Proper Rigging Techniques...Have You Ever Done This When Rigging?

Picture this: You’re connecting a sling to a swivel hoist ring using a screw pin shackle.  You get the sling nestled nice and comfy in the bow of the shackle and put the ears around the bail of the hoist ring.  You insert the shackle pin through the ears of the shackle (being careful to catch the bail on the way through) and you twist it until it’s tight against the side of the shackle.  You’re about to fly the load but wait, you forgot something! A supervisor told you that the pin is supposed to be backed off 1/4th of a turn! How could you have forgotten?!


If you’ve ever been in this situation before, we have some news for you.  The American Society of Mechanical Engineers states quite plainly in its B30.26 standard for Rigging Hardware “screw pin threads shall be fully engaged and tight, and the shoulder should be in contact with the shackle body” prior to any lift.


With rigging especially, there seems to be a lot of industry practices that came about without consulting the manufacturer and this is one of the many examples we cover in our Crosby Rigging Seminars.  One of our trainers goals during the training is to point out where there are no grey areas; if the manufacturer of a product has written procedures for its use and we don’t follow them then who is being negligent?  Proper rigging techniques should always be used to avoid accidents and injuries.


If you’re now wondering if there are any other rigging situations or practices that might not be up to par, please don’t hesitate to contact our professional Safety Trainers.
