I use a hydraulic lift truck for this purpose, but it was quite expensive:

I justified the price to myself when reassembling my newly-acquired Nova 3 with the
observation that it's cheaper than back surgery.
The truck is itself heavy enough that I need to be careful not to hurt my back when
man-handling it over steps and so forth!
