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 lifting device serving a prescribed floor. A vertical lift elevator has a car that travels between at least two vertical rows of rigid guide rails. 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. According to the speed, the elevator can be divided into a low-speed elevator (less than 1 m/s), a high-speed elevator (1-2 m/s) and a high-speed elevator (more than 2 m/s). 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 was adopted, greatly increasing the lift height of the elevator.
