The entry to the Great Wall is too steep for senior tourists. Can electric escalator be installed ?

I just know the case in Badaling section. At the entry of the wall, there are roads for the disabled, which are quite flat. And the elevator is available near the entry for your convenience. However, the elevator cannot take you to the top of the mountain. To enjoy the wall easily, it is suggested to use cable car~

There’s a chair lift option outside of Beijing
