ドゥ・ヤマモト Company Profile

In Japan's manufacturing and construction sites, measures against the breakage and detachment of hydraulic hoses are required by JIS B 6711. However, are we fully prepared for the "whip effect," which can cause violent movements when hoses are damaged or detached? In response to this risk, which can lead to personal injuries and equipment damage, Du Yamamoto, as a specialized trading company, points out the most critical issues on-site and emphasizes the necessity of reliable safety solutions. We will explain the dangers of the whip effect and the importance of compliance with JIS standards.

We have started domestic stock sales of the safety wire "STOPFLEX," which protects lives and equipment from the whip effect of high-pressure hoses. It can handle up to 45 MPa and has a simple structure that allows for easy retrofitting to existing equipment. With the start of stock sales, we can now quickly supply sites that require urgent safety measures. As a specialized trading company for hydraulic hoses, we provide one-stop support from optimal hose selection to the supply of safety measure components.

Du Yamamoto also handles WHIP CHEK for air (compressed air) hoses, in addition to STOPFLEX for hydraulic hoses. We can propose optimal safety solutions tailored to fluids and environments in a one-stop manner. With our high technical capabilities as a Bridgestone certified factory, top-class domestic inventory, and rapid assembly capabilities at our own factory, we strongly support the continuity of our customers' businesses.
