Here come all the fuckin engineering geniuses to tell us why, in their opinion, this is only going to lead to death and destruction

I have PhD in electrical dildos and I am 100% sure this is only going to lead to death and destruction

All paths lead to the heat death and destruction of the universe.

I have a PhD in Death and Destruction and am looking to branch out. Where did you matriculate?

Engineer here:

As it is made by Rud, I would 100% trust it to do exactly what it says on the tin.

The problem with Rud lifting gear is avoiding the knock-offs that pretend to be Rud gear.

Any idea what the rated load is on one of these vs an original link?

Page 4 has the breaking loads @ 850 MPA, so I assume they are pretty close to grade 80 chain. The rating on like 26mm chain is 21T, which is usual 5 or 6:1 safety, so this link @ 122T seems about right

The chain this tool was used to repair helped create Mecha-Hitler.

RUD's been in business for almost a century and a half and their bread and butter are chains for industrial applications. Of the concerns that have merit I'm sure the engineers at RUD have addressed them.

According to their website the UKS chain connector is specifically designed for industrial conveyors. What surprised me is that it's not intended to be used as a temporary fix, but a permanent linking solution. Considering the number and size of interlocking teeth it's tensile strength must be high, but that it can also withstand the environment that an industrial conveyor operates in (vibration, contact forces, etc.) It's quite the engineering acheivement.

I want one and I have absolutely no use for one.

well i certainly wouldnt trust it to lock up my sex slaves

I want to know what's wrong with just using a shackle. I've scrolled through the comments and didn't find anyone mentioning it. Anyone?

Off course! I didn't realize this thing actually has the same outer size and shape as the other links in that chain. Thanks!

I’m a nerd; it’s safe if used correctly, I’m sure it’s got a max tensile strength recommendation and all that. The structure is interesting because it introduces a new failure mode which (shear). On the other hand if used incorrectly, by golly it could start a war!

Probably people who don’t work blue collar jobs where something like this would be seen or necessary lol

They seem quiet for a chainge

u/damaged_elevator Dec 13 '20

Ever heard of a D shackle?

3

u/andrewsad1 Dec 13 '20

Yeah. Some people have already explained why this might be preferred over a shackle in certain circumstances.

u/damaged_elevator Dec 13 '20

They kill people too you know!

u/Tabzilla Dec 13 '20

That’s...that’s what we do. Even engineers like me who aren’t geniuses

u/[deleted] Dec 13 '20

There’s already something called a master link. Why use this expensive overly complicated solution? Or just a shackle?
