Detailed Introduction Of Sightseeing Elevator

The sightseeing elevator has a car that runs between at least two rows of vertical rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or load and unload cargo. It is customary to regard elevators as the general term for vertical transportation vehicles in buildings regardless of their driving methods. According to the rated speed, it can be divided into low-speed elevators (below 1 m/s), fast elevators (1 to 2 m/s) and high-speed elevators (above 2 m/s). Hydraulic elevators were adopted in the mid-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 lifting. In the 1980s, the driving device was further improved, such as the motor driving the winding drum through a worm drive, and the use of counterweights. At the end of the 19th century, friction wheel transmission was adopted, which greatly increased the lifting height of the elevator.
