The ALMA antenna transporter (rear view)

When lifting an antenna, the driver will be at the rear of the vehicle and manipulate it as a 'toy-car', to achieve the best possible precision and to watch as closely as possible the critical operation. The transporter will be able to position the antennas with millimetric precision and is therefore helped by a dedicated guiding system. As the transporters will be operated at an altitude with significantly reduced oxygen levels, a range of redundant safety devices were installed to protect both personnel and equipment from possible mishaps or accidents.
