As an important vertical transportation tool, interstorey elevator plays an important role in modern urban construction. It is widely used in high-rise buildings, office buildings, shopping malls, hospitals, hotels and other places, providing people with a fast, convenient and safe vertical transportation mode. This paper will discuss the definition, classification, working principle, characteristics of use and the role of interstory elevator in urban construction.

First of all, an interfloor lift is a kind of transportation equipment that transports people or items in a vertical manner. It is usually composed of an electric drive device, a car, a guide rail system, and a control system. According to different use needs, inter-floor elevators can be divided into passenger and cargo dual-use elevators, cargo elevators, bed elevators, hydraulic elevators and other types.

Secondly, the working principle of the inter-floor elevator can be simply described as follows: when the elevator dispatching system receives the user's instructions, the elevator is driven by the control system through the electric drive device to lift the car along the guide rail in the vertical direction, so as to achieve the vertical transportation of personnel or items. The lift speed, acceleration and operating status of the elevator are monitored and adjusted by the control system in real time to ensure the safety and comfort of passengers.

The interfloor elevator has the following characteristics: First, it can realize the transportation of a large number of people and items in a limited vertical space, make full use of vertical space resources, and improve the use efficiency of the building. Secondly, the operation speed of the interfloor elevator is faster, and people or items can be quickly transported from one floor to another, meeting people's needs for rapid transportation. Again, the use of the inter-floor lift is very convenient, just press the corresponding floor button, you can achieve automatic operation, the user does not need to work hard.

Interfloor lift plays an important role in modern urban construction. First, it provides an essential vertical mode of transportation for tall buildings, allowing people to easily enter and exit the building, improving the utilization rate and efficiency of the building. Secondly, the interfloor elevator can also improve the safety of the building. By equipping with corresponding safety devices and monitoring systems, elevators can achieve a variety of safety functions, such as overload protection, fault self-test, emergency evacuation, etc. These measures effectively ensure the safety of passengers. In addition, interfloor lifts can also improve the accessibility and convenience of the city, providing convenience for special groups such as the elderly and the disabled.

However, there are some problems with the use of interfloor lifts. First of all, because the elevator needs to consume a lot of energy during vertical operation, its energy consumption is larger. In order to reduce energy consumption, the development and use of green elevators should be advocated, and energy-saving elevator technology should be adopted. Secondly, because the elevator has a certain maintenance cost, different types of elevators need to take different maintenance measures according to their characteristics in the maintenance process to ensure the normal operation of the elevator and extend its service life. Therefore, in the process of elevator design, installation and maintenance, it is necessary to operate in strict accordance with relevant standards and specifications.

To sum up, as an important vertical transportation tool, the interfloor elevator plays an important role in modern urban construction. Its appearance makes people's living and working more convenient, fast and safe. But at the same time, it is also necessary to pay attention to the energy consumption and maintenance costs of the elevator, and promote the development of green elevator and maintenance technology to improve ecological and economic benefits. It is believed that with the continuous progress of science and technology, interfloor lifts will better meet people's needs in the future and make new contributions to urban construction.
