Tainter (Radial) Gates consist of a curved skinplate reinforced by horizontal or vertical stiffening ribs and supported by radial arms on each side of the gate. Tainter gates are commonly used for flood control on spillways where vertical lift gates are impractical. The operating machinery is located above the tainter gate and typically includes wire rope hoists, chain or drum hoists, or hydraulic cylinders to allow for full travel with minimal overhead super structure.
