Lift horizontally out of the vehicle onto the ground and two people should be able to get it vertical though I would not do that until it is close to where it will live. Lift from the horizontal with the crane and a combination of crane and people power to get it from there to vertical. There is no need to complicate it but they can be tippy if allowed to get away from you. I did my 18" on my own from trailer to upright using a chain block. The other way is tilt the whole trailer to slide it out and stand up the BS from there. This requires more people as the trailer will have to be lowered.
