Abstract
An escalator with an endless formation of successive steps, each having a step surface, a front surface or step-riser and each side, a sideways directed cheek. Provided in the area of each cheek is at least one roller that projects transversely sideways, and is guided along laterally mounted, diagonally running roller-rails of the escalator. On each step in the area of the front surface or step-riser at least one emergency guide hook is fastened in such manner that the emergency guide hook of a higher lying upper first step supports itself against an area of the cheek of the next lower lying second step, should the step be eccentrically loaded in the area of the step-tread.
