Zijin Longking ZL230E: The Engineering Reality of 350-Ton Electric Haulage

Zijin Longking officially debuted the ZL230E mining truck on August 10, 2026, in Longyan City, Fujian Province. As a 350-ton gross vehicle weight (GVW) machine with a 230-ton payload capacity, it currently stands as the largest-tonnage pure electric mining truck in China. The vehicle utilizes a 1,400 kWh battery pack capable of a 10% to 90% state-of-charge (SoC) transition in 25 minutes, a performance benchmark that addresses the traditional bottleneck of downtime in open-pit mining operations.

The Tech TL;DR:

• High-Capacity Power Density: The ZL230E employs a 1,400 kWh battery, exceeding the energy capacity of 23 Tesla Model 3 units to sustain heavy-duty, high-intensity mining cycles.
• Autonomous Integration: The platform is built for tight integration with EACON’s autonomous stack, which currently manages over 3,100 haulage units across 40+ global mining sites.

Architectural Breakdown: Power Distribution and Thermal Management

The ZL230E moves away from traditional mechanical transmissions, opting for a multi-axle central distributed independent drive architecture. According to technical specifications provided by Zijin Longking, the system leverages dual 800kW electric motors. This configuration allows for real-time torque vectoring and power matching across drive axles, which is critical for maintaining velocity on steep, high-rolling-resistance mining ramps.

While the manufacturer emphasizes its “high-rigidity, large-cross-section frame structure,” the efficiency of the power delivery is tied to its intelligent energy management software. This is not merely a vehicle procurement; it is a shift toward a “Wind-Solar-Storage-Charging-Equipment” ecosystem.

Operational Reliability and Cybersecurity Implications

The partnership with EACON brings a full stack of perception, decision-making, and cloud-based dispatch logic to the ZL230E.

Beyond cybersecurity, the physical reliability of the 350-ton frame relies on redundant braking and steering loops. According to company documentation, the ZL230E utilizes a multi-level redundant safety architecture.

Future Trajectory

As Zijin Mining aims to replace its fuel-powered fleet within the next three years, the success of the ZL230E will serve as the primary test case for scaling battery-electric haulage in ultra-large open-pit operations. The performance data recorded at the Julong Copper Mine—where previous 150-ton units achieved 90% availability and a 17% reduction in energy consumption—provides a baseline for the ZL230E’s expected performance in the coming quarters.
