How should a shackle and wire rope sling be rigged in a choker configuration?

Rigging a shackle and wire rope sling in a choker configuration requires the correct orientation and attachment to ensure safety and effectiveness during lifting operations. In this case, the correct method involves securing the eye end of the sling to the shackle pin while threading the running end through the shackle body.

This configuration effectively creates a loop that tightens around the load as tension is applied, allowing for a secure grip without slipping. The placement of the eye end on the shackle pin is essential because it provides a stable connection point, allowing the load to be lifted easily. Additionally, this setup minimizes the risk of damaging the sling, as the sling's design is utilized to maximize its gripping capability.

The choker configuration is particularly beneficial when lifting irregularly shaped loads or when the load needs to be secured tightly, preventing it from shifting during the lift. Overall, this method is the industry standard for safe and efficient rigging, thereby ensuring the reliability of the lifting process.
