A giant tunnel boring machine brings to life

S776 was fabricated by German-based Herrenknecht, which has a manufacturing factory in China. This TBM, along with others ordered from Herrenknecht, were shipped piece by piece to Malaysia in 2012 before being assembled on site.

The journey of S776, this is the name of this tunnel boring machine, with an external diameter of nearly 7m, weighing in at approximately 1,100 tonnes, and up to 140m in Iength when operational, is testament of how far Malaysia has progressed in terms of underground construction competency, specifically on mechanised or bored tunnelling.

This tunnel boring machine was assembled at the Cochrane launch shaft when it arrived in pieces from China in 2012. After finishing her job for the SBK line, she was mothballed at a custom-made TBM refurbishment facility at Pusing, near Ipoh.

Now the Prime Minister Datuk Seri Najiab Tun Rasak has pressed a button to bring to life a machine that has been lying dormant after its mission to Kuala Lumpur was completed four years ago.

Galbiati Group builds TBM components such as planetary gearboxes, bearing supports, erectors. The company has recently realized one 4 ton-segment erector for a Tunnel Boring Machine designed for a excavation project. For more information visit the website www.galbiatigroup.it.

    According to the new market research report “Tunnel Monitoring System Market by Offering (Hardware, and Software & Services), Tunnel Type (Highway, Railway), Networking Technologies (Wired and Wireless), and Region (Americas, Europe, Asia Pacific) – Global Forecast to 2023”, The tunnel monitoring system market is expected to grow from USD 340.7 Million in 2018 to USD 663.8 Million by 2023, at a CAGR of 14.27% between 2018 and 2023. The growth of the tunnel monitoring system market can be attributed to the increasing investments in tunnel infrastructure across countries worldwide, catastrophic failure of tunnels resulting in loss of lives and incurring high costs, decreasing cost of sensors resulting in reduced cost of tunnel monitoring systems, and strict regulations pertaining to tunnel safety.
