Sling Angle Calculator
Introduction
Calculating the sling angle is crucial in rigging and lifting operations as it directly affects the load’s stability and the forces exerted on the sling. To simplify this process, we can create a user-friendly sling angle calculator. This article will guide you through creating a calculator with precise calculations and a clean interface.
How to Use
Using the sling angle calculator is straightforward. Enter the values for the height and reach of the lift in the provided input fields. Click the “Calculate” button, and the result will display the accurate sling angle.
Formula
The formula to calculate the sling angle is given by:

Where:
- arctan is the arctangent function.
- π is a mathematical constant (approximately 3.14159).
- 180/π converts the result from radians to degrees.
Example Solve
Let’s consider an example where the height is 5 meters and the reach is 8 meters.

After calculating, the sling angle is approximately 32.47 degrees.
