I don't normally comment on these videos, but I've been inspecting and repairing rigging equipment such as chain hoists for many years and noticed a few issues which may be serious safety concerns for anyone using this video as a guide to the inner workings of hoists and feel I have an obligation to say something. Hoists of this vintage are interesting as devices in their own right, but should not be put into service due to both the potential metal fatigue issues arising from long use and the fact that they don't meet current standards. As for the assembly, the welding of the chain and greasing of the friction disks have already been mentioned repeatedly in the comments, but what I didn't see mentioned is the top hook; it doesn't match the lower hook and I don't think it belongs on this hoist. It looks like a tow-hook from a jeep or truck that somebody used to jerry-rig the hoist for use. These may be different grades of steel, with the hook not being rated for lifting use. If I saw this come through my shop it would be an immediate fail. This hoist makes an interesting display piece, but has no place in any shop.
The reason the chain is welded around the lower sheave block is a Gerry-rigged hack to make the lifting distance 2 X of what it was originally designed. Some hoists are designed that way however, the single chain is connected directly to the hook and not welded around the sheave wheel, In addition, the hoist's lift rate is derated by 50%. Everything the fellow said above is 100% correct.
I want to thank you for not editing out the mistakes. It makes it real to me. Because those things are exactly what happens to me when I fix things. Take it back apart three times to put something in I forgot, it makes me not feel like an idiot. Keep doing your thing. You do good work
Nice! I have the same chain pully. It’s actually not supposed to be welded around the bottom pully, it’s supposed to go back up to be a second block. It’s a very slow chain hoist but with the pully system it can lift a lot of weight.
Really enjoyed this resto, reminded me of the days we use play with Mechano sets! Very happy that you didn't change the chain!! I remember my dad use to put rust and grease covered stuff in either diesel or petrol, use to work like a charm!! Keep them coming!!
Love you too AJ. This was really satisfying to watch. Especially the chains in the Acid. Also what I’m liking more and more is the latch open on the sandblaster with the swinging door. Gotta love it.
I've got one similar to this that my Dad and I used to remove and replace car engines with. Ours was at one time used by Pan Am to remove and replace the old radial reciprocating engines.
Dear Vintage Manual Chain Hoist Restoration, hi. Artistic. AMAZING, bro. I loved your work. CONGRATULATIONS. Thanks a lot. Gracias. Happy New Year, Happy 2022. Marcelo Baglione from Brazil, Rio de Janeiro, Rio
Agree to disagree Gregg. She has proved that our votes don't count. We the people voted on a measure it passed and she said she will not allow it to happen.
Your chain fall is in an unsafe condition. The welded loop you put through the pulley is an unsafe alteration. The chain should go through the pulley and back up to the gear box.
I just found your channel via a Facebook DIY crafts video showing highlights of this restoration. Not a bad job here for the mechanical stuff. But the lifting chain with the weld in it is a bad idea. I work in industrial lifting and we would fail that with no hesitation. But for a cosmetic piece, it's fine. Going to subscribe, love seeing the complex mechanical stuff done up properly. Keep it up.
i worked at a company for 15 years and repaired all kinds of chain hoists. The one thing that almost always needed replaced were the hooks because the safety latch was bent or missing. the hook was unsafe.
Harold, with you 100%. I was 37yrs in the lifting industry. The hook is of a 4 x 4 tow hitch and the chain is welded back to itself on the bottom hook. The chain should come back up to a main part of the block and terminate giving a 2 part fall. Also the gears in the back were not timed to there settings if he lifts to much they will break and the load will drop. If it all holds together it might make 500kg WLL On the up side AJ did do a nice job on restoring it, looks good and I'll have to check his other videos
If you do decide to fix the chain, would you please make a video of it so that anyone who wants to refurbish one of their own, would be able to refer to your fix as a guideline?
Looks great!! Looks like it might have been a pain to take apart and put back together. How many times did you have to look at the video to put it together again?? LOL They last forever!! Enjoyed your video and I gave it a Thumbs Up
nice job .. BUT when you powder coated the hooks and other metal to metal pieces you should have either cold blued them or heated them and quenched them in oil to make them black... the powder coating will not last and will chip off during use and rust will again happen oil quenching or bluing will stop this from happening. just somthing to think about for future projects.
Heating up the metal parts to oil quench bluing temperature is a definite no-no as this is hot enough to change the temper/heat treat in the parts. This is especially important for lifting items. Cold bluing may be ok. I was wondering if even the acid to clean them was ok due to hydrogen embrittlement. A better process would be to boil the rusty parts to change the red rust II iron oxide to III Fe3O4 black iron oxide (rust bluing). You still get blued parts while avoiding any chemical changes to the steel and also save time cleaning the rust off only to recoat it. Win-win
Yeah, nice job, I wish I had one of those, but......... it's rigged wrongly. The lifting hook isn't just a fancy lifting hook, it is part of the lifting system. The loop round the pulley should be cut and fixed to the main block, possibly to one end of that guide bar you painted red? Then it will add a 2:1 mechanical advantage to whatever the nominal mechanical advantage of the gearbox is. As I say; nice job, but it ain't fixed yet!
20:56 - couldn't you clip the disassembly process and reverse it in your editor? That way you have a reassembly instruction vid to follow along with (secretly, behind camera of course 😉).

Boy you deserve the 👍 for figuring out how to put it back together ……legend…..good luck from 🇬🇧 U.K…Peter P
It was reaaaaly tricky though! hahahaha
I am so happy to see you restore a useful tool after it has been discarded...I enjoy watching an expert at work. Looks like you are feeling better
Wow, thanks!
Excellent friend another saved item, have a nice day !!!.
Thank you! Cheers!
Nice to see it working again

My dad has a bunch of these in the garage. Don't know why he had so many.
I agree.
Good job. I still love the birds in the background.

Glad you enjoyed it! I try to keep the items as original as possible. Also there was nothing wrong with the chain other than some rust.
Yeah...
Except this isn't meccano...and what he's got there isn't safe to use as it is...🇬🇧🙂

Excellent guy. Thanks for the video my friend.
Can’t believe how many parts there were that made up that device. So complicated!! Well done.
Yo, these videos are off the chain!! 😜
Hahahaha lovit!

The acid was awesome, I am so glad I decided to do a little timelapse on it.
@@AJRestoration Phosphoric? Hydrochloric? Citric? Great job on chain.
And now I am going to do mine this winter.
Good luck!
Superb works
Very good rebuild of a good, high quality tool. It now has decades more of useful life. Thank you for saving it from the scrap yard.
Thank you very much!
love the paint job, nice contrast
Thank you, I also liked it. Especially the red and mint green.
I have yet to see you do a bad restoration! Great job!
Haha thank you!
I already know the final result is going to be amazing and everytime im still shocked at how good it came out!
Another beautiful restoration!
Terrific job mate. Thanks for the video.
Glad you enjoyed it Iain!
love your work! I always degrease first before acid wash as the acid just cannot work as well in the presence of grease -
Well done! 😃👌🏼
excellent professional a big hug 🇧🇷
Superb Joe, great vid

Good morning from Southeast South Dakota
Morning!
Just watched your Governor from South Dakota on TV. I have to say, I'm jealous! If your state was a little further south, I would love to live there!

Excelente restauracion realizada a esta grua de cadena, respetos desde Venezuela💯🤜🔥🤛👍🙏💯💯💯
Great restoration - happy to bear with you but decline to bare with you. 😹
😁
I would like the acid., but impressive stuff! Well done.
very good job sir
Top job mate, came up real nice!
Tout simplement superbe très beau travail de restauration magnifique
Very good Job Love it ❤️👍❤️
I'm glad you like it
I like the period pop rivets.
Those were new old stock, from 1594.
I have used many of those over my long years of putting in Passenger Elevators. Non of them looked like that. Nice job.
Absolutely Amazing job 👍
Thank you so much 😀
lekker man, nice video
Baie dankie!!
Very cool well done.
Nicely Done!

You are absolutely right
i was to say the same.. you ers right
And it increases the mechanical advantage if I am not mistaken.
@@BigMouth380cal kinda, yes.
Yes, you are correct. I have this same chain pully hoist.

Thanks so much Rochelle😊
Nice job.
Thank you! Cheers!
Awesome!!
Thanks!
That was a amazing restoration, good job.
That chain hoist saw better days but you got it back in running condition now you have a chain hoist for your help with other projects to do
That is one of the reasons I got this, I needed one and this was the perfect candidate.
@@AJRestoration great. That is the one that you needed

Te felicito. No sé realmente cómo haces para recordar dónde iba cada pieza y su función. Puedo desarmarlo pero no armarlo . Maestro!!!
So instead of taking photos or indeed watching your own video of the disassembly, you bascially guessed how it went back together!
Its not always that simple.

If you do decide to fix the chain, would you please make a video of it so that anyone who wants to refurbish one of their own, would be able to refer to your fix as a guideline?
Not one chain link was measured and determined if they were over stretched or not...failed rigging class 101, but you absolutely aced everything else.
Haha I get what you are saying, for my purpose its perfect. It never going to lift more than 500KG if lift anything at all.
12:29 Dude... I did some really good acid, when I was a kid (almost 40 years ago now) (haha).
Hahahaha First one to get the joke.
@@AJRestoration excellent restoration on the chain roller.
Looks great!! Looks like it might have been a pain to take apart and put back together. How many times did you have to look at the video to put it together again?? LOL They last forever!!

Haha thank you, I had it apart probably more than 10 times.
@@AJRestoration Haha You are very welcome!!
Great restoration mate looks sweet. But I do got to ask why u didn't put more bog on that front cover and smooth it right for a better finish?
I didn't want to remove all the dents, I liked the rough finish.
@@AJRestoration I understand mate thanks for the answer. See u on the next one.
only question is i didnt see a reverse set up on this how do you let stuff down ?
What did you add to the water for the chain soak?
Perfeito Parabéns !
'Please bare', as opposed to 'please bear' is the difference between getting naked with someone or asking for one's patience.

Don't powder coat the hooks, that paint cracks and flakes off. Bluing is a better choice.

Бро, эту таль и особенно цепь надо испытать. Очень рискованно без тестов использовать…

Does the chain only go one way? How do you let stuff down?
It has a reverse pin/lever on top.
Подписка!
wow what is this paint powder to cook in the oven ?
Очень оригинально использован блок.
you should have painted the raised lettering a contrasting color
👏🏻👏🏻🇹🇷
How did you clean up the Chains?
Dipped in acid, dried then dipped in used car oil and left to drip in a drip tray for 4 days. Wiped off the extra oil and that's all.
@@AJRestoration Thanks
which color is that? RAL...?
20:56 - couldn't you clip the disassembly process and reverse it in your editor? That way you have a reassembly instruction vid to follow along with (secretly, behind camera of course 😉).

You greased the friction plates! Big no no.
This is not a restoration, it's just a cleaning and painting
