What is a Safety Bow Shackle?
A Safety Bow Shackle — also widely known as an anchor bow shackle, safety pin bow shackle, or bolt-type bow shackle. It is a high-strength lifting and rigging connector featuring a distinctive wide rounded “bow” (O-shaped) body and a secure safety bolt pin system. This design combines the versatile load-handling capabilities of a traditional bow shackle with an enhanced locking mechanism: a threaded bolt secured by a nut and cotter pin (split pin), preventing accidental loosening from vibration, rotation, or dynamic loads.
The safety bow shackle prioritizes maximum security for permanent, high-risk, or vibrating environments. Its broad bow shape provides superior side-loading tolerance and allows multiple sling legs, chains, or ropes to connect without excessive pinching or uneven stress.
- Wide Rounded Bow Design — Enables multi-directional loading, multi-leg sling configurations, and even load distribution.
- Double-Locking Safety Mechanism — The bolt + nut + cotter pin combination ensures the pin stays locked even under heavy vibration, side loads, or prolonged use, dramatically reducing the risk of accidental opening.
- Premium Materials & Durability — Forged from high-grade alloy steel (often hot-dip galvanized for corrosion resistance), built to withstand harsh marine, offshore, construction, mining, and industrial conditions.
- Rigorous Testing & Compliance — Proof-loaded to at least 2× Working Load Limit (WLL) ; marked with size, grade, WLL, and traceability codes to meet international standards like EN 13889, ASME B30.26, or equivalent.
- Versatile Heavy-Duty Applications — Perfect for long-term installations, anchor securing on vessels, heavy machinery lifting, towing, mooring.
Types of Safety Bow Shackles
Screw Pin Bow Shackle
The screw pin bow shackle is the most popular quick-connect option in lifting operations. It features a threaded pin that easily installed and removed by hand or tool.
Therefore, widely used in temporary rigging, construction sites, and general lifting tasks where frequent assembly and disassembly are required. However, it is not recommended for long-term or high-vibration environments, as the pin may loosen over time.
Safety Pin Bow Shackles (Bolt-Type)
The safety pin bow shackle, also known as bolt type bow shackle, designed for maximum security. It uses a bolt, nut, and cotter pin locking system to prevent accidental loosening.
As a result, it is ideal for permanent or semi-permanent installations, especially in marine, offshore, heavy lifting, and industrial rigging applications. Compared with screw pin types, it offers greater reliability under vibration or side loads.
Applications of Bow Shackles
Our anchor bow shackles engineered for secure connections in heavy lifting and demanding rigging environments. Because of their wide bow design and safety bolt system, they are suitable for multi-directional loads and long-term installations. As a result, they are widely used across the following industries:
- Marine & Offshore: Commonly used to secure anchors to ships, barges, and offshore platforms. In addition, hot dip galvanized finishes provide enhanced corrosion resistance, ideal for marine rigging and mooring systems.
- Construction: Used for lifting steel beams, machinery, and precast concrete elements. Moreover, they support multi-leg sling assemblies during crane lifting operations.
- Rigging & Hoisting: Lifting shackles connect slings, chains, and wire ropes in industrial rigging systems.
- Mining & Infrastructure: In mining and infrastructure projects, anchor shackles used for heavy load securing in demanding environments.
