Chain Slings must use only which grade range?

• A. Grade 60-80
• B. Grade 40-60
• C. Grade 80-100
• D. Grade 100-120

Answer: (C)

Chain slings rely on the chain’s grade to determine how much load they can safely carry. The grade range 80 through 100 is specified because it provides high-strength, durable chain suitable for most lifting tasks and for calculating safe working loads with standard fittings. Lower grades such as 40-60 or 60-80 aren’t strong enough for typical lifts and would risk chain failure. Higher grades like 100-120 exist, but the commonly used range for chain slings is 80-100, balancing strength, availability, and cost.
