Grade 80 Clevis Winged Grab Hooks
High-Strength Components for Secure Chain Adjustments
Grade 80 Alloy Steel Winged / Cradle Design Clevis Pin Attachment
A Grade 80 Clevis Winged Grab Hook (also known as a cradle grab hook) is a high-strength lifting and rigging component explicitly engineered for securing, shortening, and adjusting lifting chains in heavy-duty applications. Its unique geometry ensures maximum grip while maintaining the structural integrity of the chain link.
Design & Engineering Features
⚒️
Grade 80 Alloy
Forged from premium Grade 80 heat-treated alloy steel, providing exceptionally high tensile strength and maximum durability for overhead lifting and critical load securement.
🔗
Clevis Style Fitting
Features a secure clevis pin attachment. This allows for fast, easy, and direct connection to chain links or other rigging hardware without the need for additional coupling links.
🛡️
Winged (Cradle) Design
The specialized "wings" create a cradle that supports the chain link. This crucial design helps prevent the chain from slipping sideways out of the hook, making it vastly more secure.
⚓
True Grab Functionality
Precision engineered with a narrow throat opening designed to grab and securely hold a specific chain link in place without slipping, perfect for precise length adjustment.
Industry Applications
- Chain Shortening: The primary tool for safely adjusting the leg length of chain slings to balance asymmetrical loads.
- Load Securement: Heavily relied upon in transportation, heavy-duty towing, and tie-down applications.
- Versatile Rigging: Essential hardware in construction, material handling, and multi-leg lifting sling assemblies.
Safety & Load Standards
- WLL Variations: The Working Load Limit (WLL) varies strictly by the specific size and diameter of the chain being used.
- Compliance: Manufactured and rigorously tested to meet global safety standards, including EN 1677, OSHA, and ASME B30.9.
- Legibility: Must be clearly embossed with the grade (G80/8), manufacturer mark, and relevant size parameters.
⚠️ Critical Rigging Warning: Side-Loading Prohibited
Grab hooks are strictly designed for straight-line, inline tension. They are absolutely NOT designed for side-loading, tip-loading, or back-loading. Subjecting a grab hook to improper angles forces the load onto the weakest parts of the casting, which can quickly lead to catastrophic failure.
