5 Important Rules To Follow When Using Rigging Shackles
There are five important rules to follow when using rigging shackles, and they are in place to aid in worker safety and job efficacy. They are critical components in managing load weights on a variety of applications. Before you begin work with shackles and equipment, take a look at the rules and how they apply to your team or tasks.
It’s essential to attach the sling’s legs to the bow instead of the pins. You can weaken and damage the sling by not correctly connecting the components. With enough improper attachments, you risk worker safety.
You want to ensure your connections are correct. You want to avoid attaching a point loading pin to the pin. Instead, attach the bow to the pin or the bow to the bow. Like we state in rule number one, improper connections can damage the equipment.
You cannot sideload shackles in D-shape. This refers to chain or long-reach shackles. Chain and long-reach shackles work best for in-line tension applications. A good rule of thumb is to line up the center lines on both the load and the shackle. Bolt type anchor shackles can withstand a side load, but it’s best to refer to the rating charts for this specific rigging application.
The shackle’s bow is critical when securing the load. So, ensure these connections go through the side of the choke.
If your shackle houses wire rope, the shackle must be the same size or larger than the diameter of the wire rope.
A few other important rules to follow when using rigging shackles include the following:
- Avoid exposing shackles to extreme temperature fluctuations.
- If the sling is synthetic, ensure the size of the shackle can accommodate the sling to avoid binding or pinching.
- If the application is semi-permanent, use a bolt cotter anchor shackle. Especially if they help suspend a load.
- Ensure complete engagement on the shackle’s ear with the screw pin threads.
