I know everyone is dying to know. It's 43 tones and it's in the Cleveland Federal Reserve. Now that is one heavy door! sources: http://www.locksmiths-r-us.co.uk/blog/index.php/biggest-locks/ http://surferjerry.com/uncategorized/worlds-largest-bank-vault-door/
It's not technically a door, but the rotating cylinder that controls access to the gold vault at the New York Federal Reserve is 90 tons.
your not going to move that much weigth by hand. Read more: http://www.cointalk.com/t188519/#ixzz1TsyvP6rM One time I entered a nuclear missile control room in Utah which had a huge metal door. We pulled on the door for a while & it began to open. Once it started moving, we began pushing the other way to stop the motion. We opened it just enough for us to squeeze through & reversed the process to close it. What I'm saying is that you can move a huge mass by hand providing you can break the static friction & remember that you have to stop it once you get it moving.
Here is a youtube video of a guy pulling a railcar that weighs over 76,000 lbs. He is pulling against a rope though. http://www.youtube.com/watch?v=dz866xD0pjU
G:thumb: One hex of a large vault!!! I could use one like that but for what lock out the world lol!!!
You say your not going to move that much by hand, and then proceed to give an example where you did. OK maybe it wasn't quite 43 tons but it is possible to move huge weights by hand. It is just a matter of overcoming inertia and friction.
