Powerfully Supporting Excavation, Construction, and Mining All Over the World
Infrastructure development and the mining of resources are sometimes done under particularly challenging conditions, such as in wild desert country, on steep slopes, in a jungle, or under the sea (such as in pipeline construction). To complete such work, powerful and high-precision construction machinery is essential.
Nabtesco contributes to improving the performance of such machinery with its hydraulic technology, which helps draw tremendous power from small units. Specifically, we provide traveling units for hydraulic excavators and control valves for various actuators, among others.
This is how we support work on construction sites around the world while at the same time taking on the challenge of developing new hydraulic technologies as an industry leader.
When it comes to traveling units for hydraulic excavators, our global market share is approximately 25% (Nabtesco’s estimate).
Social Value Provided by the Business
- We are building the foundation for further industrial development and supporting everyday life by providing products for use in construction machinery that plays an essential role in building physical infrastructure.
- We also contribute to the development of local industries by manufacturing our products in regions where there is demand for them.
Traveling Unit for Crawlers
This series is used as a traveling unit for crawlers and the wheels of excavators, crawler drills, crawler cranes, crawlers for aerial work platforms.
Control Valve for Mini Excavators
This product is a sectional-type multi-control valve developed specially for mini excavators, and is ideal for various needs such as action control of excavators. The series is popular for its compact size, versatility, and strong lineup. It has captured a large market share in Japan.
Swing Unit for Hydraulic Excavators
The swing unit used in hydraulic excavators consists of a high-speed motor and planetary reduction gear unit. Its compact design allows the unit to have fewer components and operate very quietly. In addition to units for hydraulic excavators, swing units are also used in small-sized cranes and winch motors for aerial working platforms.
