Industrial / Construction machinery


While challenging the automated equipment for refrigerating machines,
Konan succeeded manufacturing of pneumatic equipment for domestic production of spot welding machine at the end of trial and error for the first time in Japan in 1941.
At the time of development, the pneumatic technology itself was not perceived at all.
Data and theory supported by steady research and development by Konan's technical team have become the cornerstone of Japan's pneumatic technology after all, even though there is no logical academic material.
We started production of hydraulic breakers, which are attachments for hydraulic excavators In 1973.
Based on experience and know-how accumulated over many years, Konan always creates new value by continuing to challenge technological innovation.
