my old new engine crane
new motor cranes seems all come from China, so I decided to overhaul my old motor crane and upgrade it with a winch with radio remote control. For the idea with the winch I want to say thanks to Jack! Because of this, many jobs can be done alone, which normally would require two people to do. The jack is a very high quality device from the end of the 60's when there was still a "made in Germany". The oil pump and the hydraulic valve are "made from the full", no bought-in parts. All seals and hoses etc. were renewed, all sealing surfaces were reworked.
It now lasts 50 years again.
Here the test run:

That's quite a beautiful piece of equipment----nice transformation. I've rarely seen such a robust or well built lift in all but the heaviest big truck shops, can't remember a time seeing one even similar to this one.
Its nice to modernize a long-lived shop tool making it more to your use---nice job!

That is a great piece of equipment!!!!!!!!!!!!!!! In 50 years when we are all dead.... somebody will look at that and say, "Wow, somebody built that themselves and really knew what they were doing"...... when in fact, they will find it in the history books of when things were built to perform, not just built to meet the minimum specs the cheapest way they can......The mods are great too!!!!!!!!!!!!!!!!!!!

Nice/great job. Thanks for sharing.
I think California is mandating that in a couple of years (2035) all new cars will be electric.
or zero emissions.

I hadn't seen this thread since I hang in the 6.0 forum, that a great restoration Hartwig, and thanks for the comment. That crane is worthy of commercial truck and equipment repair.
For us folks that are dealing with what we can buy today economically, here is the conversion of an electric winch onto a HF 2 ton that Hartwig was refering to. it has worked very well for a number of lifting projects, not just a Powerstroke.

With mine, so far I've used the winch to pull up 2,000lbs and it's held. Not what it's made for ...... If it was a worm gear drive I wouln't have put up all those warnings in the video. Agreed, not without the possibility of moving.

For the sake of a few dollars I'd opt for the right tool for the job especially when dealing with heavy objects.
Just my $0.02 worth mind you!

That's why there are warnings to do that at the beginning and end of the video.
In my gantry crane training, with the proper hoist, the rule always is don't be under whatever you are lifting because rated hoists, cables, chains, slings, lifting eyes, or hooks can fail. And why I had our gantry crane inspected and tested every year by an outside source. There is no time removing or installing the engine that you do not have a substantial block (cross member) above you. The hoist, made by HF or whomever as designed, can also fail. The adjusted load with the reduction pulley is 18% of rated capacity.

For light things like heavy crankshafts etc. no rope brake is needed. For heavy engines, however, the hydraulic have to be used, I don't want to do that by the winch / cable brake.
But the problem is, such a simple hydraulic system (also freshly overhauled) can drain a few mm (0,xx inch) after days. If I now have an engine with the clutch/converter in the gearbox and the unit slowly lets off unnoticed, it would be catastrophic. Often I notice that I have to order parts in the US that take 2-3 weeks to arrive here in GER. That's why the hydraulics are now infinitely variable. The stabilization, ( I used an old hydraulic cylinder ), can now be fixed with a hollow drilled stand, accurate to a tenth of a mm.
