We Humans, being a couple of feet high, weighing barely a quintal are capable of making & building things
million times bigger & heavier than us & we have proved it. Hats off to those engineers who have built them !
So lets have a look at the top 10 biggest machines of all time which we’ve never imagined of !
These are the machines which are so big that you might have to walk a kilometre or so to view them completely.
So get ready to get your jaw drop…!
The countdown begins… more “The Top 10 Biggest Machines in the World !”
Human being started using animals to carry load when it exceeded his carrying capacity. Then he started building machines to carry even more load & to transport faster. Today huge trucks carry massive amounts of load & the best example is the biggest truck in the world – The BelAZ 75710 which can carry 450 tons of dirt. Still, there was something left, something to be made to carry these massive rockets & space shuttles. So how are they transported ? The answer is – CRAWLER !
Crawlers are a pair of tracked vehicles used by NASA to transport rockets & space shuttles from NASA’s Vehicle Assembly Building (VAB) to the Launch Complex 39 !
Launch Complex 39 (LC-39) is a rocket launch site at the John F. Kennedy Space Center on Merritt Island in Florida, USA. Launch Complex 39 is composed of three launch pads—39A, 39B and 39C.
The Crawlerway is a 40 m double pathway at the Kennedy Space Center in Florida. It runs between the Vehicle Assembly Building and the two launch pads at Launch Complex 39.
- The crawler-transporter is the largest self-powered land vehicle in the world.
- The crawler has a mass of 2,721,000 kilograms (5,999,000 lb) and has eight tracks, two on each corner.
- The vehicle measures 40 by 35 metres (131 by 114 ft). The height from ground level to the platform is adjustable from 6.1 to 7.9 m (20 to 26 ft), and each side can be raised and lowered independently.
- As of 2003, each crawler had 16 traction motors, powered by four 1,000 kW (1,341 hp) generators, in turn driven by two 2,050 kW (2,750 hp) V16 ALCO 251C diesel engines.
- The crawler’s tanks holds 19,000 liters (5,000 U.S. gal) of diesel fuel, and it roughly burns 296 liters per kilometer (125.7 U.S. gal/mi).
- The new upgrade to one of the crawlers increased it’s capacity from 5,400,000 to 8,200,000 kg.
- The crawler is controlled from two control cabs located at either end of the vehicle, and travels along the 5.6 km (3.5 mi) crawlerway.
- The maximum speed of crawler is 1.6 km/h (1 mph) loaded, or 3.2 km/h (2 mph) unloaded.
- The average trip time from the VAB along the Crawlerway to Launch Complex 39 is about five hours.
- Kennedy Space Center has been using the same two crawlers, nicknamed “Hans” and “Franz”.
- Each of the two crawlers cost about US $14 million !!!
- In their lifetime, they have traveled more than 5,500 km (3,400 mi), about the same driving distance as from Miami to Seattle.
