Been reflecting on my earlier suggestion of something mounted on a work cart.
Scaffold pole pivot at one back corner carrying a two section bent jib, wheelchair hoist style is current favourite. Short strap or chain between the jib and object to be lifted so no winch needed. Either use a ratchet strap so its adjustable or have a couple or three ones of different lengths.
Actual lift range is inherently limited but making the angle between the jib sections adjustable with a choice of two or three holes for a pin should give enough height flexibility to cope with from floor up to higher than the machine. Albeit in one or two bites with an intermediate table midway to set things on for re-adjustment.
Looks as if it can be made to fold neatly behind the cart. If working over the cart should be stable enough not to need axuillary support but a brace of fold out legs would be desirable so you can work out of the corner. Maybe screw a paving slab or two under the cart for extra stability. Probably not needful with mine as the drawers are full of spanners et al and the sheves always have heavy "crap" on them.
