ABSTRACT
Tainter gates (radial gates) are frequently used as a crest gate of dam for a flood release. In the type of Tainter gates, as the resultant of the hydraulic pres sure exerted on the skinplate generally passes near the trunnion pin and is nearly borne at the trunnion pin as shown in Figure 1, the effect of mechanical friction in Tainter gates is much less than in the other type of gate, such as vertical lift gates, therefore providing a small hoisting load and a smooth operation of the gate. Hence the Tainter gate is suited for the larger sizes.
