What is the maximum angle for lifting with slings before it compromises safety?

The correct response highlights that lifting at angles exceeding 60 degrees can significantly increase the load on the slings, potentially compromising safety. When slings are used to lift loads, the angle at which they are set has a critical impact on the forces acting on them.

As the angle between the sling and the load increases, the tension in the sling increases, leading to greater force exerted on the rigging equipment. At an angle beyond 60 degrees, this can mean that the load supported by the sling effectively doubles, putting substantial stress on the sling material and the rigging system. This increased tension raises the risk of equipment failure or accidents, emphasizing the importance of adhering to safe rigging practices.

Understanding the mechanics of this principle helps in maintaining safety in lifting operations. Therefore, recognizing that angles above 60 degrees can lead to doubled load tension reminds operators to be vigilant in their rigging configurations.
