What is the formula for SWL of heavily used rope?

• A. BS ÷ 4
• B. BS ÷ 6
• C. BS ÷ 8
• D. BS ÷ 10

Answer: (C)

The formula for the Safe Working Load (SWL) of heavily used rope is derived from the Breaking Strength (BS) of the rope. In the case of heavily used rope, it is generally accepted to divide the Breaking Strength by a factor of 8. This safety factor accounts for wear, environmental conditions, and the impact of dynamic loads that the rope may experience during operations. By using a division factor of 8, you ensure a margin of safety that recognizes the decreased integrity of the rope due to regular use and potential fatigue. This provides a more conservative and safe working load limit compared to using higher factors, which might not adequately reflect the condition of the rope after repeated uses. Properly calculating SWL is crucial for maintaining safety and preventing accidents in handling operations.
