Exhibiting at the Construction and Surveying Productivity Improvement Exhibition CSPI-EXPO starting this Wednesday - Sain Japan Co., Ltd.

Automatic coupling for hydraulic attachments for construction machinery, demolition, and agricultural machinery.

By incorporating the ADX coupling into the automatic attachment multi-plate of a mobile hydraulic attachment, operators can safely and easily change attachments without getting out of the vehicle. ● Easy and correct connection: large core runout tolerance ● Ideal for demolition and construction sites: durability against high surge flow ● Flexible attachment to the automatic attachment multi-plate ● Minimizes oil leakage: flat face design ● Connection and separation possible under pressure

• Drilling Machine

Introducing a completely improved new model! Simultaneous connection of multiple hydraulic ports. A groundbreaking connection system that changes the system design of hydraulic equipment.

Multi-X connects up to 6 hydraulic circuits simultaneously. The ergonomically designed operability allows for quick and easy connection of multiple circuits, preventing incorrect port connections. ● Easy connection with lever operation (with safety lock mechanism) ● Simultaneous connection of up to 6 ports ● Flat face design that prevents liquid leakage during attachment and detachment, making cleaning easy ● Prevents air and foreign matter contamination ● Built-in nipple with a residual pressure removal mechanism that allows for connection under pressure ● Ports available in three sizes (3/8", 1/2", 3/4") ● Maximum operating pressure of 35MPa (system total 80MPa) ● Features CEJN's unique plug-in hose connection Check out the details of Multi-X GII in the video! https://www.cejn.com/ja-jp/products/hydraulics/multi-x-range/

Reduce troubles during boom and arm replacement! Efficiently and cleanly disassemble and assemble large demolition machines and high-altitude demolition machines!

High surge flow (rapid changes in flow rate) is the most common reason for screw-type couplings to fail in harsh applications. Previous solutions involved using oversized couplings that were expensive and bulky. However, that is no longer necessary. The TLX flat-face twist-lock quick-connect coupling is designed to handle the highest surge flows and pressure fluctuations. A new 3/8" model (TLX 307) is now available. Made of high-alloy steel and coated with zinc-nickel plating, it ensures long life even under severe conditions. Sizes range from 3/8" to 1 1/2", making it suitable for most applications.

• Foundation construction machinery

Prevents liquid leakage during attachment and detachment! Environmentally friendly flat face coupling for hydraulic equipment.

The "X65" features a flat face design that prevents liquid leakage during connection and disconnection, protecting the surrounding environment from contamination. It also allows for easy removal of contaminants from the connection surface, preventing foreign matter from entering the hydraulic circuit and maintaining equipment performance. ● Flat face design with no liquid leakage during attachment and detachment, making cleaning easy ● Prevents air and foreign matter from entering the hydraulic circuit ● One-touch connection by simply pushing in the nipple ● High flow rate and high durability design ● Standard safety lock mechanism to prevent unexpected disconnection ● Compliant with ISO16028 ● Available in 7 sizes (1/8" to 1")

Achieving connections under pressure! Flat face nipple for hydraulic equipment with residual pressure removal mechanism.

The X64 series is a flat face nipple with a built-in residual pressure removal mechanism. It enables one-touch connection under pressure without the use of special tools. Please choose the corresponding "X65" flat face coupling.

• Rock drills, demolition machines, and excavators

Compliant with the world standard ISO 15171-2 for pressure testing systems. Compatible with pressure testing systems of the same standard, making it easy to check pressure!

The press check is designed and manufactured based on the world standard ISO 15171-2 for hydraulic systems, ensuring compatibility with products from other manufacturers that meet the same standard. It can be installed anywhere that requires pressure testing in hydraulic systems. ● Screw connect type pressure testing system ● Maximum operating pressure 63MPa ● Various thread standards and sizes ● Made of high alloy steel (plated) for corrosion resistance

• others

Make pressure testing of hydraulic systems simpler! The unique pressure testing system from Sain reduces the time and space required for pressure testing.

The snap-check system is designed for pressure measurement in hydraulic systems. By simply combining a hydraulic gauge with Seino's uniquely designed coupling and nipple, a one-touch pressure testing system can be realized. This reduces the time required for pressure testing and minimizes the workspace needed for testing operations. ● Easy pressure testing with one-touch connection ● Maximum operating pressure of 60MPa ● One-touch connection possible under pressure (up to 30MPa) ● Highly flexible hose kit that simplifies measurement tasks in high or narrow locations ● Various thread standards and sizes

There are many programs available for management training, leadership training, and so on. This indicates that the needs of various companies are diverse, and the forms of solutions also differ. Our company regularly holds experiential seminars aimed at those responsible for or researching leadership training within each company, allowing them to experience the essence of management games. Please consider this as a solution for organizational challenges. The benefits of the experiential seminar are as follows: • You can experience the intrinsic value of management games. • You will understand the core of experiential training that cannot be conveyed through catalogs, brochures, or websites alone. • You can envision which programs should be applied to which job levels. • You can imagine the degree of growth of your employees after participating in the training. *This is aimed at those responsible for corporate education and training. Individuals seeking learning for personal purposes should participate in public seminars. [Request when applying] Please specify "via the Ipros site" when asked how you learned about our company.

Finally, the practical use of generative AI in the construction industry has been advancing. By utilizing generative AI, the operations in the construction industry have significantly improved, and many case studies have emerged. On the other hand, it is challenging to experiment with various tools, and there are not many courses specifically tailored for the construction industry. In this training, over two days, you will intensively learn generative AI practical skills specialized for construction, which you can immediately apply on-site starting the next day. This "super practical program" will allow you to quickly acquire skills to automate and streamline the creation of construction plans and presentation materials by utilizing the latest generative AI tools available for free, from the basic mechanisms of AI. It goes beyond mere technical introduction, enabling you to gain know-how that can be immediately used on-site through practical exercises directly related to your own work.

The Hokkaido Chamber of Commerce and Industry will hold an "Employee Skill Improvement Seminar" aimed at enhancing the skills of employees engaged in the construction industry and contributing to the stability of management. This seminar is recognized as a CPDS accredited training by the National Association of Civil Engineering Construction Management Engineers, and participants can earn 10 units by attending all lectures over the two days. Since this seminar is eligible for our subsidies, we encourage you to consider active participation.
