Elevator mechanic

An elevator mechanic is someone who constructs, modernizes, repairs, or services conveyances. Typically elevator mechanics only work on elevators, escalators, dumbwaiters, wheelchair lifts, moving walkways, and other equipment providing vertical transportation. In many countries, particularly in North America, the elevator mechanic belongs to a trade, called Elevator Constructors. In this profession, labor unions have a large impact on who works as an elevator mechanic, depending on the country they work in. Local codes and laws only allow certain people with permits, to work on conveyances like elevators.
