Hanging a heavy object from a concrete ceiling - How?
I have a garage that has a concrete ceiling. Above the garage is an apartment (owned by someone else).
I am interested in hanging a Jeep hardtop (roughly ~200 lbs) from the celiing, but have never dealt with cement ceilings before. I assume that starting with Red Heads would be the best option for bolts, but I still have a couple of questions.
What is the standard thickness of a concrete ceiling? Do I have to be concerned about drilling into anything important (wires, pipes, etc)?
I don't want to meet my upstairs neighbor by drilling into his floor!
Thanks!

Welcome to the forums. If it's a poured floor it's probably 5"-6". It may even have been a preformed floor brought in and then laid on top of the walls. There will not usually be any pipes in that cement.
Hanging weight from concrete takes special steps. It's one thing to hang on concrete walls as you're dealing with primarily sheer weight but overhead and you need the right fasteners.
Based on the work I do I recommend sleeve anchors first and wedge anchors second. These types of fasteners tighten further with weight to reduce the chance of them pulling out. Be sure to use the proper amount of fasteners for your job.
