Abstract
An escalator is described that is designed in an installation space-saving manner and can be operated with low wear. The escalator has a plurality of treads and a guide-rail assembly to guide the treads during a return run. Each tread front intermeshing structure and a rear intermeshing structure that are complementarily configured in such a manner that they can meshably engage into one another in the forward run. The escalator is configured such that at least in a central region of the return run moving at an incline, the intermeshing structures of adjacent treads are meshably arranged with each other. As a result, the dimensions of the escalator can be reduced and adjacent treads can mutually guide each other through the meshing engagement.
