en.Wedoany.com Reported - XCMG (Xuzhou Construction Machinery Group Co., Ltd.) announced in mid-June 2026 that its self-developed world's largest tonnage pure electric hydraulic excavator, the XE700EV, has completed its first delivery test at a large open-pit mine in East China. This 70-ton class pure electric excavator is designed for mining and heavy earthmoving operations, with an operating weight of 76.2 tons and a standard bucket capacity of 4.5 cubic meters. This delivery marks a key leap for Chinese construction machinery from catching up to leading in the field of new energy large-scale mining equipment.
Founded in 1989 and headquartered in Xuzhou, Jiangsu Province, XCMG is a leading Chinese construction machinery manufacturer, with products covering cranes, earthmoving machinery, mining machinery, concrete machinery, and more. The XE700EV is XCMG's flagship product in the new energy mining equipment sector. According to official product data from XCMG, the model is equipped with two lithium iron phosphate power battery packs manufactured by Contemporary Amperex Technology Co. Limited (CATL), with a total capacity of 1200 kWh and a comprehensive operating time of 6 to 8 hours. The equipment features dual high-power permanent magnet synchronous motors with an energy conversion efficiency exceeding 96%, supports mainstream DC charging stations on the market, with a maximum charging current of 800 to 1000 amps, and can fully charge the entire battery pack in just 1.5 hours. The machine structure has been reinforced and upgraded, with the boom and arm using integrated thickened steel. The standard heavy-duty mining undercarriage is paired with widened tracks, achieving a fatigue service life exceeding 12,000 hours. The cab is equipped with a 10-inch intelligent display for real-time viewing of all machine data, along with a full set of intelligent monitoring systems for real-time monitoring of voltage, temperature, and motor status.
According to XCMG, the XE700EV pure electric excavator achieves zero emissions and low noise during continuous heavy-duty operations such as mine stripping and loading, delivering strong power output and operational efficiency comparable to traditional fuel-powered models of the same tonnage. Comprehensive energy costs are reduced by over 60% compared to fuel-powered models, and each unit can reduce carbon emissions by approximately 400 tons per year for the mine. Based on official XCMG estimates, the annual operating cost of the XE700EV can save about 900,000 RMB compared to a fuel-powered excavator of the same tonnage. To ensure customer operational efficiency, XCMG's Excavator Division provides 24-hour on-site mine support services, establishes standardized service stations locally, and stocks key spare parts and charging support equipment.
The mine receiving this equipment has already pioneered the use of unmanned electric mining trucks, photovoltaic energy storage, and low-carbon operations. The addition of the XE700EV will further complete the full-process closed loop of green mining, low-carbon transportation, and efficient operations at the mining site. This delivery test is a significant demonstration of XCMG's technical strength in the new energy field, providing large-scale, electrified equipment solutions for the global mining industry's green transformation.
