Abstract
An escalator or moving walkway includes a support structure supported between the rests at a cable, which is arranged laterally or below the support structure. According to the invention there is provided in the region of each rest a respective lever which is rotatably mounted at the support structure and is slidingly supported by one arm at the building structure, the cable being fastened to the other arm of the lever so that the cable is additionally tensioned when the support structure bends. In this manner, the construction is very stiff so that the escalator bends only slightly even under heaving loading.
