I loaded my very similar one into a transit van with 2 guys helping to lift it in.
To get it out, I laid it on its side, fitted the 4-big castors while it was in the van (that I was fitting anyway to make it easier to move about) - & two of us eased it off the back of the tranny & sort of tilted it upright.
It worked fine, but yep they are hefty & it wasn't an HSE approved method .
Tbh while I checked mine over by looking inside the tank, & I changed the pump oil - I didn't touch the pump heads etc - I just ran it up to full pressure
