The Grade 100 Swivel Self-Locking Hook (SSK Type) is a highly secure lifting hook designed with a rotating top and an automatic locking mechanism to ensure maximum load safety during overhead lifts.

Swivel Positioning: Equipped with a rotating top ring that allows operators to easily align the hook before lifting, preventing twisted lifting chains.
Automatic Locking: The heavy-duty latch automatically closes and locks the moment tension is applied, securely capturing the load.
Manual Trigger Release: Engineered so the hook can only be opened by manually pressing the release trigger, eliminating the risk of accidental detachment.
Grade 100 Strength: Manufactured from premium alloy steel, providing up to 25% higher lifting capacity compared to standard Grade 80 hooks of the same size.

Grade 100 Swivel Self-Locking Hook - SSK Type

Automatic Safety Lock with Positioning Swivel

Grade 100 Alloy Steel Positioning Swivel Automatic Locking EN 1677-3

*Swivel eye for easy alignment (Positioning Only)

Product Features

Automatic Locking: The hook automatically closes and locks as soon as the load is lifted. It cannot open under load, providing maximum safety for critical overhead operations.
Swivel Positioning: The rotating eye aligns the hook with the load point before lifting. This prevents the chain or wire rope sling from twisting or kinking during setup.
Trigger Release: Features a recessed trigger mechanism that is easy to operate (even with gloves) when releasing the load, but fully protected against accidental activation.
Rotation Note: This is a Positioning Swivel. It is designed to align the hook, NOT to rotate continuously while under full load (for that application, use the Bearing Swivel SSB type).

Selection: Positioning (SSK) vs. Bearing (SSB)

Model	Mechanism	Can I Rotate Under Load?
SSK Type (This Product)	Washer / Bushing	NO. (✘) Positioning only. Rotate to align the hook before lifting. Do not rotate while lifting.
SSB Type (Bearing Model)	Ball Bearing	YES. (✔) Designed to rotate freely under full load. Prevents wire rope from twisting.

Grade 100 Sling Components are high-strength alloy steel lifting accessories designed for heavy-duty lifting applications. Compared with Grade 80, Grade 100 offers higher working load limits (WLL) at the same size, or the same WLL with a smaller, lighter component.

What Does "Grade 100" Mean?

High-Strength Alloy: Heat-treated, quenched, and tempered steel.
Increased Capacity: Typically 25% higher WLL than Grade 80.
Safety Factor: Minimum breaking force ≈ 4 × WLL.
Standards: EN 818-4 / EN 818-6, ASTM equivalents.

Identification & Markings

Every Grade 100 component must be clearly marked with:

Grade: G100 or 10
Manufacturer's Mark
Size or WLL
Traceability Code (Batch / Heat Number)

⚠️ Safety & Compatibility Warning

❌ NEVER mix Grade 100 with Grade 80 components in the same sling assembly.
✅ Use only Grade 100 chain + Grade 100 fittings together.
Regularly inspect for wear (>10%), cracks, deformation, heat damage, or corrosion.
