I would be a little concerned about using that lift with the floor jack. I am not an engineer, but we have several on this board that may agree. It appears that there is alot of stress on that little jack. They are designed to lift relatively straight up, and rated accordingly. Lifting something, of considerable weight, that far from the lifting point on the jack, would require considerable strength. Consider that, by the time that you lift the tubing and chain from that end and angle, you have used a large part of the capacity of the jack, what is going to lift the engine? Ever try picking up a piece of square tubing from the end and holding it straight out? That is what that engine lift is trying to do. Then also pucking up an engine. It would have to be a 30 ton jack for me to feel comfortable with it.
The engine stand that is at the German site looks like it will hold up most any engine it needs to. I built one many years ago, using 2 1/2" angle iron, that I welded together to make tubing. I don't have the braces on it, like he does. Mine has had a complete 390 Ford engine on it and didn't budge a bit. If I was going to do alot with long straight 6's I would probably add bracing.
I bought a book from The Eastwood Company 12 years ago called "The Racer's Guide To Fabricating Shop Equipment" I made an engine stand from it and I'm proud to say that after 10 years its still going strong
If you are a Sam's Club member or know someone who is, see if your local Sam's has or will get you a 122442. This is a Goodyear Racing engine hoist. It comes with an engine leveler, has low profile leg design (wheels are up in the legs so it will roll under low cars - if you ever used one with casters under the legs, you will understand), folds up, and is a very nice piece. I bought mine for $169.99 plus tax in Tulsa. From the Sam's web site, it may have gone up $7. Unless you are getting the steel for free, I don't think you can build one this cheap, even if it is not as nice. Go to the Sam's web site and search for 122442.
OOPS. I just noticed that most of you are in Europe. Don't think there are Sam's Clubs there. Oh well, those in the States reading this thread should check out the Sam's unit.
This won't work for Europe but these are good items to buy from Harbor Freight. Watch the sales and you can get them cheap and ready to go, likely for less than you'd pay for the steel alone. I have an engine stand, an engine hoist, and a 20 ton H-frame press. They work great for me and I've got less than $400 invested in all 3. I like to save my effort for other things when I can find that type of equipment cheaply.
At those prices you mention for the equipment it's obvious that material cost for a homebrew project will probably be higher.
Only is it impossible to find such equipment in Switzerland at those prices, here all you usually get is the professional equipment at professional prices. So you'd pay more for the crane alone than you paid for all your equipment. And finding used equipment is like looking for a needle in a haystack. The fact is that there are just not enough car enthusiasts who do everything themselves and need such equipment over here.
53 ford guy .. I see you are from Canada. Princess auto sells pretty good ones thar fold up out of the way when not in use and they are pretty cheap ... $159 or $169 sometimes cheaper on sale. I've had one for 4 or 5 years and still works well
