Lifting with Fabricated Hardware

Hoist Rings and Lifting

In the world of lifting and rigging, hoist rings are a proven lifting solution when a safe lifting plan is designed. The ability of a hoist ring to be used in combination with fabricated lifting plates that can be attached to a load can open opportunities for different lifting lug types. While the fabricated lifting plate will not swivel, the hoist ring will act as a lifting swivel for the plate. The final design which needs to be properly engineered and tested with the hoist ring incorporated may also be known as a lifting ring assembly.

More Eye-Bolt Considerations

Shouldered eye-bolts– when do we use them?

An important consideration when choosing which eye-bolt to use for your lift is whether or not it needs to be “shouldered.” Bolts that do not have shoulders are only used for vertical lifts. If, however, your lift needs to be done at an angle, it is important to use a shouldered eye-bolt instead.

Eye-bolts– galvanized vs. stainless steel:

Galvanized eye bolts are coated in zinc oxide in order to prevent corrosion and oxidation over time. They tend to be less expensive than stainless steel eye-bolt, but are still a good choice for many lifts.

There are many considerations when choosing which eye-bolt to purchase for your lift. That’s why we always recommend contacting our support staff, who are experts that can help you find the safest and most economical eye-bolt for your project.

What is an Eye-Bolt?

Eye-bolts: what are they?

Simply put, an eye-bolt is like a regular bolt, except it has a loop (an “eye”) at the end of it. This added loop makes it easy to run cables, ropes, etc., through the bolt.

What is the difference between forged and bent eye-bolts?

The main difference is that forged eye bolts are better for heavy-duty lifting applications. Bent eye-bolts are made by the metal into a loop. The bent eye bolt may bend during larger lifts, whereas forged eye-bolts can withstand much heavier loads.

What is a screw eye-bolt?

Another common type of eye-bolts is the screw eye-bolt. Screw eye-bolts are similar to other eye-bolts but have the added advantage of having threads. We’d recommend taking a look at our selection of products to see all the eye-bolts that ADB has to offer and contact our service team if you have any questions.

More about Swivel Hoists

Swivel hoists vs. Eye-bolts:

Swivel hoist rings were developed to overcome the deficiencies of eye-bolts as a result of angular loading. Unlike eye-bolts, the hoist ring design provides the ability to pivot 180° and swivel 360° to compensate for load pitch, roll, or sway when lifting unbalanced loads. ADB is the originator of the safety-engineered hoist ring and has been providing reliability since 1964. ADB hoist ring CAD models are readily available at www.adbhoistrings.com, and our knowledgeable staff of engineers can be consulted for customizations or technical questions.

ADB Swivel Hoists

ADB hoist rings have been designed and tested to meet ASME B30.26-2 user specification requirements. Design requirements include proper working load limit and fastener torque markings, a 5:1 design factor, specific length thread projections, and suitable materials to meet the product specifications. While proof testing is not a requirement for newly manufactured hoist rings, ADB proof tests to 200% each center-pull style hoist ring with a working load limit up to 30,000 lbs. before shipment (150% for stainless steel).

Hoist Ring Installation

ADB hoist rings can be properly installed using a tapped or “through” hole with an ADB approved nut and washer attached on the opposite side. When installed properly, all ADB swivel hoist rings freely swivel 360° and pivot 180°. Although hoist ring working load limits do not change or have to be reduced during angular loading, be aware that angular loading does increase the load on all components in the rigging configuration including the hoist ring. It is the responsibility of the user to understand and take into consideration the additional loads being applied as a result of angular loading.

Don’t Forget Your Lift Points : HOIST RINGS In Design

Demanding deadlines leave a natural opening for omissions or errors to even the most thought-out design plans. After many hours of excruciating drawings and calculations, engineering designs come to fruition and are assigned to the job shop. Accomplishment throughout the engineering department is felt until one question arises from the shop floor, “how will you lift your design?” This question has caused the blood to quickly exit many engineers’ faces and sickness to be felt. All feelings of loss would have been avoided if the design of the lifting points and the proposed lift plan were not excluded.

In most designs requiring lifting or rotation applications, hoist rings, which are engineered lifting points, are readily available for most applications with working load limits ranging from 250 lbs. to 500,000 lbs. Hoist rings are engineered so that they swivel 360 degrees and pivot 180 degrees. Hoist rings are a natural choice for designs that require lifting points because hoist rings are designed to be threaded into a tapped hole or used in a thru-hole application with a nut and washer. Also, hoist rings are available to meet all standards of ASTM B30.26, which includes requirements such as a 5:1 design factor. The past times of “homemade” lift points are now over with such clear standards relating to safety in the workplace and devices related to overhead lifting.

ADB® is a manufacturer of hoist rings and has an engineering staff that specializes in customized engineered lifting point designs.

Answering Common Questions about Hoist Rings

What is a hoist ring?

A hoist ring is a critical component that helps facilitate lifting heavy loads. They are a type of lifting ring that connects a sling with a lifting hoist to raise and lower heavy-duty loads. They are useful because they allow a more extensive range of motion than other types of lifting rings that serve similar functions– such as eye bolts and eye nuts. Because of this added flexibility, hoist rings increase the safety of your lift. If your lift involves applying force at an angle, your best bet is to use a hoist ring.

How to install a hoist ring?

The most crucial consideration is putting safety first. Please refer to our general safety and installation guide for a complete, in-depth overview of installing different lifting components.

For more information on installing particular hoist rings, see the installation instructions tab on our Safety and Technical Page. There you will find instructions on how to install EZ-Torque® Hoist Rings, Fast-Lok® Plate Systems, Heavy Duty® Weld Mounts, and Welding Instructions for Weld-in Threaded Inserts.

Can a swivel hoist ring be installed in a through hole?

The answer is yes: a swivel hoist ring can be installed in a through hole. However, when installed in a through hole with a nut and washer, the nut must be at a Grade 8 strength level, and the nut must also have full thread engagement.

ADB provides nuts and washers for through hole applications, and can also customize the bolt/thread length to pass through plates or through holes. For more information on ADB products and services, please head over to our contact page to get in touch with us.

ADB Safety Engineered Hoist Rings

Saftey Engineered Hoist Rings and ADB:

One word: safety. Only ADB produces the original Safety Engineered Hoist Ring. Unlike similar products, ours do not require putting a hole through the shoulder pin. Why is this important? Because those that are installed with roll pins are more likely to shear. When they shear, they may let the shoulder pin come out. This safety feature also allows our Safety Engineered Hoist Rings to be more easily disassembled and reassembled for safety testing. This feature is not available on the products of our competitors. ADB’s safety engineering makes our hoist rings the best choice for lifting and lowering heavy-duty loads.

Custom Hoist Rings: does ADB offer them?

Yes! ADB strives to meet all of our clients’ individual needs. We understand that across the broad range of industries we serve– such as aerospace, manufacturing, construction, etc.– there is no “one size fits all” solution. Therefore, in addition to our comprehensive line of safety lifting devices, we also offer customized equipment. If you have a lift project with unique specifications and requirements, we will be happy to assist you. We have an experienced team of associates who can work with you to produce the perfect safety lifting devices for the job.
