LFT Swivel Hoist Rings offer great features like a high-visibility, widened reinforced bail, and a corrosion-resistant coating. So today we’re going to highlight the premium features of the LFT swivel hoist rings and teach you how to properly select and operate them.
LFT Key Features
Let’s go over some of the key features that make LFT swivel hoist rings stand out compared to similar hoist rings.
All parts of LFT Swivel Hoist Rings are non-destructive tested using the Resonant Acoustic Method to make sure that every component is solid and ready for service. They feature a durable powder coated painted finish over a GEOMET coating for high-tech corrosion resistance, that exceeds the performance of hot dip galvanizing. Each LFT Hoist Ring comes permanently marked with an individualized serial number, load rating, torque specification, and part number Last but certainly not least, they’re manufactured here in the US, and feature an oversized forged alloy steel bail, which is individually load tested to 200% its rated working load limit.

Selecting LFT Swivel Hoist Rings
First confirm the required thread diameter, pitch and depth of the object you're planning to lift. LFT Swivel Hoist Rings are available in thread diameters from ¼” to 2”, thread lengths from ½” to 2 ½”, and are available in both fine and coarse threads.
You'll also want to confirm the number of rings hoist you'll be using and required working load limit. These swivel hoist rings have a 5:1 design factor and are available in working load limits from 550 to 30,000 pounds.
Finally, don’t forget to measure the lifting assembly connections to confirm that they will fit comfortably within the opening of the bail.
LFT Swivel Hoist Ring Installation and Operation
LFT Swivel Hoist Rings need to be properly installed and operated, since improper practices can create unsafe working conditions and lead to failed lifts.
To install the LFT Swivel Hoist Ring, first ensure the surface of the object is flat, smooth, and of suitable strength around the threaded receiving hole where you intend to install the Swivel Hoist Ring. This is important since full bushing contact with the surface allows for full compression at the recommended torque.
Next, ensure the threads are clean and dry. The recommended torque value is based on non-lubricated threads that are clear of debris.
Once the surface is ready, lay the bail flat and begin to thread the torque bolt until it is hand tight.
Grab your torque wrench and refer to the recommended torque value for the correct pounds of force per foot needed for the swivel hoist ring. You can find the recommended tightening torque on the swivel hoist ring itself and in the spec sheet on its respective product page.
Begin carefully torquing the bolt until the torque wrench reaches the recommended tightening torque.
After installation, always check that the ring rotates and pivots freely in all directions. You’re now ready to attach and lift the object using the LFT Swivel Hoist Rings.
LFT Swivel Hoist Ring Operational Guidelines
When lifting objects with the LFT Swivel Hoist Rings, it’s important to follow these lifting practices to ensure a safe working environment.
Prior to lifting with hoist rings, first read the entirety of our proper installation and use the guide.
After the lifting assembly has been properly applied to the hoist ring, apply force slowly. Make sure the bail is parallel to the direction of the load and there are no twists in the rigging assembly. Have spotters keep an eye on all positions and be prepared to stop applying force if the load starts to buckle.
When attaching your lifting assembly, never “reeve” or feed slings from one hoist ring bail to another.
If you’re lifting an object from the side-mounted position with the rings at a 180-degree angle, use a spreader bar to ensure the rings are not put in a bind against the edges of the object.
The tensile strength of the material to be lifted should be at least 80,000 PSI for full load rating. For lower tensile materials, increase thread length or use a thru-hole with a nut and washer on the other side.
Never use a washer or spacer between the bushing and the surface of the object. The washer already mounted on the LFT Swivel Hoist Ring is designed to work in conjunction with the rest of the components at its rated working load limit.
