I have a 30x 36 attatched garage. I need help setting up a high point to attach a hoist. I have attached pictures of the wood beam going across the span. They are not one solid beam they appear to be multiple two by tens glued and bolted together supported by a Lally column as shown in the picture. The garage is now fully insulated and sheetrocked. Thanks in advance.

The usual recommendations here will be to consult a building engineer to see if the structure will support it. At least tell us exactly what you want to hang from the structure (chain hoist, rope hoist, electric hoist, etc) and whether it has a hook or what, and how much weight you intend to lift. If this is one time, and the weight is fairly limited, say 300 or 400 lbs, it might be OK to wrap a chain around the beam and hang a hoist from it, otherwise, be wary of doing anything like this.
Since you say it is sheetrocked, you are going to have to punch some holes in the sheetrock to wrap a chain or strap around it. If you are asking if its OK to lag screw an attachment to the beam, I don't think this would work.
Not sure exactly what you are trying to do.

The beam would have been engineered just for the weight of the building above it. not things hanging from it too. Personally, I would figure out another way such as a stand alone bridge or gantry style hoist.

I would use thenexsisting column and run an I beam under the wood beam and then install a trolly for the winch to go on

Unless that column has been designed for the load, you are in the same situation or potentially worse. Buckling is a far more nasty animal, it is a sudden failure (i.e. Potentially zero warning). I think the phrase in basic structural design that is repeated over and over is something like "DON'T MESS AROUND WITH BUCKLING!" I could be totally wrong ..., but there are a lot of different forms of deformation and putting members into a potential situation where they could be exposed to buckling is not one that I would want to experience if it was supporting my shop.
How would you attach the W-Shape to the Lally Column? Would you weld it to the side of the Lally Column or temporarily support the wood beams and run the w-shape so that it passed under the wood beams? If you attached it to the side of the Lally Column you would be attaching the w-shape to a 16 gauge wall thickness piece of metal! Lally Columns derive most of their compressive strength from the concrete inside and without the w-shape running on top of the Lally Column I cannot imagine you would be taking full advantage of the concrete inside the upright. If you attach it to the side of the upright via welding you would have to use a pretty light w-shape to match the wall thickness of the upright or you would be putting a ton of heat into the wall of the column which would be fairly detrimental to the base metal in the column.
If that Lally Column is not anchored to the floor fairly sufficiently I would think the weight of a load put onto the trolley attached to the w-shape would jack up the momentum of the column and that would put you into not so great situation as well.
The builder or designer must have used some load factors for designing the building or if it was a more general rule of thumb build for the shop you can still figure out what the load ratings are. If it is a small load (e.g. weight of a person) then one would assume it would possibly be able to sustain that weight. If it is a more significant load (e.g. 1000 lbs) one would possibly make the assumption it would *not* be safe to support that weight without proper verification.
I would look at building a mobile A-Frame / Gantry setup. You could probably fairly easily copy another vetted design and be in pretty good shape. Just because something looks strong doesn't mean it is. It may be designed right on the edge of "value engineering" and holds up the amount it was designed to with the minimal required safety factor.
Just my humble opinion ...

Thanks for the replies. To follow up the house has an unfinished room above that will be finished into a second living room/ man town. I know the building was engineered for extra weight above. Second I'm not looking to lift more then 500 pounds. Typically it will be used to lift the deck on my mowers to Change blades or to lift a 200 lb plate compactor into the bed of my pick up. I had envisioned bolting something in but it sounds like no one here likes that idea so I'm reconsidering. Another few pieces of garage **** for u. Thanks

The sure answer is to consult with an engineer but 500lbs isn't that much. Would you hesitate to let two 250 lb guys stand back to back upstairs over that beam? The tricky part comes into play when you consider letting two 250lb guys stand back to back while you have 500 lbs loaded on the hoist.

HF foldable cherry picker, if you don't have one you need it and it should be the first piece of rigging equipment a guy owns,, might be the only piece he needs for a small garage.

They are cheap, work well.
