A 10' ceiling can work with a hoist though it's a bit minimal. I had 10' at my old shop in Ann Arbor with scissor trusses over the hoist bay - worked OK though you did need to use some caution and a pick-up could only go up just SO high. So this is my second shop with a hoist (so I've had one for about 20 years or so) and at my age I simply couldn't (and wouldn't) do what I do without it. I encourage you to look into it. Best thing since sliced bread.
