The embodiments herein provide an automatic non-conveyor stairway comprising two separate straight stair flights that move inside each other without interference. One stair flights moves horizontally. The other stair flight moves vertically. With discrete sequential motion of the stair flights, an arbitrary load is transferred along the stairway. Each stair flights includes several comb-teeth shaped stair steps. The stair steps of horizontal stair flights comprises parallel plates along the stair width attached to a supporting wall at the back. The vertical stair flights include parallel plates fixed at the bottom to a supporting base. The supporting bases are connected to stringer at the left side of the stairs. The supporting walls are fixed to another stringer at the right side. The stringers are confined to move horizontally and vertically, thereby providing the required motion of the stair flights.
