Abstract

The application relates to a method for modernizing an existing escalator or an existing moving walkway. The method can include removing all the electrical and mechanical parts from the existing framework of the existing escalator or of the existing moving walkway, the existing framework having two framework side parts and a base structure connecting said framework side parts, and the framework side parts being connected to each other by means of cross members disposed at a distance from the base structure; and replacing the existing cross members of the existing framework with new cross members, the two framework side parts of the existing framework being connected to each other in a mutually stabilising manner at least one point at a distance from the base structure of the framework, during replacement of the cross members.
