Abstract
An escalator or moving walk has a truss that is supported in the area of its extreme ends. In the area between its two extreme ends, the truss has at least one tension element which, at a first end, is connected mechanically to the truss, and at a second end is connected to a fastening point. The tension element is constructed and tensioned such that it exerts a tensile force on the truss that acts at least partly in the direction of the earth's gravitational force.
