Sling Angle Factor Calculator

Formula

To calculate the Sling Angle Factor (SAF):

\[ SAF = \frac{1}{\cos(\theta)} \]

Where:

\(SAF\) is the Sling Angle Factor
\(\theta\) is 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.

Example Calculation 1

Let's assume the following value:

Sling Angle (\(\theta\)) = 30 degrees

Using the formula:

\[ SAF = \frac{1}{\cos(30^\circ)} \approx 1.15 \]

The Sling Angle Factor is approximately 1.15.

Example Calculation 2

Let's assume the following value:

Sling Angle (\(\theta\)) = 45 degrees

Using the formula:

\[ SAF = \frac{1}{\cos(45^\circ)} \approx 1.41 \]

The Sling Angle Factor is approximately 1.41.
