The invention relates to special rail-mounted equipment for going up and down stairs, which is mounted on the stairs. The equipment comprises a track, a main U-shaped wheel set, an auxiliary U-shaped wheel set, a rack, a worm and gear, a motor, a seat and a safety tongs component. As shown in a figure, the track is mounted at the lower part of an upper stairway layer, the rack is mounted on one side of the track, the U-shaped wheel sets run in the track, and the seat is hung under the main U-shaped wheel set. When a person sits on the seat, the motor drives the worm and gear to rotate, a turbine moves on the track to drive the U-shaped wheel sets to move in the track, and the seat is driven to run along the track at the same time, so that the functions of going up and down the stairs are realized.
