The "Rubber Dam" is a rubber weir that has a simpler civil structure compared to other gates, making maintenance easy and maintenance-free. It enables low-cost, high-performance flood control and water utilization. Since the rubber is inflated with compressed air, there is no need for equipment such as hydraulic cylinders, eliminating concerns about oil leaks into the river. Nihon Jidoki Kogyo Co., Ltd. constructed its first rubber-coated fabric weir in 1964 and has continued to install this product at over 530 locations. 【Features】 ■ Can accommodate various river cross-sections and bank slopes ■ Installable in various sizes, from small sizes to long sizes near estuaries ■ Design can be tailored to river conditions and intended use *For more details, please refer to the PDF materials or feel free to contact us.

• Watergate

We would like to introduce the pump gate handled by Nippon Automatiki Co., Ltd. In a typical drainage facility, a separate space for the facility was required apart from the natural drainage channel. With this product, by integrating the gate and pump and installing it within the natural drainage channel, we achieve a compact drainage system at a reduced cost. 【Features】 ■Cost-effective - The land required for the drainage facility is significantly reduced - The configuration of the facility is simplified, resulting in smaller civil structures ■Simplification - The equipment is installed over the natural drainage channel, making it significantly smaller than conventional types - The equipment configuration is streamlined, making operation and maintenance easier *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the spillway that is handled by Nippon Automatic Machinery Co., Ltd. It is designed to pivot around a hinge located at the bottom of the door body, and since there are no tall structures like roller gates, it is more economical and aesthetically pleasing than long-span roller gates. There are two types available: the torque axis type with a hydraulic cylinder inside the side wall, and the rear push-up type with the hydraulic cylinder located at the back of the gate. 【Features】 ■ Pivots around a hinge located at the bottom of the door body ■ No tall structures like roller gates ■ More economical than long-span roller gates ■ Excellent aesthetics ■ Available in two types: torque axis type and rear push-up type * For more details, please refer to the PDF materials or feel free to contact us.

This product is a gate without gateposts that considers the landscape, unlike conventional lift gates. We offer a lineup of "power flap gates" that drive the flap using hydraulic cylinders, and "expansion gates" that seal the pipe with an air-inflated rubber bag (rubber gates for pipelines). The expansion gate comes in two types: one designed to be installed in concrete culverts and another that is installed with the entire casing. 【Power Flap Gate Features】 ■ Eliminates the shortcomings of commercially available flap gates ■ Responds to reverse water pressure ■ Does not obstruct water flow ■ Opens and closes using hydraulic cylinders *For more details, please refer to the PDF materials or feel free to contact us.

The "Roller Gate (Wire Rope Winch Type)" is a beam-structured gate that has rollers (wheels) at the ends of the door body, which reduces the resistance encountered when moving the door body due to the rotation of the rollers. One of its features is that it has a smaller opening and closing load compared to slide gates. 【Features】 ■ Reduces resistance when moving the door body ■ Smaller opening and closing load compared to slide gates *For more details, please download the PDF or feel free to contact us.
