Technology

Our group responds to diversified needs of construction machinery by always making full use of cutting-edge technology from design to product development.

We respond to a wide range of customer needs flexibly and provide products with the best quality, cost and delivery, based on our uniquely accumulated development, production technology, and supply capabilities.

Development ability to create product quality from the initial design stage

When designing suspension parts, we not only evaluate individual parts, but also conduct evaluations that consider the behavior of the entire construction machine using CAE. The vast amount of data we have accumulated and the products that we create through our consistent process from design to manufacturing have earned the tremendous trust of many construction machinery manufacturers.

Overwhelming production technology capabilities unrivaled by other companies

We are building quality and cost reduction that other companies cannot imitate with our unique heat treatment technologies and equipment that embodies it. For heat treatment technologies, in particular, we optimize manufacturing conditions and build in quality at the design stage using our proprietary heat conduction analysis system. In addition, we have developed the world's fastest link processing line and an automatic assembly line for link belt that cannot be found in other companies, to supply track with stable quality and low cost to the world.

Ability to supply everything from material selection to product supply

track shoe, the main product of our group, are produced within our group from the selection of materials to the completion of products through close collaboration between our Steel Division manufactures and rolls steel, and Undercarriage Components Division. We also have a high-speed link processing line that boasts high productivity. Through integrated production and highly productive facility capacity, we maintain a supply capacity that allows us to flexibly respond to the demands of our customers who are expanding globally.
