A Quick List of the Different Types of Rigging Shackles
A shackle is used in applications to provide a link between rigging equipment and the material you’ll be lifting and hoisting around a job site. Each job you perform may require a different type of mechanism, so don’t make the mistake of choosing one that is inappropriate for the job. Browse through the common shackles below so you can become familiar with them.
D or Chain Shackles
A D shackle is shaped like—you guessed it—the letter D. Its nickname, chain shackle, is a literal term because you would use this mechanism with a chain, as the bow is narrow. This hardware is the most appropriate for performing a straight in-line loading and pulling application. Note: do not use this shackle for side or rack loading because it can damage or bend the bow.
Bolt Anchor Shackles
You would secure this type of shackle to equipment through a bolt, nut, and cotter pin. This mechanism works for semi-permanent jobs and will remain secure through twisting and torque. Since bolt-type anchor shackles have a cotter pin, you won’t have to re-tighten the shackle between each load or lift.
Screw Pin Shackles
If you plan on removing a rigging shackle from equipment, screw pin shackles work great for temporary applications. You can utilize this hardware for side loading, but vibrations could cause the pin to wiggle free—if this is the case, a different type, like a bolt shackle, would be the better option. Because this mechanism allows for more movement, you will need to tighten the screw pin after each load.
Some instances may call for a very specific type of shackle only used within that industry. For example, a snap shackle can be found in marine and sailing applications because the stainless steel material is corrosion-resistance—perfect for saltwater. (Although, the metal can still rust, so you must clean the hardware with fresh water from time to time.) Choose a long-reach shackle in construction zones if you’re lifting dense products or need a longer reach through the equipment.
Do not make a mistake on the worksite by choosing a shackle that is inappropriate for the job. Ensure you use the best hardware to promote safety. Find shackles for your application on our website at American Cable Rigging.
