Komatsu says that, with the PC20E-6, it set out to provide a machine that fulfils the requirements of a realistic working day on the construction site while being as cost-efficient as possible.
The 11.8 kW battery-powered mini excavator with 23.2 kWh battery capacity and an operating weight of 2,110 kg has a drive train developed by Komatsu in Europe.
You might not get even four hours out of the battery between charges on this – never mind a whole day – but do you really need to, especially if it saves you money? That’s the story of this machine.
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 three-and-a-half hours a day. This defined the target for the required, reliable working time with the excavator. This result makes it possible for Komatsu to offer a lower priced machine with a performance that matches the requirements of 90% of applications. Cost-efficient, see?
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).
There are various charging options, including fast charging during a 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.
Komatsu's 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.
The concept of this 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.
For those with any doubts, it also comes with the Komatsu E-Support customer programme, comprising:
- factory scheduled, free maintenance with genuine Komatsu parts
- three years or 2,000 hours warranty for the machine
- five-year or 10,000-hour parts warranty for the electric driveline components.
“The Komatsu E-Support customer program is included free of charge with every market-ready electric mini excavator and offers exclusive machine support,” said Emanuele Viel, group manager utility at Komatsu Europe.
