I have no idea what make it is. It is very old. It was $400 on Craigslist.
It has two very large ball screws driving the lift arms. The right screw is driven from the top through a 90 degree gear reducer, and the left screw is driven by a chain across the bottom.
There is nothing special about the floor. There is a large support area on the bottom of each column.
