A Sustainable Revolution: Komatsu Unveils Battery-Powered 20-Ton Excavators

A Sustainable Revolution: Komatsu Unveils Battery-Powered 20-Ton Excavators

In an era where sustainability and environmental consciousness are at the forefront of technological innovations, the construction industry is no exception to the shift towards cleaner and greener practices. Komatsu, a global leader in construction equipment, has introduced two revolutionary electric excavators, the PC 200LCE-11 and 210LCE-11, both belonging to the 20-tonnes class. Powered by cutting-edge lithium-ion batteries developed in collaboration with Proterra, a renowned US manufacturer of lithium-ion batteries, these new models signify a leap towards a more sustainable and efficient future in the construction sector.

From Minis to Titans: Komatsu's Electric Excavator Lineup

This latest announcement from Komatsu follows closely on the heels of the introduction of the PC33E-6 electric mini-excavator, which marks a significant milestone in the transition to cleaner construction equipment. The unveiling of the 20-ton electric excavators represents a logical progression, broadening the spectrum of electric machinery offered by Komatsu.

A Glance at the Battery System

At the heart of these electric excavators lies the Proterra Powered lithium-ion battery system. With an impressive onboard energy storage capacity of 451 kWh, it offers up to approximately 8 hours of uninterrupted operating time on a full charge, depending on working conditions. While the battery is robust in terms of performance, it is also designed to be user-friendly. It takes just about nine hours to achieve a full charge using the included charger.

The Environmental Impact: Zero Emissions

The most significant advantage of these electric excavators is their eco-friendliness. By eliminating the need for traditional internal combustion engines, they produce zero emissions on the job site. This eco-friendly feature is a game-changer for environmentally-conscious construction companies and government initiatives focused on reducing carbon footprints.

The Quest for Efficiency

The introduction of the PC 200LCE-11 and 210LCE-11 electric excavators is not only about sustainability but also efficiency. Electric equipment often boasts quieter operation, reduced maintenance costs, and potentially lower operating expenses. These factors translate into increased productivity and cost savings in the long run.

A Global Shift Towards Sustainable Construction

Komatsu's foray into battery-powered excavators aligns with the broader global shift towards sustainable construction practices. It signifies a future where cleaner, more efficient construction equipment is the norm, reducing the industry's environmental impact.


Komatsu's introduction of the PC 200LCE-11 and 210LCE-11 battery-powered 20-ton excavators is a defining moment in the construction industry's journey towards sustainability. These machines not only exemplify the potential of electric technology in construction but also signify a paradigm shift towards eco-friendly, efficient practices. As these electric excavators become more accessible, they promise to transform the construction sector, offering a glimpse of a cleaner and more sustainable future. Komatsu's commitment to innovation and environmental responsibility is setting a powerful example for the industry, and the transition to cleaner construction equipment is now more exciting than ever.
