I have never heard of anybody building a large hangar without pre-planning. Usually drawings of footings/foundations, grade plan and structure are required for municipal permits. I'd much rather Install a footing or piles for the vertical load of the two hydraulic cylinders than pay for the structure required to hold up the door over a 50 or 60 foot clear span.
It's not the answer if you are building a wood pole structure at a rural strip with no utilities. But the OP said he was building a 60 ft X 60 ft structure (which I assumed is all steel) and you wouldn't catch me investing that kind of money without power (and where I live water & gas) to the site.
There is nothing magical about hydraulic cylinders. You can stop the door opening and suspend it at any point in its travel. My neighbour and friend who has one of these regularly cracks it open a few inches to a few feet to ventilate it, or let in the sunlight when he's working on the RV-8 he's building (His other airplane is a Tiger Moth he restored). In a high wind any sort of door that protrudes from the building is a risk when open.
I have a 20 ft high bi-fold on the 55X65 hangar my plane is in. The overhead truss to suspend this door is pretty impressive, and required some serious foundation pads for the columns that hold it up. I'd trade that cable operated door for this type.
