For the most critical, high-stakes lifting and mooring operations, the standard screw pin shackle is not enough. Introducing the Bolt Type Omega Anchor Shackle, engineered for permanent or semi-permanent applications where supreme security and unparalleled strength are non-negotiable. With a massive Working Load Limit (WLL) range from 0.5 to 250 tons, this shackle is the trusted connection point for heavy industries across New Zealand's ports, Europe's offshore wind farms, and North America's major infrastructure projects.
The Bolt-Type (or Anchor-Type) design is fundamentally different. Instead of a hand-tightened screw pin, it uses a robust bolt, nut, and cotter pin assembly, creating a captive, vibration-proof connection that cannot unscrew accidentally.
Patented Cotter Pin & Collar System: Our design goes beyond a standard bolt. We employ a high-tensile steel bolt, a self-locking crown nut, and a positive-locking cotter pin with a machined safety collar. This triple-assembly ensures the pin remains securely in place, even under extreme vibration or shock loading, effectively eliminating the risk of accidental disassembly.
Omega Bow Design with Optimized Profile: The "Omega" nomenclature reflects our bow's unique, smooth, and continuous geometry. Unlike traditional designs, this profile minimizes stress concentration at the crown and pin holes, distributing load more efficiently. This increases the shackle's fatigue life by up to 20% when used with wire rope or synthetic slings.
Forged from Grade 8 Alloy Steel: We use a premium Grade 8 (or equivalent 800MPa) alloy steel, subjected to a precise computer-controlled heat treatment. This ensures an optimal balance of ultimate tensile strength and impact toughness, making it suitable for dynamic lifting and harsh offshore environments.
Ultrasonic Cleaning & Penetrating Coating: Prior to galvanizing, each shackle undergoes ultrasonic cleaning to remove all forging scale and contaminants. This ensures the subsequent hot-dip galvanized coating adheres perfectly, with no weak points for corrosion to begin, significantly extending service life in saline or corrosive atmospheres.
Absolute Pin Security: The bolted assembly is the safest option for long-term, vibrating, or inverted applications, providing peace of mind that a screw pin simply cannot.
Extended Service Life in Harsh Conditions: The superior Grade 8 material, optimized Omega bow design, and flawless corrosion protection combine to offer a significantly longer operational life, reducing your total cost of ownership.
Global Compliance for High-Risk Industries: Manufactured to exceed the most rigorous international standards, including EN 13889, ASME B30.26, and Lloyd's Register for marine use, ensuring acceptance on any global project site.
