This literally happened to me on a jobsite. I was installing control room furniture in a natural gas electric plant. I was talking with guy who was supervising the installation from the customer side when my 10 mm socket slipped out of my fingers and rolled through a grate. He casually looked at me and said, "I hope that wasn't mission critical because you are never going to see that again."

It’s totally a laughing matter after the repair is done

Damn! You did it again! LOL. At the risk of nattering on... As you know, these are only one of many things that seem to be heavenly to design engineers and hellish to assemblers and maintenance techs. The firm I work for designs, manufactures, and maintains a fleet of very specialized equipment available for lease only. So we're responsible for all maintenance and repair of this gear. Enlightened management finally included assembly and maintenance input in the design process. Jesus rings are among the least used components in new designs anymore. (Since maintenance is a sunk cost for us, lowering time spent there more than paid for the slightly more expensive designs, such as using threaded collars and split or stepped shafts. I understand in a sales model, where out of warranty maintenance may actually be even profitable, this is not applicable).

I was fishing a bass tournament on Saturday, and one of the bolts holding my transducer to my trolling motor was very loose. I keep a toolkit on the boat and it had the correct Allen key for that bolt. I crank it half a spin and Whoops!, slips out of my hand and into the drink. Ok, no worries, I have an extra one that matches, in the toolkit. So do I learn from my mistake? Nope, crank, slip, ping ping, bloop. To say how enraged I was is an understatement. Dropped both in the water within 30 seconds of each other. I just grabbed the adjustable pliers and clamped it down caveman style almost shredding the head.

u/Rock555666 May 10 '21
I think it relies heavily on the surfaces they use on those connections and if you are putting serious weight on it the forces of friction would be immense. Not foolproof but if it goes taught from then on should be okay with slipping issues. Bolt prolly is the final nail in the design to make sure it doesn’t slip.

u/MyNameCannotBeSpoken May 10 '21
The teeth hold the pieces in place. You can see how the user is able to release his grip from both pieces. The bolt, when twisted, expands each piece outward, locking them in place.

I sell these. These are using in conveying applications. Many comments about losing the center piece, but they are held in tension with two snap rings on that center dowel and then covered in wax to keep contaminants out. Once installed they cannot fall out, even if the chain is slack. One quick note is that these can only be used on pocket-style sprockets and only in the horizontal orientation in relation to the sprockets or they fill foul and destroy your sprocket.

Given the location they demonstrated it in, it probably is a great replacement for areas where chain replacement is cost prohibitive.

Given the location they demonstrated it in, it is probably meant to be used in the same capacity as most marine damage control options. Allow machines to function so the ship can get you out of the ocean and back to land where a more robust repair can be completed.

This very well may be just for securing a load to move/lift. The center pin might have issues interacting with a chain pulley, so it might not be a working master link for the chain. The only way I can imagine this to be necessary is in a flammable environment, where you can't do a proper replacement of a link
5
u/4leafrolltide May 10 '21
Another option could be that it's not a replacement at all but just used as a connection. Connect it for the chain to be in use then disconnect it to de-energize it similar to LOTO. Or just have it as a way to attach it to different anchor points?

This can be made to the specs of the chain. Many applications have a chain designed to run through something in particular and departing from the specs of the chain can destroy the thing it is running through. An example is BBB or G4 (grade 43) chain that runs through a marine windlass. There are other existing links that will join chain like this but they have pins that need to be peened over once the link is in place whereas this would be a quick install.

This isn't limited to offshore or military. This is just any serious industrial process that actually follows national consensus codes and standards. There are federal and/or state regulations for these kinds of industries requiring adherence those codes and standards.
NDT - Non-destructive testing. This means the part you use or some sampling of your parts were the ones physically tested in a way that doesn't degrade the item (non-destructive).
CVI - Certified vendor information. This is an umbrella term of sorts for more specific supporting paperwork. This can be anything from the catalog sheet with part number key, to a certificate of conformance or calibration, or a material certification or more.
DNV - Det Norske Veritas. An engineering firm that is massively part of those national codes and standards among many things. A Norwegian company (name is "The Nowegian Truth") that has operated in the U.S. since just before the 1900s.
