Product Operate Guide

1. Check the product status

Before use, confirm that the chicken heart ring has no cracks, deformation, or severe rust, and that the surface coating is intact. Check if the specifications of the steel wire rope match, ensuring that there are no issues such as broken wires or excessive wear.

2. Install the steel wire rope correctly

Thread the end of the steel wire rope into the chicken heart ring, bend it into a circular shape, and fix it with a rope clamp or compression sleeve. Ensure that the reserved length of the rope head is ≥ 3 times the diameter of the steel wire rope, and the spacing between the rope clamps is ≥ 6 times the diameter of the rope and evenly locked.

Q1. What is a Wire Rope Thimble?

A: Wire Rope Thimble is a metal ring accessory, usually made of stainless steel, carbon steel or galvanized steel, with a shape similar to a chicken heart (one end is arc-shaped, and the other end is an open or closed ring). Mainly used for end protection of steel wire ropes, cables or ropes, to prevent wear or loose strands, and to enhance the load-bearing capacity of connections.

Q2.What is the purpose of a Wire Rope Thimble?

A: Protect steel wire rope/rope: Cover the rope end to prevent wear, deformation, or loose threads.

Enhanced connection: Used in conjunction with clamps (such as wire rope clamps, shackles) to distribute stress.

Guiding function: Used in equipment such as pulleys and hooks to reduce friction.

Common application scenarios: lifting operations, ship mooring, power lines, outdoor cables, etc.

Q3.What are the types of heart rings?

A: Open type Wire Rope Thimble: One end is open for easy installation and needs to be fixed with a clamp.

Closed type Wire Rope Thimble: It is completely closed and has higher strength, but requires pre threading of a rope.

Galvanized/stainless steel Wire Rope Thimble: rust resistant, suitable for outdoor or humid environments.

Q4. How to install a Wire Rope Thimble?

A: Thread rope: Insert the end of the steel wire rope into the heart-shaped ring, leaving enough length.

Fixed: Use a wire rope clamp (U-shaped clamp) to press the rope end tightly, usually using at least 2-3 clamps.

Inspection: Ensure that the clamp nut is tightened and the rope end bending length is ≥ 6 times the diameter of the steel wire rope.

Q5: Can a Wire Rope Thimble be welded?

A: Welding is not recommended as high temperatures may alter metal properties and affect strength.

Q6: Can Wire Rope Thimbles be used for lifting human bodies?

A: Strictly prohibited for personnel lifting, only for cargo lifting.

Q7: How to distinguish inferior Wire Rope Thimbles?

A: Check if the surface is smooth and free of burrs, the material is uniform, and labeled with specifications and manufacturer information.
