Green Pin® PRODUCTS

Green Pin is a leading global name in high-performance lifting equipment, primarily known for its shackles, turnbuckles, and lifting components. These products derive their superior strength and resistance from three critical, interconnected design elements:

• The Forging Process.
  At the foundational level, Green Pin components begin as high-grade steel that undergoes a specialized forging process. This isn’t simple casting; it’s a shaping process involving compressive forces:

  • Grain Structure Alignment: Forging refines and aligns the internal grain structure of the steel, making the final product less susceptible to fatigue and micro-fractures under cyclical loading.

  • Elimination of Voids: The intense pressure virtually eliminates internal voids or defects, resulting in a steel body with maximum density and uniform strength across the entire piece.

  • Result: This initial step creates the bulk strength and core integrity necessary to handle extreme working loads.

• The Pin-Body Interface (The Load-Bearing System).The “shackle” itself is a two-part system designed for optimal load distribution. The synergy between the body (bow) and the pin is what creates exceptional resistance:

  • The Body (Bow): The U-shaped or ‘bow’ section is designed to distribute the load across a large cross-sectional area. Its shape prevents localized stress points, managing forces that would otherwise cause bending or breaking.

  • The Pin: This removable component (either screw pin or safety bolt) acts as the connection point. It’s often subjected to heat treatment to enhance its surface hardness and core toughness, making it highly resistant to shear forces and wear.

  • Assembly: When the pin is secured, it locks the system into a single, cohesive unit, ensuring the load is borne and distributed efficiently throughout both components.

• Traceability and Certification (The Assurance Core).
  In the world of lifting, resistance isn’t just physical—it’s certified and guaranteed. The core assurance of a Green Pin product lies in its rigorous quality control:

  • Material Grading: Only certified, high-tensile steel grades are used, ensuring predictable yield and breaking strength (e.g., Grade 8 or DNV certification).

  • Marking: Every major component features permanent traceability markings (like a batch number, Working Load Limit (WLL), and size). This ensures that the material, testing, and production history can be instantly verified.

  • Application: Green Pin products are essential components in heavy-duty applications, including marine towing, offshore oil & gas, construction rigging, and industrial material handling. They represent the benchmark for reliable, certified resistance in the global lifting industry.
