Belt manlift

A belt manlift or manlift is a device for moving passengers between floors of a building. It is a simple belt with steps or platforms and handholds rather than an elevator with cars. Its design is similar to that of a paternoster. The belt is a loop that moves in a single direction, so one can go up or down by using the opposite sides of the loop. The belt moves continuously, so one can simply get on when a step passes and step off when passing any desired floor without having to call and wait for a car to arrive.
