What is the minimum recommended sling angle?

The minimum recommended sling angle is 30 degrees because this angle helps balance the distribution of forces within the rigging system and provides optimal lifting stability. At this angle, the tension in the sling is minimized while maintaining a safe working load limit. Angles that are too low can increase the stress on the rigging components, risk sling failure, and lead to less stability during the lift, whereas angles that are too high may not effectively distribute the load.

A 30-degree angle strikes a balance between the need for securing the load and reducing the risk of slippage or tipping during elevation. Thus, ensuring that riggers maintain this minimum angle helps to enhance safety and efficacy in lifting operations.
