  • Patent number: 11739487
    Abstract: A configurable modular dam gate hoist system is disclosed. The dam gate hoist system includes a first hoist support frame, second hoist support frame, first side segment with a first adjustable hoist drum, second side segment with a second adjustable hoist drum, a hoist drive assembly, and optionally a middle segment. The middle segment, when utilized, is constructed of pre-made components with set lengths in the factory, with the length of the middle segment being varied by using components with different set lengths. Both the first and second side segments include an adjustment slot or keyway that receives adjustment bolts (preferably including standard square keys) of the first and second adjustable hoist drum to allow the position of the drums to be adjusted and secured in the desired location on the tube to correspond with the desired fleet angle of the gate chain, cable, or wire rope.
