In 2002 the Falkirk Wheel was opened in Scotland. It replaced a series of 11 locks that connected to canals that had a difference in height of 115ft. As you can see in the videos, it is a giant wheel that spins to cars which contain the boats to be moved between canals.
Above is a time lapse showing it in motion and immediately below in explanation as to how it works. The final video shows a ride from inside a boat using the wheel.
