According to the speed, it can be divided into low-speed elevators (less than 4m/s), fast elevators (4~12m/s) and high-speed elevators (more than 12m/s). Hydraulic elevators began to appear in the middle of the 19th century and are still used in low rise buildings. In 1852, E.G. Otis of the United States developed a safety elevator for wire rope hoisting. In the 1980s, the driving device was further improved, for example, the motor drives the winding drum through worm drive, and the counterweight is used. At the end of the 19th century, friction wheel drive was adopted to greatly increase the lift height of the elevator.
