Opinion wanted...garage hoist hookup...

The problem with what you are showing is that you are not using the whole width of the wood for load carrying. If you measure from the top holes to the bottom of the 2 x's this is how much thickness you have. When it gives away it will tear the wood away at these bolts. You need to run the steel over the 2x's that way the load will be pulling down on the top of the 2x's not trying to split them in half like with bolts running thru the 2x's.

Put a piece of steel about 6' long or more, like rectangle tubing on top of the 2x's before you run over the top with your hoist mount that way you will have some steel to add strength to the wood. But at all costs don't run bolts thru the wood it will tear away.
