Quick Summary
A rolling gate, also known as a roller gate, is a type of movable barrier used in hydraulic engineering to control the flow of water. These gates are often found at the crest of a dam.1
A rolling gate functions as a hollow drum positioned horizontally. It is raised or lowered along an inclined track by a system of pinions and racks, allowing for the regulation of water elevation. This mechanism enables precise control over water outflow from reservoirs and through or around dams.21
