Each individual dish is up to 40 feet in diameter (12 meters) and weighs 115 tons.  Dishes are being provided by European, Asian and American partners.

ALMA employs two transporter vehicles for moving the individual telescope dishes. Each has 28 wheels and weighs 130 tons. Two engines generate 1,400 horsepower. The vehicle can travel 7.5 mph (12 km/hr) when carrying a telescope.
