In the conventional technology, in order to realize bidirectional transportation of the escalator 100, two escalators (one downward moving escalator and one upward moving escalator) are provided in the escalator 100, and since the stroke of the return path 32 is substantially equal to that of the working path 31 in the escalator 100 in the same escalator, the entire energy consumption of about 1/2 is consumed in the return path 32 and components related to the return path 32, and the like, and the energy consumption of the escalator 100 is increased.

In one embodiment, as shown in fig. 1 to 4, the working section 31 at least includes an ascending section 311 and a descending section 312;

the relative positions of the stepchain 10 and the track 50 at the rising section 311 and the falling section 312 are different to accommodate the relative height variation between adjacent steps 20.

When the escalator 100 is in operation, passengers can reach a high floor from the rising section 311 of the escalator 100, and at the moment, the passengers can move the escalator 100 from the space between the rising section 311 and the falling section 312; the descent segment 312 may continue to descend to the next floor; a passenger who wants to go downstairs can enter the escalator 100 from the space between the ascending section 311 and the descending section 312, and can go down to the next floor by the descending section 312.

The ascending segment 311 and the descending segment 312 share the same return segment 32, so as to shorten the stroke of the return segment 32 and save related parts of the return segment 32. The design of the working section 31 and the return section 32 (non-working section) of the escalator 100 is optimized under the condition that the mode of the existing escalator 100 is not changed, so that the overall operation energy consumption is reduced, and meanwhile, the cost of the escalator 100 is also properly reduced.

The rising sections 311 correspond to the number of falling sections 312. In the present embodiment, the number of the rising step 311 and the falling step 312 is one.
