The elevator industry depends on what you do, whether it is administrative management, engineering technology or sales.

Needless to say, administration and sales are irrelevant.

Engineering technology must be a science. Now the mechanical structure of the elevator is almost the same. After the elevator is produced, the mechanical part rarely changes, so the machinery is of little use in elevator installation, debugging and maintenance. Just have some basic knowledge. Unless you design it.

Nowadays, the application of electronic technology in elevators is very high and more and more complicated. In the process of debugging and maintenance, the requirements for electrical and electronic knowledge are getting higher and higher.
