Abstract

See full text

An automatic rope tension equalizer system includes first, second, and third plungers, first, second, and third cam assemblies, and a hitch plate with first, second, and third cavities. The first, second, and third plungers are at least partially situated in the first, second, and third cavities, respectively. Each cam assembly has a cam and a rod extending therefrom. The cam of the first cam assembly engages the first plunger, the cam of the second cam assembly engages the second plunger, and the cam of the third cam assembly engages the third plunger. A network connects each cavity to each other cavity, and fluid in the network automatically equalizes pressure on the first, second, and third plungers, thereby affecting positioning of the first, second, and third plungers and, through each cam, tension on each rod.
