【Product PR】 The "MS Method (Mechanical Stitch)" is a groundbreaking repair technique (Mechanical Stitching Method) that uses mechanical methods to address cracks in metal. Since it does not apply any heat, there is no "thermal distortion." It prevents residual stress from occurring in other areas and avoids secondary damage such as new cracks. Cracks in metal are one of the concerns in equipment maintenance operations. In typical welding repair methods, the base material around the crack changes due to heat, leading to residual stress and distortion, which always carries the risk of "crack recurrence" and "secondary damage." 【Features of the MS Method】 ■ No hardening or residual stress due to heat ■ Elimination of secondary damage ■ Maintenance of stable quality → Integrated system repairs using jigs, etc. → Accumulation of know-how, experience, and achievements ■ Completion of construction in a short period → No significant decrease in equipment operating rates ■ Advantages in safety and environmental aspects → No use of fire, so there is no impact on the operating rates of other equipment or the environment For more details, please contact us.

For work in dark places! Easy to move, simple to set up, introducing examples of instant bright balloon-type floodlights.

There is also a type that can be mounted on carts equipped with batteries or generators, making it useful even in locations without power. [Challenges] ■ Want to illuminate a wide area brightly in 360 degrees ■ Heavy items are difficult to transport ■ Want to make maintenance easier *For more details, please refer to the PDF document or feel free to contact us.

Easy to move, simple to set up, and instantly bright! It can illuminate 360 degrees with a bright light that is gentle on the eyes!

We would like to introduce a case where the balloon-type floodlight "Max Moon" was implemented at construction, firefighting, and disaster sites.

It is lightweight, making it easy to carry, and it can be easily opened and folded.

Hex wrench stand

Make hex wrenches easier to use! You can instantly tell whether the hex wrench in the size you want is there or not.

We handle the "Hex Wrench Stand." It is compact as it stands upright. The entrance of the holes is angled for easy visibility and insertion. Since the holes are connected (through holes), the wrenches slide in smoothly without getting stuck halfway. Unlike the sheet metal type, they do not stop midway. The material is made of steel, and the surface is chrome-plated to resist rust. 【Features】 - The entrance of the holes is angled for easy visibility and insertion. - The connected holes (through holes) allow for smooth insertion without getting stuck. - Made of steel with a chrome-plated surface that is resistant to rust. - Can be easily rotated with a finger to avoid interference. - Sizes are clearly displayed, making it easy to see whether the desired size of hex wrench is available at a glance. *For more details, please refer to the PDF document or feel free to contact us.
