Advances in autonomy
How the autonomous and emission-free ZE135 presents a powerful and sustainable alternative to conventional diesel machines.
Advances in autonomy
One of the main attractions at Bauma 2025 was a fully autonomous 15-tonne excavator, based on the electric ZE135. Presented as part of Hitachi and KTEG’s zero-emission product line at the event, it attracted huge crowds to the HCME stand’s demo area.
To operate autonomously, the ZE135 received its work instructions via a tablet and executed them independently. Its innovative autonomous control was developed in collaboration with Gravis Robotics.
While machines such as the ZE135 are in the development phase, they offer huge potential to transform the construction industry. With advancements in AI, robotics and machine learning, they will be able to take on more complex and delicate tasks, boosting productivity, addressing labour shortages, improving on-site safety and delivering more sustainable operations.
The ZE135 is equipped with a powerful 300 kWh battery that enables an operating time of up to six hours. The machine can be charged flexibly using DC charging via a CCS2 interface or AC charging with one or two interfaces with capacities of up to 63 A each. Additionally, the ZE135 can also be operated via cable to ensure continuous availability on the construction site.
Based on the Hitachi ZX135, the ZE135 offers the same high level of comfort and outstanding hydraulic performance as its diesel counterpart. The powerful hydraulics allow various attachments to be operated without restrictions, making the excavator ideal for a wide range of applications. The electric drive ensures quiet and emission-free operation, making it particularly attractive for urban job sites and sensitive environments.
The combination of zero-emission technology and artificial intelligence elevates the KTEG ZE135 to a new level of innovation and demonstrates the future of autonomous, emission-free construction.
“The KTEG ZE135 not only enables emission-free operation but also represents a significant step towards AI in construction through its autonomous control.”
