[0002] An elevator is a permanent transportation device that serves several specific floors in a building, with its car running on at least two rigid rails that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. There are also step-type ones, with the treads mounted on the tracks and running continuously, commonly known as escalators or moving walkways. Fixed lifting equipment that serves specified floors. A vertical lift has a car that runs between at least two rigid rails that are perpendicular or inclined at an angle of less than 15°. The size and structure of the car facilitate the entry and exit of passengers or the loading and unloading of goods. It is customary to use elevators as a general term for vertical transportation tools in buildings regardless of their driving method.
