The crawler is also said to be the loudest vehicle on earth, even after taking into account it's six 9 foot long 3000 pound mufflers. All this makes things hot, so 500 gallons of water circulates through six radiators each with up to a 75 hp pump. This drinks from the combined 5,000 gallons of onboard fuel storage. It takes about 1,000 gallons to move the Shuttle and MLP between the Vehicle Assembly Building and the launch pad. Back on track, this means that the Crawler gets 42 feet per gallon, at 125.7 gallons per mile. Because when you round 0.007 mpg, it becomes zero.
#CRAWLER TRANSPORTER FULL#
This thing pokes along at 3 kph, 1.5kph loaded, and gets a full 0 mpg. In case you didn't keep tally that's 7630 horsies of Diesel power being made into 5800 kilowatts of electricity.
Two additional 150 kw generators are needed to raise and lower the platform. Jacking, steering, lighting, ventilation, and the onboard systems are powered by two additional 750 kilowatt generators turned by two more 1,065 horsepower diesel engines. This is all just to move the thing in one of two directions, forward and backward. These are powered by four 1,000 kilowatt generators in the main body, which are turned by two 2,750 horsepower diesel engines. The moving is done by 16 375 horsepower electric traction motors, two to a tread, four to a truck. This is all just to support the load, not to move it. The four trucks are 3 meters high and 12 meters long with two treads each. Since words can not be used to adequately describe its dimensions, let us break it down. The crawler is rectangular, 40 meters long and 34.5 meters wide, but the cargo contact points are positioned in a square 27 meters to a side The height of the Crawler can be adjusted independently between 6 and 8 meters by each of the four trucks. The "Crawler" is actually a platform full of generators and engines resting on 4 tracked "trucks". There are two, Hans and Franz, but I shall refer to the Crawler in the singular as they are identical and it makes it easier mmkay? It's big, it's old, it's damn near Pharaonic. NASA's Crawler-Transporters are the biggest, baddest, most kickass six million pounds of tracked vehicle in the known universe.
