Hitachi Launches ZX135-7EB Battery Excavator Worldwide

Hitachi Construction Machinery NV (HCME) has officially launched the ZX135-7EB, its largest battery-electric excavator, marking a significant expansion in the company’s zero-emission construction equipment portfolio. Weighing 13 tons, the ZX135-7EB is designed to meet the growing need for environmentally friendly machinery in urban and residential environments where noise and exhaust emissions are restricted.

The dual-mode excavator supports round-the-clock operation, combining sustainability with efficiency. Hitachi’s latest offering reflects the construction sector’s shift toward low-emission machinery and showcases the company’s commitment to reducing carbon footprints while maintaining high operational standards. The ZX135-7EB will make its public debut at CONEXPO 2026 in Las Vegas this March.

Dual-Mode Technology Drives Efficiency and Continuous Operation

The ZX135-7EB is engineered for flexibility through its dual-mode operation. It runs on a 198 kWh lithium-ion battery for emission-free performance and can also connect to a 400V AC three-phase power supply in grid-assist mode. This dual functionality ensures uninterrupted operation while delivering performance comparable to the diesel-powered ZX135-7 model.

The excavator’s electric drive system includes remote monitoring features, allowing operators to track battery status and motor load factors in real time. Maintenance costs are reduced compared with diesel alternatives, and extended operational hours increase productivity. Safety is enhanced through an Aerial Angle camera system, providing a 270-degree bird’s-eye view of the working area. This makes the ZX135-7EB especially suitable for congested urban and residential construction sites.

Hitachi’s Growing Eco-Friendly Machinery Portfolio

Hitachi has significantly expanded its line of zero-emission equipment, focusing on both electric and hydrogen-powered excavators for a variety of use cases. The ZX135-7EB complements smaller battery-electric models such as the ZX17U-6EB, ZX55U-6EB, and ZX85-6EB. In addition, Hitachi offers hydrogen-powered ZE-series machines, including ZE17, ZE55, and ZE85, developed in partnership with Kiesel Technology GmBH.

Norihiko Kinugawa, Product Manager at HCME, emphasized that the ZX135-7EB “combines robust build quality with a charging system designed to support daily operation,” highlighting the machine’s suitability for urban construction projects while maintaining safety and productivity standards.

Strategic Expansion and Financial Backing

The launch of the ZX135-7EB comes shortly before CONEXPO 2026 and follows Japan’s Itochu Corp increasing its stake in HCME from 20.4% to 33.4%. The investment aims to support global expansion, particularly in North America. Itochu plans to accelerate collaboration in sales, rentals, finance, mergers and acquisitions, and new business areas. The corporation will also leverage its expertise in governance, logistics, finance, and ESG to strengthen HCME’s management foundation and enhance global competitiveness.

The financial and operational strategy behind this launch positions Hitachi to meet rising demand for zero-emission construction equipment, aligning with sustainability goals while offering high-performance, low-maintenance solutions for large-scale projects.

Conclusion

The ZX135-7EB reinforces Hitachi’s leadership in sustainable construction machinery. Its dual-mode operation, safety features, and urban-friendly design allow for productive, eco-conscious construction operations. Combined with strategic financial backing from Itochu and the company’s expanding portfolio of electric and hydrogen-powered machines, HCME is poised to drive the future of zero-emission construction globally.
