Komatsu to exhibit 20-ton Proterra Electric Hydraulic Excavator at bauma

Komatsu will exhibit a 20-ton class electric hydraulic excavator equipped with a lithium-ion battery system for the first time at bauma 2022, a leading international trade fair for construction equipment to be held in Munich, Germany, from October 24 through 30.

The machine is powered by a lithium-ion battery system from U.S.-based Proterra. Since January 2021, the two companies have been jointly developing electric medium-sized hydraulic excavators and have been conducting PoC (Proof of Concept) tests on advance research machines at customers’ construction sites. The machine is scheduled to be introduced to the Japanese and European markets in FY2023.

Hydraulic excavators are the most versatile type of construction equipment, and the mid-size class, in particular, is used in a wide range of jobsites and applications, mainly in earth excavation and
loading operations, requiring power and durability to withstand heavy-load work. This model optimizes the entire body control system by capitalizing on Komatsu’s proprietary coordinating technology.

It specifically integrates Proterra’s lithium-ion battery technology which has a proven track record for use in heavy-duty and commercial vehicles deployed in various fields around the
world, with Komatsu’s components, such as the hydraulic pump, controller, and electric motor for work equipment operation.

In addition, Komatsu has developed a robust cage structure to provide additional protection onboard the vehicle for its battery packs. As a result, Komatsu has achieved digging performance and durability equivalent to those of engine-driven hydraulic excavators. In addition, the high energy onboard the excavator’s Proterra Powered battery system enables operation for up to 8 hours* when fully charged.

The electric power makes it possible to work comfortably in various work environments without worrying about noise and exhaust emissions, and is expected to be used for work in urban areas
and night-time construction work, etc. The zero-engine vibration will also help reduce operator fatigue.

As global awareness of climate change accelerates, Komatsu has declared to achieve carbon neutrality by 2050 with the aim of realizing a sustainable society. In collaboration with its partners,
Komatsu is developing electric construction equipment to achieve zero exhaust gas emissions and a significant reduction in noise emissions with the vision of developing safe, highly productive,
smart and clean workplaces of the future.

DANTOTSU Value is defined as customer value creation that generates a positive cycle of improvement of earnings and ESG resolutions in Komatsu’s mid-term management plan, entitled “DANTOTSU Value – Together, to “The Next” for sustainable growth”. Through this DANTOTSU Value, Komatsu will strive to create new values in order to take steady steps forward to the next
stage for the workplaces of the future and pass on a sustainable future to sustainable growth.

Through this DANTOTSU Value, Komatsu will strive to create new values in order to take steady steps forward to the next stage for the workplaces of the next generation.

*Operation of 5 to 9 hours in the PoC test, depending on the workload conditions.
