[0002] An elevator is a permanent transportation device that serves several specific floors in a building. Its car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. The elevator contains multiple parts, one of which is the elevator sill. The elevator sill is a metal pedal, a metal horizontal component with openings such as entrances and exits close to the ground.
