The project group was early inspired to the solution used for mining (mines) around the world with the so-called trolley assist system, where mining trucks use largely standard railroad pantographs connected to the steep slopes.

Even older systems with trolley rods were found and that had special injection rods to cope with the connection of pantograph samples in speed to, in this case, rails.
