Final answer:
Using two rigging slings in this manner helps to evenly distribute the weight, provide additional support and stability, and prevent the bundle from shifting or sliding during lifting.
Step-by-step explanation:
The purpose of using two rigging slings that are double wrapped and chocked, with one chocker placed about 5ft from each end of the bundle, is to achieve multiple objectives:
- To evenly distribute the weight of the bundle: By using two slings, the weight of the bundle is divided equally between them, ensuring that neither sling bears an excessive load.
- To provide additional support and stability to the bundle: Having two slings wrapped around the bundle increases the contact area and provides extra support, reducing the risk of the bundle shifting or becoming unstable during lifting.
- To prevent the bundle from shifting or sliding during lifting: By chocking the slings at specific points along the bundle, the slings work as anchors, preventing the bundle from sliding or shifting during the lifting process.
