Multi pulley control gate
A control gate adapted to be installed across a channel for liquids, the control gate comprising a barrier member with a side member or offset member that has a circular arcuate section, said barrier member being pivotally mounted at or adjacent to the base of said channel; and a drive for raising and lowering said barrier member to regulate flow of liquid through said control gate, said drive including a cable, motor and first and second pulleys, said first pulley coupled to said motor, said cable secured to opposite first and second ends of said circular arcuate section under tension with said second pulley being adjacent to said circular arcuate section, said cable passing along said circular arcuate section from said one end to pass under said second pulley in contact therewith, said cable then being looped under tension at least once around said first pulley located above said second pulley, said cable then passing under said second pulley in contact with the opposite face of said second pulley to be secured to said second end of said arcuate section in order to maintain said cable in a substantially peripheral contact with said circular arcuate section, said second pulley transferring rotary motion of said first pulley into motion of said side member or offset member to movement of said barrier member to regulate flow of water through said control gate.
