What term is defined as the maximum load that should ever be applied to a chain?

• A. Working Load Limit
• B. Breaking Strength
• C. Ultimate Load
• D. Tensile Capacity

Answer: (A)

The maximum load you should apply to a chain in service is the Working Load Limit. This value is the safe operating limit that accounts for real-world factors like shock, dynamic loads, misalignment, wear, and corrosion. It’s set well below the chain’s rated strength so there’s a built-in margin for unexpected conditions, protecting both people and equipment.

For context, breaking strength is the force at which the chain would fail in a test, and ultimate or maximum load describes the point of rupture, which you should not approach in normal use. Tensile capacity refers to the chain’s overall strength, but it’s not the recommended safe working load for everyday operations. The working load limit represents the practical, safe limit used in daily rigging and lifting work.
