Enter the sling angle in degrees into the calculator to determine the sling angle factor. This factor is used to calculate the actual load on a sling when it is not vertical.
Sling Angle Factor Formula
The following formula is used to calculate the sling angle factor:
SAF = 1 / cos(θ)
Variables:
- SAF is the sling angle factor
- θ is the sling angle in degrees
To calculate the sling angle factor, divide 1 by the cosine of the sling angle in degrees.
What is a Sling Angle Factor?
The sling angle factor is a multiplier used to determine the increased load on a sling when it is used at an angle rather than vertically. As the angle of the sling decreases from 90 degrees (vertical), the load on each leg of the sling increases. The sling angle factor is critical for ensuring the safety and integrity of lifting operations.
How to Calculate Sling Angle Factor?
The following steps outline how to calculate the Sling Angle Factor.
- First, determine the sling angle (θ) in degrees.
- Next, use the formula SAF = 1 / cos(θ).
- Finally, calculate the Sling Angle Factor (SAF).
- After inserting the variable and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variable as an example problem to test your knowledge.
Sling angle (θ) = 30 degrees
