Thimble Mechanism For Retention Of A Shackle In A Wire Loop Termination

A method of retention of a shackle in a wire rope loop termination wherein said shackle includes a bow and a pair of opposed legs with each of said legs having an end with a width smaller than a depth, which method comprises:

• inserting a bow of said shackle into a central opening of a thimble body by passing through a keyway in said thimble body extending from said central opening to an external arcuate edge of said thimble body;
• receiving a wire rope around a rope groove in said external arcuate edge of said thimble body;
• and
• forming a wire rope loop termination in order to close said keyway with said wire rope.

A thimble assembly for a wire rope loop termination for retention of a shackle having a pair of opposed legs, which assembly comprises:

• a thimble body having an external arcuate edge with a rope groove for receipt of a wire rope therein;
• a central opening through said thimble body for receipt of said shackle;
• a retaining pin;
• and
• a pair of openings in said thimble body to receive said retaining pin across said central opening.

A method of retention of a shackle in a wire rope loop termination wherein said shackle includes a bow and a pair of opposed legs with a defined space between said legs, which method comprises:

• inserting a shackle through a central opening in a thimble body;
• receiving a wire rope around a rope groove in an external arcuate edge of said thimble body;
• completing said wire rope loop termination;
• and
• preventing said shackle from being removed from said central opening in said thimble body.
