Hoist Ring Swivels
Introduction to Swivel Hoist Rings
A swivel hoist ring works much the same way as a
lifting eye bolt and has a fully threaded shank with inch or metric threads. It is intended for use with tapped holes that have been engineered as a lifting point for industrial machinery.
Swivel hoist rings feature a 180-degree pivot and 360-degree swivel to allow for lifting from any direction, where a sling is generally connected to the bail of the hoist ring to facilitate the lift. Their versatile design allows for easy attachment to various rigging points to absorb any pitch, roll, or sway of an unbalanced load in order to complete the lift safely.
Application Considerations
As hoist rings are used for lifting, there are several factors to consider before using them. Here are a few general suggestions, but you should do your own research on the individual part in question.
Load Requirements:
It is essential that you understand the weight of the load your ring will bear. A miscalculation could negatively impact the ring's performance, which may result in damaged equipment or dangerous conditions for workers.
Load Movement:
The ring is meant to absorb pitch, roll, and sway in a moving load. However, it is important that you have an idea of how much movement may be involved so you can choose the ring or adjust the application setting appropriately.
Environmental Elements:
Will your ring be exposed to elements like water, temperature fluctuations, or corrosive elements? This will impact how you choose the material and finish of your ring.
Safety: Before using your ring, ensure that it and the other elements of your application meet the safety regulations, training requirements, installation standards, and inspection thresholds needed to perform your work.
Benefits
There are several key benefits that hoist rings offer in a lifting application:
Load Stability:
Since the hoist ring swivels, it allows the load to remain stable in its position because the ring compensates for the motion; this reduces the risk of accidents during performance.
Versatility:
The range of the ring's swivel and rotation allows workers to align and position the load without putting extra strain on equipment or themselves.
Durability and Longevity:
Huyett's swivel hoist rings are made from alloy steel and 300 series stainless steel with black oxide and polished finishes, all of which offers unique strength and corrosion-resistant elements to the part.
Reusability:
As long as the hoist ring is properly installed, the threads are not stressed, and it is undamaged, it is a great investment as a reusable part.
Rated Capacity:
The rated capacity (or maximum working load limit) of Huyett's swivel hoist rings ranges from 400 lbs. - 35,000 lbs. and 500kg - 32,500kg, allowing for a wide range of application uses.
Product Line
At Huyett, we take pride in offering premium-quality hoist rings that meet the highest industry standards. That's why we offer them through our
Aztec Premium Lifting Hardware line, which also offers a wide range of other hardware like
lifting eye nuts,
clevis and yoke ends,
turnbuckles, and more.
Installation
To install a swivel hoist ring, you must typically use a torque wrench to control the torque value you apply to the ring. Unfortunately, many rings are tightened until they no longer turn, which stresses the threads and does not comply with installation requirements.
Each ring is assigned a torque value, which is provided by the manufacturer and found in the individual product details. It is important to comply with that value during installation. Too much torque will stress and potentially damage the threads, while too little will prevent the ring from fully connecting to the load and may loosen while in use.
Important Safety Measures
As previously mentioned, there are several important safety measures to consider when using a hoist ring. These are a few general guidelines, but you should always do specific research on the part to ensure it aligns with the safety and performance regulations in your application.
Regular Inspections:
Prioritize routine inspections of the hoist rings to identify any signs of wear, damage, or deformities. Replace any faulty components immediately.
Correct Attachment:
Properly attach the swivel hoist ring to the load using the recommended rigging hardware. Incorrect attachment can lead to accidents and damage to the hoist ring.
Training and Certification:
Ensure that operators are adequately trained in using swivel hoist rings and possess the necessary certifications to perform lifting tasks safely.
Difference Between Swivel Hoist Rings and Lifting Eye Bolts
While these two types of hardware are often used in similar applications, there is a significant difference in their design and lifting capabilities.
In short, swivel rings are designed to handle a moving a load, while a lifting eye bolt is meant to handle straight-line lifts. A
lifting eye bolt is a straight bolt with an eye at the top that attaches to rigging equipment. The eye has different designs - some are closed, some are opened, and some sit atop a shoulder that provides support to some angled loads (if you factor in a reduced load limit).
Eye bolts are much more economical than the swivel ring and are a great choice for lighter loads that do not need to account for movement. However, if you know your load might sway, roll, swing, etc., the swivel ring is much more suited for the application.
