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

DO:

  • 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.

DON’T:

  • 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
    lifted.

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.

Product Spotlight | Hammerlock Coupling Links

Product Spotlight: Hammerlock Coupling Links

What is a Hammerlock Coupling Link?

Hammerlock coupling links are used for attaching chain to master links, eye type hooks, installing a new branch to a sling or just connecting components during chain sling fabrication.

Hammerlock coupling links should NEVER be used to repair hoist chain—No coupling hardware should ever be used to repair a damaged link of chain. This can present a number of safety hazards to the operator and possibly the overall hoist. In the case of hoist chain damage or ware, the chain needs to be replaced as one piece.

Hammerlocks are also not appropriate for lengthening chain. Once again, if you desire a longer chain, you need to seek out a chain that is fabricated to the correct length, using the correct links.

Assembly and Disassembly of Hammerlock Coupling Links

Hammerlock coupling links are a favorite of riggers because they can so easily be assembled and disassembles in the field using only a hammer and punch.

How to assemble a hammerlock link:

  1. Bring the two halves of the body together so the center connectors are aligned
  2. Position the bushing in the center of the hammerlock, aligned with the connectors
  3. Insert the load pin through the hammerlock as far as you can by hand
  4. Hammer the load pin the rest of the way in, until all material is flush on both ends

 

Did you know the bushing in the center is one of the most important parts of a hammer coupling link? Without the bushing, the load pin on its own will not hold the hammerlock coupling together at all – It actually moves quite freely within the body on its own. The load pin is tapered on the ends which allows the bushing to sit in place and hold the hardware securely together. The bushing contains a spring-like system that allows the pin to push through when hammered, but returns to an un-movable state once in place – Unless directly hammered again using a punch!

How to disassemble a hammerlock link:

  1. Place the hammerlock link on a raised surface, creating room for the load pin to exit the bottom
  2. Align a punch with the center-top of the load pin
  3. Hammer the punch forcing the load pin out from the center of the hammerlock
  4. Pull now loosened parts apart by hand – It’s that easy!

Product Spotlight: YOKE Swivel Self-Locking Hooks

Product Spotlight: YOKE Rigging Hardware 

Concerned about price, quality & reliability? Choose YOKE, and get all three without making a sacrifice. YOKE swivels are manufactured with the highest grade materials, and are zinc-plated for corrosion resistance and a long life.

WHY USE SWIVEL HOOKS?

Swivel hooks come in two varieties. These are:

  • Positioning Hooks allow the rigger to align the hook while connecting to the load. These hooks aren’t meant to rotate while under load, only to position the hook to the pick point.
  • True Swivel Hooks with Bushings allow the hook to rotate freely under the load, while the top coupling/fitting pivots to let the load rotate. This helps prevents your line twisting.

Swivels should be used when the lift deals with these issues:

  • Swivels reduce bending loads on rigging attachments to allow the load to position itself freely.
  • Swivels should be used in place of shackles during applications where the shackle might twist and might be haphazardly loaded.

FYI: Before you lift a load, make sure there are not cracks or defects in the hook or latch, and that the chain or wire rope is not worn, and in good working order. Not all hooks are meant to overhead lift and not all swivels are meant to swivel under-load—It’s important to know which application the one you use is meant for.

Swivel self-locking hooks should only be used to swivel under-load if they’re fit with a bearing and are approved by the manufacturer overhead lifting. Swivel self-locking hooks are generally known as positioning hooks, since they rotate which makes connecting the rigging to the load much easier.

Industries that use YOKE Swivel Self-Locking Hooks, include:

  • Automotive
  • Construction
  • Mining
  • Manufacturing
  • Machining
  • Transportation
