That is an incredibly tall specification order you are trying to fill
there. You want 150 lb. components that one person can put together in

Or a block and tackle type device that attaches to the box top.

Once again, how that will break down into 150 lb parts is unknown.

The biggest hoist I've built weighs about 150# total, 4x 35#, and
lifts 6k#. And it takes an hour to set up.
