Hitachi Tests Super Electric Truck of 243 Tons in Mine in Zambia, Promising Zero Emissions and Energy Efficiency.
The Japanese company Hitachi took a significant step towards reducing emissions in mining by conducting tests with a super electric dump truck. The battery-powered vehicle is being evaluated at an open-pit copper and gold mine in Zambia. This is an important milestone in the industry’s search for more sustainable alternatives for heavy machinery.
Start of Tests in Mine in Zambia
Hitachi Construction Machinery’s initiative began in June 2021 and is an example of how technology is being applied to minimize the environmental impacts of mining activities.
The mining company First Quantum Minerals, which operates the Kansanshi mine in Zambia, is one of the main partners in this project.

1990s V8 engine running without gasoline: A German institute and an American startup have successfully made an engine run without gasoline and without emitting CO2, operating on ammonia and emitting only nitrogen and water vapor.
The goal was to test the feasibility of the electric truck in a real operating environment, where several Hitachi trucks are already in use.
Super Electric Truck: A Revolution in Mining
Hitachi’s new super truck is a significant advancement in the sector.
Based on the Hitachi EH4000 AC-3 model, the electric truck is a giant, measuring 14 meters long and 7.14 meters high, approximately equivalent to the height of a two-story building.
Its tires are equally impressive, measuring about 4 meters in diameter and 1.5 meters in width.
This truck has a payload capacity of 243.6 tons powered by a 2,500 hp Cummins engine.
One of the technological innovations of this model is regenerative braking, which allows the vehicle to recover energy during deceleration, reducing the need for frequent recharges.
In addition, the super truck is designed to operate in conjunction with a network of overhead charging lines.
This charging infrastructure is essential to ensure that the truck can operate continuously, even in a remote mining environment.
Environmental and Economic Benefits
The battery electric version of the super truck provides a significant environmental advantage: the complete elimination of diesel emissions.
This is especially relevant in Zambia, where 92% of energy comes from renewable sources.
By adopting this model, Hitachi is contributing to the reduction of carbon emissions associated with mining, a sector known for its heavy environmental footprint.
The use of electric trucks in mining not only helps protect the environment but can also reduce operational costs.
While the exact battery capacity of the super truck has not been disclosed, the dynamic charging configuration allows the battery to be smaller than would be needed in a conventional charging system.
This not only reduces the truck’s production costs but also maximizes the payload capacity.
Trends and Challenges in Sustainable Mining
The introduction of the super electric truck by Hitachi is part of a broader trend towards seeking more sustainable solutions in mining.
Other major companies, such as GM, Fortescue, Caterpillar, and Anglo American, are also developing and testing heavy machinery models with a lower environmental impact.
This evolution reflects a collaborative effort to minimize the harmful effects of mining on the environment.
However, the adoption of electric technologies in mining faces challenges.
The charging infrastructure and the need to adapt existing equipment and processes are critical aspects that need to be managed to ensure the effectiveness of these electric vehicles.
Hitachi’s experience in Zambia will provide valuable insights to overcome these challenges and advance the path to sustainability in mining.
Technological innovation and the partnership with First Quantum Minerals represent an important advance for the industry.
The success of the electric super truck could serve as a model for future implementations of electric technology in other mining operations around the world.
