How can I safely store my aluminum truck cap inside my shop from the cieling? ?

I wish to hang my service truck cap (200 lbs) from the cieling of my shop.I have 12' of clearance.Has anyone done this before?

I've a friend in Brisbane who did something like that. Easy storage with a hook kind of thing and a shelf. I'm not quite sure how to describe it but let's just see if I can get the details for you…

I found a top cap ez lift at a yard sale and I really like it.

My cousins job has these truck cap hangers. All it is is 3 small aluminum beams (they look like shiny 2 x 4 's) hung up by those threaded bars (you know, the things that look like 6 foot long screws). It is like a shelf. Just be careful attaching the rods to the beams, use 2 or 3 nuts to hold it. Message me for detailed plans/description.

Lots of people have done this before. Do a Google search for "garage ceiling storage" and "bicycle hoist." Obviously, you're going to find commercial products, but their design should give you the guidance you need to do it yourself (or help you decide to buy something already engineered). The basic thing you want is a single-threaded, four-point block and tackle system (the bike hoist is a two-point block and tackle). That way, you just have one single rope to pull on; the pulleys will ensure that balanced force is applied to all four corners of your truck cap, and will multiply the force so that you're only exerting 25 lbs of pull (200/4, plus another factor of two for each b&t). If you anchor the four ceiling pulleys individually with a lag bolt, each one will only carry 50 lbs of load, far below what a joist and bolt can handle.

I would attach 4 pulleys to rafters (you could run a 2X timber perpendicular to rafters if concerned about over-loading- but 200# shouldn't be a problem unless the roof is collapsing already- in which case you have bigger problems to deal with than storage) attach 4 ropes together, attach a rope to these, run this rope thru a couple of pulleys (to direct the rope where you need to pull from). At this point you need to hoist the load- you could use a winch (a boat trailer winch might work?) or your truck? If concerned about security when cap is up you could use short ropes or chains to keep it in place. Hope this makes sense!

There are 2 parts to this. First is how do you hang the cap so the weight is distributed over the ceiling joists so as to not drag down the ceiling. Secondly how to actually hang the thing. You could add joists to carry the load parallel to the existing ceiling, or run a pair perpendicular to spread the load out over a couple of joists. Should be the same for trusses or joists, at least my 20 years of construction have me make that guess. You will need to get the load spread out far enough, the exact determination of is in the province of a licensed engineer, not a carpenter. That said, if you run beams on top of your joists & have them extend for 2 or 3 joists past the hanging points I think you'll be fine. As far as getting the cap in the air, you may need to build a cradle for it, supported by a strong enough line. Chain would work well. All in all, a load is a load, whether sitting tucked up in the rafters or hanging from them. If you do have trusses I would avoid attaching directly to them, run a beam parallel or perpendicular, but avoid adding a lot of load to 1 or 2 trusses.

Most truss roofs have enough extra load-bearing support to deal with 200 pound. If not, theres a problem (think of the weight of the roofers working up there, or snow-load). Make sure your supports are attached directly to the roof trusses.
