Screw pin shackles are designed with a threaded pin that secures the connection while allowing for ease of use.

• Applications:
  • Temporary lifting and rigging
  • When frequent assembly and disassembly are required

Safety Pin Shackles

These shackles feature a safety pin to ensure that the pin remains securely in place, minimizing the risk of accidental disengagement.

• Applications:
  • High-risk lifting situations
  • Environments where safety is a top priority

Quick Release Shackles

Quick release shackles allow for rapid attachment and detachment, ideal for operations requiring speed.

• Applications:
  • Emergency rescues
  • Situations where time is of the essence

Choosing the Right Shackle

Selecting the appropriate shackle for your application is essential for safety and efficiency. Here are key considerations:

• Load Capacity: Ensure the shackle's working load limit (WLL) meets or exceeds the load requirements.
• Material: Shackles can be made from various materials, including steel, stainless steel, and aluminum. Choose based on environmental conditions, such as corrosion resistance or weight.
• Type of Application: Consider whether the shackle supports permanent or temporary connections.

Common Problems and Solutions

1. Incorrect Load Capacity:

   • Solution: Always check and validate the WLL before use. Consult the shackles supplier for specifications.

2. Corrosion Issues:

   • Solution: Use stainless steel shackles in marine or wet environments. Regular inspections can help identify early signs of corrosion.

3. Pin Disengagement:

   • Solution: For high-risk lifts, opt for safety pin shackles to minimize disengagement risks.

4. Overloading:

   • Solution: Educate your team on safe lifting practices and the importance of adhering to load limits.
