Description
When it comes to cranes, shackles are essential rigging components used to connect slings, wire ropes, or other lifting accessories to the crane hook. Their primary function is to provide a strong and secure point of attachment. Different types of shackles are used depending on the specific application, the load capacity required, and the working environment. Here are the main types of shackles commonly used for cranes:
1. Bow Shackles (or D-Shackles)
- Description
This is the most common type of shackle. It has a “D” shaped body and a pin that closes the loop.
2. Dee Shackles (a specific type of Bow Shackle)
- Description
Similar to a standard bow shackle, but the body is narrower and more defined in a “D” shape. Often used when space is limited or when connecting to specific types of hardware.
3. Anchor Shackles
- Description
These shackles have a wider, rounded “U” or “O” shaped body. They are designed to accommodate multiple sling legs or to handle loads that might put stress on the sides of the shackle.
4. Twist Shackles
- Description
These shackles have an angled or twisted body. They are used to connect a single sling to a crane hook where a direct alignment might be difficult, or to prevent the sling from twisting.
