The NASA crawler-transporters are the largest land transport vehicles in the world.
Each crawler weighs about 2.7 million kilograms or about 6 million pounds.
They are 40 meters or 131 feet long and 35 meters or 114 feet wide.
And what absolutely magnificent works of design and engineering they both are
– these massive machines and their combined 8 thousand horse power engines have smoothly and faithfully carried all the
Saturn V rockets and all the Space Shuttles the 5 mile journey from the Vehicle Assembly Building to the Launch Pad.
