how many lifts, and how many floors, with how many people are you imagining? Yes, there's a dumb simple case where there's no need for a computer with an OS, but after the umpteenth car with umpteen floors, when would you put in a computer?
and then there's authentication. how do you want key cards which say who's allowed to use the lift to work without some sort of database which implies some sort of computer with an operating system?
It's a diesel repair shop, not an office building. I'm interpreting "lift" as a device for lifting a vehicle off the ground, not an elevator for getting people to the 12th floor.
