An elevator is a permanent transport device serving a number of specific floors in a building, the cars of which travel in at least two rigid tracks perpendicular to the horizontal or inclined at an angle of less than 15 ° to the vertical. There are also steps, where the tread plates are mounted on a track for continuous operation, commonly known as escalators or moving walkways. A fixed elevator apparatus serving a predetermined floor. The vertical lift elevator has a car that runs between at least two vertical rows of rigid guide rails or guide rails with an angle of inclination of less than 15 °. The size and the structural form of the car are convenient for passengers to access or load and unload goods. It is customary to use elevators as a generic term for vertical transport means in buildings, irrespective of their drive mode. Low-speed elevators and high-speed elevators can be divided according to speed. The hydraulic elevator begins to appear in the middle of the 19 th century and is still applied to low-rise buildings until now. In 1852, e.g. austs in the united states developed a safety hoist for wire rope hoisting. In the 80 s, further improvements were made to the drive means, such as motors driving the winding drum via a worm drive, the use of counterweights, etc. At the end of the 19 th century, friction wheel transmission is adopted, and the lifting height of the elevator is greatly increased.
