One can use a ladder so long as there are provisions for hoisting 
equipment up and down.  Basically there must be a structural frame 
above the access hatch from which to hang a block and tackle or the 
modern equivalent.

I installed such a setup in my attic, so I could store 100# air 
conditioners in the attic over the winter.  No way was anybody going 
to harry that thing up and down those rickety folding starts.  This 
hoist has been very useful over the years.
