We will introduce examples of truck loading. Each unit has been significantly miniaturized compared to conventional products to reflect the actual construction environment, allowing all equipment, including the generator, to fit into a single 2-4 ton truck, making it easy to use in a wide range of sites. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce the "Paint Stripping Device (Prototype Model)" designed for paint stripping work on steel bridges in narrow spaces such as scaffolding. With temperature control using a non-contact sensor, heating can be stopped at a user-defined temperature, preventing overheating. Additionally, we offer optional heating coils for corners and bolts that can accommodate fine uneven surfaces. 【Features】 ■ Heating ON/OFF via a hand switch for the heating coil ■ Temperature control using a non-contact sensor ■ Monitoring of cooling water flow rate and temperature ■ Timer function for heating duration ■ Heating coils for corners and bolts (optional) *For more details, please refer to the PDF document or feel free to contact us.

Induction heating for paint stripping efficiently removes only the paint film, resulting in waste that consists solely of the paint film. Scaffolding and protective equipment are sufficient at the level of standard paint scaffolding. Furthermore, the generation of dust containing heavy metals is suppressed during work, and there is no noise produced from the heating coils or power supply. 【Features】 ■ Reduction of waste generation ■ Improvement of the working environment ■ Consideration for the surrounding environment *For more details, please refer to the PDF document or feel free to contact us.

Conventional paint stripping has several challenges. However, paint stripping using induction heating offers advantages such as rapid heating and easy temperature control. 【Challenges of Paint Stripping】 ■ Conventional methods like blasting and scraping generate large amounts of dust and abrasives, along with noise during operation. ■ If the paint contains harmful substances, the waste disposal becomes substantial. ■ Strippers soften the paint through chemical reactions, making them highly susceptible to weather and environmental temperature changes. *For more details, please refer to the PDF document or feel free to contact us.*

• Special Construction Method

Induction heating is a technology that generates a magnetic field by passing a large current through a coil, inducing eddy currents on the surface of the steel, and heating the steel itself through the Joule heat generated by the induced eddy currents. It has features such as the ability to easily heat only the necessary parts locally. 【Features】 ■ Rapid heating is possible, and temperature control is easy ■ Non-contact heating that does not damage the material surface ■ Easily allows for localized heating of only the necessary parts *For more details, please refer to the PDF document or feel free to contact us.

Introducing "Induction Heating Paint Stripping." Induction heating is a technology that generates a magnetic field by passing a large electric current through a coil, inducing eddy currents on the surface of steel materials, and heating the steel itself through the Joule heat generated by these eddy currents. By using a high-frequency power supply, it is possible to heat the very surface of the steel material. The "IH (Induction Heating) Paint Stripping Device" applies this principle by directly heating the surface of the steel plate from above the paint, reducing the adhesion of the paint film and facilitating its removal. **Features of Paint Stripping by Induction Heating:** - Reduction of waste generation - Improvement of the working environment - Consideration for the surrounding environment *For more details, please refer to the PDF document or feel free to contact us.*

• Special Construction Method

Our company offers the paint stripping method "IH Method," which allows for easy and clean removal of paint films that have become loose due to heating by scraping them off with a scraper. This method is environmentally friendly and enables the quick removal of old paint films. It has already been trialed on the Kanmon Expressway Kanmon Bridge and has received high praise as a new technology and method that improves workability. 【Features】 ■ Reduction of waste generation ■ Improvement of the working environment ■ Consideration for the surrounding environment *For more details, please download the PDF or feel free to contact us.
