When using a shackle in a choker configuration, how should it be rigged?

Using a shackle in a choker configuration requires careful attention to how the sling is connected to ensure safety and effective load handling. The correct rigging method involves connecting the eye end of the sling to the shackle pin, while allowing the running end of the sling to pass through the shackle body. This configuration creates a secure choke that tightens around the load as it’s lifted, enhancing stability and control during lifting operations.

When the eye end of the sling is attached to the shackle pin, it naturally aligns with the load and allows the running end to create the necessary choke effect. As the load is lifted, the sling tightens, preventing slippage and ensuring that the sling and load remain in the desired position during the lift.

Other methods, such as connecting both ends of the sling to the shackle or using the center of the sling, may not provide the appropriate tension and control needed for a choker. Similarly, attaching the running end through the shackle while not securing the eye end correctly could lead to a loss of load or instability during lifting. The precise configuration outlined by the correct answer optimally utilizes the properties of the shackle and sling, leading to a safer rigging setup.
