Huge new generation tunnel boring machines that  can excavate rock walls, remove the material and   install the concrete pieces, leaving the tunnels  ready for the construction of roads or railways  These are, the 10 Biggest Tunnel  Boring Machines in the World 10. Dame Whina Cooper  It is a closed shield tunnel boring machine,   which measures 7.1 meters in diameter  and has been manufactured in Germany  measures 130 meters in length and  has a total weight of 910 tons  its cutting head breaks up and removes  the material and installs concrete   segments creating the tunnel walls uses hydraulic cylinders to propel   itself forward from newly placed segments  and can advance up to 32 meters per day  this tunnel boring machine will be used until  2022 to build a 1.6 kilometer long tunnel   under the city center of Auckland in New Zealand,  which will improve the public transport network 9. Florence  It is a closed shield tunnel boring machine,   which measures 9.1 meters in diameter  and has been manufactured in Germany  measures 170 meters in length and  has a total weight of 2,000 tons  It has 3,500 kilowatts of installed power  and a torque of 16,300 kilonewton meters.  works with a crew of 17 and the  support of another 100 on the surface  works 24 hours a day, 7 days a week  and can advance 15 meters per day  this tunnel boring machine began to be used  in 2021 to build a 16-kilometre-long tunnel   in the south-east of England  that will serve as a rail link 8. La Tapatía  It is a closed shield tunnel boring machine,  which measures 11.5 meters in diameter   and has been manufactured in  Germany by the company Herrenknecht  measures 105 meters in length  and weighs more than 2,000 tons  It has 6,300 kilowatts of installed power  and a torque of 44,000 kilonewton meters.  was used from 2016 to 2018 for the construction  of a 5.4-kilometer-long tunnel in Mexico  this underground section is part of a train  line that connects several municipalities   in the state of Jalisco installed a total of 15,000   concrete voussoirs to form the more  than 2,000 rings that make up the tunnel 7. TBM S-947  It is a simple shield tunnel boring machine,  which measures 13.9 meters in diameter   and has been manufactured in Germany measures 75 meters in length   and has a total weight of 2,000 tons It has 3,500 kilowatts of installed power   and a torque of 6,300 kilonewton meters. was built specifically for the   reconstruction of the Belchen tunnel which  is located in the mountains of Switzerland  the tunnel boring machine began to  be used in 2016 and managed to drill   and secure up to 90 meters of tunnel per week in total it took 16 months to complete the work   and allowed the 3.2 kilometer long  tunnel to be rebuilt to be used safely 6. Caucasus  It is a simple shield tunnel boring machine,  which measures 15.08 meters in diameter   and has been manufactured in China, by  the China Railway Tunnel Group company.  It measures 182 meters in total  length and weighs 3,900 tons.  It has 9,900 kilowatts of total power  and a maximum thrust of 22,000 tons.  began to be used in the mountains of Georgia  in 2019, to build a 9-kilometer-long tunnel  this tunnel crosses the caucasus mountains and  joins a key highway linking several countries  this project is part of a set of maritime  and rail links between China and Europe 5. TBM S-317  It is a mixed shield tunnel boring machine,  which measures 15.4 meters in diameter and   has been manufactured in Germany measures 135 meters in length   and has a total weight of 2,300 tons It has 3,500 kilowatts of installed power   and a torque of 34,000 kilonewton meters. the tunnel boring machine is designed to withstand   water pressures of over 6 bar and excavate a  mixture of sand, clay, rocks and groundwater  This machine was used in 2006 in China, to build  a tunnel under the Yangtze River in Shanghai   that measures 7.4 kilometers in length and is  located 65 meters deep under the river bed. 4. Martina  It is a closed shield tunnel boring machine,   which measures 15.6 meters in diameter  and has been manufactured in Germany  measures 130 meters in length and  has a total weight of 4,500 tons  It has an excavation area of 192 square meters  and its cutting elements are made of tungsten.  It has 12,000 kilowatts of installed power  and a torque of 94,000 kilonewton meters.  it can advance up to 24 meters per day  and had a cost of 60 million dollars  this tunnel boring machine was used in 2013  for the construction of the Sparvo tunnel in   Italy, which has a total length of 2.4 kilometers 3. Santa Lucia  It is a closed shield tunnel boring machine,  which measures 15.8 meters in diameter   and has been manufactured in Germany measures 130 meters in length   and has a total weight of 5,000 tons It has 17,600 kilowatts of installed power   and a maximum thrust of 314,000 kilonewtons. it can extract 2,100 tons of material per hour   and was designed to protect workers from possible  methane gas leaks during material extraction  It was used in 2017 by the Pavimental company  to build a 7.7-kilometre-long tunnel in Italy,   which served to improve the connection  between the cities of Bologna and Florence 2. Bertha  It is a closed shield tunnel boring machine,  which measures 17.5 meters in diameter   and has been manufactured in Japan by  the company Hitachi Zosen Sakai Works.  It measures 99 meters in total length  and has a total weight of 6,700 tons.  It has 22,000 kilowatts of installed power  and a maximum thrust of 392,000 kilonewtons.  It has a rotational speed of up  to 1.8 revolutions per minute   and a torque of 147,000 Kilonewton meters.  This tunnel boring machine was used  in 2017 to create a 3.2 kilometer   long tunnel under the city of Seattle in the  United States and it cost 80 million dollars 1. Tuen Mun  It is a mixed shield tunnel boring machine,   which measures 17.6 meters in diameter  and has been manufactured in Germany  measures 120 meters in length and  has a total weight of 4,800 tons  It has 5,600 kilowatts of power and  a torque of 27,000 kilonewton meters.  this tunnel boring machine was used  to build 2 underwater tunnels of 5   kilometers in length in the Hong Kong region construction began in 2015 and the tunnel   boring machine had a performance  of more than 30 meters per day  the tunnels are located 60 meters below sea  level and were opened to vehicle traffic in 2020 thank you guys so much for watching this  video if you enjoyed it please leave your   comments saying about what other types  of machines you would like to see a new   video about if you indeed like this video  please leave a like below and share it
