The ALMA Transporter (IMAGE) ESO Caption The ALMA antenna transporter is motorised by 2 powerful engines of 500 kilowatts each -- i.e. as much as twice a Formula 1 engine -- that drive individually each of the 28 wheels. These powerful engines are necessary to climb the 10 percent slopes that exists on the Chajnantor site and to bring the 240 tons of the vehicle and antenna from the 2900 meter high base camp to the observing site at 5000 meter altitude. The transporter has on board a power generator to keep the antenna and its cryogenic systems alive while being transported. Credit ESO Usage Restrictions All ESO photographs are Copyright (c) ESO.
