Check out this unique surface-lift in Switzerland that is able to turn multiple directions using a simple, yet genius, design.
The video excellent job of breaking down the technical terms in an approachable and understandable way for an idiot like me.
You can skip ahead to the 5:30 mark of the video if you want to see just the information about the lift, but the minutes leading up provide excellent insight as to why this particular lift is so incredible.
