A building of 6 floors or less than 6 floors has no elevator, so people feel inconveniences in life; adding the elevator in the building is difficult, because there is no space; in the existing schemes of adding the elevator in the walking stair, tracks turning along the walking stair and traction steel cables are normally needed in the field, and a drive mechanism adding heavy weight on a man riding car is needed, so the construction is hard. The invention provides a light crane arranged on each fold of stairs; the cranes on the left side and right side are respectively connected end to end with the cranes on an upper floor and a lower floor; the cranes are driven by a drive mechanism on the top of the building so as to make rising and descending motions; the drive mechanism drives the cranes on two side to make up-down motions, and simultaneously drive the cranes on two sides to make transverse motions along a H-beam; the up-down motions are combined with the transverse motions, so the cranes on two sides can go up and go down on the same time along the walking stair in an oblique manner. The no-waiting elevator added in the walking stair is simple in structure and installation, and allows people of each floor to go up and down at any time without waiting.
