Great informative video, it will save lives if procedure is followed.

The angle that the hooks are pulling off the shackles is wrong. I know this is unavoidable due to where the holes are made, but it should be mentioned. You're pulling the shackle from 1 side, creating a single shear pin point of pressure. Shackles are designed to lift to double shear, where the load is evenly balanced across the middle of the pin, but a lot of people don't know that and think it doesn't make any difference if the shackle is in line or not.

Thanks for your comment. Anchor style shackles can be side loaded per ASME B20.26 as long as you take the proper reductions. Please watch our shackle webinar for information on use of shackles: owl.li/svJ05 and let us know if you have any further questions. Regards, Peter Cooke

Columbus McKinnon Booyeah!

The shackles bow which should bear the load not the bolt.

Hello Slimane, can you please explain your question further? We are a bit confused as to what you are asking. Many thanks!

Four slings attached to one master link its a nooooooo go.

[@columbusmckinnon]

Hi Domingos, Attaching four slings to a single masterlink is known as a quad sling. The attachment point can be made with welded couplers or mechanical couplers/Hammerloks. The use and manufacture of these types of slings has been around for years and is widely acceptable. Additional information can be found OSHA 1910.189 Slings & ASME B30.9. When using this type of sling, the working load limit is calculated the same as a triple. So the load charts for each triple and quad will be equal for the size of the chain used to make the sling. If you have any questions feel free to contact us. Henry Brozyna

Hey Columbus. The use of four slings attached to a single master link is not a recommended practice in the UK or in EU for the fact that: in one master link the two slings in the outside will be overloaded because they seat higher in the master link check for yourself that the two slings in the centre are longer than the outer ones. Hence the recommended practice is max allowed slings in one master link is two and if you need to connect three or four you shall use a master link with two sub master links.
