Ultra‑strong power support to meet the demands of large‑scale equipment.

As the application of new energy in large‑scale engineering projects continues to expand, the power requirements for charging equipment are steadily increasing. Guangzhou Ruisu’s 3 MW charger was specifically developed to meet this demand. With a peak output of 3 MW, it can effortlessly address the charging challenges faced by heavy‑duty electric mining trucks, electric heavy‑duty trucks, electric vessels, and other large‑scale construction machinery. Take electric mining trucks as an example: traditionally, these vehicles required lengthy charging times, significantly hampering mining operations. The introduction of the 3 MW charger, however, enables rapid full‑charge in a short period, allowing the trucks to return to service promptly and substantially boosting overall mine productivity—thereby driving the mining industry toward greener, more efficient practices.

Automated charging solutions enhance operational safety.

In certain specialized settings—such as green smart mines and ports—the demand for automated charging is steadily increasing. Ruisu Intelligent has innovatively introduced a 3 MW charger featuring an automated robotic arm‑based gun‑insertion system. In mining environments, when an autonomous electric haul truck enters the charging station, a fully automated robotic arm extends itself, precisely aligns with the vehicle’s charging port, automatically inserts the connector, and initiates the charging process. Once the battery is fully charged, the arm retracts autonomously, with no human intervention required throughout the entire procedure. This automated charging solution not only boosts charging efficiency but also significantly enhances operational safety in high‑voltage environments, offering a smarter, safer approach to powering large‑scale construction equipment and accelerating the automation of related industries.
