ABSTRACT:
Illustrative embodiments of the invention are directed to a technique for raising and lowering large tainter gates. Typically, two groups of lifting apertures are formed in the gate. A lifting mechanism, resiliently mounted on the tainter gate pier, inserts a movable pin into an aperture in one of the two groups and draws the gate upwardly. A stationary pin on the lifting mechanism then is inserted into an aperture in the other of the two groups to absorb the gate load while the movable pin is withdrawn and moved to a new aperture in order to continue the step-wise lifting process.
To lower a gate, an essentially reverse procedure is followed.
