Key Benefits
What 322C Swivel Eye Hoist Hook Grade 43 Gives You
- The swiveling upper link allows the hook to rotate freely, preventing wire rope from twisting under load
- Spring-loaded latch secures the load and prevents accidental disengagement during lifting
- Drop-forged carbon steel body with quench and temper treatment provides high strength and impact resistance
- 5:1 safety factor ensures the minimum breaking load is five times the safe working load
- Powder coated or painted finish resists corrosion in marine, outdoor, and industrial environments
- Compact design reduces weight while maintaining full load capacity, improving handling and rigging speed
- Traceability marking stamped on the body allows for load history and compliance tracking
Application Scenarios
Where 322C Swivel Eye Hoist Hook Grade 43 Is Used
- Marine and offshore lifting where wire rope must remain untwisted during hoisting on ships or platforms
- Construction site operations using cranes to position steel beams or precast panels with minimal rope twist
- Material handling in factories where rigging lines are repeatedly engaged and disengaged
- Rigging setups requiring precise load alignment without manual adjustment of the hook
- Mobile crane operations where load rotation is unpredictable and constant repositioning occurs
Who It Is For
Buyers This Product Is Built For
- Marine and offshore contractors sourcing lifting hardware for vessel and rig maintenance
- Construction companies specifying lifting hooks for crane-based steel and concrete handling
- Industrial rigging teams managing repetitive lifting tasks with wire rope systems

Problems It Solves
Problems This Product Removes
- Wire rope coiling or twisting during lift due to a fixed hook, which can lead to rope damage and failure
- Accidental load release from a hook without a latch, especially during dynamic or overhead lifts
- Need to manually reposition the hook to align the load, slowing down rigging cycles
- Lack of traceability in the field when a hook fails or requires audit
- Buying a swivel hook and a separate latch or link from different suppliers, increasing procurement complexity

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 eye hook | The swivel version prevents rope twisting and reduces wear, but adds a moving part that requires periodic inspection |
| Non-latching hook | The spring-loaded latch prevents accidental load drop, but the latch mechanism adds complexity and may require cleaning in dusty environments |
| Screw pin hook | The swivel hook with latch is faster to engage and safer for dynamic lifts, but a screw pin hook allows for easier visual inspection of the pin position |
| Soft sling hook | Steel hook handles abrasion and high loads better than a soft sling, but is heavier and less flexible in certain rigging configurations |
Use Guide
How To Use And Inspect 322C Swivel Eye Hoist Hook Grade 43
- Match the stamped WLL to the calculated load, not to the crane or winch rating
- Ensure the spring-loaded latch is fully closed before lifting and check it remains engaged
- Inspect the swivel link for free rotation and absence of grit or binding before each use
- Do not exceed the maximum working load limit marked on the hook
- Retire the hook if the body shows deformation, the latch fails to close, or the marking is illegible
- Keep the hook clean and dry, especially in marine or corrosive environments
