Hydraulic excavator ZX135-7EB

Overview
The Hitachi ZX135-7EB is a next-generation 13-tonne class electric excavator engineered for sustainable construction and urban works. Fitted with a 660 V lithium-ion battery pack (198 kWh) and advanced electric drive systems, it delivers comparable productivity and attachment compatibility to conventional 13-tonne diesel models while eliminating exhaust emissions and significantly reducing noise. Dual-mode operation (battery and power-grid assist) ensures flexibility and extended uptime for urban, indoor and environmentally sensitive sites.

Key features

• Battery type: Lithium-ion
• Battery voltage: 660 V
• Battery capacity (full package): 198 kWh
• Dual-mode operation: battery-powered and power-grid assist (minimises charging downtime)
• Attachment compatibility and performance equivalent to 13-tonne diesel excavators
• Lower noise and vibration levels compared with diesel models
• Reduced operating and maintenance costs vs diesel (fewer moving parts, less frequent servicing)
• Available market: Europe

Benefits

• Zero exhaust emissions — suitable for urban, indoor and regulated environments
• Significantly lower noise and vibration — enables night work and operations near residences
• Comparable performance and full attachment compatibility with 13-tonne diesel excavators
• Lower total cost of ownership due to simplified drivetrain and lower energy cost
• Dual-mode capability (battery + grid) enables continuous operation even when standalone
