Construction machinery and agricultural machinery such as power shovels, cranes, etc transmit their power by hydraulic hoses. One power shovel has about 120 joints used for these hydraulic hoses. We manufacture the joints for high-pressure piping used for power shovels and other machinery. These joints and fittings for machinery must be extremely durable enough to resist high inner pressure up to 200 to 400 kilograms per one square centimeter to prevent accidents or breakdown. To meet these tough conditions, we have developed and manufactured joints and fittings with stable quality applying our high technology of manufacturing products with reliable quality to resist harsh environment.

パワーショベルやクレーンなどの建設機や農業機械などは、油圧ホースによって動力を伝達します。１台のパワーショベルの油圧ホースには約120個の継ぎ手がありますが、そこに当社の高圧配管用継ぎ手が使われています。機械の継ぎ手は、事故や故障を未然に防ぐため１平方センチメートルあたり200〜400Kgの高い内圧に耐えることが要求されるため、確かな品質と過酷な環境に耐えうる高度な製造技術をもって、安定した品質を実現しています。
