Biggest electric vehicle in the world

Sissach, Switzerland, September 2018 – Back in 2016, eMining, a sub-company of the Swiss companies Lithium Storage GmbH and Kuhn AG, was asked to construct the biggest electric vehicle in the world. The so-called eDumper is now in operation and brings raw material from the stone quarry “La Tscharner” in Switzerland to a deeper located conveyor system. At the end of each day, the eDumper is plugged into a 600V/100KW connector from Rauscher & Stoecklin to recharge or to feed the grid with the generated energy.

The project, finished in April 2018, had some exciting challenges on the way. One of them was the construction of the biggest battery in the world. For Rauscher & Stoecklin, this project was an unusual application. It was the first “eMobility” project, thus Rauscher & Stoecklin invented for the male plug system a state-of-the-art finger touch protection. This resulted in having male and female connectors with IP4X protection, that ensures maximum safety.

Some specifications about the project:
• 121 tonnes total weight loaded
• 800 PS performance
• 50’000 l/year diesel savings
• 130 t/year CO2 savings
• 3 million CHF project costs

R&S has many years of experience in the mining industry. The connectors can handle the rough environmental conditions such as heat, dust, and icing. In our project, these aspects, as well as the safety of our personnel, were the top priorities and the reason we chose R&S as our partner on our side – and we are happy to have done so.
