As a leading manufacturer established in 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-quality offshore oil rigging equipment. Our Offshore Oil Rigging Equipment - Corrosion Resistant, 50 Ton SWL Shackles and Hooks are engineered to withstand the harshest marine environments, ensuring reliable performance and long service life. With annual export values reaching US$5-10 million and a global presence across North America, South America, Europe, and Asia, we bring decades of expertise to every product we deliver.
These shackles and hooks are designed specifically for offshore oil drilling applications where safety, durability, and corrosion resistance are paramount. Each component is manufactured from high-strength alloy steel and undergoes rigorous quality control processes to meet strict industry demands. The 50-ton Safe Working Load (SWL) rating ensures dependable lifting capacity for heavy offshore equipment, while the specialized corrosion-resistant coating protects against saltwater, humidity, and chemical exposure.
Key Features and Benefits:
- Superior Corrosion Resistance: Hot-dip galvanized or optional epoxy coating provides exceptional protection against marine corrosion, extending service life in offshore environments.
- High Strength & Durability: Forged from premium alloy steel with heat treatment, achieving minimum breaking strength far exceeding SWL requirements.
- Precision Engineering: CNC-machined pins and matching bores ensure smooth operation and secure locking under load.
- Safety Compliance: Each unit is proof-loaded and magnetic particle inspected to verify integrity, with traceable serial numbers.
- Versatile Design: Available in screw pin, bolt type, or round pin shackle configurations, and eye or clevis hooks to suit various rigging systems.
- Easy Installation: Standardized dimensions compatible with common offshore lifting hardware, reducing downtime during replacement.

Frequently Asked Questions (FAQs):
-
Q: What materials are used in your shackles and hooks?
A: We use high-strength alloy steel grades such as 20Mn2 and 40Cr, which are heat-treated to achieve optimal mechanical properties. The exact material can be specified upon request. -
Q: How do you ensure corrosion resistance for offshore use?
A: Our standard surface treatment is hot-dip galvanizing with a minimum coating thickness of 85 microns. For additional protection, we can apply epoxy or other specialized coatings. All products are salt spray tested. -
Q: Do you provide load testing certificates?
A: Yes, each unit comes with a proof load certificate. We can also arrange third-party inspection and certification from organizations like Lloyds, DNV, or ABS at an additional cost. -
Q: Can the shackle pin diameter be customized?
A: Absolutely. We offer custom pin diameters, lengths, and thread types to match your lifting hardware. Minimum order quantities may apply. -
Q: What is the delivery time for standard products?
A: For standard 50-ton SWL shackles and hooks, we typically ship within 15-25 working days after order confirmation, depending on quantity. -
Q: Are these products suitable for dynamic lifting?
A: Yes, our shackles and hooks are designed for both static and dynamic lifting applications. However, we recommend consulting our engineering team for specific dynamic load factors. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is 50 pieces per size for standard items. For custom orders, MOQ may vary. Please contact us for details. -
Q: How do you package the products for export?
A: We use sturdy wooden crates or steel pallets with individual protective wrapping to prevent corrosion during transit. Each crate is marked with weight, size, and handling instructions.
