Great idea thank you. I should mention one thing, please be careful using this piece of equipment, it is not an engineered lifting device. If something should happen you can be in deep waters. There are lots of steps to designing and fabricating lifting devices, I know I design and engineer them for a living.

Do not go under flying steal plates!

As much as I like to build my own tooling and fixtures I must admit you are correct. Although the device may work 999 times out of a thousand there could be that one time it fails and someone gets hurt and guess who gets hauled into court and sued. I have been asked many times by customers to design and build things and I always look at the safety and liability end of things. If the person can go buy something that is already proven and works I advise them to go get it or I can make the deal and get it in for them. For personal use hey its great I used to farm for a living so I know you have to make due when you can. So please don't misunderstand the message here is not to attack your idea it's more to inform you from my experiences having been in the welding field for 30 plus years. ... GC

I did not mean any disrespect on the design, just stating the if someone should get hurt by something without a engineered design and stamped drawing for lifting mechanisms you can get into great amount of trouble for it.

For your question Peter, I will PM you.

Peter - You did answer my question! Thank you again - -

Thanks for posting.

Thank you for posting. I have not built the ones I drew up a while back. Might use yours since I know they work..lol..For the last year I have been doing it the oldtimers way with 2 pieces of angle welded together on top of each other. I have one set with a 3/8" gap for small sheets and another set with 3/4" gap for 1/2" plate or stacks of 14 g. But figured I would share a chain key here to go with these. The one on my 3/8" plate carrier is 3/16" plate and have actually picked up 1000 lbs with it. I dont trust it so I cut one from 3/8" that I leave on my large set of clamps just for safety. The hole is a perfect size so I can actually pull it through overlaping to angle the metal for my cart. then when I hook the hook back in there is not enough space for the chain to slip out.

I had a discussion on a forum here in Australia about this matter. It was shocking how the liability for a manufactured part can be put onto the machine/job shop that made it for a customer.

It would be 100 times worse if the job shop designed the part and manufactured it. I would love to know under what conditions does the job shop have liability. For example if a customer just gives a drawing of something and the job shop has no idea what it is, is the job shop liable is that part ends up used as part of a weapon, or a lifting device that fails, etc. Do job shops have a (forced) responsibility to ask, "And what will this part be used for ??, etc, etc."

No offense but this should be redesigned for safety. Just noticed you have the cable pulling the tension arm the wrong way. This direction could kick the metal out. You want it to pinch the opposite way so the weight of the metal is used to pinch its self and lock it in.Here is a picture of the proper direction i did real fast in paint.

Hope I didnt step on toes just dont want to see anyone here get hurt doing what they love doing.

Always over engineer to start. And some items you can offer at a lower price as a kit so the customer can weld it up. Some market this to save money on shipping when truly it helps free alot of liability. Other than that yes it is very easy to have it come back on you. It is sad how most people will not take responsibility that sometimes accidents just happen. I call it population control.

here is the chain holder

I'm sure your aware, and I myself am guilt of it, but that is not lifting approved chain. Again, just an FYI incase of the whole liability thing...

Howdy

Guess it is something to do with driving on the opposite sides of the road..hahah..

HDJ is correct. here is the type that I use. as you can see, the pinch foot should work so that it is tightened when pulled to the center of the sheet where the chain is hooked for lifting. This unit is made by Nuline and is rated for 3/4 ton. you can see the positive grabbing teeth which helps to keep the sheet from slipping, but it is still a bit scary when the thinner sheets belly out and you're standing there wondering if it will hold on till you get it loaded on the table...as my Dad would say "makes your butt so tight you almost pop a hemorrhoid".
Anyway, safety is always first, so just use your head and don't load more than you should on something that is not tested and rated for the weight.

Pretty sure the Germans drive on the same side of the road as we do.
