US 6,578,825 B1 · Wire rope equalizer system for hoist mechanisms

Abstract

A wire rope equalizer system for a conventional double reeved hoist mechanism using wire rope is disclosed. The wire rope equalizer system includes a base member that is secured to the hoist mechanism for selective rotation and a pivoting lever that is pivotally connected to the base member. The pivoting member includes mounting extensions each having a mounting aperture therethrough that receives a ball shank that is secured to a distal end of the wire rope. Each mounting aperture has a grooved section that cooperates with the rounded end of the ball shank to permit rotational movement of the wire rope in a no load condition. Each mounting aperture further includes a conical section that flares outwardly in a lateral direction to permit selective lateral movement of the wire rope to counteract wire rope twist in a no load condition. An alternative embodiment for a single reeving hoist mechanism is also disclosed.

Dependent claims

A wire rope equalizer system for a conventional hoist mechanism, comprising:

a base member mounted on the hoist mechanism for selective pivotal movement, said base member having at least one attachment arm;
a lever member having at least one attachment lip that cooperate with said attachment arm to pivotally connect said lever member with said base member;
wherein said lever member further includes mounting extensions positioned on opposite sides of said attachment lip,
said mounting extensions having mounting apertures formed therethrough, said mounting apertures adapted to received distal ends of a wire rope such that said wire rope is free to rotate to counteract wire rope twist in a no load condition.
