World’s Largest Tunnel Boring Machine
This is the world’s largest tunnel boring machine built by Herrenknecht AG for Shanghai Changjiang Tunnel & Bridge Construction Development Co., Ltd. Two of them were used to dig 7.5 kilometers long double tunnel under Yangtze river in Shanghai.
The machine is 15.42 meters in diameter, 135 meters long and 2,300 tonnes of weight. It was digging 26 meters of a fifteen and a half meters wide automobile tunnel each day. Totally, 2.7 million cubic meters of ground have been excavated and removed during tunneling.

I want to have some pictures like this
How many of thease largest tunneling machines are there own by this company?
Are there more largest tunneling boring machines be build?
How many per week or month or year?
I may have a project in the near future that will require 1,500 of the worlds largest tunnel boring machines.
and 50,000 heavy trucks.
Building a 4 lane freeway all the way around the entire North America Canada and Alaska alone the shore line of the sea.
Building bridges over small sections of water of 30 miles from land to land or Island to Island where there is a mountain or hill these largest tunnel Boring machines will be use in places needed to drill and dig a tunnel for a freeway to get through if the tunnel has to be over 50 miles long in places or more.
freeways in farthest north of Canada no one never gone before.
More future projects of cities under ground or in 1 big one big indoor building cities in places where weather is to cold.
35,000 miles sea coastal 4 lane freeway and another 150 miles of 4 lane freeway tunnel under Chukchi Sea from Wales Alaska to Russia.

I AM AMAZED BY THE SHEER POWER AND MASSIVE SIZE OF YOUR MACHINES. MY SON WORKED WITH A HERRENKNECHT MACHINE IN PORTLAND, OREGON AS A PROJECT ENGINEER AND NOW ON TO S.F. BAY BY ANOTHER MANUFATURER. THIS ONE BY FAR IS THE MOST IMPRESSIVE I HAVE SEEN.
IS THE GUY SERIOUS WHO WROTE THAT LETTER? WHO IS FUNDING THIS SUPPOSEDLY TUNNEL PROJECT AROUND THE AMERICAS….DREAMER!
I think you are a wanker John :)
