Note:

This calculator is used to determine the tension per leg of a lifting sling. Accurate tension calculations are essential for safe lifting operations, preventing overloading and ensuring the correct sling type is used. It helps in selecting the appropriate lifting equipment and minimizes the risk of accidents, equipment failure, and workplace hazards.

The calculation is based on several key factors that influence the tension in each sling leg:

• Total Load (W): The overall weight of the object being lifted, measured in kilograms. This includes the weight of the load itself and any additional forces acting on it.
• Sling Length (L): The length of each individual sling leg, measured in meters. A longer sling affects the load distribution and lifting angle.
• Number of Legs (N): The total number of sling legs supporting the load. More sling legs generally help distribute the load more evenly, reducing individual leg tension.
• Vertical Height (H): The height from the lifting point to the load, measured in meters. A shorter vertical height increases the angle of the sling, leading to higher tension in each leg.

Understanding these factors ensures that the appropriate lifting configuration is used, reducing stress on the sling and improving operational safety. A proper tension calculation prevents exceeding the Working Load Limit (WLL) of slings, which can lead to dangerous failures.

The calculated **tension per leg** helps in determining the appropriate sling rating required for a safe lift. If the tension exceeds the Working Load Limit (WLL) of the selected sling, adjustments must be made, such as increasing the number of legs, using longer slings, or reducing the total load. Proper load distribution and correct sling selection are critical to preventing failures and ensuring a safe lifting operation.
