Which grade is specified for all overhead hooks, chains, swivels, slings?

• A. Grade 7
• B. Grade 8
• C. Grade 6
• D. Grade 9

Answer: (B)

Grading for lifting gear is all about ensuring enough strength for overhead lifting, where loads can be dynamic and shock-prone. Grade 8 is the standard that provides higher tensile strength and better fatigue resistance for overhead hooks, chains, swivels, and slings, so it remains capable under the agreed safe working load and any sudden load surge. This makes it the appropriate, and typically required, choice for all components in an overhead lifting setup. Lower grades would not offer the same reliability under the demanding conditions of overhead lifts, while Grade 9 is not the standard specified in this context. The key idea is that the grade indicates the material’s strength and suitability for overhead work, ensuring the entire lifting system remains coherent and safe.
