I have loaded and unloaded almost all the pins I have went and picked up by myself. I only weigh about 165 lbs.
I remove the head, stand the cabinet on it's end, remove the legs. truck it to my truck on a dolly and lean the cabinet on the tail gate and push it in....pretty simple.
...I also have three steps to get it up on my porch to get it in (about like the steps in this thread), but never needed to build anything like that to get in up there....and I am talking about doing it by myself.

I bought a machine once that didn't work when I went to look at to purchase. ended up paying $100 for it because it didn't work. I took the head off to transport. got it home and put the head back on, plugged all the jones connectors back in, turned it on and had a fully functioning machine....found out that many problems on em's are bad connections and that's it.
....found same problems on ss's also.
