The amazing tunnel boring machines we’re checking out today were designed and created by Crossrail, a company that with the help of he TBMs creates a new world beneath London itself. These huge machines worked hard for 3 years to make the engineering dream come true. So, what makes them special?
Each tunnel boring machine features a series of trailers behind, rotating cuter head at the front and all the electrical and mechanical equipment you can think of. It can construct 6.2m diameter rail tunnels with its weight of approximately 1000 tonne. Furthermore, one tunnel boring machine is 140m in length. Its features are perfect for creating tunnel segments.
In the video below, you’ll see how these giant machines actually work – enjoy!
