The Antikythera mechanism is more valuable than Mona Lisa !
says professor Michael Edmunds from Cardiff University, who led a 2006 study of the mechanism !
Honestly, this is one of the most mysterious, extraordinary, fascinating & interesting machine I’ve ever seen in my life ! The Antikythera mechanism is one of the most remarkable inventions of the ancient world came to light in 1900 when a Greek Sponge diver discovered the wreck of an ancient Greek or Roman cargo ship that had sunk off the Greek island of Antikythera around 80 B.C.E ! more “Antikythera mechanism – The most ancient & mysterious Greek machine !”
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 !
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.
Human started with just wheels for travelling & transportation purposes at first. Then came bikes, cars & trains which could be driven on land. The next difficulty was to overcome the vast oceans & seas which led to invention of ships. Engineers are still finding ways to make today’s vehicles more better & efficient even though we have achieved success in almost every mode of travelling & transportation. One of the extraordinary machine in history of vehicles is hovercraft. Lets see how does a hovercraft works ?more “How does a hovercraft work ? | Design & Application”
It’s big… no it’s bigger… sorry it’s the BIGGEST truck in the world !
Whenever I see it, it gives me a feeling like the truck is trying to say me – GET THE HELL OUT OF MY WAY !!!
You probably enjoyed the childhood by making the construction scenes, playing with the trucks making sounds – Vroom broom…! Our favorite among the collection of toys were the backhoe loader(well known as JCB) & the dump truck because they were different from others. We love to fill the bed with mud, rocks & made mechanical voices while dumping it.
In real world dump trucks are used to haul loads of rocks, dirt, sand, coal etc. And obviously the more a dump truck can carry, the less it costs the mining company per load to haul the resources.
For several years the largest dump truck was the Caterpillar 797B.
This massive beast was so big that it couldn’t be driven even on a highway. Instead it had to be transported in pieces & assembled at the construction site. Unbelievable, isn’t it ?
But, human nature – “never satisfies”. So the title of largest dump truck went to a new vehicle – The mighty BelAZ 75710.
Now this thing is really really at the edge of massive-ness. It is manufactured by BelAZ in Belarus.
So how big is it ?
If u stand beside it, you would barely reach to the center of it’s tires or in a better way – the radius of tire is greater than your height ! Each tire costs $42,000 which also explains why this entire shit costs over $6 million !
It is as long as two buses parked end to end & believe me – it is more heavy than Airbus A380 – the world’s largest passenger airliner !
It is 20.6 metres long, 8.16 metres high, and 9.87 metres wide. The empty weight is 360 tons & it can carry 450 tons of load !
Instead of a single engine, the Siemens MMT 500 drive system is powered by two 65-litre 16-cylinder diesel engines, each with 2300 horsepower. 2 engines working together give a power of 4,600 hp – 4.6 times than the Bugatti Veyron Super Sport, the fastest car in the world !
Now, if you are wondering why BelAZ chose electric motors to drive this thing; the company wanted to maximise fuel efficiency while also meeting tougher environmental regulations that govern vehicle emissions related to mining operations.
Now this is the first time I have used the exclamation marks so frequently – almost after every line. Well it had to be done. Yea, you know it expresses the feelings !
So once more…
All hail mighty BelAZ 75710 !!!!!!!!!!!!!!!!!!!!!!!!!
