How do you calculate the total weight on a sling?

To determine the total weight on a sling, the correct approach involves adding together the weights of all items that the sling is supporting. This method provides an accurate measure of the load being carried, which is essential for ensuring the safety and effectiveness of the lifting operation. Knowing the total weight allows operators to select the appropriate sling type, size, and strength rating, helping to prevent accidents or equipment failure due to overloading.

Estimating based on previous lifts may lead to inaccuracies, as weights can vary significantly between different items or lifting scenarios. Relying solely on the weight rating of the sling does not account for the actual load being supported; instead, it only indicates the maximum weight that the sling can safely handle. Weighing the sling alone provides no useful information about the overall load it will bear during a lift. Therefore, accurately calculating the total weight by summing the weights of all supported items is critical for safe rigging and lifting practices.
