I’m getting ready to put a new flatbed on my superduty which weighs around 900#. Do you fellers think the garage trusses would handled lifting this?

Not one single truss, I was thinking about using 2x6 layer over the trusses spreading out the weight and lifting from 4 different points.

Why dont you gang up a stack of 2pc 2x10s that's wide enough to bridge the truck, probably 8ft is enough.

Attach this to the bottom surface of the bottom truss chord using some basic 2x4 blocks, screwed. Now measure for 2pc 4x4 posts to go from the floor to the underside of the 2x10s, tap-fit on the length.

The trusses then just supply the side-forces so nothing tips over, which would be a serious problem in itself if it had to be independent like a gantry. The vertical loads are carried by the posts.

If you did split the load into 4 places it averages to ~250# corner. But then you need 4 lifting devices instead of one, and only 3 of the 4 are likely to be holding the load at any one time.

how about a few pics cause if you have a single garage or a triple garage your question's answer would be different. dimensions too so the engineers might even give you a better answer if they see your thread.

it's hard to guess without seeing your truss or any dimensions?

There is no way they were designed for it. That said, it might work, but I wouldn't do it in my house or shop

Thanks guys for everyone’s thoughts. I’ve decided against going the rafter route. I’ve gotta another garage with a massive steel ibeam across supported by metal ibeams to the ground. I know this will support it. Just didn’t wanna have to lug all my tools across the drive and work without heat.

Glad you made the post and thanks to Matt for his idea. I may remove the bed in my truck to make replacing one of the gas tanks easier.
