What is the definition of working load limit?

• A. A rating for weight handling gear that describes the operational load limits
• B. The maximum weight that can be lifted without assistance
• C. The safe working load for a vessel's hull
• D. The recommended maintenance interval for lifting gear

Answer: (A)

Working load limit is the maximum load that a lifting gear is approved to handle during normal service, as specified by the manufacturer. It’s a rating that accounts for safety and is used to prevent overloading equipment like slings, shackles, hooks, and cranes. This limit helps you choose the right gear for a given lift and plan loads safely, including considering dynamic factors, angles, and shock loads.

The other ideas miss the point: it isn’t the maximum weight you can lift without help, nor a hull’s capacity, nor a maintenance interval.
