Careful

The industry has struggled with these for years. The concept is great. The problem is they don't work.
They have considerable problems with synchronization, keeping both sides together and level. Every company I know has tried it and now one continues production after a short introduction.
If you want to go this way, be prepared for major service issues.
We tore three of them out of the Honda R&D facility in Maryville. I know a dealer in Eureka, IL that will give you his if you come take them out. They just drive over them - don't use them anymore.
For Honda, we fabricated a special superstructure/pit that allows a flush floor and they remove the covers when they want to use the lift. $15,000 each.
Again the problem is the concept is great.
