OVERHEAD LIFT QUESTION

[oosik]

Willy expressed my concerns. So - you get it all hanging from the truss. What about the winter snow load. My suggestion - do it some other way.

With an attic truss, the top chord is the "rafter" on which the purlins or roof sheeting are fastened and the bottom chord is the floor joist for the second floor. Do a search for "attic truss" and you'll see what I mean.

I'm aware that there are specific trusses for making attics where the floor is capable of a load, but we don't know that op has such attic trusses making a proper attic, or normal/non-attic trusses with an ersatz attic space above and no engineered floor load.

Without clarification from him, everything else is pure conjecture.

Even if they had a rated floor load which they probably do that load is evenly distributed not swinging from a cable. And maybe it would work but this whole project is sketch.

If you really want to do this reinforce with steel I beams
then you can just hook onto the I beams and no worry
By using 8 I beams you can cut holes in floor put in your
support beams then attach the frame beams above the floor this will enable you to hoist what ever to right under
the floor You will have 4 corner posts two beams connected
to hold them together then in the middle or there abouts
you will have two beams connected to the two beams that
hold the corners together. Hope this makes scents I can't
draw any pictures am using win 10 sorry

These ideas are ridiculous but im invested now

X2 on pallet racks. I recently put two 8' x 8' sections in my new barn with 2 shelves each, plus 2 extra shelves. They take 1600 lbs per shelf section, which is way more than I need.

To me one of the advantages of pallet racks is that with the basic setup of 2 uprights and 4 beams I can swap in thicker beams and hold up to 3 ton+ capacity per beam level, which is small car capacity.

Ummm.You need to read the OP over again a little more carefully.

Uh, nope.

 

[BlueKnife]

Uh, nope.

Where did you see anything about hanging "over a ton"?

Well he says the mower is 1500 pounds and he wants to build a frame to hold it so a ton isn’t out of the question.

Not sure why. A frame from which to hang a 1500 lb. machine does not need to weigh even close to 500 lbs. I've rigged (to be picked by cranes, excavators, log loaders, etc.) plenty of heavy equipment, logs, building materials etc. that weigh many times that much and in none of those cases did the rigging weigh 33+% of the load. That'd be crazy. I'm not saying it's a good idea (I don't think that it is), I'm just trying to keep this intellectually honest.
