- About the machine
- This is a boring machine with a diameter of φ6.99 m. It was delivered for the Manila Urban Subway Project CP101 Construction Zone, the first subway project to be underway in the Republic of the Philippines. Six mud earth load shield machines were used to construct six subway tunnels for a total length of 9.5 km. Excavation with the first machine started in January 2023. This construction has garnered attention from the citizens of the Manila Metro Area as it is the first subway construction project in the Philippines, and there are high hopes that this subway will be the key to reducing traffic congestion.

- About the machine
- This is a boring machine with a diameter of φ6.63 m. Three of these machines were delivered for the Singapore Subway Thomson Line. In order to excavate composite ground consisting of a base rock layer (called “ Bukit Timah Granite”) and sand gravel layer, the machines were built with specifications that would allow them to perform high-speed rotation of the cutter heads equipped with multiple disc cutters for excavating rock base. Excavation of earth used a slurry type machine with discharge using a fluid conveyance system.

- About the machine
- Dubai in the United Arab Emirates has been facing serious traffic congestion in the city due to its remarkable economic growth and increase in population. What was planned for eliminating this problem was the Dubai Metro, the first urban railway transport system in the Middle East. Three boring machines with a diameter of φ9.56 m were delivered for excavating tunnels with a total length of approximately 10 km. The Dubai Metro started operation in September 2009, and all lines are fully automatic.

- Client
- Madrid Calle 30
- Customers
- Dragados-FCC Joint Venture
- About the machine
- This is a large-bore-diameter boring machine with a diameter of φ15 m. It contributed to the construction of an expressway tunnel in Madrid. The construction deadline was extremely short, and it required an excavation speed of 360 m a month, so a high-power boring machine was designed and produced. The boring machine was delivered to the site in November 2005. Excavation started in April 2006 and finished in October 2006. The average excavation speed was 534 m a month, with the highest being recorded at 800 m a month. The “M30” orbital motorway, with a length of approximately 35 km through the city of Madrid, faces some problems resulting from increased traffic volume, such as chronic congestion, worsening of the nearby environment due to exhaust gas, and segmentation of the urban area. The tunnel boring machine contributed to solving the issues caused by making the motorway underground.
