Grade 100 Container Lifting Clevis Link CLK Type

No.505012

The Grade 100 Container Lifting Clevis Link (CLK Type) is a specialized coupling component designed specifically for connecting the chain elements required in container handling operations.

  • Secure Locking System: Features a spring locking pin that enhances security and prevents chains from accidentally disengaging during container lifts.
  • Grade 100 Strength: Approximately 25% stronger than Grade 80, with a 4:1 safety factor and proof load of 2.5 times the WLL.
  • Rigorous Testing: 100% Magnaflux crack detection performed on every unit.
  • Standard Compliance: Manufactured from quenched and tempered forged alloy steel to EN 1677, with a powder-coated surface finish.

Product Features

  • Secure Locking System: Unlike standard container hooks that can fall out when the lifting line goes slack, the CLK Type features a spring-loaded Safety Locking Pin. This ensures the hook stays positively engaged in the container corner casting at all times.
  • Grade 100 Performance: Manufactured from high-strength G100 alloy steel, providing a 25% higher Working Load Limit than G80 equivalents. This allows for lighter chain slings without sacrificing capacity.
  • Direct Clevis Connection: Designed with an integral clevis pin to attach directly to Grade 100 chain. Eliminates the need for a connecting link, reducing the overall weight and "headroom" of the rigging assembly.
  • ISO Container Compatibility: Specifically shaped to fit standard ISO Container Corner Castings (Left & Right or Universal depending on specific design geometry). Ideal for side-lifting loaded or empty containers.
  • Durability: Quenched and tempered alloy steel construction with a durable powder-coated finish for corrosion resistance.
  • Standard: Compliant with EN 1677 and Grade 100 safety standards.

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.
