Well, the lift is 118' tall, so you'd realistically need a ceiling no shorter than probably 119' high. Granted, this does not account for the height of your vehicle. If you were lifting something like a Sprinter van, and you wanted to be able to stand up underneath it, then you'd surely need additional ceiling height based on whatever is the height of the van and how tall you are. In conclusion, you really need to measure for yourself to be sure this is going to work for your application. Thanks for your question!
