Product Overview

Prochain®

With our system, we offer unrivalled efficiency and speed combined with maximum flexibility. Thanks to our patented technology, we are the only supplier to date to procure a continuous rotating automation solution with a simultaneous supply of pneumatics, electricity, and bus.
In the last ten years, we have been able to inspire small companies to internationally operating large corporations with our solutions.


Initially, the production of goods could only be scaled up if you had more hands at your disposal. In the industrialization age, machines were invented to workers and make them more efficient. In recent decades, the workforce has been replaced more and more by industrial robots. The advantage is obvious – robots can be designed to move much more load. They are also faster and never get sick. However, since they only ever imitate human movements, they are merely an evolutionary step to manual labor. In consequence, industrial robots share the physical limits of human movements, even if these have been shifted to higher levels.


In order to further improve productivity, we need to change the perspective.
Take locomotion as an example. Here, too, robots are being taught to walk. The systems are becoming more and more sophisticated and can now jump over obstacles or do somersaults. But does that make them the best and most efficient way to get around?
Mankind invented the wheel thousands of years ago and no one would think of equipping a locomotive or a car with legs. No! The most efficient way to roam is and remains the wheel!


With our ProChain® technology, we bring the efficiency of the wheel to automation! No more “empty runs” and no more acceleration limits.
It is time to free automation from its human legacy.
