What exactly is the big advantage with the overhead handling system? I see videos of it online and think that it looks pretty complicated but I don’t see what the advantage is. Why not just have the track system be on the ground? Seems like it would be more maintainable.
I believe speed was the biggest factor. You can go a lot faster when you aren't contending with traffic. Vertical = multiple horizontal planes that don't interact much.
