When a load has no attachment points pr when the attachment points exist not practical for lifting, it is best to utilize a Choker hitch .
<h3>
What is Choker hitch?</h3>
To secure or cinch a sling down tightly and offer better load control, use a choker hitch. When employing a choker hitch, the weight is wrapped around one eye of the hitch, which is then threaded through itself and fastened to the crane or hoist hook.
While being raised, a load's sling becomes more snug. Never apply to loose bundles. Use choker hitches with a rated sling capacity of no more than 75%. Use slings that are long enough for the choker hitch to work and for the webbing to act as the "grip."
The load is only compressed from three sides when using a typical choker hitch. Use a double wrap choker hitch and two slings for lengthy weights for a superior method of performing the same lift. The double wrap significantly improves load control by compressing the weight from all four sides.
Hence, When a load has no attachment points pr when the attachment points exist not practical for lifting, it is best to utilize a Choker hitch.
