What is the angle between the vertical part of the sling and the part surrounding the load called?

The angle between the vertical part of the sling and the part surrounding the load is referred to as the choke angle. This term specifically describes the configuration of the sling when it is wrapped around a load, creating a lift. In rigging terms, understanding the choke angle is essential because it affects the load distribution and stability during a lift. A choke angle can influence the tension on the sling as well as the overall effectiveness of the lift.

Recognizing this angle is important for ensuring that equipment operates within safety parameters, helping to avoid slippage or failure of the rigging setup during operations. By maintaining an appropriate choke angle, riggers can ensure that their gear is more effective and that the load remains secure throughout the lift.
