However, on Decemprogress was halted after the machine damaged several cutter blades on a steel pipe. Tunnel boring began on July 30, 2013, with a projected end-date in December 2015. Hitachi Zosen Sakai Work in Osaka, Japan built the machine, and its assembly was completed in June 2013. Although she was built specifically to create the Alaskan Way Viaduct replacement tunnel in Seattle, she is now being shipped to different worksites. Big Berthaīig Bertha is the worlds largest tunnel boring machine at a length of 300 feet and a height of five stories. The LHC is 27 kilometers (16.78 miles) in circumference and buried 75 meters under the ground. The CERN laboratory, and the underground LEP tunnel, is located near Geneva on the France- Switzerland border. The LHC is operated by CERN, or the European Organization for Nuclear Research. New discoveries with the LHC happen all the time, as well as record-setting operations.
The LHC took decades to plan and build, and the work of thousands of scientists, engineers, and technicians. The LEP tunnel it sits in was completed 20 years earlier in 1988. It is a particle collider that first fired up on Septemhowever, its conception and construction happened in waves. The Large Hadron Collider is the largest machine ever built, which is a bit funny because the reason it was built was to study the smallest particles in the universe… subatomic particles. Here are some of the world’s largest machines ever built. The sheer mass of these beastly machines are testaments to the ingenuity and inventiveness of humankind.
Some of these titans of engineering have been built in recent years, and some have held their impressive records for 20 years. Although feats of engineering and technology happen every day, there’s nothing more impressive than the largest machines in the world.
