Hitching a lift with an ALMA transporter

The ability to reposition its antennas is part of what makes the Atacama Large Millimetre/submillimetre Array (ALMA) such a powerful telescope. ALMA uses two of these enormous transporters, which have been named Otto and Lore. The twin vehicles are 20 metres long, 10 metres wide and 6 metres high, and each has 28 tyres.
