Chapter 6

What are the shackles parts?

Shackles, essential in lifting and rigging, typically consist of the following parts:

  1. Shackle Body: The main component, usually U-shaped or bow-shaped, is designed to bear the load. It’s the part through which the lifting medium (like a rope, chain, or sling) is attached.
  2. Pin: This is the securing element that passes through the holes at the ends of the shackle body. The pin can be of different types, such as a screw pin, a bolt-type pin, or a round pin, each suited for specific applications.
  3. Threaded Section: Found in screw pin shackles, this section on the pin allows for secure screwing into the shackle body, making it easy to attach and detach.
  4. Bolt and Nut (in Bolt-Type Shackles): Some shackles use a bolt and nut mechanism instead of a screw pin. This setup is often more secure and used in permanent or semi-permanent applications.
  5. Cotter Pin (in Bolt-Type and Round Pin Shackles): A small pin or clip used to prevent the bolt or round pin from loosening or accidentally coming out during use.
  6. Shoulder (in Some Designs): The area where the shackle body curves to meet the pin holes. In some designs, the shoulder is reinforced to handle additional load stress.

5. Maintenance and Longevity:

    • Galvanized Steel: This may require maintenance if the zinc layer is damaged. Its lifespan can be shorter in extremely corrosive environments.
    • Stainless Steel: Low maintenance due to its corrosion resistance and does not require additional coating. It often has a longer lifespan in corrosive environments.

In summary, the choice between galvanized and stainless steel finishes depends on factors like specific environmental conditions, required strength, budget constraints, and longevity expectations. For rigorous, high-corrosion settings, stainless steel is usually the preferred choice, whereas galvanized steel is often selected for general outdoor or industrial applications where high durability and cost-effectiveness are key considerations.
