People will use shackles in various applications to provide a link between rigging equipment and the material they will be lifting and hoisting around a job site. Knowing the different types of rigging shackles is essential since 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. Please browse through the common rigging shackles below so you can become familiar with each one of them and make the best decisions for your projects.
D or Chain Shackles
A D shackle has a shape 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 these types of rigging shackles for side or rack loading because they can damage or bend the bow.
Bolt Anchor Shackles
You would secure this type of shackle to equipment with the help of 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 rigging 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 these types of rigging shackles for side loading, but vibrations can cause the pins to wiggle free. If this is the case, a different type, like a bolt shackle, would be the better option for you to use. Because this mechanism allows for more movement, you will need to tighten the screw pin after each load.
Specialty Shackles
Some instances may call for very specific types of shackles that you only use within specific industries. For example, you can find a snap shackle in marine and sailing applications because the stainless steel material is corrosion-resistant —which makes it perfect for use in saltwater applications. But don’t think this leaves you free of any maintenance responsibilities. The metal can still rust, so you must clean the hardware with fresh water from time to time. You can choose a long-reach shackle for use in construction zones if you’re lifting dense products or need a longer reach through the equipment.
Do not make mistakes on the worksite by choosing types of rigging shackles that are completely inappropriate for your jobs. Ensure you use the best hardware to promote safety. Find the proper rigging shackles for your application on our website at American Cable & Rigging Supply.
