(Video) Watch Liebherr’s autonomous hauling concept designed with just two tires and an axle

Liebherr's concept for a new way to autonomously haul material, the S1 Vision, is born from a desire to rethink truck design and focus only on core components. The S1 Vision is just a single axle and two tires and is designed to be scalable, with a payload ranging from 220 kilograms up to 131 tons. Because of this payload versatility, the S1 Vision can be adapted for various applications, including earthmoving, farming and agriculture, construction, and mining.  

The innovative design is a collaborative effort between Liebherr Corporate Ventures AG, the Group's business unit for innovation and technology development, and Liebherr Mining Equipment Newport News Co., the Group's mining truck R&D and manufacturing facility. The technology has now become an innovation beyond the mining division and could prove itself for several product segments — Liebherr has therefore decided to continue working on the project to optimize synergies. 

The design can be seen at bauma 

The S1 Vision will be displayed at this year's bauma exhibition from April 7 to 13 in Munich, Germany. The design has also been nominated for the bauma Innovation Award in the Mechanical Engineering category. Winners of the award will be decided on the practical relevance of a solution and its economic potential, digitalization, environmental aspects, sustainability, resource efficiency, and the humanization of the workplace. 

Designed for superior manoeuvrability 

The truck can operate effectively on a single axle with a self-levelling system that ensures maximum stability and safety, even on bumpy or rough terrain. This technology significantly reduces the risk of tipping, providing smooth and secure operation across various environments. 

The S1 Vision's zero-turn radius means the truck can easily turn on the spot, making it ideal for applications in tight spaces that require precise movements and flexibility. 

Technology for today and tomorrow

This haulage concept is designed with cutting-edge technology in mind. The S1 Vision is powered by an electric drive, providing a haulage solution that significantly reduces greenhouse gas (GHG) emissions during operation. It's also equipped with advanced sensors so the truck can navigate independently, avoid obstacles, and efficiently manage traffic. 

Also, if multiple S1 Vision trucks are operating in one location, the system allows them to connect and share real-time information, which optimizes fleet operations, reduces congestion, and enhances overall efficiency. 

Easy serviceability and transportability

The vehicle's design allows for rapid maintenance, with critical components easily accessible for quick servicing. Wear parts can be replaced efficiently and the electric drive reduces overall maintenance work, which further minimizes downtime and increases operational efficiency. 

The customizable design and lightweight structure of this concept means the S1 Vision can be easily transported, lowering logistics costs and GHG emissions — all of which contribute to a sustainable, cost-effective haulage solution suitable for diverse operational environments.
