Key Concepts

• Importance of working with limitations in sling load calculations.
• Risks involved: property damage, serious injury, etc.
• "Working with limit" refers to the carrying capacity which is less than the breaking strength of a sling.

First Example: Single Sling

• Scenario: Sling oriented at an angle to the horizontal.
• Objective: Determine tension on the sling.
• Calculation:
  • Tension = Weight of Load / Number of Slings.
  • Example: 1,000 lbs load with 1 sling results in 1,000 lbs tension on the sling.
• Conclusion: Sling should have a working limit of at least 1,000 lbs.

Safety and Design Factor

• Consider design factors which may affect sling performance.
• Breaking strength calculation: Multiply sling tension or working load by a safety factor (at least 5 for new materials).

Second Example: Double Sling

• Scenario: Two slings at a 30-degree angle to the horizontal.
• Objective: Calculate tension on each sling.
• Calculation:
  • For a 1,000 lbs load with 2 slings, tension is 500 lbs per sling.
  • Working limit must be at least 500 lbs multiplied by a design factor of 5.
• Conclusion: Breaking strength of at least 2,500 lbs required.

Choosing the Right Sling

• Ensure sling is marked for breaking strength or ultimate strength.
• Select slings according to the required working load limit.

Conclusion

• This video provides foundational understanding for future topics on calculating tension with different tools and conditions.
• Future discussion topics include calculations involving vertical sling positions.
