Grade 80 Links
Swivel Hoist Ring/G80 Universal Swivel Eyebolt with Ring
A Grade 80 alloy steel swivel hoist ring with a 360-degree rotating ring and 180-degree flip capability, designed for lifting applications where load orientation changes during hoist. The ring rotates freely to prevent rope twist and allows alignment with the load path. Available in thread sizes from M8 to M100, with safe working loads from 0.3T to 40T. The body is quenched and tempered, painted red or yellow, and marked with WLL, manufacturer ID, CE, and size. Minimum breaking load is four times the WLL.

Key Benefits
What Swivel Hoist Ring Gives You
- 360-degree rotation and 180-degree flip prevent rope twist and maintain load alignment during lift
- Swivel action reduces stress on the lifting line and fittings in dynamic or angled lifting scenarios
- Grade 80 alloy steel body quenched and tempered for high strength and impact resistance
- Painted finish in red or yellow for visual identification and corrosion resistance
- WLL, manufacturer ID, CE, and size stamped on the body for traceability and compliance
- Designed to work with other Grade 80 components to maintain system integrity
- Compact design replaces multiple rigid lifting points in complex rigging setups
Application Scenarios
Where Swivel Hoist Ring Is Used
- Offshore platform lifting where the load orientation shifts during hoist and rope twist must be avoided
- Heavy equipment installation in confined spaces with limited clearance for fixed lifting points
- Marine cargo handling where the load may swing or rotate during lifting and winching
- Industrial crane operations with multi-directional pull angles requiring dynamic alignment
- Construction site rigging where the lifting point must adapt to changing load angles
- Temporary rigging setups with moving loads where fixed rings would bind or fail
Who It Is For
Buyers This Product Is Built For
- Marine and offshore contractors specifying lifting hardware for vessel and platform work
- Construction and infrastructure firms managing complex crane lifts with variable angles
- Industrial rigging teams handling heavy machinery with dynamic load paths
- Logistics and transport operators managing cargo with irregular shapes and shifting centers
- Manufacturers of lifting kits and rigging systems needing a swivel option in their range
- Procurement engineers sourcing a single supplier for Grade 80 lifting components
Problems It Solves
Problems This Product Removes
- Rope twisting and tangling caused by fixed lifting points during angled or dynamic lifts
- Misalignment between the hoist line and load path due to rigid attachment points
- Premature wear on synthetic or wire rope from repeated bending and friction at fixed points
- Need to use multiple lifting points or complex rigging to compensate for lack of rotation
- Incompatibility between Grade 80 components when mixing with lower-grade hardware
- Buying swivel rings from separate suppliers while needing a consistent material grade and marking

How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Fixed lifting ring | The swivel ring prevents rope twist and allows load alignment but adds a moving part that requires inspection for wear |
| Screw pin shackle | The swivel ring offers full rotation and is more compact than a shackle with a separate pin, but it cannot be opened for attachment |
| Eye bolt with swivel nut | The full ring swivel provides smoother rotation and better load distribution than a nut-mounted swivel |
| Rigid eyebolt | The swivel version reduces line stress and wear in angled lifts but is not suitable for high-vibration environments without maintenance |
Use Guide
How To Use And Inspect Swivel Hoist Ring
- Match the stamped WLL to the calculated load, not the hoist capacity
- Ensure the swivel ring rotates freely before each lift and check for binding
- Avoid side loading the ring; keep the pull aligned with the shank axis
- Inspect the paint finish and marking for wear or damage before use
- Do not use with components below Grade 80 to maintain system safety
- Retire the ring if the swivel seizes, the body deforms, or the marking is illegible

Answers
Swivel Hoist Ring FAQ
What is the swivel range of this hoist ring?
The ring provides 360-degree rotation and 180-degree flip up and down, allowing full load orientation adjustment.
Can I use this with synthetic rope?
Yes. The smooth, rotating ring reduces friction and prevents heat build-up on synthetic lines like Dyneema.
What is the design factor?
A standard 4:1 design factor applies, so the minimum breaking load is four times the stated safe working load.
Are Material Test Certificates available?
Yes. A Material Test Certificate to EN 10204 3.1 is supplied on request with each order.
Can I get custom tonnage marking or branding?
Yes. Custom tonnage stamping, private label marking, and OEM packaging are standard options.
How are they packed for export?
Cartons on pallets as standard. We can configure carton count and pallet pattern to suit your warehouse or retail pack. Free two-month storage in Qingdao is available.
What thread sizes are available?
The range runs from M8 to M100, with WLLs from 0.3T to 40T. Full dimensions and weights are listed in the size table.
