Abstract:
An escalator with a high speed inclined section comprising:a main frame; a plurality of steps, each step having a tread for carrying a passenger; a riser at a front or rear end of the tread; a driving roller shaft; and a driving roller rotatable about the driving roller shaft, the plurality of steps being coupled in an endless manner to circulate along a circulation path; a plurality of transformable link mechanisms which couple the driving roller shafts of the steps adjacent to each other, changing an interval between the driving roller shafts by being transformed; a rotatable auxiliary roller on each of the link mechanisms; a driving rail on the main frame for guiding movement of the driving roller; and an auxiliary rail on the main frame for guiding movement of the auxiliary roller and transforming the link mechanisms, wherein the auxiliary rail has a shape, in a section between a forward path side horizontal section and a forward path side constant inclined section of the circulation path, such that, of the steps adjacent to each other, a moving track of relative position of the step on a lower step side with respect to the step on an upper step side is the same as a surface shape of the riser of the step on the upper step side.
