Grade 80 Sliding Choke Hook – High-Strength, Self-Tightening Lifting Solution

Key Features:

• Grade 80 Alloy Steel Construction: Heat-treated to meet ASTM A342 standards, delivering a minimum tensile strength of 800 N/mm² (116,000 psi) and a 4:1 safety factor—certified for overhead lifting.
• Sliding Choke Mechanism: The hook slides into position and tightens around the chain or sling under load, creating a secure, non-slip connection that resists disengagement.
• Smooth, Rounded Profile: Minimizes wear on chains and synthetic slings during use and ensures smooth operation.
• Permanent Markings: Clearly stamped with Working Load Limit (WLL), size, Grade 80 designation, and manufacturer ID for traceability and compliance.
• Durable Finish: Typically coated in red or yellow powder paint for high visibility and corrosion resistance.

Common Applications:

• Securing chain slings in vertical or basket hitches
• Lifting cylindrical or irregular loads that require a self-tightening grip
• Transport and recovery operations in construction, oil & gas, and mining
• Multi-leg sling assemblies where dynamic load adjustment is needed

Safety Recommendations:

• Use only with other Grade 80 components to maintain system integrity.
• Never exceed the marked WLL.
• Inspect before each use—retire immediately if cracks, deformation, or throat wear are detected.
• Intended for in-line (axial) lifting only—side loading is strictly prohibited.

Engineered for intelligent load control—the Grade 80 Sliding Choke Hook delivers hands-free security and trusted performance in every critical lift.
