IHI has been developing and releasing various shield tunneling machines, such as the world's largest large-diameter shield tunneling machines and rotating shield tunneling machines that will greatly improve tunnel construction efficiency. IHI is also leading supplier of automatic segment assembling systems and also provides various types of segments.
Above ground, IHI's mini-excavators, crawler carriers, crawler cranes and truck-mounted concrete pumps are active throughout the wide scene of civil engineering and construction. IHI has provided these machines not only to Japan but also overseas including the U.S.A. IHI also supplies machines for concrete casting. |
Large-diameter shield tunneling machineIHI has supplied many large-diameter shield machines, including the one used in the construction of the Tokyo Bay Aqualine tunnel.
|
| Horizontal Multiple-micro shield tunneling machineThis shield machine, used in the construction of box-shaped large-section tunnels such as road tunnels, can be flexibly adapted to any section shape. |
| | Rotating shield tunneling machineNew technology developed through joint research with users. It can excavate shaft from the ground, and continuously tunnel by right angles. |
|
| Combination circular shield tunneling machineBy extending the ends of the spokes of the cutters according to the rotation, non-circular cross sections, such as in the double track sections of subways, can be tunneled efficiently. |
| | Upward-facing shield tunneling machineThis shield tunneling machine tunnels upwards from an existing tunnel towards the surface. This minimizes the affect on the surface during construction of a tunnel, so that it is more friendly to the environment. |
|
| Double-O tube shield machineThis shield tunneling machine drills inbound and outbound lanes at a time, for example, for subways. This machine provides economic advantages with shortened construction time and reduced drilling soil volume and is employed in foreign countries as well. |
| | Rectangular type shield tunneling machineThis shield tunneling machine is used, for example, to construct grade-separating tunnels to solve congestion at
intersections or busy railroad crossings. It drills a large section by repeatedly moving back and forth between start
and drilling locations. |
|
| Automatic segment assembling systemIHI mechatronic technology has substantially improved tunneling efficiency and safety through the automated assembly of segments for tunnel walls. |
| | Jib climbing cranes for building constructionIHI's large jib climbing cranes, featuring large payloads and working radius capabilities, are used in nearly all skyscraper construction in Japan. |
|
| Crawler craneThe versatility and adaptability of IHI's family of small to large self-propelled crawler cranes make them a popular choice for many civil engineering and construction projects. |
| | Mini excavatorThe zero tail swing mini hydraulic excavator is ideal for excavation in narrow areas. |
|
| Truck-mounted concrete pumpThe long boom enables fresh concrete to be placed at any desired location. |
| | Crawler carrierProvides mobility, traversability, robustness, and ease of use and maintenance with consideration for
the environment and safety. |
