Infrastructure

MENU

Our industrial hoses are playing their parts in construction machinery, factories, and civil engineering sites. Seismic isolation rubber bearings are protecting our highway overpasses, bridges, and other parts of the infrastructure network from the threat of earthquakes. Sumitomo Riko products are everywhere contributing to the building of industrial infrastructure and the development of public transport. We have the top market share* in Japan for anti-vibration rubber used on trucks for rolling stock, including the Shinkansen, and many are also in use in other countries. We are contributing to disaster recovery in Japan and to the construction of facilities for the Tokyo Olympics, as well as to the building of infrastructure overseas, especially in developing nations.

Heavy Machinery

We utilize our rubber compounding, molding technology, metal fitting processing, and bonding technology to provide ultra-durable hoses that meet the needs of various industrial machines. Our hydraulic hoses feature a multi-layered structure consisting of layers of rubber and wire to provide both resistance and flexibility. The use of special compound rubber imparts resistance to weather and long-term durability.

Industrial Hoses

High Arrow

Used by attaching to the end of a concrete pump that pumps ready-mixed concrete at construction sites. It is lightweight, flexible, and features excellent workability. A special rubber compound and structural design provides improved abrasion resistance and realize a longer service life.

ELSTAR

They are used to convey water, mud, and concrete, and you can find them helping with construction deep underground. Over many years, they have contributed to the development of our towns and cities, being used in a variety of major projects.

Bullet Trains and Railway Rolling Stocks

Sumitomo Riko's rubber products are more than a match for the requirements of infrastructure where long life and durability are required. The anti-vibration rubber for rolling stocks reduces the vibrations from rails, are able to withstand constant vibration and harsh environmental conditions and are widely used widely in high-speed railways both in Japan and around the world.

Anti-vibration Rubber for rolling stocks

Cylinder Rubber Axle Springs

Mono-link Bushes (Link Bushes)

Radius Arm Rubber Bushes

These rubber products are used in the truck parts of trains to significantly reduce vibration generated from the track. They are used for the Shinkansen as well for most domestic railroad rolling stocks. They are also widely used overseas.

Bridges, Highways and Railways

We develop rubber bearings that safeguard bridges such as elevated highways and bridges from environmental changes and disasters.
These have the effect of reducing the inertial force felt when an earthquake occurs and contribute to the improvement of the seismic performance of the bridge.
We safeguard social infrastructure with our main products, our "THD" seismic isolation rubber bearings, which feature superior stable temperature dependence, and our "HDR-S" high damping rubber bearings.

The "Bizen ♡ Hinase Bridge" in Okayama is an example of a construction project where our rubber bearings are used

Rubber Bearings for bridges

Disc rubber bearings of high contact pressure "DRB"

Able to be installed in small spaces at new and existing bridge. Utilizing urethane rubber and a disk bearing structure, this is a product that realizes high contact pressure.

Landscape Materials

We can offer products for a variety of aesthetics needs. We contribute to improving landscape and the environment with a variety of products, including the "MOLD STAR", a concrete mold with a rich variety of designs that harmonize with the natural surroundings, and buried formwork used in landslide prevention works and sheet metal restoration applications.

"Tan Tan Tunnel" in Hyogo is an example of a construction project where our rubber bearings are used

Panels for refurbishment of open channels

High-strength precast panels and concrete filler covering the surface of aged steel pipe sheet piles extend the life of channels and reduce life cycle costs.

Buried formwork "PATWALL"

This product has already been used in a wide variety of applications, including cave-in prevention, erosion control, and waterway restoration. Because the pieces are light, the construction can be performed with manpower, and being easy to put together and cut, they contribute to increased efficiency at the work site.
