Has anyone put up a over head electric hoist in their pole barn. I'm in the process of finishing off my interior walls and before I do the ceiling I have been trying to get several suggestions from people who has done this. My barn is 24x40, trusts are on 4' centers except 2 are at 2' centers, that I'm planning on using to mount my hoist in between. My plan right now is do span 4 trusts. Total lift capacity of my hoist is 880 lbs. Anyone have any thoughts, pros or cons.

^^What Brian said. I would verify the trusses can handle that. 800 lbs is a lot of weight to put on the lower truss cross-piece if it wasn't designed to hold it. My polebarn is 22x32, with the trusses spanning the 22' length. I put in some shelves that are 2' deep along half of one 32' wall. I have the back of the shelves tied to the walls of the polebarn, and the fronts are supported by 2x6 boards that are connected to the truss lower cross-piece as well as the truss top rafter. On the bottom shelf I also have an angled brace going from the front of the shelf back to the polebarn walls. Even with all that I would be hesitant to put 800 lbs on the shelves. I probably have about 600 lbs on them.

EDIT: My trusses are on 32" centers, which is a good bit less than 48".

I'd be afraid to add 800 lbs. to those trusses unless they were installed with the load bearing in mind when you built the barn. I'd look at an independent stand anchored to the floor.

Unless the roof system was specifically designed for it I would not do it either. I always figured the roof system is not something to be guessing about.

Most roof trusses are not designed to take on extra vertical load (above and beyond insulation and drywall) on the horizontal beam or ceiling joist. Some trusses are designed for an extra room in the attic. Those will handle the extra load when distributed correctly. I would check with someone who sells trusses and give them a description of what you have. I suspect from your OP that you do not have what is needed to support your hoist without some modifications if at all. I have seen doubled up ceiling joists sistered with the trusses to beef them up. This could be an option, but consult with an engineer before going down that road. The load must be distributed equally to be successful. You don't want the headache that would come with a failure.:banghead:

Ya I agree. The two trusts that are on 2' centers have a 8'' bottom joist, I told the pole barn company on what my intentions were and their engineer said with those two trust at 2' centers it would carry 1,000 lbs counting my hoist and with what I use to mount it with all figured in the total weight. I'm very skeptical about it. I had planned on doubling both of the 8'' trusts then tie them into the top rafter. They suggested spanning 4 trusts, but I think just those 8'' would bare most of the weight with the other 2 carrying little or no weight. Now if I was to put a beam up as to use a trolly that would be different. I'm just throwing this out there to get different suggestions, whether how to do it or not.

Make sure to keep the engineers blessing in writing somehow.

If you have the barn plans, I will happily run them by a structural engineer for you. He will give me a yes, maybe or no for you.
Thanks for the offer, the designer engineer from the pole barn company sent a drawing for what I need to do for the extra support. The trusts were already designed to carry the extra weight for a osb ceiling so there not alot more other than sistering one joint on each trust. Before I close the ceiling up I get a picture of it with my hoist installed, it will be a couple of weeks.

Well just a few odds and ends and my barn will be done except some landscaping, that I'll do next year. Here's a few pics.:lol:

Very nice looking. What did you do for the winch? I am going to do something similar for my Jeep top and for hanging deer.

Was the metal ceiling expensive or hard to work with?

The hoist is in between two 2x8 trusts, and I sistered all the trust at the splice joints. This was done per a spec drawing from the engineer of the pole company. Originally I was going to use osb for the ceiling however there was only a difference of $365.00 to go with the steel. It would have cost almost that much for paint plus the hassle of painting it. As far as the steel we used 21 and 22 footers, for overlap. My son and a friend of his put it up using a bakers scaffold and a 8' ladder, there both in there 20's it wasn't difficult at all for them. I picked up my diesel tank which weighs 650lbs with no problem an no deflection of the trust.
