Do’s & Dont’s With Lifting Shackles

Shackles come in many types and may be used in various rigging and load securement applications. However, as with all equipment, certain guidelines must be followed to ensure lifting shackle safety during operations!

What are lifting shackles?

Lifting shackles are metal, U-shaped components commonly used in lifting operations. They serve as a secure connector between a lifting sling, hoist hook, or other rigging equipment and the load being lifted. Acting as the final link in the lifting chain, shackles are designed to open and close easily, allowing quick attachment or detachment of the load as needed.

Key Features and Uses of Lifting Shackles:

  • Function:
    Lifting shackles provide a strong, reliable point of attachment between a lifting sling and the object being lifted, ensuring safe load handling.
  • Design:
    Typically, a shackle features a bow-shaped body and a removable pin. The pin fits through the ears of the shackle to securely fasten the load in place.
  • Types of Shackles:
    Shackles come in various designs tailored to specific needs, including:

    • Screw Pin Shackles: Feature a threaded pin for easy fastening and removal.
    • Bolt-Type Shackles: Include a bolt, nut, and cotter pin for enhanced security during lifting operations.

Lifting shackles are an indispensable tool in rigging and hoisting applications, offering versatility and reliability in industrial settings.

“Do’s” and “Dont’s” with Lifting Shackles

This short list of do’s and don’ts is intended to inform or remind you of those guidelines.

DO’s:

  1. Check the shackle pin and body for deformation, cracks, or excess wear before each lift.
  2. Avoid sudden acceleration, deceleration, or shock loading.
  3. Check with the manufacturer about chemical effects on a shackle when used in a caustic or acidic environment.
  4. Remove damaged shackles from service immediately.
  5. Remove any shackle from service where the rated capacity is not legible.
  6. Check with the manufacturer about the loss of rated capacity when side loading or working in environments below -40° F or above 400° F.
  7. Connect multiple sling legs to the shackle’s body, never to the pin itself.
  8. If using a shackle with synthetic slings, ensure the shackle is big enough to avoid pinching or binding the sling.
  9. When using a shackle with wire rope, the shackle must be equal to or greater than the wire rope diameter. Learn more about D/d ratio here.
  10. Always ensure shackle pins are properly engaged.

DONT’s:

  1. Never load a lifting shackle beyond its safe working load limit.
  2. Do not force, hammer, or wedge a shackle that is too small into position.
  3. Never allow shackle pins to come in contact with moving parts if the pin can roll and unscrew.
  4. Do not weld onto a shackle body or pin.
  5. Never substitute a shackle pin with anything other than the exact replacement pin from the manufacturer.
  6. Do not exceed the included 120-degrees for the angle when using multiple sling legs.
  7. Never sideload a round pin shackle.

Make it a practice to keep these guidelines in mind whenever you’re using a shackle in your lifting operations. This information is general, only covering the main points for the safe use of shackles. It may be necessary to supplement this information for specific applications.
