Sorry to hear.. been there myself.. not pretty.. manhandling a Techsew 180 (its equivalent in my part of the world)..took 2 of us to move it into the vehicle.. but being alone at the delivery end - ended up backing up the vehicle under a house deck and stropping to the railing and pendulum'ed the head to a mobile table.
I use a motorcycle scissor jack to move stuff around.. but it only lowers to ~350mm to the ground - so lever stuff on blocks to that height and shuffle the gear on. On the shopping list is of course an engine lifter to avoid these shenanigans. fyi ..I'm alone.
There are other solutions - has been discussed at length here before...but a trade off with size (getting stuff though house doorways) and price .. things like pallet jacks with vertical lift arrangements like a forkhoist - again price considerations.
