WebTainter gates that are held in place by post tensioned anchor rods. A large percentage of the anchoring systems employed, including many that utilize smooth anchor rods, require periodic testing to insure the rods still contain the tension force intended by the designer and needed to provide the appropriate factor of safety against future loads. Webextend back to the trunnion. Each arm acts as a column in transmitting the load from the gate leaf to the trunnion. The radial arms are angled toward the center of the gate intersecting the horizontal supports at a point approximately one-sixth of the way in from each side. This reduces gate deflection, the weight of horizontal
