I remember using something similar in US paper mills during the mid-late '80s. We called it a manlift. It was basically a vertical rubber conveyor belt with a small platform and a handhold located every 10' or so. It ran through holes in the floor. You just approached it, stepped onto the platform, and grabbed the handhold. There was a limit switch to stop the belt if you didn't get off at the highest floor, because it did just return down the other side.
