Have you seen a barn where they have that pole out the gable end and a pulley? Like this one here:

In any event I'm building my 36x40 pole barn in the spring, have the plans, material list...etc but the lumber co. that designed it won't/can't design this contraption saying their software won't do it, and they're not sure how to do it. Any thoughts, photos, ideas?? I'd really like it, and google gave nothing up. Thank you!
First of all your going to have to figure out if you want convental framing or a pole barn and truss rafters,
not that if truss rafters are used are you screwed, because you can get a truss that has been designed for a room in the truss section,
but you appear to more so want a convental barn, in design and construction,
Untitled Document click on the box and a list of plans will open up you can down load,
for example here is a 26' x36' barn

there are a lot of plans on that site, free, to down load.
under the construction area there are more details of the systems, such as this for rafters,

here is details of the carrier track on draw up in I think the 40's

now our old barn has a mow hay door at the top, which opened clear to the top of the rafters, the small point on the mow has a 4x4 that extends in about as far in as it does out, and is the Ridge board on the first set of rafters, and the rail that the hay trolley rides on is attached to that via what looks like eye bolts, in side the rail is supported off the rafters by a Vee shaped flat that attach駸 to ever rafter and vees down with a eye in it to attached to the rail, (I have never seen the doors on the hay mow of our barn open, (i have nailed them shut so they would not blow off), but in the 60 years I have been here it has never been used so I can not give first hand info on it use, my dad said they had like a cargo net that when over the wagon and loose hay would be hand pitched on to the net when the wagon was full they would bring it in to the barn yard and park the wagon under the peak of the barn and lower the tripping device on the trolley, and hook up the 4 corners of the net, (we do not have the net any more), and another team of horses would be hitched to another rope that was extended up into the barn and over a pulley in the back of the barn and then back to the trolley, when the load was raised it was rolled back into the mow and when it was where it was wanted it was tripped and one side of the net would be released dropping the load in the mow, then reversed and the net relayed on the wagon and then wait for the next load,
but I think your will need Basicly an open framed mow or upper story, and I would attach a small I beam and use a trolley similar to what was posted at amazon, and then attach a pulley at the ends of the beam so one can pull the trolley along the beam, with a second pulley or hoist to raise or low items,
if it is to be stationary I would probably use the I beam again and just support it under the rafters with some type of tab similar to what the Vees are in my barn, (may have to weld attachment point on to the beam) and then cantilever it out a few feet in front of the building, then up a hook on the end of the beam or tube to hook onto,
