In a choke configuration, slings can effectively handle what fraction of the weight compared to when in a vertical configuration?

In a choke configuration, slings can effectively handle half the weight compared to when they are in a vertical configuration. This reduction in capacity arises due to the geometry and the angle of loading in the choke configuration.

When a sling is used in a vertical configuration, it is aligned directly with the load and can utilize its full rated capacity. However, when the sling is choked around a load, some of the force is distributed away from the direct vertical line, which results in a reduction of the effective load-carrying capacity. In practical terms, this means that the sling must share the load with the other side of the choke point, leading to only half of the sling’s full-rated capacity being usable for the load being lifted or moved. Therefore, it's essential for riggers to be aware of this reduction to ensure safe lifting practices and to avoid overloading the slings.

Understanding this principle is critical in rigging operations, as it impacts not only safety but also the overall efficiency of lifting tasks.
