| R Type-Next Generation Low-cost, High-quality Onsite Clamping Joint Capable of Replacing Pressure Welding for New Constructions and even for Reinforcement or Expansion Projects for Existing Structures
The R Type is a low-cost, high-quality onsite clamping joint best suited for the reinforcement or expansion of existing structures. Onsite clamping work with the R Type is simple, which can significantly improve work efficiency. Installation work uses a hydraulic pump and pressure bonding machine. The hydraulic pump has casters ensuring ample mobility onsite, while the pressure bonding machine specially developed for job site work is easy to operate and does not require trained and specialist workers. In addition, another advantage of the R Type is that installation work is not affected by rain. The R Type coupler is easy to install onsite and also cleared the Stand-alone Performance Class SA rating of the Japan Society of Civil Engineering, making it a next generation, low-cost, high-quality coupler fully capable of replacing pressure welding. |
