Guess what my engine crane started as Ray? I replaced the electric screw jack with a 3ton hudraulic ram. The weak point ended up being the castors - they finally gave up when I lifted and shifted my Douglas with it... that weighed 375kg roughly.
I also have a hydraulic stabiliser leg for my trailer when I use the top half of my 'engine crane' mounted on the trailer. It started life as a bath lifter for patients - just straight up and down lifting of a plastic chair on a swivel, bolted to the ground next to the bath in the hospital.Cheers,
Joe

My friend Joe the toolmaker(refer last weekends grinding caper elsewhere) has a mechanical steel cable winch version of such a mini forklift - only about 600mm reach. He uses it to pick up, position and move the dies he makes. We moved all my mill parts from my car to the grinding room with it at once. I'd guess about 200kg. VERY easily. Some of his die blocks would weig 500kg before machining (like the lump of round steel bar I showed in his lathe).
That would be a good project to design for Ken 'neksmerj' to come up with for DIY manufacture. What do you reckon Ken? I'll try and get a photo of the one Joe has as a starting point.
Actually, it was exactly like this one: http://www.genieindustries.com.au/si.../GenieLift.pdf linkted by eskimo, only heavier construction...Cheers,

I have a second hand skyhook. Winding it up and down is easy and when I one day get to fitting it permanently I will be using it for loading things on machines, most particularly the dividing head which I think is around 40 to 50kg. For me the important feature of these things is that it should stop me bending to lift heavy things in a confined area.
The biggest problem with it is access to the handwheel. You really need to be standing behind it or on the left side and at the moment I can't work out how to position it so I'm not reaching over it or out of position when using it. Mounting on a trolly is one way around it but that takes a trolley from a low profile thing that can roll under a bench to something that has to have it's own parking spot.

IMO, yes. I have one of those generic cheap truck cranes fitted to my 4WD flat tray. 500kg lift in theory. It's far more useful with a Beaver 500kg lever block hanging off the end as you have fine positioning and very controlled lift/lower ability. I use the hydraulics for coarse positioning and the lever block for the fine work.
I'm going to build some post cranes attached to the wall, first one will be for the Monarch CY lathe. Lifting and fitting a 12" 4 jaw chuck manually is just asking for trouble, it's heavy, awkward and you need to lean over to get it to slide on to the spindle. And yes, I know all about chuck rests/boards etc, doesn't solve the lifting and positioning on the ways part of the job.
A skyhook attached to a mobile trolley looks like an accident waiting to happen unless there's a lot of counterbalancing mass somewhere.

Stuart . Look at H & F pn 358A. Recon 1 could b made easy enough to lift a chuck. Design looks straight forward.

I will never be the person who has everything, not when someone keeps inventing so much cool new stuff to buy.
From an early age my father taught me to wear welding gloves . "Its not to protect your hands son, its to put out the fire when u set yourself alight".

Just came across an old photo I took (that's me standing on it actually)....
Could be adapted and construction is pretty simple.

Ray this is something i knocked up when i was between sheds, my gear was spread between 3 sheds at the time and i couldn't move anything to my new shed as i needed the space for the timber for the house i was to build. As you know i have one mechanical knee, maybe you didn't know the flesh one is buggered also. I had got it in my head that i wanted to build a solid timber home, i got my plans passed and i had recently then put a hydraulic/cable feed on the father in laws portable sawmill, so we got some forestry pine logs and sliced them into 4 x 2's, while waiting for the timber to be dried and put through a 4 sider i built this thing.
There was no house frame, the construction of the house walls was by fixing each piece timber on edge on top of each other, 9ft high, glued and fixed with 6" bugle head batten screws, scaffold would of presented problems by constantly getting up and down from it.
I built this thing out of off cuts and bits and pieces, it was built with a 9" grinder, a 4" grinder, a bosch drill, 2 shifters, a small arc welder and a 50 mtr extension lead from the builders pole.
The base, differential/axle and wheels were from an old slasher, the uprights are tapered flange beam from an industrial embroidery machine, girder trolley (half each side), 12v electric boat winch and a 24v electric wheelchair motor.
It is approx 750w x 1100 long, it has a travel of about 450 to 1500mm high.
With a few mods it would likely do what you want and it's yours if you want it, if not it might give you some ideas.
