If you have a Pool Table in a bar, it only makes sense to have a Pool Table lift. Therefore, if you have a Server room or Data Center, you need a lift to put the Server racks up.
That is what ServerLift is all about. They sell a device that helps you put up and take down a rack. Therefore, if there is a problem rack, you can pull the whole thing down instead of standing on a shelf trying to troubleshoot.
After all, if you have a Billion dollars in server equipment, you want to take care of it best you can.
