtrax was used to analyse 40,000 working days of mini-excavators of a comparable size. The result: 90% of mini excavators work less than 3.5 hours per day. This defined the target for the required, reliable working time with the excavator. This result makes it possible for Komatsu to offer an attractively priced machine with a performance that exactly matches the requirements.
Depending on the operating mode, the PC20E-6 offers capacity for around 3:20 hours (operating mode P), 3:40 hours (operating mode E0) or 4:00 hours (operating mode E1).
Thanks to various charging solutions suitable for different contexts, the machine can also be recharged flexibly, for example by fast charging during the lunch break. The PC20E-6 already operates in the high-voltage range with a system voltage of 77V. An on-board charging option for 230V and 3kW charging power compatible with various plug adapters is offered as standard, as well as the option of an external DC quick charger for 400V and 12kW charging power (from October 2025).
Komatsu's extensive data analysis, including findings from its electric forklift trucks in Japan, suggests a battery service life of around 10 years, assuming it is charged and discharged daily during operation.
Efficient and sustainable operation
The machine is also attractive because of its simplified daily maintenance. Compared to the conventional PC20 with combustion engine, some aspects of daily maintenance prior to commissioning are no longer necessary. There is no need to check:
- the dust indicator
- the water separator
- drain water and sediment from fuel tank coolant level,
- add coolant oil level in engine oil pan, add oil
The concept of this innovative machine also includes operation with ID keys as standard. Each machine is supplied with a registration key and three operator keys. One machine can register up to 255 operator keys, while an operator key can be stored for an unlimited number of machines across all models. This is another way to save resources and make every day work more efficient!
Moreover, the PC20E-6 contributes to a company's ecological footprint with a recycling rate of 99% of its total mass. This makes it an ideal solution for tenders that require no local emissions or are aimed at operations inside buildings or in noise-sensitive areas
