Product Spotlight: Swivel Hoist Ring
What is a Swivel Hoist Ring?
A swivel hoist ring is a type of heavy-duty lifting ring that is used with a hoist to lift or lower a load. It is often the hardware of choice when the object being lifted has no clear attachment points, as the hoist ring is able to be screwed directly into the surface of the load. Once the swivel hoist ring is successfully installed, it essentially creates an attachment point for your hoist chain to attach to.
Swivel hoist rings are of a similar design and intended use to the eye bolt, a piece of hardware that has been around for a very long time in the rigging world. While standard eye bolts are effective when used properly for a suitable job, they often fail when put at any amount of angle. If the load shifts causing the direction of the load to be as much as 10 degrees off the line of force, you could have a bent eye bolt. This can result in a failed lift, causing damage to your load, property damage, and injury to workers.
Swivel hoist rings are designed to lift at any angle because they can swivel 360 degrees and pivot 180 degrees. A swivel hoist ring can rotate with the direction of force without loosing rated capacity, which gives increased safety and peace of mind. When a load is lifted or lowered, wind gusts may cause it to turn—This can result in the chain or rope getting twisted together with static hardware. Swivel hoist rings solve this problem by allowing the load to rotate back and forth as it needs without twisting the chain or rope.
The Do’s and Don’ts of Installing and Using Swivel Hoist Rings
- Always read the safety precaution page prior to use or installation.
- Inspect the hoist ring before each use – see below for what you should look out for when doing this!
- Choose a hoist ring with the proper load rating.
- Only use hoist rings in materials that have a tensile strength of at least 80,000 psi.
- Make sure the thread engagement is at least 1.5 times the diameter of the
hoist ring screw.
- When installing a hoist ring in a through-hole with a nut and washer, make sure to use a Grade 8 nut that has full thread engagement.
- Consider periodic load-testing as an extra precaution.
- Never exceed the rated load limit or apply shock load.
- Never use a hoist ring that you believe may be damaged – it’s not worth the risk!
- Never use a hoist ring that is not tightened to the recommended torque.
- Never replace the components of the hoist ring.
- Never use a hook larger than the diameter of the hoist ring opening.
- Never shim or use washers between the hoist ring and surface of the object being
Swivel Hoist Ring Inspection and Maintenance
Always inspect the hoist ring before each use, make sure that:
- The screw is tightened to the recommended torque using a torque wrench – If it’s not, the threads may be stripped on a vertical lift.
- The bushing of the hoist ring is sitting flush against the object being lifted – This ensures that the hoist ring is able to reach its full 5:1 safety factor.
- The hoist ring is free to swivel and pivot in every direction – If the hoist ring binds up in any direction, it should not be used.
- There are no signs of corrosion – This can result in the hoist ring cracking or binding up.
- There are no signs of wear or damage, especially on the screw, shoulder pins, and bail – Damage may be an indicator that the hoist ring is coming into contact with something during use. This should be avoided as such contact can cause binding and shock loads, which exceed the rating of the hoist ring.
- The shoulder pins are secure and do not rotate or come loose – This can be checked by using pliers to try to rotate the shoulder pins by hand. If it does rotate, it should not be used as this could cause the hoist ring to come loose or break during use.
