(3) The two sides of the movable pedal in the two stair climbing devices are not additionally provided with guardrail handrails, so that certain potential safety hazards exist;

(4) The movable pedals in the two stair climbing devices can only do inclined plane linear motion on the inclined plane (namely the stepping section) of the stair, cannot do plane linear motion on the straight plane (namely the rest platform section) of the stair, can only convey the riding object to the first stepping grid at the upper end of the stair when in ascending, and cannot directly convey the riding object to the entrance of a resident (namely the rest platform surface where the entrance of the resident is located).
