Good place for a model railroad ![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

hey it’s winter time even in balmy B.C.
I never thought of a hoist, bet that could lift close to 800 lbs... hmm... be like... toys in the attic!
I recommend a home-theater set-up.One poster suggested a model railroad up there and yup,that would be a great idea - if I were a model
hey I was gonna say I like the '20s look of that hand rail, real water front look with the sched 40 pipe and fittings [especially those floor flanges! everything's pro press with these young guys now] I would have preferred a little yellow teflon but looks great.
With a three wrap block and tackle I think your winch will easily lift any ST or Harley up there pretty easy, but, in all seriousness; the weakest link in the chain is your building structure; posts, beams, rafter spans and rafter design [yours are way better than mine, my verticals are planks!] I've seen the full force of what goes up come down and another one go sideways with a pneumatic [should be illegal as far as I am concerned[ Genie lift, almost eliminate a [big] human being.
In the absence of an engineer's approval, over build your anchorage, find something that works, copy it and double it, what's the rating on that single pulley 1/4 av cable, I'll bet already over 1000 lbs with only only one spin, enough to bring the roof down.
MaxPete,
I seem to remember that you were an engineer by trade, but it might be a good idea to track down the load rating of the roof trusses before you notice a sagging area in the garage ceiling because you overloaded the trusses.
Neal (also a retired engineer)
edit to add that I mean the load on the deck, not the hoist load. As in pound per square foot (kg per sq meter)
He wrote that he won't be hoisting anything even approaching a weight of 100 Lbs. using that crane. I don't think that he has anything to be concerned. Lifting such a small amount of weight as that won't even stress the roof as much as the load from a a decent snowfall will.
In the picture that was posted, the roof support is very closely concentrated in that area. There are four vertical trusses that all meet the horizontal truss at the peak. That is a lot of support concentrated over a short distance. This arrangement repeats over the length of the roof at what looks to be a distance of no more than every 24" as well. I wouldn't even be concerned about lifting 1,000 Lbs. if the hoist was capable of it.
My garage roof has no where near that tight a concentration of support, and at a much flatter angle. I hoist snow-blowers, motorcycles, generators, all kinds of crap up there with no concern at all and with no roof sag.
I don't think that he needs to worry about it.
