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.

The hose selection platform "Hose Search Dot Com," operated by our company, is rapidly gaining popularity as an educational tool that supports the development of young talent and the transmission of technology, particularly in the manufacturing and construction industries! With the retirement of the baby boomer generation progressing, the reliance on OJT (On-the-Job Training) for passing down hose selection knowledge has become a serious issue. Traditional training methods depend on unstructured information and the experience of veterans, resulting in new employees taking a long time to become productive, which increases training costs. "Hose Search Dot Com" digitally addresses these on-site challenges. It features a hose search function that condenses our company's accumulated knowledge since its founding! Fully optimized for PCs and smartphones, it allows new employee training and young engineers to make correct selections based on hose types, materials, and standards while actively working on-site. Companies that have implemented it report clear benefits, such as "a 30% average reduction in training time" and "a decrease in knowledge level variability, which has also reduced the risk of product-related issues."

Our service "Hose Search Dot Com" is a groundbreaking platform that systematizes professional knowledge related to hose selection and maintenance, making it applicable for industry-specific education. Selecting hoses on-site is a crucial task directly linked to safety and durability, but the transmission of knowledge necessary to assess material, pressure resistance, and the compatibility of complex fittings has been a significant challenge. This service allows users to find hoses based on a single search criterion. It is structured to focus on the "immediate need" for hose selection information, based on the expertise of our industrial hose specialists. The most notable feature is its powerful search function that can be accessed via PC or smartphone, moving away from bulky catalogs. Young engineers can access it on their smartphones while working on-site, allowing them to resolve questions in real-time. This helps prevent variations in knowledge levels due to differences in experience, contributing to the standardization of work quality and the reduction of accident risks. We continuously add the latest information and provide it as a "living teaching material," supporting the enhancement of user companies' competitiveness.

Our company proposes a groundbreaking BCP solution called "Emergency Recovery Completed In-House." Our "Immediate Delivery Assembly" system, "Universal Hose," and "On-Site Fitting Installation" capability make a "No Preparation BCP" that achieves both cost reduction and rapid recovery a reality. The FC300 allows for the on-site installation of AMR (Reusable Fittings), and the FC332 allows for the on-site installation of LAR (Reusable Fittings). As long as you have the hose and corresponding fittings on hand, you can complete the hose assembly in-house and quickly finalize repairs. This minimizes production line downtime and provides a significant advantage in business continuity. Powerful Support: The "Immediate Delivery Assembly" system from Do Yamamoto maximizes the potential of the versatile hose and on-site repair capabilities. With top-level domestic inventory and high-quality assembly technology backed by years of experience, we can quickly process and deliver even a single unit in emergencies, strongly supporting our customers' business continuity. This combination of "Universal Hose," "Immediate Delivery System," and "On-Site Repair Capability" transforms traditional "Diverse Inventory" into a "No Preparation BCP," achieving both cost reduction and robust business continuity.

Do Yamamoto Co., Ltd. will introduce another contribution to BCP provided by Eaton's "Aeroquip (AQP) Hose," following the previous topic of "versatility." This contribution addresses the "heat generation issue of the hose itself in high-temperature environments" and "superior durability." This strongly supports the safety and stable operation of industrial sites. In recent years, with the advancement of industrial machinery, the use of hoses in high-temperature environments has increased. Conventional flexible hoses tend to overheat when high-temperature fluids flow through them, leading to risks of burns, impacts on surrounding equipment, and premature deterioration of the hoses. The AQP hose boasts high heat resistance and durability that solve these issues. The AQP hose features excellent heat resistance, rated for a maximum of +150°C both internally and externally, which suppresses the rise in surface temperature of the hose. Its proven performance of showing no impact on the cover even after being exposed to a +150°C environment for 1000 hours demonstrates its safety and stable operation. Furthermore, it possesses high durability that passes over one million impulse tests, along with resistance to oxidation, ozone, and chemicals, reducing the risk of sudden failure and strengthening BCP.
