You can modify some trusses to get a full height lift in there.
This is what I did for my hoist area.
Looking toward the garage door you can see I plated the entire truss on either side of the bay I was opening up with OSB.
Added collar ties to the three rafters I was cutting out. After the middle of the truss was removed I plated the entire top of the opening with OSB. You can also see the verticles I added to the two end trusses to give the added OSB something to attach to and give it some robustness.
I also added 16" engineered floor joists at both ends of the opening.
These go thru three sets of trusses on both sides of the new opening.
In this pic you can see where the three trusses were cut of at the engineered floor joist.
The cut off trusses were tied into the new structure with joist hangers on the back side.
If you do something along these lines you should be okay.
