ABSTRACT:
A counterweight link rod incorporates a counterweight lifting lug to provide a safe and easily usable means to lift a counterweight during erection or maintenance for positioning it with respect to a connection point with the wicket gate operating ring. The arrangement also provides a readily available permanent means for attaching an overhead crane hook to the wicket gate operating ring for stroking the gates during erection or maintenance. The arrangement also provides a means for operating the wicket gate operating ring when the operating ring servo-motors fail.
