Moving around ALMA antennas

The Atacama Large Millimeter/submillimeter Array (ALMA), an international partnership of Europe, North America and East Asia in cooperation with the Republic of Chile, is the largest astronomical project in existence. Consisting of 66 100-ton individual radio telescopes that can be moved to zoom in on a patch of sky. In the video you can see how do they move them around the desert…

For our newest ESOcast, we pose this puzzle: how do you move a 100-tonne giant ALMA antenna 30 kilometres up onto the oxygen-starved Chajnantor Plateau, 5000 metres above sea level and finish the job with millimetre precision?
