ABSTRACT:
A circular escalator which compensates the different angle velocities of the inner and outer step edges in the transition and landing zones of the escalator to maintain the axis (29) of each step (21) exactly radial to the path of travel (1) so that dangerous gaps are not formed between the steps. The invention avoids such gaps by running driving chains (24) on the main track (25), and connecting the inner and outer edges of the steps (21) to the chains via rotatable connecting rods (23). Each step (21) is joined via a vertically rotatable connecting rod (23) to chain links of the driving chain (24). The main track (25) describes a different path to the step track (27) in the transition zone (1b) and in the landing zones (1c). The vertical distance between the main track (25) and the step track (27) is proportional to the cosine of the inclination of the path of travel (1), the path difference .DELTA.s on the main track and the length L of the connecting rod (23). The length L can have a defined value between the vertical distance between the main and step tracks and the double step width.
