The earliest appearance of similar lifts should be traced back to ancient China and European countries. At that time, people and goods were transported vertically by tools such as hoes. Modern lifts are the result of the invention of the 19th century steam engine. In 1845, the first hydraulic lift was born, and the liquid used at that time was water. In 1853, American Elisha Otis invented automatic safety devices to greatly improve the safety of wire rope traction lifts. On March 23, 1857, a five-storey store in New York, USA, installed the first passenger lift using the Otis safety device. Since then, the use of elevators has been widely accepted and developed at a high speed. The original lift was propelled by a steam engine, so the building to be installed must be equipped with a boiler room. In 1880, the German Siemens invented the use of electric lifts, and the veritable "lift" officially appeared. Since then, the use of elevators has been widely accepted and developed at a high speed.
