What does the elevator bring to people?

Since the appearance of the elevator, the elevator has been playing an important role in the people's life. Maybe some residents don't often contact elevators, but for most of the residents who live on high floors, elevators are the tools they must use everyday. In addition to the benefits of the elevator, there are many, look at the following.
Since the elevator was designed after the people up and down the stairs to climb the stairs, even to the 100 floor above the floor, also can arrive in a few minutes, this relatively for people to live and work to provide more convenient, so that they can improve work efficiency, save more precious time. At the same time, when moved some large objects, such as some human power to move objects by loading elevator can reach the destination floor directly, without the need to spend a lot more mobilize too many troops, manpower.
Of course, the design and installation of the elevator need to be put in a certain amount of manpower and material resources, and the places where the elevator can be used must have certain conditions. For this reason, the living standard of people in China is constantly improving, and more and more people live in high-rise buildings. I believe that people will have more chances to contact with elevators when they come to that time. The development of technology will also give more reforms to elevators.
