As a flagship product of the Dutch brand GREENPIN, the G4163 bow shackle—crafted with century‑long artisanal expertise and stringent safety standards—has earned widespread trust in lifting operations across the global heavy‑industry sector. Combining high‑strength materials, a dual‑safety design, and versatile adaptability to diverse applications, it delivers a stable and reliable connection solution for lifting tasks in extreme working conditions.
Core Advantages: Dual Assurance of Safety and Durability
Ultimate strength, solidifying the safety baseline.
Both the body and the pin are made of Grade 6 high-strength steel, subjected to quenching and tempering to deliver exceptional tensile strength and toughness. The product’s minimum breaking load is six times its Working Load Limit (WLL), with a safety factor far exceeding industry standards, ensuring reliable performance under heavy‑load conditions. Additionally, it operates across a wide temperature range of –40°C to +200°C, maintaining stable performance even in extreme cold or high‑temperature environments, thereby eliminating the risk of material embrittlement or deformation.
Dual safety design eliminates potential hazards.
It employs a dual‑safety design featuring bolt pins paired with split pins: the bolts provide primary clamping force, while the split pins effectively prevent loosening or detachment of the pin shaft due to vibration and load misalignment, creating a closed‑loop safety system. The signature green pin‑shaft design facilitates rapid on‑site identification and inspection, enhancing both safety and efficiency in operational workflows.
Anti-corrosion treatment to extend service life.
The surface is hot-dip galvanized to form a dense protective layer, effectively resisting the corrosive effects of marine salt, industrial corrosive gases, and humid environments. This significantly enhances the product’s durability in outdoor and harsh operating conditions, reducing maintenance costs and replacement frequency.
Authoritative Certification: Compliant with Global Industry Standards
The product strictly complies with multiple international standards, ensuring full operational compliance: it meets EN 13889 (for capacities ranging from 0.5 to 25 tonnes), satisfies the U.S. Federal Specification RR‑C‑271, Type IVA, Class 2, Performance Level A requirements, and, for capacities of 2 tonnes and above, additionally conforms to ASME B30.26. Furthermore, it has been certified by globally recognized classification societies and authorities, including DNV GL 2.7‑1, DNV GL 0378, and ABS. Upon request, we can provide a complete set of certification documents, such as material certificates (2.1 and 3.1) and DOC certificates, to align with the regulatory requirements of diverse regions worldwide.
Specifications: Full-range coverage to meet diverse needs.
The product is available in a full range of capacities, from 0.5 to 85 tons, enabling precise alignment with lifting requirements across diverse load scenarios. Each size is manufactured with high precision, featuring tightly controlled dimensional tolerances to ensure seamless compatibility with slings, hooks, and other accessories, thereby enhancing connection stability. Key specification parameters are listed below; complete specifications can be obtained upon request via CAD drawings and data sheets.
