I’m all for making stuff. But in this case would a second hand engine crane not just be much easier and quicker?

My 1 ton folding engine crane has a jjb made of box section about 70 mm square, so that should be quite suitable for lifting 125 Kg, although as the extension increases, the safe maximum load decreases from 1 ton to 250 KG at maximum extension.

For inspiration, visit your local Machine Mart depot nand note the dimensions of the jib and the supporting structure.

Not only does the crane need to support the load safely inn the vertical plane, but also to be stable laterally.

No point in lifting the machine, if the crane is going to damage it when it topples over sideways!

How about a scaffold crane- £100 from screwfix.

I needed a crane to pick my indexer on its mounting plate which weighs around 90Kgs. The indexer along with rotary tables are on a trolley. The crane is used to pick them off the trolley and lower them onto the mill table (table being moved to extreme left hand position. I had an Aldi/Lidl hoist and bought a jib from Ebay. I needed longer jib than that supplied so swapped out the inner section for a longer one. I would have liked it longer but decided this was not a good idea. One of the guys on this site did some calculations to confirm it would handle the load.

The steel scaffold pole is located in a metal plate on the floor and the upper location is provided by a steel plate bolted to 41x21mm thick wall Unistrut. The each length Unistrut is bolted to at least three roofing joists and is also clamped to and supported by the overhead RSJ girder.

It had a little more flex that I liked so a large steel clamp was machined up and bolted to the wall with long rawlbolts.

It may not look over pretty but certainly works.

If you want a 2 metre reach I think you will have to significantly increase size of support pole and beam.

Jib implies it moves in an arc. 125kg at 2m or rather the test load, of either 1.3x or 1.5x for a hand hoist (if I remember) adds up to a lot of moment, so you may have to dig a foundation of a tonne or two to stop it tipping or ripping your house apart. Jibs are very expensive all in.

Far, far easier is a travelling beam, or fixed-each-end beam, it can be far lighter and easier to move, probably aluminium if you buy one with A-frame and castors.

Another option is a track screwed into the ceiling beams. As you know what its for you can probably think of a few routes that it could follow.

Good luck.

I bought one of these for loading my pickup truck:

I made a pedestal that mounts to my shop floor. The crane portion drops into the pedestal. I also made a boom extension that telescopes inside the main boom. Of course it is necessary to de-rate the capacity when using the boom extension. I hung a small electric hoist from the end of the boom. I use it mainly for changing chucks on my 16" lathe.
