A Quick Overview of How Rigging Shackles Are Sized

Not every rigging application will use the same sling or shackle to safely secure and lift a load. This article gives a quick overview of how rigging shackles are sized, so you can understand better which type of equipment is best for your load. Enhance the safety of your worksite and be familiar with how to choose the proper shackles.

What Is the Importance of Rigging Shackles?

Rigging shackles are highly important for applications because you wouldn’t be able to hoist a load without them. These devices are the main point of contact between the sling around your palette or container and the lifting equipment. The shackle attaches to both components, so you can safely maneuver and lift a load into the air.

Why the Size of the Shackle Matters

The size of the shackle directly correlates with the amount of weight the equipment can carry during a rigging application. A product tolerance limit should be clearly printed on the shackle so you always know what kind of equipment you’re grabbing. Using an inappropriate device for rigging could result in injury and limit worksite safety. For example, never use a particular shackle if the distance between the eyes is greater than the manufacturer’s recommendations—this equipment is sized through the diameter of the bow and not by the size of the pin.

What Types of Shackles & Pins Can You Choose From?

Now that you have an overview of how rigging shackles are sized, what type of shackles and pins can you choose from? Shackles come in various styles, including dee, piling, screw pin, and safety pin. The pins you can select, such as screw pin anchor, screw pin chain, round, and bolt type, are also configurations you should keep in mind when choosing a shackle.

Screw pin anchor shackles are generally for temporary applications, while bolt-type shackles are best for permanent use on the same equipment. Screw pins are much simpler to set up and do not add friction to the payload. Bolt pins take more time and components to assemble but provide better liability to the movement of the load. Keep in mind your load weight and the type of product you’re hoisting to better decide which type of shackle is best for your application.

Shackles are an essential part of rigging equipment. Without these devices, we cannot lift palettes or containers. Be familiar with the sizing and configurations on the shackles to be more successful in rigging loads.
