CHOOSING THE RIGHT RIGGING HARDWARE FOR THE JOB

Shackles, Slings, and Hooks Explained

 

When it comes to rigging, using the right hardware isn’t just a matter of efficiency—it’s a matter of safety. Whether you’re lifting heavy loads on a construction site, in a manufacturing facility, or at sea, your choice of rigging hardware can make or break the job. At CERTEX, we understand that the variety of rigging gear available can feel overwhelming, especially when stakes are high. This guide breaks down three of the most commonly used components—shackles, slings, and hooks—and can help you choose the right tool for the task.

 

Shackles: The Reliable Connectors

 

What They Are:
Shackles are U-shaped pieces of metal secured with a pin or bolt across the opening. They’re used to connect different pieces of rigging equipment—like slings, chains, or rope—to one another or to a load.

Common Types:

When to Use:

      • Connecting lifting slings to loads
      • Attaching rigging to hoists or cranes
      • When flexibility and ease of removal are required

Key Considerations:

      • Always match the Working Load Limit (WLL) to your lift
      • Ensure the pin is properly secured
      • Avoid side loading unless the shackle is designed for it

Slings: The Versatile Lifters

 

What They Are:
Slings are flexible lifting devices that attach to lifting hardware. Available in a variety of materials and configurations, slings are essential for safe and efficient lifting.

Common Types:

When to Use:

      • Lifting irregularly shaped or delicate loads (synthetic or round slings)
      • Handling abrasive or hot materials (wire rope or chain slings)
      • Where flexibility and load protection are required

Key Considerations:

      • Choose based on load weight, shape, and environment
      • Inspect slings before each use—look for fraying, cuts, kinks, or wear
      • Use appropriate sling protection to prolong life and prevent damage

Hooks: The Secure Grabbers

 

What They Are:
Hooks are used to attach loads to lifting devices such as cranes or hoists. They come in various shapes and locking mechanisms, each designed for a specific application.

Common Types:

      • Eye Hooks: Permanent installations with welded or forged eyes
      • Clevis Hooks: Used with chain; attach via pin
      • Latch Hooks: Include a safety latch to prevent inadvertent load disengagement
      • Swivel Hooks: Allow rotation of load to prevent twisting

When to Use:

      • Connecting to slings or chains in overhead lifts
      • Lifting when load control is crucial
      • When the load needs to rotate or align mid-lift

Key Considerations:

      • Always use hooks with a safety latch when lifting overhead
      • Never exceed the WLL
      • Choose the correct grade of hook for your application—higher grades (like Grade 80 or 100) are required for overhead lifting and heavy-duty jobs
      • Ensure compatibility with the rigging and load
🔎 Pro Tip: Match the hook grade to the grade of the chain or rigging system you’re using. Using incompatible components can compromise safety and performance.

 

Making the Right Choice

 

When choosing rigging hardware, keep the following in mind:

      • Load Type & Weight: Know your load’s exact weight and center of gravity
      • Environmental Factors: Consider temperature, moisture, and exposure to chemicals or abrasives
      • Frequency of Use: Permanent vs. temporary setups may require different types of hardware
      • Inspection & Maintenance: Regular checks prevent accidents—replace worn or damaged equipment immediately
      • Compliance: Use hardware that meets industry standards (like ASME, OSHA, or manufacturer guidelines)
