Rack-type opening and closing mechanism for river facility sluice gates contributes to reduced maintenance, space-saving, and cost reduction.
Easy Operation There is no need to switch between electric and manual modes. By eliminating the switching device, the interlock circuit that was previously necessary is also no longer required. Contributes to Energy Saving The main reduction gear uses a helical gear system like conventional models, ensuring high efficiency with no wasted energy. Comprehensive Safety Devices The following safety devices are included: - Overload detection device that operates in both electric and manual modes - Upper and lower limit restriction devices - Emergency upper limit detection device - 1m rack rod cover Additionally, it features a mechanical self-locking mechanism with a mechanical brake, enhancing absolute safety. Equipped with Self-Weight Drop Function With just lever operation, the door can descend under its own weight without using driving power. Remote operation is also possible (optional). Rich Features We offer a wide range of models, including electric single-action types (20–125kN, 8 models) and electric linked types (30–1000kN, 16 types). (Models over 315kN come with a lubrication device.)

Company information
In November 1950, we were established to inherit the business of the former Special Gear Manufacturing Co., which had been active in the industry as a gear reducer manufacturer since the early Showa period, and to manufacture various types of gear reducers and paddle wheel ash removal devices. Since our establishment, thanks to the support of our customers, our business has steadily developed, and we have completed several capital increases. In May 1973, we built a new factory in Shingo, Hyogo Prefecture (now Tamba City), enhancing our production system in the gear reducer division while also developing unique new products in the labor-saving machinery division. In recent years, we have been manufacturing various drive devices for water treatment, aqua aerators, as well as various gear reducers and small opening and closing devices for gates in rivers and dams, and we continue to this day.
