By adding a few things to the fork carriage of my backhoe I have pretty much transformed it into a skyhook. Well Hardly but a very useful addition to my arsenal to say the least
First off I had to repair an old roofing hoist I had in order for any of this to be worth doing.
I made a mount for the hoist and a gin pole this will allow me to use any length pole that I can safely pick up with the loader
Then I made a pair of chain eyes to use as anchor points for when I am carrying long bulky and otherwise unyieldingly hard to carry loads on the forks, also to use as stabilizing anchors for a Mono gin pole.
Next I made the top block point sheave to fit on the pole and to anchor the ends of the chains with to give me triangular stabilizers for the gin pole.
I left a lip on one side then staked the bearing in the sheave.
Put it all together with the pipe I used as my spreader bar extension
And this is what I came up with
Now I will be able to fly the purlins a few at a time then afterwards lift the insulation and the sheet metal

So the roofing hoist is electric, how do you operate the tractor with that attachment? Extension cord seems to be a pain to keep from being ran over and such. I'm surprised you didn't put a hydraulic motor in the hoist and add a spool valve to your control.
Looks like you fabricated the big cable sheave, from scrap, and got some lathe work as well.
I have a 10,000 lb 12v Ramsey I could have used and may install it someday I also have a 13,000 lb Tulsa hydraulic and a spool valve that could be added to give me auxiliary hydraulic power either winch would be a better alternative to having to deal with a cord but both would have required a lot more fabrication and connection time and possibly money to mount and connect Also I didn't have cable for either one and both would have been over powered for what I need to accomplish at this time. Plus could lead to my trying to lift too much weight overpowering the balance of the backhoe or compromising the gin pole. This is not to say that either might not be modified to mount at a later date with a shortened gin pile though.
The roofing hoist is awfully fast so I might add a sheave and 2 line the thing to cut the speed down also giving me more lifting capacity or I might add an SCR controller to slow it down if need be

The last time I saw one in action (RF remote control), the roofing supplier was delivering (flying) to my garage roof top shingles. That was reaching over a lower roof garage space.
I take it that the motor must be a universal motor. That's a good thing.
Hope to see the unit in action.
Brings back memories from about 20 years ago. I had an old Allis Chalmers Hdg6 track loader probably from mid fifites. Had a 2 1/2" thick wall tube welded on the back of the bucket. We had been on 2 week vacation and on return home had no water. We wete on 10 acres in the country. The well was 160 feet deep with submersible pump. I stuck a 20 foot length of 2" pipe in the square tube and hung a pulley with a rope from a chain hooked in the end and raised as high as it would go. I made an adapter to screw in the pitless adapter and pulled the pump with the whole lengjt of pvc pipe still in place. The new pump was about $300. The emergency service call and pump mark up to replace it that I did not have to make would have been about $1700.

To make my gin pole & hoist more user friendly IE to slow down the rate to lift or lowering I added the 2 snatch blocks I made this gives a 3 to 1 reduction in speed and also increases the load capacity of the hoist not that I needed that
now the gin pole takes on the resemblance more similar to that of a small crane
First the 4 inch block was added to the top
Next the cable was reeved through the 2 blocks and hooked to the top of the 6 inch block giving me the 3 to 1 reduction in speed.
It is worth noting that the hook on the cable is rated for 1 1/2 ton the hook on the block is rated for 5 tons which keeps the proportional strength in play not something that was planned it just happened that I had a 5 ton hook laying around and it looked like it would be the perfect place to use it
