The ALMA antenna transporter
The first of the two 130-ton ALMA antenna transporters was named ''Otto'' on 5 October 2007 to highlight the remarkable achievement these unique machines represent. These vehicles will operate at 5,000 metres altitude, where the air is rare, and they are able to place 115-ton antennas with a precision of a few millimetres. Image taken October 2007.
